I picked up a Stern Hot Hand this week. Once a game is coined up, only the flipper solenoids are working. The other solenoids, all three thumpers, the kicker, both slingshots, the outhole, the drop targets, and the motorized bat at the top of the playfield, are all dead. Looking at the schematics, I see that all of the dead solenoids (except the rotating bat) are common to plug J5 on the solenoid driver board. I also see that they are all common to U2 on that same board, except the rotating bat.
I haven’t had a chance to take any voltage readings with a meter. I'll get them this afternoon. For now, if my flippers are working, does that rule out the bridge rectifier board?
Other than connectors and pins, which I will be getting to, can any of you suggest another common area that might contribute to this issue?
