Welcome to Fabulous Las Vegas
I have this unit that has no sound. Since I don't have any schematics I am not sure of the power requirements needed at the board. I have re-seated all the ROMS and connectors but still no sound. When I originally got it, it wouldn't go into reset. I opened the power supply and found the two pin connector had been pulled off the pcb. I was able to reset it. It plays fine. The game has some light issues too. Since the pcb is a sound/light combo pcb, I figure that its either a pwr issue or board issue. I have measured 14v at one of the connectors but not sure if I should have more. I haven't used my logic probe yet to see the states of the ROMS. I did find the volume switch on the board but it doesn't make a difference. I do get the "pop" when I first turn the unit on but nothing else. I'll attach some pics. In the pics you'll see I am also missing the light pcb on the left side of the door. Not sure if that has anything to do with my sound issue. I've seen crazy things over the years. A liitle about me. I had a Amusements business years ago and now I'm retired. Thanks in advance. Paul
I tried to upload my pics but failed.
