Can I test the voltages with the TV off? I have no power or lights to the TV and I'm not getting any voltage readings from the power supply board. Is there a possibility this could be a main board issue also?
If you have no power at all out of the power supply board, then either the incoming fuse is blown or the power supply board is toast. Part of the board has to be powered all the time waiting for a signal from the on button from the TV or remote. Remember check for AC and DC voltages at the appropriate places because if you check with the wrong setting on your multimeter you'll get 0 volts.
BE CAREFUL WITH THIS BOARD AS THERE ARE HAZARDOUS VOLTAGES EVEN WHEN THE TV IS UNPLUGGED!!!! (and even if it's not working! The capacitors can hold a high voltage charge for weeks!)
