Also how is the resoldering job? I'm not the greatest at soldering and would hate to make it worse . I take it I would have to remove the old solder and replace with new?
What you're describing is classically a solder issue. If a joint is cracked moving it will cause it to have electrical conductivity again resulting in what you see.

It isn't hard to do but it also isn't remotely hard to screw up.
