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.
