[Elecraft] Dead K3

[TMorton]

Hola,
I received my factory built K3/100 #250 in March. I returned it to Aptos 
in June IOT have sub rcvr installed, etc. Recently returned and after 
setting it up, I turned it on to see 14000.00 and HI RFI in the sub rcvr 
window.  There is no sound whatsoever from the rig The B knob is frozen 
in that turning it does nothing. Selecting Menu or Config gives me blank 
in Upper window...
No bueno for contesting or dxing...anybody got any ideas? OH, once I was 
able to get in the freq window (Upper) Mode E 000200 and once saw uC 02.24
Help, pse..
