LG 42 plasma are red dots normal

Regarding my LG DU42PX12XC 42" plasma purchased in 9/2005 ...

I am getting some scattered red dots on the unit, usually in the center/top portion of the screen and really mostly visible when the picture is showing black
in that area.

It seems to happen mostly after the sets been operating a couple hours or more and it seems to come and go.

I did try turning off the SD edge enhancement, turned the contrast down to like 50 and even turned the color completely off.

Even with the color completely off ... I was seeing red dots. I've seen it from DVDs and well as my HD output from the dish 942.

So my question is -- should I call up the store and tell them about this problem and would the standard warranty cover this kind of thing?

Thx in advance,
Scott

have lost the tv guide on the 50px5d...just get a black screen and preview window on upper left corner...anyone have any ideas on what could be wrong...

Finally the service man arrived. He said that he gets a lot of calls on the same problem. He said the voltage in the TV is to high so he just lowered like 5 of the settings. When you open the back panel there are the voltage number that the TV is suppose to be set at. All he did was hook up his testing device and lowered it one by one. Now i don't see anymore red or blue sparkles.

50px5d...tv tech guy should be here friday but i find something else came up...lost the tv guide program all i get is a black screen and the small preview window at the upper left corner of the screen...no setup no nothing...anyone ever seen this problem before trying to figure out if its due to tv software or cable tv....about six months old and 2 problems in a row...whats next

hunter3611

LG 42 plasma are red dots normal

just to mention...had service guy here and told me the red dot thing (could also be blue or green) was caused buy one of three service boards due to low voltage in the board...wouldent say anything about it (big trade secret) or whatever just said a lot of lg's seem to have this problem... so now its how long to get the part from lg...he did say all the pixel problems and picture freezing and remote freezing and amber light turning red and a bunch of other small problems were due to the cable card and twc in nyc...recamended switching to a box rather then the cc at least till they come out with the new two-way cards.....go figure...so now we wait...

hunter3611

LG 42 plasma are red dots normal

I've been waiting for a couple of days now for a service call. I think they are backed up and busy. I want to get this problem fixed real soon because the sparkles are starting to irritate me. I don't even want to watch tv anymore because of it. Seems to get worse too..........well for the 1st hour its ok when i leave it on any longer it starts to appear. Glad you got yours fixed............i hope i get mines fixed soon.

LG 42 plasma are red dots normal

I have an LG 50 inch plasma (50px4dh), and I see blue "sparkles" or "dots", in black areas, when the set is cold. I never saw them during the summer (when new), when the house was 78+ degrees inside. Now that the weather is cool, I see them a lot until the set warms up. I'm in Texas.

They are mostly near the top, and vary depending on the image on the set. I see them with any input. A certain mix of bright and black areas seems create a lot of them.

Does anyone have an explaination of what causes them (besides a "bad board")? I wonder if the voltage required to drive the screen is temperature sensitive?

annonatx

LG 42 plasma are red dots normal

Yeah, I was about 1 month from the end of my warranty as well (glad you had an extension!) and not a big fan of "service calls" ... but I'm glad I took the time and did it. It ended up costing me nothing, so this story had a happy ending.

On our initial service call, the tech said something to the extent that they could replace 1 of 3 different cards (on the LG plasma), and the tech could could decide which board to try replacing in sort of trail and error basis. I sounded like guesswork, but I think the second tech we had knew what to change and just did it.

I verified with my wife that they did actually replace something, and she said yeah, they put in a new board of some kind.

Good luck!

LG 42 plasma are red dots normal

glad you got yours fixed...i have a tech coming on 12/6 for this red dot thing so im hoping he can find the trouble....would like to ask you or anyone else here about another problem i have noticed...when trying to set black levels i notice the screen has a light gray to it kind of like the briteness is set two high...i mostly see it in dark or night scenes and because of it i cant set the blackness to were i think it should be you know BLACK not grayish...another way to discribe it is watch the screen when you turn it on it lights up before the picture comes on...durring bright scenes it looks fine its just the dark scenes...has anyone noticed this... do you think having it recalabrated by a pro would fix this...thanks

LG 42 plasma are red dots normal

I have the same problem with my 50in. Samsung. I have red dots flicker on and off across the top and bottom of my screen. During black and grey scenes i see it more. Lately i've noticed even blue as well...........so, I called samsung up and they will send a tech out and see. I've had the TV for a year now and warranty expired, lucky i registared the TV and got a 3 month extention. I hope they can fix the problem otherwise i'll never get another plasma again!

LG 42 plasma are red dots normal

An update from the thread starter on my problems which are now resolved!

This definately wasn't related to my Dish 942 player or anything other than the TV itself. This particular LG plasma is a high altitude model, but I don't know if that was a factor or not. For those reading this thread, I checked out all the connection/cable issues and it wasn't that. It was some kind of faulty board on the TV itself. Its kind of like a computer motherboard with little boards plugged into it which can be swapped out, if they go bad. Determining which board is the hard part and where the technicians come in. This is my basic understanding on my original problem here.

So I finally got my red dots problem fixed. I ended up calling LG warranty support and they provided me with some local repair places I could call for service work. Finding this information on the LG web site was nothing short of a tresure hunt in itself. After about a 1 month wait for my service appointment, the technician did CORRECT the problem!!

According the LG, they needed to make 2 repair attempts before you can get the TV replaced under warranty. So I told him to bring parts with him.

