I have the Winegard AS-2003 automatic satellite mounted on my 1976 Sovereign
and I use Dish TV. I installed this unit in 2004 and it has worked flawless until just recently. The unit has a GPS connection that locates the satellite's based on the "Dish TV" switches preset in the unit. Under normal conditions the unit searches for the satellites and maps them in memory. If you change channels between one satellite to the other the dish willl move to that satellites position. But now the unit goes through its search mode and appears to find the satellites but locks on to the wrong satellites. I have replaced the LNBF thinking that may be the problem but it still does the same thing. I have tried to connect in 4 different locations with the same results. On the Winegard control panel inside the trailer the Off and Search lights stay on and the trouble shooting section in the manual indicates that this means the unit has failed to see the satellites.
Anyone ever had a similar problem. Could it be the installed GPS? I have talked with Dish and of course they say it is not a problem with Dish. Before I call Winegard I thought I would get your comments.
