Hello Everyone,

I got my boards back from ChrisHibler and my machine is up and running. I have one display that I need to replace and a few bulb issues to fix. My main issue now is that I have no sound at all. The sound board was tested before it left the shop and is working 100%. I’ve tried swapping proms and adjusting the volume but haven’t had any luck in getting any sounds to play. I also checked the fuse and it’s good. Any suggestions on where to start?

Is the speaker OK? Try measuring ohms across the speaker wires - should be about 8 ohms. Do you get any sound by pushing test button on sound board?

So the lowest setting on my multimeter for ohms is 200. I got a 0 reading on the speaker. The board itself doesn’t make any sound does it? I’ve pushed the test button and nothing happens.

Looks like the speaker is shorted. Try another one.

Quoted from jwatkins712:

No, sounds do not come out of the board, since there is no speaker on the board. The board sends sound signals to the speaker. However, to use the test button, the game needs to be in "Game Over" mode. There should be a specific procedure for using the test button described in the manual.

If you're reading 0 ohms at the speaker, the speaker is shorted and needs to be replaced. You should have taken the resistance reading on the speaker itself with the speaker unplugged.

Thanks everyone. I’ve got another speaker on the way. I’ll update here once I have it installed.

So the speaker was bad. I also found that the sound prom I ordered is faulty. Should have a new one in a few days.
