I had my PC-3 and PC-3a apart recently to fix the power swtiches. They weren't really registering the different positions correctly. While I had it apart, I messed with the LCD on the PC-3a a little bit to see if I could reduce the bleeding issue it has. I failed to fix that but I did take some pics of it all if they help. I didn't see any markings on the LCD which I had completely off the motherboard but I didn't pull it out of the metal housing.
