I recently purchased a Battle of Vader Pachinko machine, and although the TIE fighter will occasionally spin (very slowly) the arms holding it won't move so it is constantly blocking the screen. Also, the small screen down and to the left of the TIE fighter won't move down so it is also blocking part of the screen. Does anyone have any idea what could be preventing the machine from moving these parts the way they should move? The LCD on the back of the machine shows the number 7, is that an error code? Any help would be greatly appreciated. The rest of the game is working but it's not as fun when you can't see most of the screen!
