So my right mini flipper stopped working. It'll flip on the first couple button presses and then goes dead, and occasionally will flip but will never hold. I did the switch and coil tests which seem to be working. I even replaced the coil which didn't fix the issue. I switched the flipper boards and nothing changed. I don't see any fuses out. I really don't know what to check next so I'm hoping you guys can give me some ideas. Thank you
