Why does my cable TV picture keep breaking up, and also ghosting? This has been happening since before Christmas, and is getting worse. It is making viewing intolerable. Note: Picture quality via roof top aerial is perfect, which rules out TV screen faults. I have tried switching off and on and rebooted several times, and all connections are secure.
It would appear that this is a Tivo box problem, or cable fault (Although I am not having any problems with broadband of telephone services).
