Mike, In addition to checking soldering joints, double check carefully components on the board with the manual. Yeah, I know, it's a pain but the only thing you can do. Also check the battery plug on the board. I had a problem with the type of wire they chose, as it would break easily if you took it in and out of the case too much.
