F8500 image sticking
I believe I've burned an image into my PN60F8500, against my understanding of what was possible. I'd like to check whether there's anything left to try. I purchased the screen in December; there are approximately 500 hours on the panel.
Put simply, I began playing a game (in game mode, at full 20 cell brightness) two weeks ago. After five days or ~30 hours of screen time, I noticed retention of the game's HUD on a white screen. I adjusted the HUD to change its position, and continued to play.
Since then, I have:
(1) twice put the panel in "pattern" mode overnight, which scrolls a white-black gradient.
(2) noticed no additional image retention at all (no matter how brief) of the adjusted game HUD, despite having played the game much more. No changes to brightness or other settings.
The retention of the original game HUD has not diminished.
Is there anything left to try? I believed this kind of burn-in risk to be a solved problem, especially on this relatively high-end panel.
