Please help!!! I recently lost a majority of my HD channels, so I checked my satellite signals and saw that I cannot receive signals for all transponders in satellites 103 and 119. I have a 5 LNB slimline with I believe a built in multiswitch satellite dish (but really only has 3 LNBs.) Went on the roof today to see if the dish was loose, but it seems pretty secure. I dont know if one of the LNBs pick up those two satellites and they are bad, or if the built in multiswitch is bad? Your help is greatly appreciated. Thanks!
