I had a funny thing happen yesterday. I fixed the problem by resetting the tuner, and thought I'd explain the situation to save others the hassle of talking to Tivo or Comcast/cable co.
I was channel surfing and suddenly could not get any channels. There were no error message, nothing telling me the channels were not authorized...all I saw was a big, blank (black) screen. Then the channels came back, but I determined that that was because Tivo changes tuners when surfing if another tuner is already on that station. So I swapped tuners, and all of tuners except one were showing something. The tuner that showed nothing was supposedly tuned to channel 702 (local PBS).
I then went to my DVR diagnostics and looked at each tuner. The info for the first tuner was completely blank. Every other tuner was showing a signal and was tuned to a particular channel - but no tuner was showing channel 702. I figured the cable card had failed and was anticipating yet another afternoon waiting for Comcast to send a truck over. Before calling them, I thought I'd try to reset the cable card. There is no easy way to do this, so I went the 'unplug everything route'. I unplugged the cable card from the Tivo. Then unplugged the Tivo. Waited 10 minutes, plugged the cable card back into the Tivo, and then plugged the Tivo back in. Cable card was reset and all of the tuners are now working.
Note this is not restarting the Tivo. That doesn't automatically reset the cable card.
