Perhaps you'd have better luck with a gamma-adjusted photo? I reduced the gamma to 30% on the attached photo, and it's really easy to see now.
I have a cheap $600 tablet with an IPS panel which as you all know have horrible contrast and it is clearly visible in every photo. If I can see they can see it. I don't see LG reps using 1995 RGB PC monitors. After speaking to a manager after becoming frustrated with the 3 representatives I dealt with she looked at the photos I sent and could clearly see the issue immediately.

If there are any Camera Buffs reading this part of the forum, any idea why my Nikon D90 won't take a full on pic with the red background? (dial set to auto)

Thanks for posting this! I am amazed people are denying this is an issue when I have seen multiple instances of this on display models alone and that is within a 50 mile radius of where I live.
What happens on display models is, again, meaningless, at least until they frontload the comp. cycle. The compensation cycle is a lifeline for these sets, which would most certainly be plagued with endless burn-in if that circuitry wasn't included. Yes, there are video loops being played (of only several minutes, correct?), but there is still the issue of cumulative buildup particularly when it relates to logos (which is what I've commonly seen on demo units) when these TVs are powered on upwards of 10 hours a day (and mercilessly shut down with a power switch in many cases).

Keep us updated with LG's response! I will be doing the same. Dropped my set off last Thursday to a service center and still haven't heard anything back yet. When I do LG's response to their consumers will be posted.

Just to keep things consolidated in one thread, here's link1 link2 to another confirmed case of BI for a 2016 OLED. This really sucks! I was hoping to someday replace my IR magnet F8500 plasma with an OLED. It would be used exclusively for cable channels with bright logos so this thread is a real concern. Hopefully this is some kind of manufacturing defect. It would be great if any of the owners like @Pottypotsworth who got their panels replaced could give us a status update on whether the BI returned.

I used to believe Burn In was non existent on those OLED.

Now I'm not.

Those proof are starting to get pretty unavoidable.

it does seem to show burn in

we used to have similar discussions about LCD burn in: most members said it was not possible until some of us saw logos burned in on our LCD screens: one of them was my Sharp LCD, which was replaced under warranty: hard to say it cannot happen when you see the photos

Damm should I be worried, I am getting my TV now
Thats also why I didnt buy the A1E, to me Oled is still new, and some stuff will be improved, also Sony use LG old 2016 panels
Investing $2k on a nice Oled, it is more than enough... otherwise too many risks, especially that they might not fix the TV if there is a problem, I dont trust warranties..

OLED screen burn: with photos

It is definitely is not affecting every panel I have checked with the red color filter my set is clean . 800 hours on the panel routinely watch content with banners etc. Don't really have an explanation for it other than panel variance.

Add my 2016 C6 to the list (1680 hours on the set). I'll post photos if/when I have time, but it looks pretty much exactly like OPs... Shows up on solid red very clearly. Mine is from video games (battlefront specifically).

An observation based on what I've seen reported here: It seems that solid yellow being displayed is the biggest culprit. The areas that are burnt in on my set were static yellow images.

Let's see if we can find something in common about the panels with burn in. Can the owners who found it report:

1) Usual contrast and OLED light setting.
2) Did you make any service menu changes to ASBL
3) Did you frequently run any of the longer (1 hour) "clear panel noise" cycles prior to spotting permanent BI problem?
4) Is your room temperature hotter than typical 70-80 degrees F?
5) Do you live in an unusually humid climate?
6) Approximately how long were you displaying static content/logos during your regular viewing?
7) Total hours usage.
8) Any gaming or PC usage?
9) Was screen pixel shift enabled?
10) Have you confirmed that compensation cycles are actually running? Do you notice a delayed (~10 minutes) shutdown "click" after accumulating 4 hours usage? Or check the compensation counters in service menu.

Can anyone else think of other factors to add to this list?

Yellow does seem to be the worst offender for severe IR on these sets. The top menu icon being aspect ratio is yellow.

It seems like pottypotsworth did get his panel replaced reading through his prior posts, but the 3D was messed up so they issued him an entirely new set so kudos to LG for doing the right thing!

My E6 with 1000 hours. No BI. I have ASBL turned off since day 1. I also changed the auto cycle from 4 to 1, so it runs after just 1 hour of viewing. I have run the manual cycle about 8 times. I watch a lot of sports with score boards etc, blu ray movies with letterbox bars. Day time viewing 80/85 OLED light/contrast, Night viewing 60/85. Screen shift on. Running the manual cycle a few times early on, may actually be a good thing. From the C7 thread, I read where D-Nice has been running the manual cycle during the break in period.

Sreen shift is under OLED panel settings. With it on, the screen image moves slightly, that you cant notice. It supposedly helps prevent burn in with it on.

I've always been highly skeptical of the benefits of this feature and saw little IR improvement with it on or off on my plasma. The icons/logos that are getting burned-in are usually far too large to be affected by small shifts. The inner pixels of the patterns will remain lit.

It's unfortunate that LG didn't repair the TV because now we don't know if his panel or electronics/software driving the compensation were defective. If he comes back here and says he got BI again, then we can assume neither was defective and it's caused by something about his usage or environment. Having LG replace the entire TV was great but what happens when BI occurs out of warranty?

We need to get to the bottom of why only a few owners are reporting the issue so there are no nasty surprises in store for others.

Interesting observation on yellow playing a part. I have a B6 with just about 1650 hours. If I put up a red slide I notice a small rectangle BI just visible on the lower right corner. I use the YouTube app fairly often and notice the yellow search button lines up exactly. It's not like the screen saver doesn't kick in after 5 minutes so the yellow button isn't displayed for an extraordinarily long time.

That was my thinking... All examples of BI I've seen (including my own) were worst where static images pushing towards the yellow spectrum are displayed. There's also the other example linked to in this thread that resulted from the history channel logo (which is yellow).

Furthermore, I have played plenty of other games just as often with static images that don't contain any yellow/red and haven't seen any BI as a result. That may also contribute to the relative lack of examples.

What was Sharp's response before they replaced your panel?

All of these burn-in examples have been 2016 LG OLED models. We've yet to see any BI examples on 2017 LG or Sony models.

Have we seen any BI examples from the 2013-2015 LG OLED models?

^Yes, every year has suffered usually in the form of demos and the rare owner. 2016 seems worse likely because there are more owners than ever. 2017 models have only been out a few months...given they can be driven even harder (brighter), there was no manufacturing change made to suggest there won't be a few isolated examples that surface this year also.

Good this thread is going then. Once/If concrete BI examples start appearing in 2017 models, hopefully each affected owner will include their model, hours, and usage patterns at that point. The potential issue of yellow static images seems like a reasonable place to start tracking.

If any of the BI is related to how bright the screen gets, then the 2017 models should be the worst. Perhaps the 2016 models that are showing BI are the brightest ones of the batches. Maybe the 2016 models hitting 750 nits are more prone to BI compared to the ones hitting only 650 nits. I personally doubt that's the reason.
