My Mini (9300) is stuck on a screen with a Tivo image with a smile. Unplugging it does nothing but go back to that image. I was wondering if their is a reset button somewhere? At least I had an old 1st gen version mini in the closet that works. Using the same HDMI, power cord and Ethernet worked, so the issue is not any of those items. Why the Tivo is smiling I'm not sure, he should have a frown, like the old macs used to have.