I believe he replaced a board on the TV and also made some minor adjustments. Since this repair call, the TV has been perfect and not more red dots !!! I wish I had more details on the repair, but I wasn't home when he did the work.

hope this thread hasent ended...have a lg 50px5d...i to have been trying to find out about this red dot (sparkles??) thing...have read others with this change connections or get it on one or two inputs (dvd-video-componet etc)...i removed all the input connections so the set is not receveing any signel and still get these red dots...has anyone solved this problem yet??? have been told that pixels are square and these dots look more like SPARKLES appearing all over the screen...someone please get back with some answer....thanks

hunter3611

LG 42 plasma are red dots normal

We had a 50" LG model on display at work that would have the scattered pixels every now and again like you're describing. They'd come and go, but very infrequently. No lasting problem, though.

absinthe

LG 42 plasma are red dots normal

just bought a 42" akai hd plasma and have red 'dots' all over the screen. Sounds like the above problems as they are def not bad pixels.
Happens on all inputs and even on diff power circuits so gotta be the tv.

Did anyone find anything further about this issue and it's solution?

dreamhost

LG 42 plasma are red dots normal

I get them with HDMI or composite ... on the Dish 942 or a DVD ... so I know its not the HDMI in my case.

I have a repair guy coming out to replace something this week, so hopefully, that will fix it.

The limited warranty will only offer replacement if (2) repair attempts are unsuccessful.

The worst part is that the dots are sporadic and hard to observe "on demand". They happen every day, you just never know when or how much.

bunkers

LG 42 plasma are red dots normal

In my case the problem is 100% reproducible. I tried another HDMI cable and the same thing happened. I also tried the secondary HDMI input on the TV and still the same thing. Then I went back to composite, and all was well again.

Called Samsung and they think it's the DVD player. Called Crutchfield and they'll send me a new one on Thursday. I may run over to BB and pick up a Sony HDMI player and experiment in the meantime. More to come.

MarkT75

LG 42 plasma are red dots normal

I have the Samsung HP-S5053 plasma TV,
Samsung HT-Q80 home theater in the box reciever w/ built in DVD player,
Xbox 360.

I also get the infamous red dots, but only through the HDMI output of my Samsung receiver. At first I thought it was a characteristic of burned DVDs, but it's happening with all my originals.

I played a movie through the xbox, and all is well (connected via components).
I changed from the HDMI cable to a composite cable on the Samsung DVD player, and all is well.

It leads me to believe the problem is with the Samsund DVD player when using HDMI. I'll try another HDMI cable tomorrow and even call Samsung. Anyone else have this problem?
-Mark

MarkT75

LG 42 plasma are red dots normal

Wow, I never heard of that before. We still do have the red dots, but there are sporadic. I really should have another service call, but it seems that whenever they show up, it ain't doing it that day! (hard to fix) For what I paid for this TV, I'm really just tempted to call ultimate electronics and demand a replacement, since fixing it seems to be all "on me" ... and odds are, I'll get the shaft the way things are going. Opinions anyone?

bunkers

LG 42 plasma are red dots normal

By the way, I switched to using the HDMI output on the 942 and HDMI/DVI input on the LG plasma ... and I still get the red snow effect either way.

bunkers

LG 42 plasma are red dots normal

I have a Samsung 42" Plasma and I was getting pink dots (though I suppose they could be seen as red) . I called Samsung and they sent someone out and he fixed the problem. He said the voltage needed to be adjusted. He said with some plasmas, when they settle into the tempature of the home they sometimes get the dots and the voltage needs to be adjusted. I hope this helps someone.

lenora

LG 42 plasma are red dots normal

oh bummer. dead end thread and i too am having these red snow like moments with my plasma.

it's not source since i get it with both comcast and dvd.

otherwise, and 99% of the time, picture is fantastic. if the snow is sort of normal and will not get worse then i can live with it.

hopefully this thread will go long enough to get some answers?

thruxton

LG 42 plasma are red dots normal

thruxton, I also agree that the majority of the time the picture is fantastic.

I am starting to believe that the red snow only happens when the temperature is very cold outside -- and the space behind the TV is below say 55-60 degrees.

I don't think that I've seen the problem occuring on fair weather days yet, or even when its 40+ outside ... but on days when its quite cold outside, like 10-25 ... then I've noticed a lot of this red snow effect occurring ...

Usually on those days, were struggling to keep our huge family room at 63 degrees and the wall space where the TV stays is probably cooler, since its an exterior wall.

The repair guy said that somebody else had a similar problem, but with green dots and LG sent them a new board to try and fix it. He told me observe the condititions during which the problem occurs and make a log of when it happens and the temperature, etc.

I agree -- lets not let this thread die ... many other may benefit as well.

I'm also wondering that for the money I paid if I shouldn't demand that the store I bought it from just REPLACE the set ... since I'm not too keen on diagnosing problems for LG for free.

bunkers

LG 42 plasma are red dots normal

Are you using HDMI from the 942 receiver? If so, try using component video outputs.

tysonwetzel

LG 42 plasma are red dots normal

Thanks everyone ...

I am not using HDMI ... I am using component cables. Good advise, however.

robert123, funny you mention it ... I did exactly what you described last night
and did notice some dots under where the TV menu had been ... my set definately
has that characteristic ... and will do that sporatically (not always, but more and more
the longer the set has been ON).

I also noticed that it wasn't doing it for the first 1-2 hours and then after the
set was warmed up ... was doing it fairly often. I even paused a dish
HD show a couple times to see if the pixels freezed with it, well the red pixels
were there, but they kept moving around like red snow (or red distortion).
It definately not just a few bad pixels shining through ... it more of a red pixelized
snow effect which does come and go ... but slowly.

I lot of times if a movie has someone in front of the dark (or black background),
then these red dots appear on the edge of the persons head (or hair) ... very
obvious.

