Just got a firmware update to 5.90.04. Running engineer server. No new features. Maybe active hdr tonemapping has slightly improved, but could be placebo

Last year? Still basically the best TV ever. Sure rather have a C8PUA, but that is baby steps better in the end.

Just for the record this is a standalone post, not in response to any others in the thread, and is my own experience with more details to follow. This post is NOT intended to fan any flames.

I purchased my 55C7P from Best Buy in August 2017, calibrated it to my room using the 'Cinema' 'Technicolor' and/or 'ISF...' modes, have used it for regular TV and movie viewing and some gaming since then (lots of varied channels and content, no static logos/tickers) and have been very happy with it. It's got about 5000 hours on it, give or take.

In December I noticed what appeared to be the tv's mute icon clearly displayed on the right side of the screen during the red opening title screen of a Marvel movie. I paused the title screen to give it a closer look and discovered that all 3 "floating" mute icons were visible, the top and bottom being much more faint than the center one but still clear enough to see against the red background. And just to be clear I don't "watch the tv on mute" - I use mute over commercials and any other 'normal' time the tv needs to be muted for a minute or three. I also can't really get a clear photo of the issue, sorry.

I immediately ran the Pixel Refresh manually and checked again after it was finished. All 3 logos were still present so I repeated the PR and again all logos were still present against red, orange and darker yellow backgrounds.

I called LG support today and they told me to run the PR 2 more times and if it didn't fix the issue to call them back. I'll be running the two PR cycles today and I'll post follow-ups here as updates warrant.


EDIT: Added a photo. Did the best I could to capture what I'm seeing but I don't know much about photography or digital photo editing so while you can only barely see the top and bottom icons in the pic they are all much more pronounced IRL - I've outlined them with black circles in the pic. The photo was taken after another two PR cycles (four total now, not counting any auto cycles that have run in the month since I first noticed the issue) and I'm going to call LG back in a while.

It can happen. Nobody said it can’t. It’s just that there is a bit of fear monger if about “it will” happen. There is a difference. It’s unfortunate it happened to you and I hope you can get it resolved.

Yup, I'm aware it can happen. I had a Samsung plasma for several years before the OLED so I've been aware of burn-in potential, and sort of conditioned to it, for years and I've done what I can to ensure it never happened (and it didn't on the plasma). I'm reporting it here just to sort of document it, and to express that I think it's odd that the issue happened with LG's own mute icon as opposed to any of the static content that would more commonly be considered a potential burn-in threat.

I'll follow up after I've spoken with LG again, just to keep this up-to-date.

Hi guys:

I have a 2017 LG OLED65C7P TV. Does anyone have a link to its best settings? The settings I'm using right now seems to work ok, but there appears to be no visible difference in pictures with 1080p vs 4K transmissions. Any suggestions will be very much appreciated. Thanks.

I don't have burnin or even image retention. I have it disabled.
Nice theory - there are plenty of owners like me who have it enabled and no burn-in either. The good news is it seems to be limited to a few who get unlucky and in most cases it takes effort - see Rtings results. More good news based on a number of posts over the last few months LG is stepping up and replacing panels for those who have suffered from this problem, even when their warranty has expired.

That being said remember there are more than a few threads related to your topic, so let’s take the discussion over there if it needs to continue. They were started so as to not clog up the owners thread with posts on the same topic. Enjoy your display, it’s one of the best.

Aaaand that being said, yeah it looks like I posted my burn-in issue in the wrong thread - my bad. I should have poked around the forum a bit instead of jumping straight to my bookmarked link...

So it appears I've lost the dreaded "early 2017 look-up table manufacturing flaw" lottery. TV did it's 2000 hour pixel refresh, and now I have a notable rectangle in the middle of my screen. Already in touch with LG, they've already sent photos off to their OLED engineers. Hoping to hear back soon. I can keep everyone posted with my interactions with them and the whole process if anyone is interested.

That is crazy, so not one issue before the 2000 hour cycle??

Apparently, the 2000 hour refresh exposes the flaw, but it only affects 55" OLED's produced in 2017:

My first 65C7 had it from new before the 2000 hour cycle so not sure why they are saying it’s only 55’s affected.

I guess I should have been more specific . . . According to rtings, only the 2017 55" were affected.

My (cynical) guess is that the same flaw is present in both, but the percentage was higher with 55s, so they acknowledged it for 55s but ignored it for 65s. That old "does it cost less to recall or deal with lawsuits" dilemma

However, less cynical, since it is a documented issue that they're talking responsibility for, no harm in submitting a ticket to see if they'll fix it. I saw on another board, guy was a month out of warranty. LG came to do a software update, but the technician proactively noted his banding and asked if he'd prefer a new panel instead. No charge, whole process took 45 minutes.

I have about a week left on my warranty, but good to know that it doesn't matter.

I love my 65" C7T! Amazing picture quality! DolbyVision is breathtaking.

I'm still waiting for USB to support TrueHD/Atmos and PCM though. I have contacted their support guys and they said they'll pass the request onto their team.

In the past, I had some issues with auto dimming with bright white imagery (anime mainly). I wish there was an easy way to disable that completely... I run my PC through my Integra pre-amp, then into the TV, so I had to do a bit of tweaking to the GPU output settings to make it less noticeable.

Occasionally the HDMI ARC function fails and I lose centre channel, but usually unplugging all inputs for 10 minutes fixes that. Never know if it's the TV or the amp's software that is the fault...

I just wish more movies came out in full 1.85:1 though. I guess because of the increased pixels over 2.39:1, there is so much more detail! and it really shows on such a beautiful monitor.

Has anyone noticed flickering in some light to medium greys?
It’s very faint when it happens. It started on my 7 series after the last firmware was introduced.

I notice it all the time on the Apple TV since it’s default app transistions tend to be a flat grey. I tried to capture it in a video, but it’s one of those things that video can’t really capture.

Does running Pixel Refresh manually reveal this issue or is it a different sort of PR?

I have a C7, and all of a sudden YouTube will not load anymore. I haven’t updated to the newest firmware as all has been well lately except for YouTube.

Would updating the firmware fix the YouTube app problem? Suggestions?

Thanks!

Thanks!

Well, I unplugged the TV and installed the newest firmware, and YouTube is working again. Hope the newest firmware doesn’t present any issues. I haven’t followed this thread in months.

I can keep everyone posted with my interactions with them and the whole process if anyone is interested.
I apparently have the same problem on my 55B7P. I notice it if I run certain colour screens on youtube but notice nothing on normal tv programming. My question is: what happens if you do nothing with this problem. How would the panel be affected long term? I should add that in addition to the rectangle box there is also a noticeable line running down the middle of the panel and one side is darker then the other. Again its not noticeable on normal viewing. Anyone have any idea?

My 55B7 ran it's 2000 hour pixel refresh today and I am happy to report that all looks well. Viewed some of the color screen vids on Youtube and the screen looks very uniform and HDR and SDR content still looks amazing! Happy camper here.

Had this happen twice on my LCD/LED, while watching basic broadcast. I rebooted the digital cable box both times to get back to normal. I don't suppose this fix is adaptable for the OLED issue.

I'm a non-OLED owner and first-time lurker of this thread. I thought I'd look because my sister-in-law owns a C7. No issues with hers, as far as I know.

I think it's commendable of LG the way they're handling image retention and burn-in issues, and calming to some extent owners stress. They're doing the right thing, if they want this segment of the industry to grow.

Hopefully, they get it all sorted out, sooner rather than later.

I was ignorant of Plasma and OLED issues, never owning either. Thank you all for the information provided.
