MS Pacman video issues

[redfield0009]

I bought a MS Pacman Jamma board of ebay and I tested it out for the first time yesterday. I tried it in both of my cabs and the screen is heavily distorted. All my other jamma boards work just fine. Is anyone failure with this issue?

you need a pot on your sync line

+1 for sync

Thanks for the info guys.

I don't have the time to add a sync pot so I'll just return it and get a 60 in 1.
