[Elecraft] [P3] P3 woes - internal display inop

[Dave New, N8SBE]

Thanks Alan,

I'll take a look-see this weekend and see if it's something I can 
tackle.

I've recently dealt with tiny flex connectors like that on another 
project,
and it survived. :-)

I'll be sure to come back here and report my findings.