I think I'm going to have to make some calls and get this problem looked into.
For $3000 ... you don't expect crap like this after 4 months ... this should be
warranty covered I would hope.

bunkers

LG 42 plasma are red dots normal

I think I have seen what you are describing before. If you put the menu on the screen and then remove it, do you see more dots where the menu was (on a dark area of the screen, of course)? This is not normal operation and should be repaired under warranty.

Robert

robert123

LG 42 plasma are red dots normal

I had green dots...still do have green dots...have the panel of the plasma replaced...still get them, before the TV "warms up"...It is visible with most input modes, but only when they are "active"...no signal, gives no dots...they go away after a few minutes.

Jonny

LG 42 plasma are red dots normal

There is small chance it could be my dish 942 receiver, but I am pretty sure that I have seen these same red pixels when watching a DVD.

If I can confirm that, then I seriously doubt that its the source, but rather the TV causing these effects. Also, the location of the dots is always in the same region
(top center of screen), which isn't really a random artifact in my book ... not just coincidental.

I had read somewhere to turn down the color ... but when I did (made it b/w) the red pixels were still showing throw here and there ... kind of proof that it was a physical problem with the pixels maybe?

bunkers

LG 42 plasma are red dots normal

Thanks.

Now let me clarify ... these red dots are not on all the time (they come and go in real time) ... but I have found that I can pause my Dish show and actually freeze the red dots along with it ... but the dots don't always appear (which is what I would expect with a dead pixel).

I also have not done the calibration DVD on my plasma either ... and some folks seem to suggest that doing this calibration can remove red dot / red pixel effects.

If that doesn't work, then I guess I need to call Ultimate Electronics and see what recourse I have.

bunkers

LG 42 plasma are red dots normal

Check you're cable box. A friend of mine thought his tv had failed and it was the cable box that failed.

bassguitarman

LG 42 plasma are red dots normal

I just got a Samsung A550 50 inch plasma. I had red snow in bright white areas during calibration. The fix was to set the 'pixel cell' setting to 5. I had it on 10, and I guess it was overdriving the cells.

I was using a Bluray calibration disk played on a PS3 with HDMI.

What I want to know is -- do I have a defective set or is this typical if you have the pixel cell brightness too high?

rsilvers

LG 42 plasma are red dots normal

I had a LG42PC3D (not sure if this is a Version 6 or 7 panel), I had an issue with red dots. Spoke with LG who ended up replacing the unit with a newer / bigger model (LG50PC5D). LG has been great with this issue.

Simkins

LG 42 plasma are red dots normal

I too have the red snow with an LG 50PX5D. Warranty on this TV was 2 years. At 2 years + 1 month we had the loud POP which nearly killed the picture (very dim and very low resolution). Thankfully I purchased the extended warranty.

Tech's replaced what they called the 'power board' and the tv looks normal aside from the red snow. The bill was around $750 for this one (covered under the extended warrantly).

A tech then came out and cranked up a setting internally to 'the maximum setting'. This got rid of the red dots, but at the cost of picture quality and out of whack contrast (blue blotches during white wash).

Had them pick it up and they made adjustments back to factory which brought the red dots back. Now they have indicated that I have burn in which I know was not there before!

They are now telling me the red snow is related to burn in so I contacted LG who basically told me that is crock of sh!t and to get the shop to fix it.

I will let you know what comes of this. My preference is obviously to get a new tv, but it really depends on what needs to be fixed. If a board or two then maybe just under the wire, but if panel needs to be replaced the tv will likely get replaced.

LG 42 plasma are red dots normal

So I was called down to the repair shop to pick up a repaired LG HDTV. This time I asked to view it before I left with it. Changed it to a black screen and they were still present. Switched to cable feed and they could be seen on it as well. They tried to say it was normal, which I quickly shot down and said was unacceptable. They will be contacting LG to get a new panel authorized or a replacement TV. I think I am going through HD withdrawals using a 13inch CRT for main television during this period.

castilanosu

LG 42 plasma are red dots normal

Hi All Very interesting reading, I am a Service technician and a Very Honest one i repair plasmas and all sorts of othe electronic unit, any questions welcome.

As for these Plasmas As LG is the largest PDP maker in the world more and more plasmas use thier panels, specially the Version 7 panels, If you have ANY problems with a Version 7 panel ALL 3 PCB's Need replacing this is the YSUS, ZSUS and Control PCBS do not set them up as these PCBS are setup in the factory. If you have a VERSION 6 Panel the to be honest i am not sure if you have green or read or blue dots on screen just the large PCB needs changing, YSUS but i change the ZSUS as well (matched pair) just to be on the safe side....however the V6 PCbs are expensive and a the $$$ of Plasmas are comming down you may what to thing about the repair on a V6 panel.
If ANY tech Tells you dots are normal they are lying, although on the V6&7 panesl these may go away after 15-20mins of use.
Hope all this helps

LG 42 plasma are red dots normal

Ive had the same problem with my LG 42PX4DV for about a year now and its starting to annoy me big time. My unit is out of warranty so does any one know the costs of these PCB`s so i can make i guess as to weather a repair is really worth the money!!

Glovepuppet

LG 42 plasma are red dots normal

This is an EXTREMELY common problem with older LG plasmas. A lot of PXxD models had this problem. unfortunately, it requires the panel to be replaced in the TV. Hopefully you're still within your 2 year warranty period.

harrie

LG 42 plasma are red dots normal

I am new to this discussion but not to this problem. I purchased my LG 42PC3D in September 2006. I took it in for warranty repairs a couple months ago and they replaced the CONTROL PCB. When i first got the tv back I thought it was fixed but now after about 2 months I know better.... the red dots are coming back!! I am taking my tv in again for warranty repair #2 tomorrow. I am hoping they will replace the Y-SUS and X-SUS along with maybe a voltage adjustment but Im not sure. The repair shop Im dealing with says LG will not replace the tv even to the point where they have to pay 3x the price in repairs....... I bought the extended future shop warranty which kicks in after the lg warranty runs out. Im hoping that if the problem doesnt get fixed I can hopefully get a new tv from future shop.

