K3 transmit problem

[K5LAD]

Gurus Wanted --

I'm having a problem with my new K3 and would like
some suggestions if someone has lived through the
same problem.  This is transceiver kit received June
17, 2008 - S.N - 1068

Problem:
Cannot get any transmit power out.

Settings:
KAT3 - Byp
KBPF3 - nor
KIO3 - nor
KNB3 - nor
KPA3 - not installed
KRX3 - not installed
KXV3 - nor
TX INH = off

Receiver is OK and receives on all bands

No error messages displayed on either RX or TX
I can hear weak signal from K3 on other ham
transceiver.
Have 100w. amplifier KPA3 but it is still in the box.
TX LED lights with XMIT button
Displays ANT1 on LCD
Only filter available (2.7) is located in middle (F3)
position but all RX and TX modes are set for F3.

Things tried:
Checked through archives and tried suggestions
other had tried but most of these had an error of
some sort displayed.  The error message helped to
aim the user toward a solution.
Several mentioned corrupt firmware so I upgraded
and downloaded latest firmware last night but still no
transmit.
I've tried at least 2 different coax cables, 2 different
wattmeters, and 2 different dummy loads.
Any of the procedures for alignment which involve
transmitting stop me dead in my tracks with no
output.
I've emailed K3support last night but have, so far,
received no reply.

I've built lots of kits and multiple transmitters but this
one is a little different animal.  If anyone has a
suggestion of something I should check before
disassembling the rig, I'd be grateful.
========================================

Additional unrelated problem noted:
Setting the Date and Time - only first digits will
change with VFO A dial (Month and Hour)
Pressing the buttons 2 and 3 don't let other parts
of the date and time to be set.
========================================

I appreciate any help.
73,
Jim - K5LAD

Hi Jim,

You didn't say that you have run the TX gain setting procedure. If not,
do that first. If there is a problem with the LPA you'll see ERR TXG
message in the VFO B display area.

My K3 had a defective LPA module, which Elecraft quickly replaced once
we determined that power at the input to the module was OK, but no
output was being produced on any band.

Make sure you're not in TEST mode.
