Hello...I am facing the same exact problem. Did you eventually find the issue with yours? Any help would be greatly appreciated. For a bit of information...game played fine one day and then the flashing “display version”
Update...when I take batteries out, I get back to the screen working but it says open door. When I do that, the door switch is open and the game works fine. This is some crazy stuff. I have to be able to close the coin door to use this. Ughhh. Any ideas?
