[Elecraft] [PX3] Does not respond to the knob being rotated

[James Austin]

My PX3 no longer responds to the knob being turned. The only indication I
see when turning it is when the marker frequency is being displayed. When
turning the knob, the displayed marker frequency bounces back and forth
between something like 14.050.80 and 14.050.85.

The PX3 is otherwise functional.

Any suggestions? I opened it up and all the solder connections for the
encoder are solid.
