If the old dish is Dishnotwork then it may have switches/LNB that are not compatible with your receiver. If you have any switches remove them all and you might be able to get the few channels that are FTA on Dish.

You would also have to use the L.O. of 11250
If its a DirecTV dish it will be pointing at 101w and there is nothing there FTA (With an 18" dish), if its a DirecTV Phase III (Triple LNB) it again will default to only 101w
