well i have pulled receiver apart, and have been checking traces with ohm meter. I have traced voltage from ac input all the way to a capacitor right before the relay, i have voltage on 1 side of the cap but nothing on the other side, i checked the cap with a ohm meter also it shows nothing..according to the schematic the power has to come through this cap and relay before going into the fuses...could the c525 cap be causing all this problem
i just found several problems....it looks like lightning must have got this thing, or the guy majorly shorted it out..i checked readings against a good working receiver...found mini trans bad, 1 bad cap, several resistors bad, etc etc...
Boy, I'm really beginning to hate this service manual. Well, you can try subbing in a dc voltage at the 5 volt regulator, and see if the micro responds when you press the power button.
You can sub in 10 volts or so at C522, or if the IC protector is open, you can sub in right there at IC 501.