What a pain in the ass this is to bring the tv in and then be without a tv for approx a week.... and what a pain to pay this much money for something that has these problems. I dont think Id buy LG ever again...

Philips 42 inch plasma, model 42PF9965

Problem: Occasional red dots on green backgrounds, or green dots on grey background. Gets worse over time. Power cycle sometimes helps. Eventually leads to red screen and blank picture blank. Sound unaffected.

Solution: There is a fracture in the video cable which connects the two video processing boards. (the ones mounted together under the metalwork to which the power inlet is attached.)

Much dangerous mucking about with live V opened up (but earthed!) revealed that if I froze the end on the lower board the problem came and went. The cable has small "HRS" connectors on each end and a bit ferrite bead on each end. I couldn't find the part number. It is the only real video cable in the TV - about 20-way connectors.
Minor wiggling of the lower end of the cable made the fault occur. Stressing the cable (temporary fix) has fixed the problem so now I need to get a new cable.

There seems to be much discussion of supply rail voltages but honestly, the cable itself is the cause of this problem on my set. (Temperature related because the crack is a physical defect.)

Note also power supply problem with this model which leads to set remaining on standby. Turns out PSU capacitors at top left of power board dry out.

Good luck everyone.

If you know where I can order a new cable (in UK) please would you be kind enough to let me know.
Thanks, Ed.

I purchased a 42PC3D 10/30/06. Thought I could live with them but after awhile I wised up and decided to get it fixed since I purchased an extended warranty. Took in a week ago and picked it up today. They changed the y-sus and the z-sus boards and according to them that fixed the issue. He said they tested it for a day with no hint of sparkles. I picked it up without testing, which was a big mistake. I get it home, plug it in without any input and bam. Red sparkles worse than when I took it in. Called them up and then took it right back. I'll update when I get it back after round two.

castilanosu

LG 42 plasma are red dots normal

Good thread, well I also have a dodgy LG 42" Plasma (Model 42PX5D-AB) purchased 03/2006 and yes we experienced red dots or sparkle since about 18 months after purchase. We thought we could live with it until we could afford to get it fixed but alas there was a load pop last week and the display died. I took the back panel off and checked that the resistance on the 4 fuses that I could find were low and doesn't look like a bown fuse, not sure if there are any other hiding anywhere else.

Finally decided to call a technician so will keep you posted on progress.

LG 42 plasma are red dots normal

Hello, I just registered to say thank you for the work above regarding voltage noise possibly being the problem!

I own a Westinghouse LCD with very similar red dots appearing. My TV is out of warranty and was pretty frustrated thinking I may have to buy another (am a broke college student :P ). Anyways, long story short I have my TV hooked up to an 8 socket surge protector that is shared with this PC and its own LCD. I literally turned off the LCD I was reading this thread on and within about 5 seconds the dots cleared up.

Seems my problem as again an overworked surge protector as well. Thanks again!

Valerik

LG 42 plasma are red dots normal

I've been experiencing the red and green sparkles in dark areas on the right-hand-side of my 42PC5D.

I tried unplugging things from the surge protector, and plugging the TV directly into the wall, but the problem persisted. LG is sending a tech out to my house and I'll update with the results.

shaunpg

LG 42 plasma are red dots normal

Got the same problem (Red sparkle) on my 42PX5d, the tech came and pick it up. Today my tv is back he told me they upgrade the firmware, the good new is there is no more red sparkel! The bad is that now there's pink sparkle on anything white. So he took it back, they obviouly did not test it.

Ive got this exact same TV LG 42PC5D with the same problems (red and green sparkles) picked up today (bought July 2007) by a service center. So I can expect a new TV? lol Thats not very reassuring, it just means the same thing will eventually happen...

UPDATE!

Technician was supposed to be here at 4pm, but they just sent the delivery driver, who couldn't help me! So he called the Tech, and explained all to him.
I've got a headache from argue-ing.

He said "That's how it should look, it's common" i told him it wasn't. He wouldn't take the TV, and theres nothing else he can do for me.

So, i called LG, and filed a complaint, they rang him, and he even tried to tell them the same story. So, The store i purchased it from are coming here tomorrow (19/04/2007) to look at it. I hope they can fix it.

If not, i'm at a deadend, with a faulty TV, and still 6 months warranty.

This is Ludacrus!!!

I recorded the convo.

That's rubbish! Ask them, if it's interference, what it could be. If they state it's the TV reception, unplug the ariel, and JUST use the AV, component etc.
I personaly beleive some technicians are cowboys, and they will just fob you off.

At the end of it, our trust is in their hands, and sometimes they push their luck.

Glad i found this site as well and a good thread. I am sitting here waiting for the service tech. Our plasma a zenith (lg) 52" lost it's picture last month and they repaired it when it came back we notice the lil red sparkles as well. Last week, it went again, loud pop and lost the picture. Will see what he has to say when he gets here

LG 42 plasma are red dots normal

I've been reading this topic for a few weeks, along with other websites, and here's my story.

I've got a LG 42PC1DA 42" Plasma, which i purchased November 2006.

Aprox 4 weeks ago (25/03/2007) i noticed the slight scatter of RED Dots, like a now effect of red pixels.

