[Elecraft] Blank display on 1st power up

[W3FPR - Don Wilhelm]

Roland,

That sounds like the behavior one would see if the control board is not
properly plugged in.

Since you received the kit partially built, you should first gain confidence
in what the previous builder has done.  I suggest that you go through the
steps in the manual (starting at the beginning) and recheck everything -
component values, proper orientation of components, and the soldering of
each component.  I know it is a large task, but is the only way I know to
check things.

Chances are very good that the components are not at fault - the most common
cause of problems is improperly soldered connections, second is incorrect
components (or incorrectly located components).  Actual component failures
are way down on the 'trouble' list - they may fail, but that is rare.

73,
Don W3FPR
