[Elecraft] FOLLOW UP: K3 Power problem: won't shut down and blank screen on power on

[Ken Nicely]

I had this same issue about a week ago.  I did call Electraft and they
asked me to remove the cover and check some voltages.   I knew the problem
had started when I was messing around with the rs232 connections, so I
thought I would undo the changes before I started working on the radio.

I think in my case it was a bad usb to rs232 converter because once I
eliminated the second connection to the amp the issue disappeared.  I have
not had time to try a different converter yet.
