Hadn't played my Shadow in a while, and it turned on but didn't play last night.
Here's what I have:
GI is on.
Will start a game (without kicking out a ball)
Flippers work.
Sound works.
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:
Factory reset
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........
