I am trying to install a motorised system and have come to a grinding halt. I am puzzled by the fact that the signal strength, wherever I point the dish, stays at about 80% with a signal quality of 10%. I even took the LNB arm off and pointed it at the ground with the same result. When I disconnect the LNB input cable the signal strength falls to 8%. I have checked that the receiver set up (technomate 7755) is correct. Am I missing something obvious or do I have a faulty LNB?

I remember a receiver which showed a high signal strength without pointing at a satellite, the quality reading was all that changed, it could of course be a faulty LNB, or perhaps even the receiver. You really need to swap both with known working units as a process of elimination.
