My HDTV Shuts itself OFF then it Turns On by itself. (Philips Samsung)
I hope this information is useful to anybody that is willing to view this post. I purchased a Philips 47 inch HDTV from Costco. It took a lot of effort and time to lug this big set home and set it up. It produces a beautiful HD picture and I was very happy. Then suddenly it turns itself off
, then a few seconds later it turn itself back on
. I was shock, the following days it did it again. I tried all means to solve this problem. Yet I was not successful. I also notice that some Samsung HDTV had the same problem. If you have a solution to this problem, please reply. Or if you would like to share a similar problem please reply to this thread.
Iím relisting this thread because I had some problem submitting it to the AVS server. Thank You (llabine) for your nice reply.
Purchased the following HDTV from Costco in Mountain View CA
Product: Philips 47 inch HDTV 1080P 120Hz
Serial Number: Y A 1 C 0824011735
Date Purchased: 28 June 2008
- The HDTV we purchase has turn itself off and then turns itself back on.
- It does this randomly. You just donít know when it will happen.
- When it does happen you will hear a single click and then it goes off. Then a few seconds later you will hear a double click and it comes back on.
I called Costco Technical Support
1-866-861-0450 on 7-14-08.
I talked to George ID: 80236
Case Number: 753064
When I talked to George and gave him my information, he told me he never heard of that model number. We spent most of the time going in circles. And I knew it was a waste of time.
I also sent everything on this page to Philips: Online Customer Care Group
Email: (support at Philips.com) Online Customer Care Group on 7-17-08.
I called again Costco Technical Support 1-866-861-0450 on 7-19-08.
- He did not give me a case number.
- He dismissed the problem by saying it was a common problem with all HDTV.
- He told me that it was probably the surge protector. I told him that the Surge Protector was a Quality protector that was purchase new at Costco. And that I tested it by plugging in other electronic devices without any problem.
- It seems that this guy was giving me the run around.
Email Philips again on 7-22-08
- Email: (support at Philips com) Online Customer Care Group on 7-22-08. They did not reply to email.
Called Philips Tech support on the phone
- Called Philip Technical support on 25 July 2008. I spoke with Roberto. He said: unplug the HDTV set from the surge protector. Roberto gave me the Reference Number: 6R3F3.
- Called Philip Technical support on 28 July 2008. I spoke with Clint. He gave me the new Reference Number: 6RFLM. Ask him what other things to check. He said try upgrade the firmware.
- Still no solution to our problem.
? There are no power surges happening in the Condo. The unit is plug into a brand new Prime Wire Surge Protector (item 241745) which was purchase at Costco.
? I tried unplugging the set for a few hours but I still have the same problem.
? I tried removing the surge protector and plugging the HDTV directly into the wall.
? None of the remote buttons are sticking. And I placed the IR Remote Control in another room.
? The menu clock has not been set to turn on or off.
? The set is not over heating and the vents are clear. The average room temperature is around 68 degree.
? The only other thing I have connected is a new Philip DVD model DVP5992 with a HDMI cable.
? The firmware loaded on the HDTV is: LC81ULP-1.11
? On 30 August 2008, I upgrade the firmware from 1.11 to 1.13 and we still have the same problem.
I performed a Google Search on: HDTV turns itself off. & HDTV turns itself on. And this is what I found.
OK, the PCM hit me today in a VERY weird way... The TV turned itself ON for no reason... I know for a fact it was not something hitting the remote... I have been working at my laptop for the past hour, and the Philips just turned itself ON. The remotes are sitting on the table next to me, no one touched them.
Hopefully this will help Philips figure out what's going on...
My TV is connected to a large Tripplite UPS/AC Conditioner, so my power is clean. Front display is showing a steady 119V right now.
Hi Folks, OK is the PCM, Power Cycle Monster issue is when the TV will just shut off or in my case turn on by itself?
I have a new 52" 52PFL7403D/27 and a DVP5992 DVD player, both from Philips. The weirdest thing happened just before and it freaked me out cause it was late at night and I've shut off the TV and DVD player for the night. When putting my dog in her kennel, both my TV and DVD player turned back on by themselves. I dismissed the incident thinking it was cuz I stacked all of the remote controls on top of one another. But after I laid all of the remotes by themselves, it happened again; my tv and dvd player turned on by themselves.
Is it possible the remote controls are the culprit to the PCM issue? Both my TV and DVD player has the same remote hardware. meaning the remotes look almost identical. Maybe the remote power buttons are sticking a bit and at times activate, hence either turning the TV or DVD on or off depending on its

