I'm trying to hook back up my grandpas Direct TV system after he had his house remodeled. And between the siding being replaced and new sheetrock in the den, he cant come up with any of the cables and whatever else that went between the receiver and the dish outside. The model number on the dish is sl3k4nr0-01 that has 4 outputs, and he has a HD DVR inside. I can get the model number in the morning if its needed. Anything you can tell us will be greatly appreciated!!!
