I need some help. I am new to this site. I have been a Dish Network customer for 10 years with a active receiver at a different address other than my current service address for several years. I have had a few LNB go bad and have replaced them, and have also had to realign my dish a few times. lost signal after a heavy thunderstorm about 3 weeks ago. I have tried 3 different LNB, one has not been installed since I bought it 8-10 months ago and one that came off my house(was working when removed) after an upgrade. I have had the worst time trying to tune in signal for Dish Network 119 and 110. I have checked the cable, good. I brought the receiver home, plugged in it was good. Can someone provide me with some ideas as what to try? Any way to check a LNB to see if it is good?
