Hadn't played my Shadow in a while, and when I turned it on it seemed to boot OK, but it's not working.
Here's what I have:
GI is on.
Will start a game (without kicking out a ball)
Board indicator LEDs seem correct.
No coils, game or test
No flashers, game or test
No controlled lights, game, test, or attract.
I get a single "bong" during startup, but the mini-playfield paddle does not move.
Things I have treid:
Reseated ribbon cables and power connections to MPU and driver board
All fuses checked with meter
Driver board TPs with meter. 50V is more like 70, everything else really close.
What next? MPU or driver problem?
Any help appreciated. Maybe The Shadow knows........
