Excellent. It's always nice to have a second opinion.

Playing with the machine some more last night, the power off pin is
definitely being set low, so it looks like it is the servo chip that's
broken. I now have one on order (I'm amazed they are still available).
All that's left is to hope I can remember how to use a soldering iron!
