Have you tried to reload the firmware? Sounds as though a bit or two
is out of place. Use the KPA500 Utility to accomplish this.

Ken,
I have the same amp but have not experienced the problem you describe.
When issues like this occur it is best to isolate the suspect device to
minimize the variables.
Before doing anything have you tried turning off the power switch on the
rear of the amp? Wait 10 seconds then turn the switch to ON. Press the
front panel power ON button and check the panel buttons.
If that doesn't correct the issue then disconnect every cable from the amp
except the power cord and antenna. Connect the amp to a dummy load. Turn
off the power switch on the rear of the amp. Wait 10 seconds then turn the
switch to ON. Press the front panel power ON button and check the
panel buttons.
If that fails to correct the problem you probably need Elecraft support.
Keep the group posted.

Hi guys
While I'm waiting for Elecraft support to come forward with a suggestion,
I thought I'd share my KPA500 (sn 0212) Amp's fault to see if it rings any
new year bells with anyone...hi
Just be4 Xmas I started getting an occasional fault whereby the Standby
switch would lock up, then after a few minutes another press of STBY and it
would go Green.
However now it's locked on STBY and won't budge plus all the other press
switches are locked out too like EDIT etc.
Other strange things are happening too, pressing tapping EDIT changes the
band in the Amp.
In 2019, I installed the USB kit into my K3, previous to this I've fully
upgraded the K3 to full spec.
When the K3 and Amp are both turned on the Amp senses the K3's current
band setting, but everything on the Amp is locked up.
Appreciate any info or suggestions chaps!
HNY

Ken.. G0ORH - K3 full K line plus K2.
