[Elecraft] K3 Display Won't Shut Off

[Drew AF2Z]

I've had the same effect by setting the K3's Alarm to ON then turning 
off the p/s. When the p/s is turned on again (and maybe the K3 Power 
button pressed; I forget the exact sequence now) the LCD backlight comes 
on. So, you might want to check the Alarm setting.
