I bought a project Freddy. It powers up, I played the last credit, flippers did nothing. Everything else seemed to be working. I think there may be a coil locked on, that's (maybe?) a different problem. I can get into test mode, but the flipper buttons do nothing so I can't navigate. I can no longer start a game because there are no credits. What I've done so far..
Checked every fuse I could find
Cleaned the switches
Bought the manual
Tried swapping flipper board
Any ideas?
