I would first check the three power supplies and the fuse M1 when removed.

Okay, so diodes x1-x3 were removed from the circuit, tested fine, and reinstalled. M1 was also removed, checked good, and reinstalled. Still no life.
I'm looking at removing R119 and doing a continuity check across it next. This has to be early in the line. Where would you all recommend I measure next? I have the cord out of the cabinet and I'm ready to take voltage measurements.

Are the 3 power supply (labeled source voltages) in spec?

I'm going to assume no on at least one of them. I'll plan to check them either tonight or tomorrow, depending on my schedule. I think I may also take a look at C1 again, just to see if it's got any amps going across it.

Just check for AC ( to GND) on both sides of C1. If there check the
supplies # 1, 2, & 3 for DC. Keep in mind most the time things in Sams flow left to right. Try to find a mid point & test voltage. Go upstream or downstream from there. 73 Zeno ![]() LFOD ! |

Is C1 AC? I've been checking on the DC setting.

Yeah, I'm thinking C1 is DC because of where it is in relation to the diodes, but please correct me if that's wrong.
