I am installing an Oval 3 LNB dish to my existing Directv services and have run into a problem. When I do Auto Detection of the dish type with my Samsung receiver I get a message it failed. If I manually select the Oval 3 LNB dish it does the set up but I get no signal what so ever. I am getting about 17v at the dish end of the cable and only have about 60' of cable so that isnt a problem. The Mounting pole is plumb, the Tilt and Elevation are set to the reciever's recommendation. I point to the azimuth and no matter how much I swing I do not even get a blip of signal. HELP!