I've had a 52" for about a month and my daughter has had a 47" for about 3. Mine started power cycling right out of the box. Hers is doing it occasionally.
I called Philips tech support and they played dumb (unless they really haven't heard of it, which I doubt judging by the number of posts in this forum). I ordered a warranty repair, and the tech who came in said it was a scaler board that needed to be replaced. They ordered it, so I'm waiting for them to come in and install it.
As far as when it happened: in my case both with HD source (Dish, HDMI) and SD (DVD player, S-video). Happens every day, once every few hours, sometimes more often, sometimes less.
I'm new to this thread, but had anyone got any answer from Philips?
Had maybe 5 hours of use with my Samsung LN52A750...now it's dead. While watching it last night, the volume on it's own went super high and crackly and then the tv shut down on it's own. This happened before I could even try to adjust the volume. Now it won't power on at all. Power light flashes then there is a sound of a relay trying to power the screen, then it repeats the cycle with no sign of any image or light. Called Samsung..they will contact nearest service center to make an appointment for service sometime in the next couple weeks..arhhh!! He said it sounds like the motherboard will need replacing..which will probably need to be ordered. Not happy at all here
I had gone for 3 months, without any Power Cycling (I believe this is what is referred to as PCM on this thread, correct me). Finally last week I started getting it on my 47". Has happened about 3 times during the last week. Hope it gets fixed soon!

I've just bought a new 32" lcd tv which has started turning itself off and on and off and on. My previous one is still in the repair shop suffering from the same problem! am i just bloody unlucky? or is this just a common fault? OR could there be a wiring problem with my flat that is causing it?

My Sharp Aquos 37" LCD has been experiencing a problem where it turns itself off and back on at seemingly random times. Sometimes the TV will turn off and on several times and then the problem stops. Other times the tv will cycle on and off (several seconds to about a minute intervals) several times before the tv stays off. When this happens, the "Power" and "OPC" lights will be flashing in tandem. When the tv turns itself off and is in this state, the remote control has no effect and the power button on the tv has no effect. The only short-term fix I've found is to unplug the tv and plug it back in.

I'm having the same problem on my 42 inch - Seems to be when inputting an HD signal. I get it whilst playing my xbox and loves to turn off and on mid battle of COD or GTA.
Really bugging me, have tried changing settings like power saving modes and other stuff but nothing seems to work. It happens randomly too.
It has never happened whilst watching DTV or analogue TV.
The TV is less than a 6month old too.

Thank you all for the clarification. I've been having the same problem recently and my girlfriend and I almost went straight to a hotel thinking there was a spirit here or something - sounds silly, but at first look there was no logical explanation for this event.

My Samsung DLP Keeps Turning Off!
After my first post, I did some more online research and went to Samsung's website to read their FAQ. I was left with the impression that it was an overheating problem. Apparently these TV's are designed to turn off when they get hot.
So I pulled the back vent cover off for the lamp and looked inside. No real dust to speak off. Also, I was able to determine all the fans are working too. Vents are not blocked and, although the TV sits on a shelf in my built-in wall unit, there is about 12 inches of space behind it and it did not seem any warmer back there than the rest of the room. So overheating didn't seem like the obvious answer.
Then I read scoosdad's post (thanks! I was thinking this might be the problem). So I tried putting a piece of electricians tape over the IR remote receiver. Tried my remote and it wouldn't work so I figured it was blocked sufficiently. However, the TV set continued to turn itself off the next day -- albeit not as many times. After a few days of having the electrical tape on and the TV turning off a few times further, I figured IR interference is probably not the issue and took the tape off.
Here's the weird part. It hasn't turned itself off in about 2 days now...!
However, when I turned it off myself last night I could hear a buzzing sound that continued after the set turned off for a few seconds. Not sure if this is a fan problem or an indication that the lamp is no longer any good.

