It's a video file I don't believe totally worked. Anyways.the.game has a ghost effect.with cars on screen. Trying to pjnpoint if its a monitor or game issue.
My guess is that it's a game board issue. Boot the machine up with the test switch on and go to the playfield test. Do you have similar issues on that screen? Does the video still tweak out if the car/playfield isn't moving?
First step....clean and reseat *all* socketed chips. It just may solve the problem. If it doesn't, you just took care of the first thing you do before trying to chase down a problem with the board.
