Hey all, I joined the MGOW club a couple of weeks ago with a machine that had been sitting for at least 10 years unused. Got it home, checked fuses which were surprisingly all good and the correct values. Gave it a once over and not seeing anything glaringly obvious that looked out of sorts, I plugged it in and turned it on. The machine coins up, starts a game, a couple of solenoids fire and that’s it. “Prepare for battle” is spoken and lamps are lit but none of the switches and solenoids do anything. I performed the ground mods, cleaned up the connectors and contacts on the boards and still have the same result. Power supply is good and voltages are spot on. Bridge rectifiers in cabinet all test good, Original Orange cabinet capacitor has been replaced. Both Driver and MPU have had repairs done at some point... transistors on the driver and Z2 on the MPU has been socketed and replaced. Not sure where to go from here and am hoping someone can offer some suggestions. Thanks!
