Hey all, I am thinking about trying to bring a Star Shooter cocktail back to life. This example has working flippers, gi lights and display but that is about it. The game will not coin up and will not enter diagnostics. Any suggestions on where to start? The boards look good with no corrosion or obvious damage but the lack of diagnostics has me concerned this thing is doa. When powered on it never starts the same way twice including the on board LEDs. Appreciate your thoughts as always.
