I have a question for you, maybe you know the answer. I have a pacman machine that I got and it is not working. I got a new board that is known to be working so I have ruled that out. I have tested the speaker and that is good. The monitor turns on but displays nothing. Almost like the machine turns on but doesn’t start up. I have tested all of the power leads that I could think of and they are all supplying the correct voltages. I checked online for a schematic and made sure that the wires in the wiring harness were correct. It is still giving me the same problem. I can power it on and the monitor turns on but nothing happens. There is one wire that looks like it is coming from the coin door that was cut. It looks to be white and brown or white and green. Any ideas?