I called LG, and they sent a local engineer to take it away, which they did.
10 days later, it arrives back, and i was over the moon........ UNTIL i switched it on.
It hadn't changed, the dots were still there, AND the rear panel was scratched with a screwdriver!!!!! I was FUMING!!!!!

These are the parts they Supposidly changed, i will copy the text as it is:

1 x 6871QCH077C
1 x 6871QYH053B
1 x 6871QZH056B

Replaced Y-SUS, Z-SUS, CTRL PCB all within Spec, This is a HD ready PDP will only work correctly on HDMI.

I called the Techinican company that had taken the TV within the first 60 seconds of having it switched on, and to my surprise, the technicians Actually tried to Fob me off with some crappy story.

"The reason you see the red dots, is because you have too many tv channels on the tv" - yes, that's what he actually said to me. I went on to ask, WHY does it do it with the Playstation, Xbox, DVD player and my Digi Camera?

His reply was, get this - "As i've said, it's down to you having too many TV channels on your TV" - At this point i laughed out loud, in utter disgust at this Cowby!

So, i asked WHY did you change all the above parts, if it made no difference what so ever to the TV?
The final reply i got was "It's a common fault with LG tv's, and we can't fix it"

OK, i said, i will report you to LG to ensure that you are not paid your fee for fixing my TV, as you haven't fixed it............... The technician is coming to my home Tomorrow (18/04/07) to have another look at it!

I jumped on the phone to LG, and explained ALL to them. And they ensured me it's not a common fault and they will send ANOTHER company out to me to view it.
I then called the shop i purchased it from, and have asked them to deal with it, they are ordering ALL the parts mentioned above, and will come to my home next week.

I pray this is fixed.

So, i have my TV back, with just as many Red Dots, AND scratches to the rear.


I'll post a Video and pictures Later

LG 42 plasma are red dots normal

I had a service tech come to my house to look at my LG 42PC3D yesterday and he made some adjustments. I don't have red dots anymore but I do have multicolored dots now. They are not as numerous as the red dots but they are still there. The tech said the problem is with one of the circuit boards in the TV and he will order the part in. I'll give another update in a week or so after the new board is installed.

LG 42 plasma are red dots normal

I have an LG 42 PC3D with the exact same problem with the red dots. It is noticeable in the dark areas as little individual red pixels randomly flashing. If you bring up the input menu and it goes off the screen the area previously covered with the menu will be full of the red dots initially then they seem to diminish. I went back to Best Buy and looked at the exact same model that they had on display and saw no dots. I didn't want to take the TV back as I really love the picture. I compared it to the Panasonic TH42PX60 and the Toshiba 42YDS69 and liked the picture on the LG better. After searching the web I found this forum and saw that I wasn't alone with this issue. I called the local LAG service center to come do a service call so hopefully they can switch the voltage or circuit board as has been done for others on the forum. I will update later as to the outcome of the service call.

P.S. Is there are thread devoted to tweaking the settings for the LG 42PC3D?

Thanks

Reds dots for me with HDMI aswell...

I have a Sammy HP-S4233 plasma, and I notice the red dots when I'm using HDMI through my PS3. When I switch over to component, the red dots are gone. They appear on darker screens, and are scattered all over. However, when I bring up my menu, the dots dissapear, and when I close it, they come back again.

My set went our of warranty in December, so yes, I my have to pay. The service company is going to pick the set up next week, since they are not sure what the problem is and wil need to observe it in the shop. A call to Toshiba gnerated a recommendation to unplug for a few minutes and then plug it back in . . .a reboot so to speak. This solves the problem, but it comes back. Regarding worse over time, it is becoming more frequent, so yes.

LG 42 plasma are red dots normal

I have been trying to catch up on this thread. We are new to the plasma tv world. We have a Audiovox 42' plasma that is showing the same 'red snow' that has been talked about with almost all the same signs as mentioned. It is only a few months only and the second one that we have had because the first one was doing the same thing. This time I skipped over the retailer and contacted the company directly. They are willing to send someone out to have a look but did mention a possibility of burn in. If that's the case then we will have to pay for the visit. I just wanted to be clear before I have them come out. The red snow in that photo that someone already posted is almost exactly what ours is doing just not as wide spread at the moment and is worse after the menu has been displayed even briefly. Could this be burn in? Or does this sound more like a defect in the tv itself?

Thanks for any help.

It seems to happen mostly after the sets been operating a couple hours or more and it seems to come and go.

I did try turning off the SD edge enhancement, turned the contrast down to like 50 and even turned the color completely off.

Even with the color completely off ... I was seeing red dots. I've seen it from DVDs and well as my HD output from the dish 942.

So my question is -- should I call up the store and tell them about this problem and would the standard warranty cover this kind of thing?

Thx in advance,

Red dot are NORMAL only when watching PINK Elephants, Hightail that beach back to the store as fast as possible.

LG 42 plasma are red dots normal

Glad I found this thread. I've started noticing the blue pixels on the lower part of my 42 Samsung Plasma over the past few months. At first I thought it was my 360 because I only noticed it while playing Tiger Woods 07, but have now started noticing it during normal programming as well. It's not noticeable unless I look for it, but I did get the extended at-home warranty on the TV when I bought it 8 months ago so I'll probably give the shop a call to come fix. Sounds like it could be a pretty easy voltage fix or at the worst just replacing a card. Would rather do it now vs. waiting for it to get worse.

To note, there may be something to all the posts mentioning it could have to do with cold weather because that's when I started noticing it (in January when it finally started getting into the 30's and lower outside.

Hmmmm. I dunno what I am saying.

Bottom line is that it's probably dead pixels. So, yeah, it's not something you should have to deal with. Especially if it's multiple. Pika.
Your middle sentence (my bold) is correct.

