Having the 922 on a surge protector made no difference.  After the unit makes it's update check and goes in to the screen saver / idle screen, it is unusable with just a black screen.  The 922 has to be reset each morning in order to watch TV.  The problem this causes is that I no longer can use the sling if I am away from home longer than a day because someone would have to be there to press the reset button to get everything started each morning.
