Re: Beginner trying to fix LCD

I attached a picture of the power supply board, and a picture of the entire backside for reference - the inverter board came off at the very right by the metal next to the TV.

I don't see any obvious problems on the power supply board.

Do you think it would be worth trying to fix the thing (taking into account my limited experience with electronics repair)? Is replacing one or both of these boards likely to fix the problem in your opinion, or are there other easy steps I can take to troubleshoot further?

Re: Beginner trying to fix LCD

1: I don't have a multimeter (don't even have a soldering iron yet). Is the fuse the white thing with metal at each end that says (...)12A? As you can tell I am starting from zero, so I am praying for something blindingly obvious that even I can deal with .

2: Will try, you're probably right. On closer inspection the other pins have a little bit of residue too.

3: The light stays green (blue actually).

Re: Beginner trying to fix LCD

Just to get ahead of myself a little bit, if the capacitor is indeed bad, can that in itself cause the buzzing sound I've been hearing, or does that indicate an additional problem? It would surprise me that such a small part would make that much noise, and also it sounded more to me like the sound was coming from the power supply board but I may be imagining things?

Can I replace that capacitor with a simple soldering iron and some tin (never soldered anything in my life)? Is the capacitor a widely available part or would it need ordering?...

Our LCD tv stopped working. It was giving a humming/buzzing sound for a couple of weeks, sometimes blacking out the screen (at which point the buzzing noise would stop, but sound in speakers still playing). Now the screen is totally black, still a faint buzzing sound.

From what I've read this indicates a failure of the inverter board. So I have taken the thing apart and I think I have managed to locate the inverter board (see attached image). I have looked it over for anything obvious, the only thing I notice is a burnt looking area at one of the capacitor pins (see image).
