My pansat lost all channels like everyone elses a couple of days ago, so my supplier stopped by yesterday and dropped off a new 2500, he set it up ran something that collected all the channels and I had tv. Instead of saying nagravision in the left hand corner it said echostar. What is the difference? Either way I had the movie channels and many others (no Pr0n or Gee Fore). I turned the reciever off last night and turned it on this morning, to my dismay Every channel said No signal. Does anyone know how I can fix this?
