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).

Video here if it helps.

If anyone could point me in the next direction, it would be much appreciated.

The game does not go past the point in the video. It will not play a game. Everything freezes and the DMD just Flashes. It gets to the point on the cpu of the 5v and blanking going solid but wont move. I will check that connector for sure as well.

Yes it was working, though it has been some time. It has been climate controlled and in my home for quite some time. It went on the back burner because it was driving me insane, and we started fostering. So for a couple years it has sat, now that we have adopted the kiddos we were fostering, I broke it back out and hit it with fresh eyes. It is doing exactly what it was when I put it to sleep. The pinball gods did not touch it... lol...

I went through the voltages, they were all on the high side of spec, except for one of the -100 on the power supply which is -131, -12 is -16.2, 68v is 77.9, 18 is 20 which is close. All the voltages are on the high side of the voltage parameters they are to live within, or lower for the negative ones. I checked that connector on the DMD and it is good with nice continuity, but I will still order a new trifurcon either way. I need some in bulk anyway as I have a couple other machines that need connectors replaced too. But I dont believe that is it as in testing it is sending 5.2 through the board.

I will check through all the voltages again when I get back to it tomorrow.

So, I am back at it. I went through the voltages. Board test points, connectors and such. It is a Rottendog Power Supply btw... Voltages again look on the high side of good, but would almost make sense as the power supply is not an oem that is worn out. I do not have a good known game right now to put the boards in, so we are looking at a bench test. I have it on the bench, have powered it up and it boots from PIA to solid +5 and solid Blanking. To my understanding, this is the correct start up sequence. It stalls immediately after that, but, I did notice that the 6808 micro migrated from the oem board to the Rottendog was quite hot on the left side a quarter of the way in. This could be pointing at an issue for sure. The board it came from had a substantial amount of cancer, but it looked as though with some remediation, the chip was good. I have ordered a 6808 and feel that there is no sense moving forward until it has been replaced.

Lol, I agree. Its odd though, the 5 volt is getting to the display driver... Has anyone else ever heard of the 6808 causing a loop?
