So I've decided to install a 60 in 1 into a non jamma cab. Original cab had a bootleg ms pacman. My problem is that I get strong vertical black lines throughout the games . What I have ruled out monitor, power supply, 60 in 1 board. I believe I have the rgb wires correctly. RGB and ground wired to the rgb ground on the 6 position part and the sync is on the negative side v and have is jumped.
Things I have tried; field ground jumped to common on ps. Common tied to the frame of the monitor. Even if I put another jamma board in it shows the same lines .
