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

Hard to tell, a couple of the other components also look dirty. Are they just dusty, or is there some residue from a blown-up part?

What device are we looking at? I'm guessing some kind of power supply? What is the failure mode You're trying to fix?

    TV power supply. added top view in OP, a buncha surrounding components were dirty as well but a brush cleaned them up. this is the only one that seems burned. at this point I'm just looking for obviously busted stuff.

    Don't want to segue too much, but is your goal here to repair the board or to repair the TV?

    Nothing really looks totally busted, but the board has several parts that look mildly rough. Like I hate that fuse, but is it just dirty? If your goal is to do your part to not contribute more ewaste to the world and learn new things, I love it, but if you just want a working TV... new boards can frequently be crazy cheap, may be a plan especially if not sure what's actually wrong with this one.

    got this thing almost free so I'm taking my time. can't afford to call a repairdude so I'm looking into learning how to fix it. had success with a previous find, replaced a coupla caps for backlight and got an awesome TV for less than $2.

    so step 1, look for obviously busted caps and burned out shit and this post is to that end. if that fails, I'm on to step 2, determine if this can be repaired at all; like, if it's the panel, give up right there. maybe learn something for the next one. and on and on.

    If that's the case, I'd replace the fuse at least if you can get one cheap. Good luck sourcing that cap though, probably looking at finding one with compatible specs instead of the exact part and if you choose right that's probably fine. I hate doing this kind of work, so probably better people to talk to, but from what I can see and if I had to fix it, I'd replace the fuse and then see how I feel.
