[Elecraft] K2 Front Panel Issue

[KW4H]

Yup, the firmware comes up -- I get the "elecraft" signal in the display
and then the usual 40 meter freq.  After that, the display is frozen with
the frequency display and the buttons do nada.

My best guess is that it's probably something simple like a missed solder
connection (it happens to all of us!), but so far I've not found anything,
and all the boards passed their resistance checks.
