Hi all,
Could use some advice... I have a Midway Space Invaders that I recently revived, sort of. All was working except 2 sounds. I replaced just about every chip in the circuit(I have the original diagrams) Getting frustrated, I bought a used Daughter board, same number as mine, and tried it. I now have no picture or audio! I get about 1 sec of the screen when I shut it off only. The tube is lit. I tried another power supply that I had(All voltages are correct), cleaned both edge boards, I even tried my ROM test chip. Do you think the daughter board took something out of the main board? I don't know what else I can check. Fuses are good too.Maybe it's time to let the Space Invader Board Guru fix it, eh?? What do you think? Any help would be great. Thanks.
