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 :-)
My K2 froze in similar fashion about 2 years after I had built it, and the
cause was poor contact between one or more of U6's pins and
Sounds like a great idea, thanks. I'll give that a try.
If nothing else works, I'm going to have to start doing things the old
fashioned way (scopes and probes), with the final solution of getting
Elecraft on the phone. Looking for the easier solutions first!

Check to be certain all ICs are soldered at all pins, but first check
the orientation of the diodes on the front panel.
The DC voltage chart in the back of the manual may be helpful.

The problem has been fixed -- thanks to all for the help.
I took the front panel assembly apart and discovered a missed solder
joint. Sigh! All's well now!
