Hello,
I have a spare working one that I picked up to back mine up, as it is one of my favorites from childhood. I never looked into it, but it plays very dim. in a darkened room, it looks fine. In a well lit room, it is very hard to see. I was told that this is an easy fix, and there was a post on it a while back, but I don't use this machine yet, so I never looked into it. Anyone familiar with this problem, feel free to chime in. I am located in Pittsburgh, PA 15202
