This this how I fixed it.

The battery was removed and another soldered in.  No charge, no display. Bummer.  Examination of the board revealed that the charge controller chip was missing a leg. Arrgg.  Rum didn't solve the problem.  What to do?

I was able to scrape enough of the chip package away (the chip being 0.8mm pin pitch and about 4mm x 3mm), to expose some shiny copper.  Using the finest wire and a  small soldering iron tip I was able to reconnect the chip to the board.  A re-charge with the new battery re-animated the badge.

Pix to follow. :)

So a new lung and a new, liver?
