Greetings all,

I have a JY machine that was working normally, then one day decided to randomly reboot during play. Troubleshot the problem enough to determine that it's happening when a certain leaf switch is triggered on a standup target in the crane area. When it happens, a sound effect actually plays and then DMD flashes "raindrops" (at least that's what I'm calling it...random diagonal lines evenly spaced across the DMD). Flippers go dead...almost like it's a tilt. Then when ball re-enters the trough, it starts up again. Plays fine until that standup is hit. Any ideas why a leaf switch would cause a game to reboot when it makes contact?

Gotcha. I recently attempted to replace a different switch, which was unsuccessful (in that after I did it the switch still didn't work). My guess is that the diode on that one is going the wrong way. The problem didn't start until I replaced that switch. Seems like a good place to start at least. Thanks, Llyod!
