Hi, my name is Bill and I'm new to SatelliteGuys. I work in a dish network retail office and I was just looking for some advice. I have a customer who ran cable from his main receiver downstairs, and it's hooked up to the TV with just a screw on coax. His TV however will not display the Dish. Is there something we need to do to program his TV to be able to display the satellite? any suggestions would be much appreciated. Thank you.
