I have a Tivo Mini that quit working on HDMI. The TV just says "no signal". If I unplug the mini, and plug it back in, I can see the bootup splash screen on the TV while connected to the HDMI input. After about 30 seconds or so (when the mini transitions to the second bootup screen), the screen goes blank and says no signal. If I switch to AV inputs, I find the mini is working normally. I can jump back and forth from AV to HDMI. AV works as normal, but HDMI only works until the end of the first bootup screen. Since a mini has no recordings, and thusly nothing to loose but time, I tried to Clear and Delete Everything. C&DE did not help. Any ideas? I would expect a hardware problem would not allow the bootup screen but nothing else, and I would have expected a software problem to be resolved with a C&DE. Is there a more thorough "hard reset" type of process? Does anyone have any other ideas? Thanks!
