I have recently purchase a DirecTV system with UltimateTV receiver. I have self-installed. I believe I have set up the azimuth and elevation correctly but the signal meter shows no signal whatsoever.
I have run the system test screen which says both tuners are "OK" when they are not connected to the LNB, but "Failed" when they are connected.
I've tried another LNB, same result.
What could be the problem?
Could it be the receiver?
