[Elecraft] K3 no display & flashing LEDS

[Don Wilhelm]

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 support at elecraft.com 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 
support at elecraft.com for additional assistance.

73,
Don W3FPR
