I appreciate the info fellas. I'm an electrical engineer so troubleshooting
electronics doesn't scare me, though I've never opened up one of these.

Robert's right. It's probably moisture on the contact points of the
display. You can try to open the front panel of the radio, carefully
remove the display (which looks like a piece of glass), and clean the
contact points.

This is not an uncommon problem. Often times its just moisture. In any
case the display can be replaced for a resonable cost. Any twobit
avionics shop on the field can do the job in an hour. That's the great
thing about King radios, you don't need to send them back to the
factory.
