No power on HF, but transverter still works

My Flex 6300 has suddenly stopped transmitting on my HF antenna port. If I press tune, I don't see any power output, in SmartSDR or on my external meter. Transmitting doesn't seem to do anything either.

However, if I switch to the transverter side I do see power out on the transverter's display, and can hit a local repeater.

This just suddenly started while I was using the radio. I tried powering off and on again, but no luck.

Does anyone know what might be causing this? Thanks!

    Well another gent here had a similar problem and ended up having to replace the finals.

    Before going that far how about the following:

    1) Try switching antenna ports, IE move your antenna to 2 and try transmit on 2

    2) Do you have the ATU?  If so try disabling it and reenabling it.

    3) Are you sure you are in band? There are interlocks that prohibit out of band transmit.

    4) Lastly try a factory reset.

    If none of that works and other suggestions then a call to Flex is in order.

    There is a transmit inhibit option in the setup menu, make sure that it is not selected.

    As I was tinkering with it this morning I ended up shutting down my station power supply power completely, and on reapplying power the Flex started seems to be transmitting!

    Maybe something was just a bit wonky and totally cutting power reset it.

    With any of the many software package out there you can see the voltage the radio is receiving. DDUtil, FRStack, etc... all of them have the feature. Which, by the way, I truly think should be part of SmartSDR. (in a future revision?)
