Oddly behaving K3

Lee J. Imber (WW2DX)
Good Morning All,

Have gained an odd issue this morning. Rig is serial number 464 and  
has been flawless since the day I got it. Last night was on 40M CW  
DXing, all was well.
This morning got into the shack (rig is always left on) and I went to  
change the band from 40m to 20m. I pressed the BAND button and nothing  
happens. I try the MODE button and again nothing happens. I can tune  
the main VFO just fine but then I hit the ANT button and that  
activated Noise Reduction (NR), I press CWT and that toggles CMP/PWR,  
I press RX ANT and that turns on the Noise Blanker, ATU TUNE toggles  
the AGC settings, you get the idea. It seems the button mappings are  
all corrupted.

OK things that I have tried:

1. Power cycled the Rig - no change.
2. I was running FW 3.30 and I downgraded to 2.67 (tried this process  
twice) - no change
3. I then figured it was a hardware issue (loose board) so I tried  
software controlling the rig with K3EZ and still no good, I can't  
change bands via software!
4. I pulled the power plug from the K3 and let it sit then powered  
back on. - no change
5. I then tested my voltage on my power supply (Astron 50Amp) 13.8
6. I have done a reset holding the SHIFT/LO while powering up but in  
my case its the SPOT button that does that function. After a reset  
still no good.

I think I have exhausted all that I can try at this point.

Anyone have any suggestions before I call Elecraft?

Thanks and 73,

Lee
