Thin vertical line on LCD tv

I have a Westinghouse 1080p LCDtv and for over a year, it gave me no problems. Then a faint vertical line started showing up. It runs from top to bottom in the middle of the screen, and only appears when there are even or mid-tones behind it. Against most colors, particularly bright or dark ones, it's invisible. Anyone know what this is? I've been talking to the Westinghouse people and they're clueless, which has to be BS because I've seen the same problem discussed online by several other Westinghouse owners. If it comes down to it, I have a Best Buy 4-year warranty, but I wanted to see if anyone here knows what's causing this and if there's a way to fix it (other than not buying Westinghouse in the future). See attached image for an example. Thanks.

I'm also having the same problem. I bought mine thru Crutchfiled w/3Yr extended warranty, but I haven't reported the problem yet.

So, Best Buy is actually replacing the "panel" instead of a replacement set? Curious, since I wasn't sure if that was a viable solution. I've had it done on a 15" laptop, so I suppose it could be done with a 42" TV. Interesting.

Thanks. I will never buy a Westinghouse product.

I have a vertical line down the middle of my screen - it was there when I bought it but it was so faint I didn't give it a 2nd thought - as the LVM42w2 is known for some degree of banding.

The line has grown progressively worse over the year+ that I've owned this HDTV and I'm really dissatisfied with this purchase now.

I'm not sure what to do, or what I can do. I've heard the horror stores about Westinghouse's "customer service" and I'd prefer not to deal with any of that.

i have similar black bars, but they are in line with 4:3 bars on either side of the image. best buy said that warranty doesn't cover those lines and it's my fault for watching so much sd tv, which i don't. all bs, but then i showed him the vertical banding in the middle of the screen that's highly noticeable on a gray screen and he agreed to order me a new panel.

i really hope westinghouse addresses this issue or will extend the traditional warranty, because i recommended the 720p model to my parents and the 32 inch model to my grandfather.

for my next tv, i might look for a tv with better sd scaling, just in case that really will cause "burn-in" on an lcd.

wanted to bump this thread, Ive gone through 2 Westinghouse TVs in one year with this issue, Westinghouse doesnt care period. I sent one back to them for repair and i didn't see it for 6 months and they replaced it, that's the second one that broke 4 months later.

Have the same problem, just 3 months after 1 year warranty.
Called their customer service line several times as it is clearly a defect in the panel. They refused to help me out and pushed back as warranty has expired.
Their customer care supervisor was a real jerk and didn't want to answer most of my questions leaving long blanks on the phone with no responses.

Yesterday, I have sent a mail to their headquarter in CA, US and email to service@wde.com.

A few people have posted same problem in a few forums. No solution provided.

If you do have any tips, please let me know

Gentlemen,
Today I’m writing to all of you in the hope to get your assistance.

I have contacted your customer service department and talked to several people without success.
A year and 3 months ago, I have purchased a 42LCD TV Monitor (647LVM42W) from Crutchfield. The value of the TV was ~$1600.

Buying this TV was an investment for at least a few years.
For the past month, an issue arose with the LCD which makes the TV not friendly to watch anymore.

A permanent vertical black line in the middle of the screen (top to bottom).
Your customer service refused to help me saying the warranty is over by nearly 3 months which I cannot argue.
However, I truly believe and consider that I’m part of an “un-usual” scenario. The problem observed is a defect and as such should have special considerations.

The panel seems to be the cause and as you know, it is over 80% of the price of the TV.

Your customer care department telling me to buy a new TV or go try in local dealership because of these 3 months over warranty seem to be very harsh to say the least.
I do not think I am being unreasonable by requesting some assistance to resolve the problem.

If you aren’t convinced yet, just put yourself in my position and ask yourself, would you buy a $1600 TV and put it in the garbage 1 year 3 months later?
How would you feel about it?
It is not like a car and I can do regular maintenance on breaks, oil, etc… I have taken excellent care of my TV and without any reasons failed me with this panel defect.

I always considered your products to be high quality and always been pleased customer.
Please, would you be able to assist me in any ways to resolve this problem in friendly matter, this is all I’m asking.

Hope this email will show you a high consideration for your company and faith in your good will.
I’m looking forward to hearing from you very soon.

Isn't that beyond fixable? I think you may be in for a headacke, but maybe they'll replace something like the video board or the LCD panel, and then you'll still have the same problem or at least in a few months.
If it's not fixable, maybe you can get a warranty refund-- after all, it shouldn't be Best Buy's fault, really.

I get the same line down the middle of my Toshiba 42" lcd. It is only noticeable in light backgrounds and is intermittent at this time.