A "dead pixel" in a plasma will emit no light. DUH!

LG 42 plasma are red dots normal

I have the same problem with my Philips 50". The problem is not terrible though as it takes about an hour for me to start seeing the problem and its really only in certain scenes, especially greys. My friends dont notice it unless I point it out but of course I notice it. I only have about 2 months left on my warranty and I was thinking of getting it fixed but the autherized repair shop will only do it if I bring the TV to them which isnt easy (130lbs) and its out of town. I can live with the current level of sparkling but my worries are that it will get worse later. And if it does get worse after my warrenty expires how much will it cost? Has anyone had the sparkling get worse over time? Also has anyone had to pay out of pocket to get the problem fixed?

LG 42 plasma are red dots normal

3 year old p55 (just out of warranty!!!) with faint red, green and white "sparkles" that have become obvious since the cold weather came on.

As noted above, problem totally disappears after an hour or two. Initial internal temp = 75F, after 2 hours 96F.

What gives?

Thanks.

LG 42 plasma are red dots normal

I have this model Plasma Tv and it has Sparkles - pixel dots of red , blue and green all over screen ..large saturation of this in left corner with small light area ( this area showing only on black/ dark screen only ).
It shows only on black background even with out any signal connected to tv..
Signal source was rule out . Otherwise Colors great ... Resolution seems is off a little also.
Tv is under LG warranty and was in service for this problem for the past 3 months ! Repair center replaced X and Y board but it not corrected the problem - still the same ! Only I noticed Quality of picture become not that great as was before . Range of adjustments on Contrast and Brightness is not as use to be before replacing this boards..
Now service center saying by replacing PDP -the display panel will correct this problem ..
Any advise how to fix this problem ?

LG 42 plasma are red dots normal

Just an update.
I had the same problem, I had red sparkling pixels on my LG 42PC3D.
The repair guy came out yesterday afternoon, and after tweaking a voltage regulator potentiometer on the far left panel on the back of the tv, the red pixels are mostly gone. They are 90% dimished and they are not red any more, kind of no color... So it's not 100% fixed but I can't see the remaining few sparkles any more if I stand more than 2 feet away. So virtually I consider it gone.

It probably means they did not find the source problem.
It is sometimes a fact of life in circuit repair; imagine this scenario:
Component A is putting out the wrong voltage. It never dies but keeps killing components B C and D with that wrong voltage.

I have a vizio 50 inch plasma and have noticed red dots dancing around the screen during dark scenes. It happens with different input sources and different cables. The tv is maybe two months out of warranty but did have a warranty repair that could be related. A power board was replaced because sometimes you couldn't turn the tv off. Any experience with vizio and problems like this?

LG 42 plasma are red dots normal

I have a samsung 50" plasma which I purchased 7/06. We love the TV. In maybe September we noticed red dots on the bottom 4-6" of the screen, no rhyme or reason to when the appeared. I called for a service repair, they came out and took the TV with them for testing. A few days later they returned the TV and no more red dots. About a week ago the red dots started appearing again.

The tech said there were some adjustments they needed to make to resolve the problem, I'm not sure exactly what they were but of course my concern is that they are back again.....

thanks for the ideas guys BUT...long story short after having the sparkle like red dots on screen the tv guys showed up after three apointments when they had the wrong parts...anyway they changed a video board (dont know what it was called) the power supply and the cc card board all seemed to work BUT last night tv shuts down and comes back up on its own and now component input (rgb) plays all green and the remote control stoped working all other inputs play fine with a good picture..so have to wait to have these these repair guys back and start a new adventure with this tv...dont know what happened but im guessing one of the boards they changed went bad..hard to understand how all this stuff can go bad for no reason...should have known something would go wrong when the repair guy never checked out the tv with his meters just said he knows whats wrong...sounded fishy to me...and it seems i still have the red dots after the parts were changed ...im thinking ill let this repair go on and if anything else happens or the red dot thing is still there ill start getting on lg's case for a new replacement set...oh well...

Before calling the repair tech, try placing a small fan behind your TV.
This solved my "red dot" issue as well as eliminating my temporary burn in effect on dark to bright to dark transitions - Seems that, at least with my samsung, the heat was affecting performance big time.
That was confirmed after 15 minutes running an 8" oscillating table fan behind the unit.

hope this helps

I actually have the 'green' dots problem with occasional red. Most of it appears randomly when the screen is darker and when I turn it on. After a while, it goes away slightly but is still noticeable. My ru-42px11 is 8 months out of warranty. *sigh* Could you let us know if the firmware upgrade fixed the problem?

Much appreciated!!!

svs_man

LG 42 plasma are red dots normal

The repair shop said they replaced the y- and z- sustain circuit boards and tried to update the firmware but were having problems doing so. Apparently there has been a change to the circuit board and compatibility with latest firmware.

So LG will be replacing my plasma TV under manufacturer's warranty.

LG 42 plasma are red dots normal

I have the "red dots" problem with my LG 42PC5D. It doesn't happen consistently, but seems to appear most when there the TV image has a lot of contrast. It occurs with any signal (cable box or DVD). It usually happens only after the TV has warmed up for some time.

I called LG and they told me to call the local service shop. The technician came to the house, but couldn't reproduce the red dots. I showed him some photos I had taken and he was immediately familiar with the problem. He said it is a firmware issue and he would need to take the TV back to his shop. I don't understand why he couldn't upgrade the firmware at the house (e.g. with a laptop or something). Maybe it involves removing some chips and flashing them.

I'll wait to see if the problem is actually fixed after firmware upgrade.

