Before calling Elecraft, you could try pulling the synthesizer, check 
that nothing could be shorting to the shield and then reinstalling it.

After I installed my KRX3, my original synthesizer was giving me similar 
error codes. In an act of wild desperation, I pulled it and plugged it 
back in, adding two washers (one left and one right, if I remember 
correctly) so that it was tad further away from the shielding. Since 
then I have not had any more problems.

I assume that it was moved a tiny bit closer to the shielding while I 
installed the KRX3, bringing it close enough to make contact. The two 
washers I added were in the installation manual for the KRX3's VFO but 
not in my (early) construction manual for the basic K3 (#67).

Hope this helps.
