What model # and how old is your Winegard. The Winegard box with SWM should be showing 99*, 101*, 103* You might have the original Trav'ler which was actually a 5 LNB setup (3 "eyes" but one of those contains 3 LNB's for 99, 101 and 103. To make it SWM you had to add the SWM8 kit (silver box with like 10-11 ports) and a PI29 power supply. That antenna would have been the SK-3005 and not the current SK-SWM3 which only have a single "eye" housing the 99, 101 and 103 LNB's.
Has this setup ever worked with the current receiver and what receiver are you using? Also be sure to go to a channel you know you should receive like FOOD at 231. You may be away from home and still trying to pick up local channels like 3, 5, 7, 8, 10, etc. which you cannot once you are out of range.
Let us know a bit more and let's see who can help.
