Advertisements I skimmed through most of this thread and didn't see my problem. All of my channels are black screens. If I hit live TV, I can't see anything (just a black screen). I called Comcast and they're sending out a technician for no reason tomorrow. It's clearly this update. They tried repairing the cable card and said that everything looked fine on their end. I have three messages on my TiVo: 8/30 TiVo Service Upgrade ("Over the next 24 hours, you may...") 9/1 Show Info Has Run Out (M60) ("The TiVo box has no information about upcoming TV shows & movies. Please connect to the TiVo Service now. ...") Then I connected to the TiVo service, then got: 9/1 A lineup change has occurred It listed all of my channels as deleted, then all readded with different names. Now if I go to Live TV I see a black screen with a blue TiVo alert box that says "Searching for a signal on this channel. (v52) Press SELECT for help." (On every channel). Please help.
