shut down / restart on keying, now no power


 

Hello all,?
?
I have a problem I'm hoping for help with. Three different times last week, my IC-7K shut off when I keyed and then immediately restarted. I've never previously experienced this in the two years I've had the IC-7K, with daily use (99% CW). The third time it shut down/restarted I was in the middle of a traffic net, which I finished after the rig restarted, no problems, and I turned off the rig as always. And then it wouldn't turn back on.
?
I know very little about electronics, and I'd very much appreciate any thoughts.

Many thanks,
73,
