[Elecraft] Info 201 again

[Tony Morgan]

Hi Guys,
K2 #4049 w/KPA100 + KAT100. Working without any problems for almost a year.
Was running MMTTY @ 25 wts today. After returning to receive K2 locked 
up, no audio not able to do anything. Turned it off and back on and all 
was normal except could not access menu. Turned it off again and left it 
for a couple of hours, turned back on and am getting info 201 then 
ELECRAFT then 7100 plus some hum from speaker.
Where to check first when I open it up?
Thanks guys.
