[Elecraft] K2:Problem with new build. buttons and encoder don't work

[Larry Naumann]

I am in the process of building a new K2 and have run into a problem

When I do the initial power on testing I get the Elecraft sign then 7.1000
but the encoder 

And all the buttons do not work.

I have checked all my solder joints and the proper placement of parts along
with RP's, all

Looks good.

What should I look for next?
