Advertisements 3 year old Premier 4. Xfinity cable card. Suddenly today, I can't get a signal on any channel. Not the standard network channels (which should be unencrypted) or the encrypted premium channels. I get a "searching for signal on this channel. (V52)" error, on all channels, and all 4 tuners. An older HD TiVo I have in the house is still getting all channels just fine so I know I've got a good cable signal into the house. All the other functions of the Premier TiVo work just fine (menus, watching old recordings, Netflix, Guide etc.). Just can't tune any cable channel. Using the diagnostic tool on the TiVo says signal strength for all channels is 0. TiVo support told me the problem was my cable card was not paired. Called Comcast who re-paired it and it still didn't work. They say I need to get a new cablecard. I'm skeptical it's a cablecard issue because I can't even get a signal on the unencrypted network channels. Is it possible that the tuner in the TiVo died?
