[Elecraft] Odd K3 Behavior

[Jay]

I could be the steel connector pins on the front panel 
having some corrosion on them. My early  is back in CA
for retrofit of gold pins for similar stuff.

Subject: [Elecraft] Odd K3 Behavior

My six year old K3 (#217) has been behaving oddly the past few weeks. The NB
button sometimes doesn't work at all, either short press or press-and-hold,
and sometimes when I press and hold it to bring up the LEVEL settings it
behaves as though I'm pressing SPEED/MIC knob -- i.e., the display will
toggle between CW speed and Mic level. Also, the left side of the BAND and
MODE buttons sometimes do nothing when pressed; the right side of these same
buttons continue to work. There may be other similar problems with other
buttons, I can't remember. These are the two that I notice repeatedly since
I change band, mode and NB settings often. Nothing out of the ordinary
triggers this; one minute it works fine, the next it doesn't.

I can sometimes get the rig to behave normally by cycling the power, other
times by pressing another button that does work. Other times nothing works,
until it just starts acting normally by itself. I've reloaded the latest
revision firmware as well as an older revision from 2010 that I had on my
PC. I've also reloaded old and current configuration files. Goofiness
persists.

Could something on the front panel PCB have gone awry on me? I have a KPA500
and a PC connected to the rig, if that is relevant. I've not tried to
duplicate the trouble with everything disconnected yet. 

Any ideas?
