To me it looks like video gnd is missing - common on many jamma bootleg pcb (check connection between gnd pin (1,2,27,28) and video gnd pin (14) on the pcb)

Pin 14 is grounded.
Now I'm gonna make a wire between Pin 14 and 1/2.
Edit : by grounding this no fix... still same problem
Any help??

Anybody can help me?
In gonna connect it at My personal cabinet and watch if works correctly. Maybe there is a gnd problem on my home made supergun.

Have you tried adjusting the sync on your cab or the TV?

Re: Gholus and Ghost Bootleg No sync Sync
Many CPS1 bootlegs have a weak SYNC signal, read this repair log for a possible solution:
