Question Screen burn in fix?


So this is an odd question to ask here perhaps, but want to know if anyone else have found a solution.

Have an LG OLED smart TV with WebOS. It is over 2-years old so out of warranty.

It has screen burn-in, and have been looking for solution.

Tried the built in "pixel refresher" half a dozen times.

Also tried several of YT videos like these:
https://youtu.be/LdbqwF_KCzI
https://youtu.be/uhXMDrPgIhI

Have played these videos for a week now, but no improvement.

Looked at getting a replacement screen, but it appears that a new TV will be less expensive.

So, my question is, has anyone here had this issue and found something that has worked?

Unfortunately it is permanent...

For image retention/burn in I don't think those videos really do anything and If the pixel refresher fails as far as I know there is nothing you can do to fix it except for a replacement.

Except for minimizing more burn in I do not know of anything you can really do to improve it.

Where did I get the information that LED screens are not subject to burn-in?
Obviously, I was misinformed.

LCDs can have dead pixels. As far as I know burn in was a CRT thing.

LEDs versus OLEDs versus LCDs are not the same.

From what I understand, permanent burn-in (or image retention) can impact any emissive display - CRTs, OLEDs, and Plasmas being the most popular. LCD/LED (they're the same thing - 'LED' just means it uses LED backlighting vs some other source (like CCFL)) displays can exhibit temporary image retention - this is relatively rare (on newer displays at least - I have one 'modern' display that can exhibit this if you really work at it, but I remember a handful of 17-19" LCDs from 15-20 years ago that would regularly exhibit this after gaming) but can happen. Changing what they're displaying will almost immediately 'clear' it though (As in, it isn't permanent, and a few seconds of 'some other image' is the 'fix' - I think this is where a lot of those 'burn in fixer' images come from too, since they will actually work for LCD image retention). From what I've read/heard anecdotally, OLEDs (especially the earlier ones) are pretty awful as far as burn-in susceptibility, and should be (should have been?) treated like most plasma displays - no news, no sports, no videogames, etc. They're also probably part of the reason I've noticed screen savers coming back to some home theater/CE devices.

If you're replacing the display, I'd go LCD (which will all probably be LED backlit these days, to get their energy consumption down) just to be done with burn-in as a concern, especially if you like to watch the news, sports, etc or play videogames (or use your TV as a monitor).

Agreed, have an really old (10+ years) LCD TV from Phillips, and have no problem.
OLED from LG had great vision; I do not play games, but have watched long Cricket and college football games.
Oddly, the burn-in is all over the screen and not just where the scores are displayed.
What I also learned from this ordeal is that warranty (or even extended warranty from stores for example) does not cover the burn-in. Am glad did not purchase that extended warranty!
