I have swm 16 setup with a 5 LNB dish. Suddenly the signal on all 119 tps has dropped to 0. The signals on the three 110 tps are in the mid-90s. Do you think it is more likely an LNB problem or a swm problem? All receivers are experiencing the 0 signal levels on 119. There are a couple of channels that come from 119 that we sometimes watch and I'd like to get them back. Any advice would be appreciated.
