I have 2 minis.. Recently, when i turn on the TV to watch, the TV says no signal. The mini does not appear to be turned on. I unplug the mini's power supply from the wall, and plug it back in. This brings the mini back to life. This seems to happen a couple of times a month. If it was 1 mini, i would suspect that the mini is bad. But it's happening on both mini's in 2 different rooms.
