Possibly. Wiggle the connectors while looking at the cavity on a spectrum analyzer and if the peaks and dips change significantly that's probably the problem.
The one I had the solder kinda looked like it was sprayed out of one joint at the top of the can, and there was a lot of flux around the joint.
