So, I just finished a total restoration and all is great and played it many times in the garage. I finally moved it in the house - very very carefully with no bumps. Now it will not play. Everything starts and looks good but you cannot start a game. It did say "short row 5 wht-grn" but stopped displaying that in test now. Still cannot start a game. Set on free play and tried credits but canon start the game. Only thing that is different is that I lowered the back box when moving it. Any assistance is greatly appreciated.
