I am currently having the exact same issues with the Data East LAH that I am working on. Does anyone have any ideas as to the issues here. This MPU board has recently had board work done by a respected professional. I also currently have no picture on the DMD. It is getting all proper voltages at the power input of the DMD.

I will post a video tomorrow in the morning.

The game boots from what I can tell properly now but I have issues with the DMD screen. It comes up for a moment and displays the display version and then it disappears. Nothing is on the screen after that. It is getting the correct voltages at the DMD.

When I push on the IC at D5 it resets the game repeatedly and the PIA LED and the blanking LED on the MPU board go back and forth. All of the lights on the playfield also toggle on and off.

The 6264 at D5 got really hot and I am assuming that it is toast. I was geting -14Volts at the power supply board test point(-12v) and 10.2 at the (+12volt) test point. The 5v test point at the psb was giving me 4.92 but only 4.78 on the MPU test point. Are these normal numbers to be seeing?
