Hello,
I have a dedicated MK3 cabinet that I am having issues with the sounds. I get nothing. Everything else seems to work perfect. This is what I have done so far. I checked all the voltages at the jamma connector. I have +5.09, -5.10, and +12.13. I have checked continuity from the speakers to the jamma connector. When it boots up it runs through the rom tests with no errors and automatically boots to the game when done. I hit the test button and go through the sound board test and nothing is highlighted. I get no sound. I have adjusted the volume on screen to about 3/4 of the way up. I just replaced the sound amp todayTDA7240A and still no sound.
I am at my wits end with this game. Any suggestions where should I go from here. I am only a novice at arcade repair and I might be missing something really stupid.
