K3 no display & flashing LEDS

[Bob Towers-2]

This has probably been anwered already, but I haven't (yet) found the
answer on the forum.

I took my K2 and K3 to the radio club two weeks ago to help illustrate
a talk I did on Elecraft. I didn't power either up, but afterwards I
powered the K3 up when I got back to the shack and there was no display
and the 4 sets of lEDs underneath the display flashed on and off until
I powered it off. My K2 was unaffected by its trip to the club, by the
way.

Help would be much appreciated!

Bob,

I have not seen any replies on the reflector, however I would suggest
that your first attempt would be to remove the Front Panel assembly and
plug it back in.  If you have the tinned FP connector pins, plan on
replacing them with the gold pins in the near future.

The removal and replacement action will remove oxidation from the pin
contact points.

If you moved the K3 from a conditioned area to a cold transportation
vehicle, that could cause problems especially if you have the tinned
connector pins.

If you have the tin plated pins, contact [hidden email] and ask
for the replacement gold pins.

If you have the gold plated pins and the remove/replace action does not
fix things, you can try doing an EEINIT and then load a good saved
configuration file.  If that does not fix it, contact
[hidden email] for additional assistance.

Don

Many thanks for your detailed advice. I'll have a go after Christmas - it's pretty hectic here right now. My K2 will keep me on the air in the meantime!
