Advertisements Well, the power cycle used to fix everything for a few days. Latest time I tried when Tivo booted up I get a black screen. No, it's not just a black screen. There is no video output at all. Have not been able to watch in a couple of days now. Some scheduled recordings and suggestions have recorded and I can transfer via MRV and looks like everything recorded OK. Just no video output from Tivo HD. Using HDMI. Monitor says no signal detected. Man, if I had known Tivo HD was this squirrely I think I would not have bought it. Gray screen problem was bad enough, but this!!