Philips 120Hz 2ms 7403/7603 Series Discussion ? Page 58 ? AVS Forum
Some people have experienced intermittent issues with the set spontaneously turning itself off and then on. The cause for this is as yet unknown. ...
I have a quick question without reading thru all the pages. My brother is taling about going to Costco today to pick up the 47" Phillips that's on sale ending today. Can someone summarize the pros/cons of this set as described in this long thread? How does this set stack up against the Vizio or Samsung models? I usually read thru the threads here, but he's coming over soon so I don't have the time. Thanks.
Although the component Costco HD feed was horrible, I got a quick idea of what this TV can and can't do. The brightness and picture quality are comparable to the Sammy and Sony they had. Maybe not quite as good, but very close. The blacks were not as good, but for the price they were good enough. I took advantage of the $300 off coupon and took this baby home.
1. The "best" Samsung models all have glossy screens. If that is OK with you, you may want to look at the Sammys.
2. The Philips has 2ms screen refresh, which beats out ALL competition by a long shot. This means no "smearage" on fast scenes.
3. The 120Hz, good motion compensation, and 10-bit screen, all lead to a very good looking PQ on the Philips.
4. Some people have seen a defect called Green Line of Death or GLoD, where you see a green line on the screen. It is expected that an upcoming firmware relase will fix this, on the theory that the GLoD happens due to a firmware glitch when you turn off the DNM (motion comp), but it doesn't actually get fully turned off with the old firmware.
5. Some people have experienced intermittent issues with the set spontaneously turning itself off and then on. The cause for this is as yet unknown.
* The Costco price is unbeatable for a set of this feature level. And, if you decide you hate it you have 3 months to return it.
My 7403 just did the spontaneous shut-off/turn-on thing that a few others have mentioned this morning. Only happened once (so far), but it was somewhat disquieting.

Just FYI BJ's wholesale club has offered the tv at the same price for past 3 months. I had issues with this model, it makes a high pitch buzz even when it is off and also sounds like it is turning on/off when it is off. Exchanged it and experienced the same problem again. There have been a couple reviews with same problems. Buyer beware!

SAmsung has a manufacturer's defect with their tv's that are shutting off by themselves - samsung will not admitt this to the public but rest-assurred I have access to inside information. The TV's need to be taken in for service with a good quality tech.

My tv keeps turning off after 30 seconds and sometimes after an hour. I have tried other outlets and it still continues to turn off- What causes this to happen and should I just dump it and buy another tv
Lately my Hitachi 43 UWX10b has started to turn itself on and off randomly.
I have programmed the tv sleep mode to turn off after 30min. and it did. Only to get up in the middle of the night to find the set has turned itself on.
Apparently this has happened a few times.
Have I got a serious (expensive) problem here?
I had to have the convergence ic's replaced just a few months ago, now this.
My Hitachi television turns itself off. After sitting for a few minutes you can hear a click in the set. Sometimes it will come right back on and other times it will take longer. What could be wrong?.
I had the same problem 1 year ago with a Sharp TV, it would just turn itself off and back on into standby. Found the problem was the fuse in the mains plug.

RCA HDTV Monitor Turns On & Off
When I turn the tv on it goes off and then comes on and goes off twice by itself. I have had it unplugged for atleast 2 months and went and plugged it back in and turned it on and it came on and went off, came on went off, came on went off and that is all it is doing. So I unplugged it again and came here. Television Information Model # D52W20

Very fustrating to say the least. Also I dont know if you get this or not but the tv when turning on and off during those 3 times, chirps like a bird sorta like a whistle..
I, Like you, hope someone can help. Good Luck too

Hey! I am having the same problems Vikki if you could let me know what the outcome was if you had to have it repaired and what it cost to get it done that would be great! thanks!

