This was my thinking and why I posed the question about the IO board.... I'd be following the wiring from the JAMMA edge RGBs lines back to the chassis to see if there's a disconnection somewhere.I have a feeling that the Jamma video signal is disconnected. My chassis only ever worked through the VGA cable. I never actually tried 15khz, only 24 and 31khz then it died.
