 New firmware should be out in 10 days, that I hope fixes the problem.
 Although I now prefer to keep the screen on 24/7 so it's non issue for me.
 
 Other possibility if you were not using the screen saver mode is that you might have had a voltage sag that locked up the unit. I am not sure if your area is prone to that, if so I suggest either a small UPS just for the controller adapter or you could buy a Fridge Guard for a few bucks.

 That makes sense. Thanks 
 
 
Can't keep the screen on since it is outside the cabinet and in my bedroom. Hopefully they resolve this issue in the next update.
