Mark,
I think you will find that the socket pins of Front Panel U1 are not
well soldered.

My K2 (S/N 7867) which I built has always had an intermittent problem with
the bottom horizontal row of LCD elements. Often they are missing until I
slap the top of the radio. Then they will come back on for a while. I'd
like a more permanent solution. Looking for some ideas as to where to
focus my investigation. Do I have a short between the front panel and
control board? A loose connection somewhere? Was thinking maybe this has
been seen before and someone else's solution could help point me in the
right direction. I'd like to try to fix it myself before I send it out for
repair. Thanks.
