Made a 4 player setup for a friend and when he got it home I think the 4 player adaptor came off and he put it back on and it blew the fuse. I replaced the fuse and got it back up working mostly but now it doesn’t display cga anymore. I have tested and get hdmi and vga video but nothing off the jamma board. Anyway to get it repaired? Thanks for any help.

I'll be happy to repair it if you send it to me in Australia, but I currently have a broken wrist so it may be a few weeks before I can rework boards again... PM or email me if you want to work that out privatly.
I'm happy to talk you through trouble shooting if you can swap out parts yourself. It's likely to be the video amp chip (the only surface mount chip) or the sync combining chip (the largest of the DIP chips).
