My new receiver can't find the satellites. I have a DP Superdish for 119,110, and 105. I have a Dish 500 with DP LNB for 61.5. They are connected via a DP44 switch with two cables returning to the house to two separate rooms. Currently I am operating with 2 DP301-13 receivers. I tried to upgrade to the 625 first by using the separated included in the receiver package and then going direct with a cable into Sat 1 only. I both cases the receiver can't find any satellites. Can anyone offer a suggestion?
