Pete,
Display problems like that are often caused by partially soldered
connections to the LCD.
The pins barely protrude through the circuit board holes and it is easy to
get the solder to fill the hole without heating the LCD pin adequately for
solder to properly adhere to the pin.
I would suggest you re-solder the LCD pins from the top side of the board,
making certain that the solder flows on the pin as well as the PC board.
To repeat -- first check soldering, then re-check soldering, and when you
have finished, check the soldering!!! (that fixes most problems).

I wonder if anyone has come up with a similar happening on the first
alignment (Panel, control board and partial main board) I had
intermitant problems when I first put it together, so I dismantled it
and checked for bad joints, component values, etc. I found I had not
soldered a switch. That put right I put it all back together again. And
it almost worked. DISPLAY did not bring up the voltage/current values.
Tapping menu several times brings up a menu but its behavior is must
odd. Tapping menu again returns to the band and tuning is OK for a few
seconds, rate also works.....then up comes menu all on its own. Lots of
garbled numbers on the display looks like its switching between menu and
band very rapidly. I have no messages, Elecraft comes up OK then this
happens. I've had it apart several times looking for problems, but I'm
darned if I can see any. could a component failure cause this wierd
behavior?
Any help would be most appreciated, 73,
