Someone just gave me a 4dtv 920 receiver. It works great. Got on sat, got it to download channel lists, things looking good. But, someway the east west limit are set the same or within a couple of numbers of one another. I have tried the "set limit" options but it won't let me change the numbers more than 1 or 2. So now when I try to move automatically to another sat i get the message reached physical limits. but the dish doesn't move. Is there a way to override this? Is there a factory reset that would take me back to default? any help? Thanks guys.
