I have a panasonic in for repair. You have to push the power button several times in order the get the relay to click. When it does I hear a high pitch from the power supply and then nothing. I get no HV from the flyback even for a second> I hooked up my HV probe and get no action at all.. It acts like shut down but I do not think so. I did find an open 10 ohm resistor near the flyback but didn't make a difference. I'm waitng for a schematic but haven't got one yet..Any help on this? Thanks

Check for shorted Horizontal Output Q551. Is probably is!
That open 10 ohm resistor is a sure sign of a classic PC failure for that model. See these tips and I will also send you the schematic via

Look for an email from them with a link to download.

Replace HOT Replace 10ohm Replace the Pin Transistor Replace the Flyback. Replace the RH3F diode if there is one to left of flyback. Then you are good to go...

Thanks to all that responded.. I'll check them tomorrow.
