Quoted from CaptainNeo:
you sure those jumpers are right for those roms? did you reseat the ribbon cable? Try disconnecting all of the other displays and flip the cable around and try it on just one display. meaning. Use one of the connectors that normally goes to a display, and plug it into the board, and use the next one in line to go to the display. That will tell you if it's a cable issue.
Game was running very well before this event.
I did reseat all the display connections.
There are other issues.
A hum coming from the playfield now. Very mild buzzing.
The game starts with bad displays and a hum.
The game takes credits but wont launch a ball. Another solenoid fires weakly but not the ball kicker.
All of this after grounding out the jumpers i think.
Its possible that the jumpers are not connected properly.
but I dont know what the behavior would be if that is the case.
Something might be wrong with the logic?
