Colin,
My K2 #3255 shut down one day when about 2-1/2 years old leaving the display
showing the frequency last used, but none of the front panel controls
functioning except the power ON-OFF switch. After an overnight rest all was
well. Eventually I found the problem to be caused by the socket of the
Control Board MCU, perhaps a bit of corrosion, and later I replaced the
socket with a turned pin type for a lasting solution.
73,
