sounds like the tft panel connection is not good anymore? connection of the tft driver to the panel. maybe fpc directly soldered on driver board. device heats up and connection goes bad until fade to black?
Comment on this thing look burned to you?
glitching@lemmy.ml 1 week agoturns on, backlight works, image has lines all over and after a while (30 sec when left overnight off power, 10-15 secs when left a couple hours) it starts fading the image to black with the backlight still on. inspected visually all components, this is the only one that looks suspicious.

And the end of the electrolytic cap looks okay? (The blue can). If that thing spit out over all the parts, maybe it can explain the mess.
Otherwise, it feels like something is heating up in an undesired way. This could be something downstream of some filtering capacitor that is now dead?
If you had a thermal camera, it would tell you a lot, but not necessarily point at the bad part. Can you get more run time with a fan? (Not a permanent solution)
