Ok, so an OLED purchased a few months shy of2 years ago is displaying burn in.
To be fair, the customer has news on the TV all day long and watched movies at night. The news station banner at the bottom of the screen is whatís burnt in.
After speaking with LG I was told to put the TV into store mode and let it do itís thing to clear the screen. Iíve done this process a few times while running a static screen for 15 min in between each time. Retention is still there which leads me to believe itís burn in. Has anyone else had this problem and have any tips.

I believe this to be common because the latest models include pixel refresh and screen shift built in.

Long shot but have you tried an extended (few days) of disconnected power?

Maybe the the length of time in store mode has to be an appreciable portion of the time the set has been burning in.

Let's say they watch one hour of news per night, every day. Call it 22 months now, which is 667 hours. Have you run store mode for, say, even 10% of that? 20% of that? I mean, who would think of running store mode for 20%, which might be required, but which is more than 130 hours?

And, of course, if they watch more news than that, adjust for that difference.
A good answer is easier with a clear question giving the make and model of everything.

I saw it when a customer bought a floor model from magnolia. The solution was he took it back.

Forgot to say, none of the suggested fixes got rid of the burn in.

Turnt he TV off, run it on something other than news with a ticker. Keep power cycling the TV. Eventually it will go away. If they watch CNBC all day long, then it will be there and never go away. The LG panels will eventually go through a resetting cycle that will reset each pixel in the display. YOu can usually get rid of teh burn by just turning it on and off. Use the TV on something other than the news and it will clear up.

There are long threads on AVSForum about this very topic. From what I've read, if the set has burn-in, it is irreversible. Running the "clear screen" setting will not fix things once burn-in has occurred.

The suggestions they have on the forum threads are to turn down the panel brightness from the default when you install the set since panel brightness seems to have an influence on burn-in.

LG specifically does not cover burn-in in their warranties.

WTF! No, that is NOT how that works.

The image is there because the OLED pixel for that image was been either on or off all the time. So now it is either brighter or dimmer than the other pixels around it. Same as what use to happen to plasma TVs.
The brightness vs. life span of the pixels is not linear. They wear faster when new and slowly taper off with brightness vs. age.
So the fix for image retention / burn-in, is to wear all the pixels in the area to make them closer to the same. That is what many of the built-in patterns try to do to the TV.
Understand that this is over all dimming the TV more. And it is not a perfect fix because the uneven wear is always there. And if it is severe enough, no amount is going to fix it - ever.

The ideal solution that WOULD fix the TV, is to have a negative image of what it 'burned in' to the TV and display that for many hours. That would only wear the pixels needed to even everything out. This of course is a lot more complicated to do and requires image capture and software from a media player to accomplish.

Ideally if manufacture were smart, along with the basic test pattern for screen burn-in some of them supply, they would have a option for negative display. Where a customer could put the TV on the offending channel, switch the negative display feature on, and let the TV run for several hours each night while they are sleeping. It would do a much better job at fixing the issue.

What? LED screens get burn in? OMG!
When we (at Pioneer) showed LED screens with burn-in at CES quite a few years ago people thought that we rigged the test. No we didn't. We just wanted to educate the masses that plasma wasn't the the only tech that had issues with image retention. Did anybody listen? Not really.
I know I'm behind in the resolution war but my 10 year old PRO950 still looks great and the 9 year old KRP600 does as well and neither suffer from burn-in.
They call me the "Thread Killer". Just watch!

So did LG lie to me? On the ones we have seen with image retention, they have all cleared up. My LG tech rep said the pixel reset after a certain amount of usage. Turning the TV off and then back on, will usually get rid of about 80% of the problem. My LG tech rep also said to just keep using the TV as normal and it would go away eventually. I would love to learn more about this.

OLED not LED. Surely you know the two are totally different.

The moral of the story is watching US news constantly will burn unwanted patterns in your brain.

I just did a quick web search, and it turns out that I am not the only one that LG has told this too:

[Link: televisions.reviewed.com]

"We've discussed this issue with LG's engineers in the past, and it seems that the TVs go through some kind of maintenance cycle periodically to make sure the OLED's cells are resetting properly. We're not sure exactly what triggers this, however, since leaving the TV off for an entire weekend didn't do the trick the first time. We've put a call into LG's people to find out more, but it appears the best way to fix image retention is to simply use your TV normally, turning it off now and again."

I am dying laughing at this. It is such BS! "Properly resetting OLED cells" LMFAO!!!
This is EXACTLY like that BS about refilling plasma TVs. I actually had a customer once ask me about refilling the plasma in their TV.


If it isn't burned in to bad, just watching regular TV might eventually (after a very long time) reduce the visibility of the image. As long as they are not watching that same channel with the static image again (at least for any length of time).
If it burned it in real good thou. Sorry, there is nothing beyond doing the negative image thing, that is going to do any good... ever. It 'is' damage.

This is also another reason to make sure the TV settings are correct. With a properly adjusted display, image retention (burn in) usually isn't an issue.

But this also brings up a qualifier that many people (even me) forget to ask sometimes - what content do they regularly watch. And dig deep into that question before selling them a TV.
If the customer just watches one TV channel ALL the time, 8-10 hours a day. And that channel has a static logo or text bar on it. It is going to eventually damage an OLED, plasma, CRT TV. Nothing can be done about that. They NEED to be sold an LCD display.
This is important because as strange as it is to me, there are many people out there that leave their TV on all day. And leave it on a news channel or similar with static images on it. This will destroy an OLED, plasma, CRT.

So LG is feeding its end users and dealers BS? We do TV repair, and I have seen several LG OLEDS that the burn in was almost cleared up after a few power cycles. What is causing this to almost go away after a power cycle, then almost entirely gone after a few? Obviously I am not going to get the correct answer from LG.
