Its obviously a graphics interface problem. The fact that the display is flipped means its probably designed for one of those cabinets with the screen on the bottom and viewed through a mirror.

Could it be a missing power supply rail, or some other signal provided by another board or module in the cabinet, that isn't needed by the board that works fine, but is needed by the other board?