I've been seeing the red pixels on scenes with people's faces...it only happens near the top center of my plasma display. I tried Prongus's suggestion and put a brookstone fan pointing at the back of the display. It's positioned at the 10'o clock area and blows towards the 4 o'clock. The red pixels went away. I will say that before I watched the movie that exhbited these problems, I had the TV on for over an hour and periodically turned on and off my heater (which is not too far behind the plasma display.

So my guess is it may be temperature issues or variations. Try the fan idea and see how it goes for you...I will experiment more and keep posting. So far, after watching another 45 and repeating the same scene, the pixels are gone.

will let you all know...

EDIT: CRAP...it's still there...I just booked a tech call with Samsung. NUTS!

I've noticed that when I'm watching 4:3 programs and have black bars on the sides or if I watch really widescreen movies and have black bars on the top, I see green dots turning on and off in and around the area that should be all black. Is this what you guys are talking about? My 50PC5D is only a few weeks old. Should I be calling support to have this looked at or is this normal? I really can't see the dots unless I'm up close to the set.

man could you have picked someone better then mr anti american murtha?
anyways i noticed this problem is SOURCE DEPENDANT. it all has to do with the signal coming in and NOT the wires.
i get this when watching NBC in 4:3 hd but converted not true hd. i thought it was my brand new plasma and allmost had a fit but i went and turned on the same show on my 42 inch lcd and the same thing was happeneing and this is OTA programming.
so its not the tv but some of the posts its obviously the set but the picture aboive is the signal.
thos doesnt happen when im watchin true 16:9 hd

Didn't matter what else was plugged in/turned on. Seemed to be worse when the TV was colder. Red Dots got to a point where I had to do something. Luckily the pots were easy to find and labeled correctly. Played some Mass Effect last night, looked closely at the dark areas, the dots are 99.8% gone!

Gimpydingo

LG 42 plasma are red dots normal

Just registered on this forum to say thank you to all in this thread.. esp those that pointed out that it's a voltage issue and how to fix it.

I've had my Toshiba plasma for a little over 4 years now and only in the past 4 months did I start seeing the red dots in the center of my TV on anything that was black or fading to black.

Anyway, to make along story short, I did was a few here suggested and dropped the plate from the back of the TV (after I unscrewed about 30 screws, heh) and after about 5 minutes with the flashlight I located the little plastic voltage regulators.

On my Toshiba 1 was on the one side and 2 were on the opposite side of the TV. After tampering with the 3 I knew I was tampering with the right thing because it did crazy rainbow color things to the TV. I wish I took a picture for you all but anyway.. each TV is different so that's no good. Mine were labeled V01, V02... the loner on the opposite side was also V01. At any rate I twisted the 1 by about 5 notches.. and the other by 2.

No more dots. Blacks are really rich, again. I think it had to do with the ambient temp of our house in the winter months (when we lived in the app the heat was paid for so we just had it cranked up.. but in our new house.. gas $$ is a whole new experience).

Thanks all. Glad I fonud this forum/thread before calling Toshiba or a technitian.

LG 42 plasma are red dots normal

I have exactly the same problem and im two weeks outside of warranty. Im a computer engineer and the inside of the TV doesnt scare me so I decided to have a go at adjusting the power.

Before I started though I went through all of the menu options to see if any made a difference. Under the "special" menu I found a low power mode option. I turned this on and after about 30 seconds the image cleared up entirely.

Since I assume this has some performance impact I didnt want to leave it on so I turned it back off. But the red dots did not come back. TV was on for about 8 hours. I then turned it off from the mains and back on again. 8 hours and several DVD's later the dots have not returned....

I agree with one of the earlier posters that this could be a power supply issue. I did notice it happened more at night when more appliances/light are in use. If the power setting in the TV is as sensitive as we all think then even a minor amount of "noise" from the household mains could cause all kinds of problems.

geordieguy_01

LG 42 plasma are red dots normal

Started taking things apart last night as after a small amount of time with low power mode turned off the dots to reappear but not as bad as they used to be.

Connected to the TV is:

XBOX 360 (VGA socket HD)
- HD DVD Addition
SONY DVD Recorder (old - scart)
SKY HD (HDMI)
Sony HDRSR1 camcorder (HDMI)

All of these are protected by a MasterPlug Gold Series Surge Protector.


If I unplug the DVD recorder and leave it for a while it clears up.
If I unplug the XBOX there is no difference until I disconnect the AUDIO connections (Bizare).
Unplugging the SKY HD decoder, XBOX looks fine in HD.
DVD player on scart input never has red dots.

Discovered with some playing around that the HDMI audio inputs and the vga AUDIO inputs share a common cable connection back to the sound processor (guess it was cheaper)

So basically, using high performance and high power functions results in red dots. Audio channel is bad design and lets one problem HD input affect the others.

On a whim I swapped the Surge Protector (8 sockets) with the one running one of the office PC's (8 sockets). Red dots still evident, not quite as bad but panel was just warming up again.

Swapped the 8 socket adapter for two lower quality 4 socket surge protectors. Red dots GONE. Turned everything on at the same time, no Dots. Left it running for hours, no dots.

My basic conclusion is that my High quality surge proectors are either using too much power themselves or the 8 socket adapter (which had other things plugged in as well - Photo viewer and other junk) should not be used to its max capacity. Devices may be drawing too much power.

When I add up the ampage I get within half an amp of the maximum rated capacity of the 8 socket protector. (For reference I live in England so we use 220 AC at 13 Amps. Household mains runs up to 30 Amps).

So im happy and I hope this helps someone else. Also explains why the dots are not recreateable in service centres. They probably have one AV source going to one TV so no high power use.

