Donkey Kong Cocktail Arcade Game Video Problem

This video has been uploaded to illustrate a problem I'm having with my arcade. It is not entertaining in any way, and will be quite boring to any not interested in repairing classic arcade machines. I am currently trying to fix the problem, and will update the description if I can resolve the issue. The video noise around the girders is not present in the original game, it's just a side effect of youtube's crappy compression.
