[Elecraft] K3 RX broken :-( ... where to look at first?

[Oliver Dröse]

Hi,

just setting up for WWDX SSB and probably due to too much RF around 
(HIGH RFI indication shortly on the display) my K3 main RX died. Seems 
the 2nd RX is still operational, at least I can hear signals when 
switching to AUX antenna which is wired from ATU to sub-RX if I remember 
correctly.

Any hint?

Seem to remember there were similar cases in the past where a protection 
diode died which was not on the main board but somewhere else?

Thanks,
