Quoted from imagamejunky:
An update for you guys.
I mentioned that the backbox screen and the phone screen went completely black. This happened a second time now. This time during attract mode. I’m assuming they are powered off. I will call JJP tomorrow. I’ve read others talk about the phone going blank, but not the backbox screen too.
I will report back.
I just got my game NIB and had the backbox display and phone going blank once. Let me know what you find.
