hi steve, might be a good idear to test all those caps in the power supply, if you can esr meter would better, also test the fuse on the tcon board.

at the top of the tv there will be a lead going from the main board to the top of the tv, the board will be under a metal plate, have you got a meter with capacitance test on it that would be ok, desolder the caps test them out of circuit one by one stick your meter probes a cross the 2 legs to discharge them, then test have fun
