You didn't say you got it working again, but I gather you did. Nice work,
Jim. When it comes to electronics, I'm lost. Only good fortune in my shop
yields a repair once the magic smoke gets out. I don't have a clue how to
trouble shoot the vast majority of devices these days.

Yep, it was working again when I was done. It was actually a pretty
easy diagnosis, as there were *two* parts floating around free inside
the housing, and one of them (the heatsink do-hicky) was a brittle
fracture off its base, so it could only go back on one way!

I felt kinda bad because I didn't take the time to reverse engineer
the schematic for it, but my free morning time was up at that point.

Jim
