Have a busted 48 in 1 jamma board. Original snow bros game works fine, but when I plug the jamma board in the display is screwed. Processing works, I can play games blind. The image is grainy, slanted, incomplete and spinning. I hate to throw the board out, can I repair it or get it fixed or am I better off to buy a new one? Damma jamma. Thanks for the help.
 
Maybe. Without knowing such things as:

- what monitor you're using
- what the dip switch settings are at
- how the sync to the monitor is connected
- what voltages are going to the game pcb

...I really can't answer that definitively...
 
Need a pic.

It could be a monitor issue or a board issue.

The sync signal to the JAMMA edge comes from a tiny surface mount 74LV or LXT245 chip that is under the plastic cover of the board.
