I received an RCA 52" projection TV for free today from a guy that said it turned off on him as he was watching it. I pulled the rear panel out and checked for continuity/voltage with a mulitmeter and found that there was voltage (120v) in certain places on the board(s). I'm not a TV guru, so I don't know where voltage needs to be present, but I did follow the power and found some weird breaks after capicitors and resistors.. I keep hearing about something called a congelance power or something like that when reading about these sets, but no real information. Any idea on the cost of repair, or where I can get the parts and do it myself (electrical experience).

Well, the first thing you need to check is....
Are you getting 143 volts to the horizontal output transistor in Standby mode?
If you don't, then you check the transistor for a short....
If it's not shorted, then you replace the power supply output transistor, the caps in the power supply and the Drive IC for the supply's output...
Divide and Conquer....that's the name of the game....
