I purchased a Pansat 2500a receiver and a network tv dish with dual LNB. Could not get to work, so thought I had to set it back to factory settings after messing with it for a while. When I did I get a bunch of saitillets showing insted of just the echo 110 and 119. After working with it I found echo 7 and scanned for channels. It came up with them. Have a good siginal at 87% and quality at 94%. All the channels say scrambled or bad channel. The radio channels work. Did I do wrong in setting back to the factory settings? Help. I don't know what I am doing.
