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.

I just checked to make sure that the roms were correct, and they are, also it was working before with these roms.

No buttons change anything, I have gone through and checked them all one by one. That is what makes it so frustrating, because it doesn't make sense theoretically.

Any direction I should go next, or just strip it down and start from scratch, its driving me nuts.

So I went through the voltages again, and they are coming out correct... So I decided to order a matched set of roms ( CPU & DISPLAY ) from Marco Specialties, to make sure they were good. I installed them and it has the same issue as before, so the roms are good. Guess Ill contact RottenDog and see if they have any ideas...

Thank You
