As per title, I was fiddling with the playfield switch connectors on the CPU board with the alphanumeric display face down on the playfield. When I lifted the display to put it back, it was dead. Game works fine except for this. So far I've:
Checked fuse F301 on display driver board - tests good
Checked AC input voltage to display driver board (J307) - reads 88V AC
Checked DC voltage into display driver board (J306) - reads 4.9V DC
Reseated ribbon connector from CPU board
At this point I'm at a loss.
Any help much appreciated!
Cheers,
Steve
