I've had a Robocop board in storage for a while and recently pulled it out to test it. When I turned on the cab, the board made a low beep through the speaker, then static. The screen looks like the sync is off (wavy picture), along with a garbled, scrambled screen of what almost looks like Chinese characters. I've tested it in two different JAMMA cabs, with the same results on each. Has anyone ever encountered errors like this with Data East boards? I have the troubleshooting/schematic manual, but its surprisingly lacking in technical troubleshooting details. I haven't had any luck finding repair logs via Google. Thoughts?
