Steve,
Maybe a long shot, but try removing U6 (Control Board) from its socket and
plugging it back in again - with power off of course while you do this :-)

The problem has been fixed -- thanks to all for the help.

My best guess is that it's probably something simple like a missed solder
connection (it happens to all
