I'm trying to fix a Gottlieb Genie for a friend and I'm beating my brains out. The lower right flipper and the upper right flipper won't activate. I've put new diodes on the coils and replaced the bridge rectifier for the solenoids, but no luck. It has a new-ish MPU and driver board, so I'm fairly confident the problem isn't there. Does anyone know what I should check next? Thanks!
