Another MIT-er. Well the only way I have handled them is with a small torch.
Clamp the unit. Heat the solder and it will flow down to the low point and
tend to drip out.
Stick a small xacto knife in to break any remaining solder loose.
Not super pretty but all of it can be cleaned up usually and then
re-soldered.
Hey its dead whats to loose?
