I bought a Revenge From Mars yesterday. It played fine for a couple games, then would randomly freeze up then it would not boot back up until it sat awhile. Today I have nothing. The red light on the CPU is on and so is the monitor but the screen is just grey. Won't boot up or load anything just sits there. No playfield lights or anything. I reseated all connectors and ram, changed the CR2032 battery and reseated the prizm board. Right now I have a $3700 paperweight. Please help!
