[Elecraft] K3 #2913 Stuck with MCU L D on the Display

[ANTNEE N3ANT]

Thank you for the reply ! ! !
 
I got a call from Dale....A tech from Elecraft
 
We did some test on the K3 and found out that a chip (U1) on the K103A board
went bad and am sending It back for repair.......
 
It might have been zapped In a lighting storm when I forgot to unhook the K3 ?
 
Thanks again, Antnee N3ANT

Remove K3 power by pulling the power plug. Wait about 30 seconds. Shut down the K3 Utility. Plug the radio back in, and turn it on with the power button. Then start the K3 Utility again and load firmware
