Any help appreciated! Today my Sky pic has disappeared with the "No Satellite Signal is being Recieved" banner on screen on every channel. My question is that i can still get the TV guide up and my signal test shows strength/quality at 60/50% respectively(my normal readings)? Could my dish have moved enough to affect my pic but not enough to lose signal completely? or is something else possibly wrong. Have checked all connections round back of Tv/Sat box(dont see it could be box fault as wouldnt get tv guide). Also are my signal strength/quality readings typical, should they be better(neighbour has 75/60%), could they be improved by a better/bigger dish or new/better LNB?