I have a Mits LT-46231. When I watch my local HD news and they cut to a 4x3 commericial.. I see a vertical blue line on the left that lines up with the border of the square picture sometimes. It goes away once the HD broadcast kicks back in. I've seen it on CNNHD also.

Is this the same thing or possibly something caused by the broadcast?

Same problem on my 42" westinghouse just popped up this week. Very annoying. No fix yet?

Funny this , as im trying to find out what it is too. I have the LVM-42w2 its 1 yrand 1 month old bought online at crutchfield, no extended warranty and i just noticed the excact same thing on mine this weekend while watching a movie, im so gutted as ive heard horror stories about getting any customer service from Westinghouse.

Does anyone no what options we have as im out of warranty ? Suggestions ?

Thanks,
Jimmy.

Wow, I have exactly the same vertical banding on my Sony 32S3000. Also, there are like 3 vertical lines, but mostly visible on white backround. Sometimes I can see it on cable, but can't on HD playback.

mdLCD

Thin vertical line on LCD tv

It's a symptom of what everyone refers to as vertical banding. Have you tried a light grey screen to check for banding? It may be that there is a brightness difference between two bands that causes the line to appear darker. You may also find that there is more banding in other areas of the screen than you have realized.

I've got a thin dark band that's gotten more noticeable as of late that runs down the middle of my screen too: lvm-42w2. I reboot my tivo which gives me a solid, light grey bootup screen and I can see the thin dark band going down the middle of my screen. It also shows that there are different shades of vertical bands all the way across my screen. As a whole, the left half of my screen looks darker than the right. From new, I have had vertical bands on the left and right edge of the screen (about the size of the black bars if you watch tv in 4:3 format). I've been able to ignore those as they aren't in the main view. I don't know if it's because of the backlight, video board, the screen or what. If it gets much worse, I'm going to contact Westinghouse too.

Sorry, but there's no simple solution; though some claim that unplugging everything from the tv and unplugging the tv power for 24hrs will help. I think that's a crock, but you can try it.

Thin vertical line on LCD tv

Yeah, lvm-42w2 is what I have, too. When I change sources and the screen goes all grey, the line is very, very noticeable. It's not a solid line, but more of a gradient outward in both directions. Oh well, guess it's time to use that Best Buy warranty. :P Thanks for the info.

I am also having the same problem with my Westinghouse SK-32H240S. It's just under 5 months old, and has the faint line at the right 4:3 edge.

It doesn't appear when the screen is really bright, ie white. If I run evangelo2's burn-in DVD, the line is most visible on gray, blue, light blue, and light red (pink) screens if you know what I mean. I've left the DVD running overnight, for about 15 hours in a row, and it hasn't faded much if at all.

This is my 2nd one, I returned the 1st to Wal Mart before the 90 day return time frame. It had developed a really dark line, but at the present, this one is about as noticeable as the original picture in the thread.

The wife just refuses to watch SD content stretched -- what're ya gonna do?

The Westinghouse tech support dood said it was definitely covered under the warranty, but I'm just not enthusiastic about shipping a TV off and waiting x number of months. I've emailed them back a few days ago, but still waiting to hear something.

Any suggestions are welcome.

Glad I found this. Nice to know I'm not alone. My first (and LAST) Westinghouse purchase is my new TX-42F43os. The first one arrived DOA. Well, it turned on fine and I watched it for an hour or two, turned it off, and it never came back on again. So I returned it for a replacement. This one had the line out of the box. At first I thought it was just from the old DVD player I plugged into it. Here's the deal: when I'm using coax or HDMI inputs I can't see it. But when I'm watching anything using the RCA input (dvd player, cable box) or composite video (Xbox 360, Nintendo Wii), there is that thin grey line going down the exact center, only a few pixels thick, barely visible against light colors (but still there if I get close and look).

Just e-mailed Westinghouse about the problem. I purchased it online, and had to actually pay for the replacement and wait for a refund on the returned unit. Got the refund, except that they didn't refund shipping as I was told they would. Can't afford to keep sending these back waiting to get one that works right upon arrival. Very annoyed.

an update...
the tech was out this past Friday to repair the TV. Unfortunately they sent him the wrong board, which we didn't find out until the TV was completely taken apart! Now I (we) have to wait for the correct board to come in and schedule another visit. The tech tried to get them to just replace the entire set, but the warranty people want to repair it first... We'll see how it goes...

