So I have had this Data East Star Wars for quite some time, have gone through a litany of issues over time, but it has gone down to a point of frustration.
To start, it has a Rottendog CPU, I have a Rottendog Power supply but swapped the original in with no change. I tested the voltages for the DMD and the values checked out, DMD Connected with both power supplies. Test points checked out at the Power supply board itself. +5v at the display board checks out as well.
Power Switch ON, Obi Wan Talks, GI's come on with power on, CPU Boots Properly, PIA and 5v light come on, PIA goes out, and Blank comes on, Relay kicks GI's off, Blank and 5v stay on solid, DMD comes on with "Display Version" and information, and just flashes that over and over, no further. I have been checking the voltages and they check out on the CPU and Power supply (rottendog and original).
Picture attached if it helps.
If anyone could point me in the next direction, it would be much appreciated.
