I read Tom Pajewski's 7-17-04 post: "Had the same problem with my JVC-32980.Working one day, next day nothing.changed out C926 with a 1000uF 35V capacitor that I bought at Radio Shack for $1.49. TV works like a champ. Took all of 20 minutes to fix."
Now... I'm not handy AT ALL with sort of stuff, but I thought, heck, for $1.49 I'll give it a try. I unplugged the set, took all the screws off the back and looked for the C926 capacitor - they're clearly labeled. I noticed the part bulged at the top slightly -- (that is what indicated to Tom that the part was "blown.") I bought a new 1000uF 35V capacitor at Radio Shack -- my part cost $1.75. Then I pulled out the old part and soldered the new part in and bingo, I'll be darned! the TV worked again! Tom probably saved me at least $100 - 150.
