[Elecraft] High SWR no power out

[WR5DC]

    I have a K3 that quit transmitting on SSB last night so I connected an
SWR/Wattmeter/Dummy Load directly to Antenna 1.  I held down the xmit button
and the display reads 16 watts. 99-1  high swr.   I have the optional
antenna tuner but it is in the bypass mode.   I also tried selecting ANT2
with the same results..   Anyone have any ideas before I send it back to the
factory for repair?
