Well I finally got around to pulling a tube from a tv and using it with the cabinet's neckboard and chassis and was luckily very successful. Unfortunately, The picture appears to be flipped to where the picture is upside-down and even if the tube were turned 180 degrees (thinking i put it in upside down, i tried turning my head and noticed this) the image would be mirrored. Other than that the picture is excellent, so I think its just a setting on the main board?

but i couldn't have a clue. Any ideas?
Also, the game is Mortal Kombat 2 if that helps, and as I said, its a K7000 chassis.
