I suppose its worth another look. I pulled the case apart once before, but went no further once I saw that goop. If you can remember, are the pins soldered on the "top side" (cover side) or the "back side" (toward the cast casing)?
It would be a lot easier if I don't have to pull the whole board out of the goop. If I could just dig out enough goop from the front to get in there and work the joints, that would be well worth a morning try.
Pulling the whole thing out to get to the back seems like trouble. Might be easier just to cut an access whole out of the back, if possible.
In my case, I'll have to be careful so as not to damage anything.
