I've got a bunch of Konami System GX boards and I have 2 faulty main boards.
Faulty PCB1: No video output; solid black screen.
This PCB was originally paired to Run and Gun 2 Sub-board which being a dual monitor game uses the SUB board for video output, leaving it with Run and Gun 2 it works perfectly and passes all tests. If I swap to a normal sub board (like say Salamander 2) which relies on the main PCB for video output I get the blank screen.
Faulty PCB2: No Audio output; dead silence.
I'm fairly certain the audio amp is working, if I crank up the audio in the test menu I get a nice amplifier buzz in the speakers... just no game audio. This PCB is a Daisu Kiss, though I don't think that matters. Again this one passes all tests. I haven't tried swapping out the SUB board on this yet, but either way I'd like to get both the main board and the sub-board working.
Anyone know of any System GX repair logs that might lend some insight or has anyone ever fixed any similar problems on these PCBs?
