Yesterday I moved my TV and had to disconnect my DVR and cable box. After I reconnected it my DVR isn't working. I can't access any recorded shows or record new ones. It just says the service is unavailable. I remember when the guy initially installed it he had to go through a specific sequence, but I don't have that. Could you tell me what I need to do to get it back working? I have a Pace DC700X box. Thanks.
