Well, I took the tv apart to see about replacing capacitors and ran up against a couple of complications
1. Not only are the caps laying flat, they are glued to the board. The glue feels very strong and I'm not sure about prying the caps off.
2. All the caps look good, no swelling.... so, I'd have to replace them all I guess.
It's a big and complex board, maybe the $250 for a new board is looking better now.