All I have to say is thank you to this forum!! Helped me with my red dot issue!
Well I think I am over Plasma all together, LCD all the way. I have Philips 50" Plasma for a little under 3 years now. The red dot issue started about a year ago. It progressed to the point where any dark/muddy scenes would be plagued with red, almost a third of the screen that I could see sitting 6-8 feet away. I searched and searched, only to find out it wasn't just a problem with Philips, but many Plasmas, as you probably all know by now. I saw a few posts here and there saying it was a voltage issue. Yesterday I had enough, I searched and came across this post. A few people said to adjust the pots Va, VB and VScan. Well I didn't want to pay a tech to come out and charge me an arm and a leg for something they wouldn't/couldn't fix. 50 screws later I took the back panel off, in the upper middle of the TV was a PCB with the Vscan pot. I marked the original locations, had a DVD paused on a nice muddy scene and and gave the pots a slight turn, after a few minutes I found the VScan and Va did the the trick, I turn Vscan about one and half ticks and Va about one tick. 98.9% of the red dots are gone! WOO HOO!!! THANK YOU AGAIN!!

Now it is 9 months later and I now have red sparkles...LG has issued a tech to come an service our monitor (fYi...this is different tech company)...anyway they told me that they are familiar with this problem...I explained the possibility of a voltage regulation problem and they seemed to be receptive to this conclusion...

they 1st had someone trying to fix at my place, then they brought it in for service,
no change and nothing better..

Then,,to make things MUCH worse, they actually booked pickup for the plasma 4 times in a row without even showing up...,,, Could say I was angry,

After chasing and threatining to use any kind of media against them,,they actually now agreed to give me a new TV alltogether....,, I guess they owe it to me after approx 7 months.....

LG 42 plasma are red dots normal

Last time at my parents' I noticed their LG 42PC1DA exhibits this same red snow effect. It's mostly noticeable on a black screen, but you can see it all the time from up close, not so much from far back. Doesn't matter the connection used, HDMI, component, etc, it's always there. This set was purchased a couple years back - hence, I doubt there is any warranty left, and I'm sure the B&M they bought it from will not give a hoot. I wonder if this thing with replacing the boards would solve their problem - I wouldn't want to suggest a quick temporary fix like tweaking the Vsc, etc.

I'm sure they wouldn't be happy about paying a service rep to come in, order these parts & install them, etc, at the possible risk that it wouldn't even solve the problem. Is this something that I could order and replace these boards myself? I have a reasonable amount of tech knowledge, I build my own PC's, etc. nothing too major. Is this out of my league? Do I really need to call in a professional? Do I risk destroying their set? If that's the case, I'm sure they'd rather just live with it. In fact, they don't even complain about the red snow, it moreso bothers me when I visit them. I'd just like to be able to correct it for them.

I have a 9 month old Toshiba plasma(LG glass) that had the red dot problem. Toshiba gave me the name of a local servise outfit here in Seattle. They came and picked it up diagnosed it as a couple of boards that needed replacing and 5 days later I had my set back and working perfect. No cost to me. The repair man said a lot of LG's and Zeiniths had the same problem. Hope this helps.

bwhitish

LG 42 plasma are red dots normal

I dont know if this thread is still alive or not but i have some info on the lg set. The plasma needs 2 boards replaced to fix the red snow problem. one is called the y sustain board the other is the z sustain board. The voltage adjustment does fix this problem also however sometimes adjusting the voltage is only a temporary fix. the most effective way is to replace these two boards. adjusting the voltages simply corrects the fact that the pdp panel is seeing the wrong volts from the sustain boards. as long as the boards dont degrade adjusting the volts will fix it. when you contact a repair center they will need the full model code off the set it will look something like this: 42PC3D-UE.ACCLLJR. were as the model number is 42pc3d, the rest of the code is a version code. without that info no one can order the correct parts ( not even lg ). sometimes I have had to actually go to the customers home open the set and get the part numbers right off the boards. This is because if you look up the model on lgs site sometimes one model code will have two differnt part numbers for the same part. (i've been fixing sets for 12 years and still have no idea why they cant have one code that identifies the parts in the set.) Anyway I hope this helps anyone who is still reading this thread. p.s. dont bother contacting me / responding, im a ghost!

LG 42 plasma are red dots normal

I have this very same problem with my LG 42", it's almost a year old now but has the red snow syndrome. I was reading through the posts and saw that it is actually the voltage which causes the issue, so I thought i'd try the Low Power option found in the menu, and it's made a huge difference! Before I changed the setting, the red dots would clone the blackened areas and stay there until a new image replaced the area, and with the Low Power settings they disappear after about half a second, which is even more bearable than before, but I still think I need to get this fixed up permanently.

I had an issue with red dots on my 42PC1DA as well so I called the boutique that I purchased it from and got the answer.It is your connections,not the plasma unless you are noticing this with dvds as well when using an HDMI cable.I was only experiencing these red dots when my plasma was on antenna(yes i said antenna.I dl movies so why bother with cable).I was told that the red dots are usually caused by cheapo interconnects such as analog.I was in the same boat as you just a week ago and thought my plasma needed to be sent off but after checking for the dots on HDMI(none were seen),my dealers answer was correct.

LG 42 plasma are red dots normal

I had the LG Tech visit me two times this week. First time to diagnose the problem. He quickly determined I needed two boards replaced. Three days later he replaced the boards, fiddled with the settings a bit and maybe there is a slight improvement but the dots are still there. He tried to tell me I had the TV set on "demo mode" and switched it to Powersave On to dim the screen. Of course, with the dimmer screen the dots are harder to see, but so is everything else. I'm close to giving up on LG.
