Hello! Your set needs the board that has the microprocessor on it. It is called the "process pcb" and is located on the left side as you look into the back of your unit {with the back cover off, of course!). It stands straight up and is plugged into the signal (or "tuner"pcb). They cost about $100 and are available from tritronicsinc.com. All you have to do is unplug the board from the connector by pulling it straight up. Then you just plug the new board in. Make sure it seats properly. The board is approximately 4" by 4" square. VERY easy repair...you can do it and save BIG $. Just make sure you do it when the ac is unplugged!!! Good luck!!!

fishindad85,

More than likely you have bad electrolytic capacitors in the power supply. I have a tip at http://www.fixya.com/support/r6396176-projection_tv_troubleshooting which should help you isolate the problem as well as tell you where to get the parts. I also have a tip at http://www.fixya.com/support/r9091471-soldering_101 which will help with any soldering issues and I also have a tip at http://www.fixya.com/support/r6981868-replace_circuit_board_in_modern_tvs which will help with replacing any boards that are bad.

Thanks for using FixYa and for the great rating.

Convergence ICs or the resistors powering them are bad. Check for open resistors near the ICs if any are open, change both ICs and the resistors.

Rear projection


Considering that in both cases, the set will turn on but not stay on, indicates either a condition of overheating due to a failed fan or it could be a component going into thermal runaway in the power supply itself that is causing the fault.

This is not a safe area to probe around in since there are capacitors that may contain a charge for a fairly long time.

If the fan cannot be heard, this is probably a cheap repair, otherwise, get an estimate first.
