I recently acquired a Charlies Angels solid state. When I first got it, it would boot up but not start a game. I re-pinned connectors A1-J7 and A1-J6 on the CPU, cleaned and re-flowed all the contact pads and did the ground mods for all 3 boards. The game then worked. I was playing for about 5 minutes and testing all the switches and coils. Everything seemed to be working but it started making some strange noise from the speaker so I shut it down. I unplugged everything and started over again with the www.pinrepair.com system 1 guide.
All the fuses check out fine and are the right amperage. The bridge rectifiers also check out fine.
When testing the input voltages at the power supply connector I have the 11.5v and 14v but the 69v is reading 0v.
I'm missing the +4 and +8 volts at the A2-J3 output.
+5v and -12v output to CPU are perfect.
What would cause the missing 69v AC at the power supply input?
