Sounds like multiple problems. His changing the cable may have fixed one problem. If you've done a full reset including reformatting of disk, then you probably need a new box. Get a cup of coffee, sit in your favourite chair and play the game by calling SD tech support. Go through their song-and-dance calmly answering any questions and they'll soon send you a new box. You really have no choice, other than to choose not to use pay TV.
