Well, I haven't gotten around to it yet but I think the socket issue is it. Lately, I have been spending my free time working on some arcade games to sell ASAP. Most have little issues and I am getting around to them and more importantly CLEANING them so I will do a check on the socket. I am pretty sure IF I go to replace U1 I'll just order it. I have some other things I need to order anyways.
Let us know how you went when you have fixed it
