No RF power out of the flex 6300

I was working some stations and suddenly no RF power out of my flex 6300.  No settings were changed.  The RF meter in smart SDR and on my external power meter both show 0 power even when the smart SDR is set to 100 watts.  
I have included a screenshot of my smart SDR settings into a dummy load.  I checked the DAX and all of the little buttons but nothing.  I checked all bands and all modes.  Hopefully I am just overlooking something.

I would try a factory reset . Make sure you export profiles to the pc before doing the reset so u dont lose them

It looks like you are transmitting on antenna number 2, is that correct? If not, you could be transmitting into an open load.

Hey Bill.  thanks for the quick reply.  At that screen shot I was trying antenna two which goes to a wire but I have an inline dummy load that I had turned on.  but it does the same (No power out) on antenna 1 which is the beam or antenna 2 which is a wire or into a dummy load..

OK Scott, I was just hoping it was something that simple. I guess the reset is the best shot,

I did the factory reset and I am getting the same result.  Unfortunately, no output power.

What happens if you change your Global profile?

it looks like changes were made to the one you have as the * indicates changes to your Wx4SKY global profile. try changing profiles and see if you have output

No joy. Changed global profilea, mic profiles, tried deafault and ssb profiles. I cant get it to send out a single watt of power. Tried transmit into anyennas, dummynloads, through watt meters, etc.
When it failed i was running about 20 watts into an amp. Putting out about 500 watts on a 1Kw amp. I happened to be looking at the amp and saw the wattage needle jump up and down once or twice and then go flat to 0. Then, no power since that point.
Of course i have bypassed the amp at this point and still nothing..

Sounds like it is time for that radio to take a trip back to the mother ship

Just an update for anyone following the thread. Tim at flex contacted me early this morning via email and had me do some diagnostics using flex stack. Determined it was probably a hardware issue and had me send it back to TX. Bad news is 4 to 6 weeks for repair...ouch. so i will be on the HF disabled list for the NAQP and other upcoming events.

Bill was correct. Flex received my radio yesterday and today they emailed that repair was done and it will be coming home..less than 24 hour turnaround. .blown Q5 and Q6. Not sure what that is or why they blew but, back in good shape. A+ CUSTOMER SERVICE.