Wow, so this appears to be a common issue across many brands from two years ago. I have a Toshiba (I'm on my third one) from the 2006 model year. There's long thread on this issue on the Tosh's. Search for "The OFFICIAL Toshiba REGZA 'Ghost Bar' Thread " and also under "The OFFICIAL 2006 Toshiba REGZA LCD HDTV Thread", and read up there. Here's some pics I took of my set. In the Toshiba sets, this issue first starts with a dark line just to the right of the 4:3 outline. Then a light colored line on the left side of the left most 4:3 outline. Then finally, it appears as a dard line very center of the screen. And like everyone else, it's most noticable on grayesh backgrounds, and during paning of the camera. Anyway, here's some pics I took: http://picasaweb.google.com/glennstr...ibaLCDProblem#

I'm getting ready to call Toshiba again. I love the picture otherwise. The colors are just spot on. Flesh tones look so natural. Not much motion blur, and the options on this set (42lz196) are great. It was a top of the line model in 2006. If so many manufacturers used the same panels, then no wonder they can never get replacement parts. Besides, what's the chances that the replacement parts have had the original obvious design flaw fixed?

This is why I have 3 lcd tv's all with 3 year warranties. because I know that something like this will eventually happen and I will not have to spend a cent on fixing it.

Unique things:
- It's not visible on a white screen. It gets more visible as the screen gets darker, until you get to black in which case it's not visible again.
- It's in the exact center of the screen. If you look at it, you'll see that the right side is straight line from top to bottom whereas the left side is wavy and whatnot.

It looks almost like it's 2 panels stuck together and the glue on one side is coming off or something. Somehow it's effecting the backlighting though since if it's bright, even on colors, it's not visible.

Look at the bright blue and dark blue pics for an example.

The upside is that it works perfectly fine as a PC monitor since that's mostly white but it's getting pretty obnoxious during movies, so I'm going to change it out as soon as I decide on a new TV.

(BTW don't let the colors fool you, the camera was adjusting the ISO on the fly, so there really is a major difference between the two blues despite appearances.)

Anyone know if this is fixable by a technician?

Panel change... You have to get your panel replaced, nothing else to do bout it, Contact reseller and get it replace?d.

Hi, same issue here, Sharp Aquos 42" 1080p about a year and a half-2 years old.

You can only see the line when the image is dark, I stumbled over this thread looking for, well this It seems there's alot of it about.

I am almost shocked at how common this problem is!. I bought a 42" magnavox from costco about THIRTEEN MONTHS AGO. Guess how long my warranty is! This thin line began just a couple of weeks ago and seems to be getting worse. My first thought was this was a point where the inner screen may have been joined. But that seems just too cheap to believe. I will keep looking for repair options. Any tips will be appreciated!

Will do! I just realized that my TV doesn't have a VGA input so I'm going to use the DVI input instead. Unfortunately to do this I have to get my laptop's port replicator from my office so I won't be able to do it until tonight. Hopefully the DVI input will yield the same results. I only recently picked up this tv so I'm still learning its ins and outs.

I unplugged my tv for the wall outlet and leaving it that way for about 8 hours to see if that faint black line goes away.

Well I tried the white screen fix and it didn't work for me. It could have been that I was using a DVI connector instead of a VGA connector (my Aquos doesn't have a VGA connector) or it could have been that I only allowed it to sit for about 30 minutes. A more conclusive test would be to use a VGA connector and a true white screen for an hour or more.

I bought a Sharp Aquos about two years ago from Costco. I love the TV, but I'm having the same problem with the vertical faint line down the middle of the screen. Has anyone found any solutions for the problem and what can be done to fix the veritical line. Please let me know.

I have the exact same verticle line in my Magnavox 42" 1080P LCD HDTV - 42MF438B. Ironic how most of you said you're tv's were 42"s. Different brands, same pannel supplier maybe? Anyways they're coming to look at it tomorrow but all I can say is it's definately not power.

Ok, 1 Month has passed, I mailed the SC , They do not know when they will recieve the panel, so they don?t know when i might get my set back.. must be a very common problem if they are having a hard time getting a panel-replacement.. =o(

My Westinghouse 32" SK-32H590D that I bought in June 2007 has this same 2-pixel wide black line (and shadow for about a half inch of pixels next to it) down the right 4:3 border edge. I use this TV nearly exclusively for 4:3 SD viewing. I also had one pixel go red a few months after buying it but didn't try to warranty it for something so minor that I couldn't notice from my normal viewing distance. I guess it was cheap for a reason; it was a piece of junk. Remind me not to use my Discover Card for electronics purchases since they don't have the free extended warranty that I have with my other cards.
