Fwd: Mayday K3 no receive no output

[w0mu]

I need some help.  I am down in V31 for the ARRL DX CW contest. Took the
K3 out of the carry on and the receiver is dead.  No signals received on
A/B or rcv in.  The radio did take a fairly hard hit when it was knocked
over in the case at the airport.

I have essentially take the radio apart and reseated everything but the
front panel.

I reloaded all the firm ware.

The radio has the ATU unit, dual receiver Transverter board, new syn board.

TX cal tests failed with 0 watts.

I deoxit the pins etc.

Any ideas or direction?

Both receivers are dead.

Ken,

first-aid idea (as you said both RXs dead and Cal failed...) :

1. Turn ON K3
2. On the K3 front panel, hold CONFIG menu and turn tech mode on (CONFIG: TECH MD ON).
3. Tap MENU to exit the menu and then tap DISP on the K3 front panel.
4. Rotate the VFO B knob to display SYN1 in the VFO B area of the display. You should see the
status OK. The same for SYN2 status OK after...

If there is no OK status of both synths then check the all TMP coax cables from and to the synths boards and check if synths boards seats well in the multi-pins headers...

Z3 board came loose and probably damaged.  Removed and soldered a jumper
re Elecraft support.  We have power.

Nothing on receive yet.  Triple checking on the tmp cables etc as I have
had the radio apart many times.

AGC, pre amp seem to have no effect.  Receive on the xvter board is also
dead.
