I have a Bally Black and White, i took the top marquee glass out and set it on top of the open door( wire's were connected so i could not set off to the side) to change bulb and starter and i bumped it and it touch one of the reals and now i have 7.2 erreor showing where the credits should be. I tryed the reset button, and also turning it off and waiting a few min, still no go. Any suggestions on how to clear it? Thanks Darrell
