Ken,
Since you can see the display - and it seems to be proper, many of the front
panel signals must be correct.
I would look closely at the SR CK signal on the control board and on the
front panel board since this signal is common to the circuits that you
report as failing. Check the connectors on the all 3 boards and U6 pin 35
on the control board. This may or not be the problem signal, but is a good
starting point.
Re-check the soldering carefully (don't forget about the connector pins)and
be certain all the pins of Control Board U6 are properly in the socket (not
bent under or sticking out).
Good luck and bst 73,
Don W3FPR

Am working on putting my secound K2 together, have run
into a bit of a problem,
am on the first light alignment and test, part 1, K2 powers
up, info 201 comes on
(and disapears) then the elecraft and 7100.cc c, everything seems
fine to that point,
but, not a single button will work, the VFO knob will not change
the display, nothin,
up till this point, every check, every resistance check was spot
on, have checked all boards for any unsoldered
joints,bridges,parts placement etc, (using a lighted magnifing
glass,eyes are getting old !)anybody have any ideals as to
where to start to check ??
