My Aerocity Cab monitor is vertically mounted and has been working fine. I have a Galaga 88 board in there for a long time now. But, just tonight after playing for about 30 minutes, the screen begins to slowly creep upward. The score display actually begins to crawl out of vision. Then, if I turn off the cab and turn back on, the screen is warped and distorted.
If I wait about 10 minutes and then switch on again, it is fine and then it begins to creep again after a half hour or so.
Any ideas?
