Major problem. Thought I'd post here before contacting JJP. A few days ago, I noticed that when the pin was turned on (not being played), the machine would shut down on its own (yes with the power switch on). Figured maybe a short somewhere. Lifted the playfield looking for any disconnected wires, but found nothing. Waited a couple of minutes powered it back on, and all seemed well. Played a game, no issues. Walked away and noticed about 5 minutes later, same thing, pin had no lights, nothing on the display etc etc. Turned the switch off. Tried turning it back on. When I turn it on, the light in the backbox flashes on for a second, then nothing. I'm thinking maybe a blown motherboard??
