This works! I the owner of a JVC AV-32980. I came home from vacation the other day and the thing would not power up at all - totally lifeless. A quick Google search yielded this thread, so I thought I'd give it a shot. I have no soldering experience and really had not idea what I was getting into. The hardest part of the whole thing was removing the back of the TV. You have to unscrew about 8 screws and slide the plastic back off. Once you do that you can see the motherboard, which can slide out of the TV chassis. There's several capacitors on the board, but on the bottom of the capacitor is actually marked C926 so you can make sure you've found the right one.
I bought the capacitor and a soldering kit at Radioshack for under $10. You simply solder the old one off and put the new one on, then re-assemble and TV works just like it did before!
Thanks to everyone for the valuable information!
