I've had my Mini for less than a month and about two days ago noticed that I could not get passed the "Start up" screen. I've tried multiple HDMI ports, unplugged power, ethernet cord - nothing I have done has remedied the issue. Initially, the screen did not blink/flash, now it does after having unplugged/plugged-in the cords. Before this week, the unit was functioning just fine. Any ideas on how to fix this issue? I have a TiVo Roamio for my main DVR and that is functioning just fine. Both units have a lifetime subscription.
