[Elecraft] KPA500 MCU LOAD screen

[VO1HPFrank]

I came in the shack  yesterday and the KPA500 screen was lit with MCU LOAD
message. I did not leave the amp on.  The amp was on when I arrived.  I
updated the firmware to the current release.  This morning the same thing
happened.  When MCU Load message is on the screen none of the front panel
buttons are active including the POWER.  Have to unplug to reset.

What is happening. ?   How can I clear this from happening?
