I just picked up a Demo Man and am having an issue with the display. I have tested the DMD itself, and it works no problem. When I turn the machine on it will make the sound as if it is booting, but will not allow a game to start. When I press exit on the coin door after start up it will go into attract mode, but still the display remains blank. Once I get to this point I can add credits, start a game, and it plays with no issues. Any help is greatly appreciated.

Quoted from PinsideTroll:

have you tried pressing on the asic chip on mpu to make sure its seated?

Yes, it is seated. As of now the only thing that isn't working properly is the DMD, and as I mentioned before I did test it in another game. Ribbon cables also appear to be fine.

Did some snooping and this is what I found, though I don’t have a schematic for the board. No fuses out. Do these resistors manage the DMD?
