Got an X-men from a buddy recently that showing errors on the self check boot up screen as pictured below. Was told it was playing without audio but then completely stopped working.
It's obvious the custom board was leaky so I suspected there was some damage to the traces and I ordered a reproduction from Ian Kellogg. The schematics for this PCB are incomplete so I could not determine if all the signals to the unresponsive chips were common to this component but I went ahead and replaced it anyway.
I went with the assembled chip so the Caps were already installed. However the original Konami custom chip and Dac chip will need to be transplanted. Carefully remove them from the old board after you remove it and place them in the correct orientation on the new one.
I'm happy to report that after the chip was soldered into the pcb everything was perfect.
For those interested in socketing the chip its 1.778mm 56 position dual wipe. It will need to be cut in half but will work fine.
