Cablevision aka Optimum cable television Tivo Premiere - Series 4 platform Cablevision Long Island east end system Problem: Missing channel 102 Cspan 3 My Tivo Premiere was working flawlessly for two years. About 2 weeks ago I started getting a black screen with the message "This channel is not authorized." when I tried channel 102 - Cspan 3. Called Cablevision service and the technician showed up near the end of the appointment window. He did not have a replacement cable card to try as he said someone else had taken the last three cable cards in the warehouse. After a new binding of my existing cable card and a long chat with his shop he determined that channel 102 was on the wrong frequency. No solution was offered other than to try a new cable card. I went to the Cablevision east end Long Island system center and got a new cable card, installed the new card and had Cablevision bind it, rebooted and had the same problem - no channel 102. I put the old card back in to see if any help. It was not. When I put the new card back in I did manage to black screen a couple of channels around 102 that had worked. Any thoughts?
