[Elecraft] Need help with test stage one power up problems on K2

[Jess Gypin]

Quick update. I checked the 4 MHZ oscillator and it is working. On the
control board that is. Still no joy. I also unseated, reseated all of the
socketed chips and checked for bent, misaligned pins. Socketed chips are as
they should be. Also at the suggestion of another, checked to make sure the
"lock" was not engaged. Still no joy.

Hi all,

So far I thought I was doing great. Just to save some time I thought I would
ask the collective before I go digging for misplaced components and solder
bridges.

I am building a K2 for a friend. I am at the first point of power up
testing. Control board, front panel and a few components on the RF board. I
got the INFO 201 for about 10 seconds, then the display flashed Elecraft and
then 7100.00 as it should. Now the problem. No front panel function. At all.
No buttons work and the frequency will not change via the encoder. Also one
in 5 power ups the LED display will light all segments and the backlight on
the display will come on, but that is all. I have done a good visual and see
no components unsoldered or shorts. I am extremely careful when building and
usually don't have any problems when building. Maybe it is just my turn. Any
and all suggestions would be appreciated. I am thinking firmware perhaps.
