I'm not the expert here, but quick questions:

1. Any PCB damage? Any cut traces, broken components, bent pins, or bridged traces?
2. Was it working before?
3. Re-seat all the EPROMs.

Can you post clean picture of the PCBs?
 
I see these same lines occasionally on both of my superguns. A quick cleaning of the Jamma edge/connectors and a firm reseat usually clears it up. If you are getting funkiness in two different boards, maybe start there.
 
The board is very clean

Maybe im gonna give it another good cleaning in the jamma edge
 
What setup are you using? From memory I had issues like this with my Boardmaster Control Box? Could also be your video cable if it’s a supergun?
 
Now they have a red running in background in start up with the warning
