mathewbeall.Hi Folks,
I got this installed on my CPS3 about a week ago – and when I first fired everything up, I had perfect video – but for some reason, no audio at all.
Since I have been troubleshooting this – the problem has gone from kind of working to not at all, and I just retried soldering everyhing from scratch and got the same behaviour.
If C2 and HS are connected – the game won’t boot and nothing comes out the JAMMA edge (no signal lock from my OSSC).
If I disconnect only these 2 wires, then everything boots up like normal and I get video/audio like expected out the JAMMA edge.
I also noticed that the HS and C2 pad *appear* to have continuity to GND, even with nothing plugged in, but am not sure if that is expected behaviour.
Any help would be appreciated!
Thanks,
Matt
Can you link to some photos of your installation?
Hi BuckoA51,
I posted over here and have some pictures.

Since then – after talking to marqs i replaced U9 and U16 (HS and C2 shouldn’t be going to GND). After that change, the system would boot up – but still no HDMI out on the board, so I am guessing I somehow messed up or blew some chips out. I have since ordered a new board and will try again with a new board.

Please let us know how you get on.
The new board worked perfectly – I am guessing that somehow i managed to blow or mess up the board I was originally using. Everything is good now! My wallet is just a little thinner due to my mistake!
