never had one of these, that's a capacitor, right? also don't know what capacitance this is, tried searching but came up short
edit: OK, since it's 1000V I guess this isn't electronics, askelectrics doesn't exist yet?
edit 2: top view
edit 3: the whole mess
(dogdammit lemmy, can't you tell me what image size isn't too large, I hafta guess?!)
I'm reaching my limit here (I do small electronics) but that cap looks like it's on the primary side of power in, so it's rated for power line in. (Hence the high voltage rating).
What is the tv doing/not doing? If any of the LEDs (power led) turn on at all, I would guess that it's not that side of the circuit. (I don't know much about TVs, but these are always the questions I ask for troubleshooting)
Edit: looking at the debris near that part, something went. is the fuse okay? Is the mess localized around there?
fuse OK. turns 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)
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?
