Hi Folks!
I did my CPS3 Digital AV install this weekend - and have run into some issues.
The first time I got everything installed and fired up - the video came up and worked great - but for some reason, zero audio on the HDMI (but I did have it out the JAMMA edge). I was trying to troubleshoot this and have made the issue a bit worse.
I assume audio is carried via the BCK/WS/DAT pins? I test continuity for each of those on the helpper board all the way through to the top board - no issues. For the small coax snap in on the helper board - I have the shielding wire going to the ground (which continuity tests out to the ground on the JAMMA edge) and the inner cable going to BCK. WS and DAT come from the small board beneath with the two enameled wires - these also continuity test out to the motherboard.
In troubleshooting I removed the C2 wire to check things, and when I soldered C2 back up - the system wouldn't boot up at all. If I remove the C2 wire from the digital board, it all boots up fine. I tried using another wire on C2 - also didn't work. Keep in mind - C2 was working FINE before - I had video and everything, just no audio. all I did was desolder C2 and them put it back on the pad on the digital AV board. I tested all the pads on the digital AV board to ensure that I have no shorts - and nothing that I can find.
I have the 3 solder pads joined by U11 as well.
Any help would be appreciated! Kind of beating my head against the wall on this one.
