Hi

Real solder has lead in it to eliminate tin whiskers.

We're going to see a lot of stuff die in the coming years from these little
critters.

While the heat gun on the Rb lamp is a nice trick, the whiskers most 
likely is nothing but traditional tin whiskers. A bit of re-soldering to 
remove bad metal and replacement of burned transistor is where I would 
start.
