Guys

I have an old cab that when i turn it on the screen works but nothing comes up. There is a plug with 5 wires from the chassis to the jamma harness, i assume its to transfere the image from the pcb tp the monitor. I looked up jamma wiring and its says a cable needs to go to No14 on the harness, there is no wire in No14. Got me stuffed, (maybe its a different harness ??)

Any help guys would be great. Thanks

A pic would be very helpful.

What game is in the cab ? How many pins ?

If JAMMA, 14 is video ground and is required. If you have 5 video wires coming from the harness, what pins ARE they coming from ?

Cheers
