Im in the same boat. My Jam was having issues and I took it apart to clean it and check cables to see if they were loose. I found evidence that it had something leak into it from the display area. And there are/were rusted spots on the chassis and sa few spots on some of the boards. I did take it apart to clean it thoroughly. I got it clean but must have gotten some of the fluid behind the display, I could see a pool of fluid behind it. So now Im redoing the cleaning and focusing on the display its self.
More later.
