[Elecraft] Blank display on K3 power on

[Glenn - N5RN]

All -

I turned on my K3 this afternoon and was greeted by a blank display.  I 
found that I couldn't turn the radio off using the front panel button so 
I pulled the power.  After plugging the power back in, I tried again.   
A blank display.  Since I had a backup I opted to try a reset (shift 
LO-power on) and the radio hangs at the EE INIT display.

Is there anything else I can try to bring the radio back to life?

TIA -
