My K2, s/n 6301, has been built and operating for several months.  However, I recently relocated and just now was able to put up a long wire antenna.  It is connected directly to my K2 with a KAF2 installed.  I was able to tune it on all bands the radio operated fine for about an hour.  Then I decided to retune a band and the antenna tuner went through its routine, ie. heard all clicks and watched display count down and it suddenly froze up.  The only way to reset was by turning radio off and then on, again.  All appeared normal but when I went to change something using the menu button, I discovered that it no longer worked.  

The menu would not come up.  But the radio was receiving properly, switched bands properly, the vfo worked properly, switched antennas properly and all filters work properly.  The radio is a QRP, CW only.  Any ideas of what to look for?  I will look for cold solder joints although that has been done previously.  Are there any tests that I can perform using only my multimeter and the radio itself?  Should I contact Elecraft about their repair service, unit is under warranty?

Thanks for any help you can give.  I am alone in Albuquerque, NM and my Elmer is in Alabama.  Should anyone on the Reflector be out here, I would love the company.
