I was using dish pro twin lnb. few days ago I changed the pro to single LNbs. When I did that I lost 110 completely and 119 was woking fine. now nothing is woking. When I test signal by the dish, it's says good signal but I don't know how to check it on fortecstar ultra. can anyone tell me what am I doing wrong. I am using the same switch as before. help plz..thanks
