Hey folks, has anyone seen this problem before? The graphics appear to be missing EVERY OTHER vertical line. However this does not seem to affect ALL graphics as MR DO himself, the cherries, and some title sprites are completely unaffected.

I found that the monitor is not the problem at all, because i plugged the video feed from capcom bowling next to it and looked great. The fact that ONLY backgrounds and some sprites/font is affected leads me to think its the game board. is this ever a common problem?? do caps on game boards ever need replaced?
