[Elecraft] Frozen K2

[Rolf]

    Hi,

    My K2 #4979 has worked fine until now. Suddenly the poor
    thing appears to be dead. When powered on the display first
    shows ELECRAFT then 7100.00 and a constant sound hears.
    It does not respond to any buttons or knobs, except for the
    power knob.

    I believe that a bad extension cord is to blame. But what can I
    do get live in my dear friend again? Anyone who knows?
