I have 2 Tivo HDs and 2 Premieres...2 days ago both of my HD's stoped working over HDMI. I checked the cable and the tv and the premieres worked fine on these tvs/cables. Just seems strange that the two HD have the same issue at the same time. After rebooting, I get the welcome screen but when it goes dark as the harddrive goes live I get the lost signal message. Tried all of it. Power cycle, resetting the cables, even unpluging the TV. Any ideas?