My 47-7403D has done the phantom power cycling thing twice tonight. First time we've seen it. Running 1.11, purchased three weeks ago at Costco. Has anyone gotten an acknowledgment from Philips that they're aware of this problem?

Pros: Picture is awesome, Ambient Light feature is really cool
Cons: TV repeatedly turns itself off, then back on while trying to view...anything.
Review: I purchased the TV through Philips on-line store. It was considerably less expensive than anywhere else and they were running a promotion for free shipping and set up. The ambient light feature, which I thought was kind of a gimmick when I saw the ...

I just purchased a Vizio P42 HDTV this week. It is turning itself off about every 15 minutes or so. The Sleep Timer is OFF. I changed the power connections, I even took the batterys out of the remote to see if it was sending a bad signal. It is still happening. Naturally with a box as big as a 42" TV , I threw it away. Any suggestions ?
I have a Panasonic HDTV ready, big screen tv that shuts off intermittently, sometimes twice an hour, sometimes not for hours at a time.
Overheating does not seem to be a factor.
the model number is PT-51HX40B
Serial Number is MY03470034
Any help would be greatly appreciated!
Phillips television keeps turning itself off
My Phillips television set keeps turning itself off. It also has a blue screen just before it turns itsself off. The indicator light also keeps flashing on and off when it should be solid.
Is this a fault with my television,or is it a fault with the power supply?

? Pros: Decent picture
? Cons: Turns itself off/on several times a day
Decent value for money if you don't mind missing a key scene in a movie once in while. The TV turns itself off and then on several times a day for about 15 seconds a go.
Was this review helpful to you?

states outright that, if the tv overheats, it will turn itself off until it is properly cool. Those of you whose tvs are completely turning themselves off - is your tv properly ventilated? It is quite stringent about leaving plenty of airspace around the set and not putting it near any heat source

Phillips / Magnavox LCD TV
After numerous unproductive calls to the Magnavox Customer Support Line and as a last resort I have written a letter to Magnavox to demand a full refund for an LCD TV Magnavox LCD, Model: 32MF1D/37 Serial: BZ3A0609170320. I purchased this TV on 4/21/2006. The TV began having issues on 6/15/2006. The unit would not respond to the remote or to manual commands. The unit would turn off periodically by its self and/or the screen would go blank with the power remaining on. I have taken this TV to two separate repair shops. The TV sat in the first repair shop for a month and a half July 2nd thru September 1st,
I too bought a Phillips LCD TV. Model number 42MF521D. Within 6 months the tv had issues with the power shutting off on its own. Then the last time it did that and will not come on at all. The power board is fried. When I called Magnavox I did get help and they have sent an authorized repairman to my residence to solve the issue. My only complaint about the call center is that the people that work there seem uneducated and lazy (the way that they talk on the phone and handle business over the phone). Sounds like a bunch of hungover college students that do not want to help. But they are replacing the faulty power board in the tv at no cost.
Judging from the information I found on the web, the problem could be cause by the following items.
? Replace the bulb.
? Replace the thermal switch.
? Replace the power source.
? Replace the mother board.
? Replace the fan.
? Bad assembly by the manufacturing plant.
What I like about this product?
- The TV produces a beautiful HD picture. Sports and Action Scenes are outstanding.
- The Sound is great.
- Plenty of Plug in Ports
- Costco generous 3 month return policy. Their return policy is excellent.
What I hate about this product?
Philips and Costco Technical Support
- Poor Customer Service
- Wrong attitude towards customers
- Lack of technical knowledge to solve the customer problem
- The Frame around the LCD screen is highly reflective. You can see your reflection when you sit in front of the screen. And any external light source like windows will appear around the frame.
- Having to lug this big anchor back to Costco
Thank You for taking the time
