Dish Network DVR

You have what is called a diplexer in the back of the the receiver in the front room.It looks like a splitter.If it is put back on in the wrong way you will have a fuzzy screen.look at the diplexer,you will see in/out which would be the input on a regular splitter,then you will have one side that would be one of the 2 outputs that will say SAT,the other side is UHF/VHF.The chances are that when you plugged them back in you had them swapped.Try changing the 2 cables around.If that doesnt work try changing the assigned channel to 68.You can also try doing a auto channel search on the tv in the room without the receiver.this will find the channel that the front room receiver is broadcasting the signal on.Chances are though that your diplexer wires are configured incorrectly.remember,the in/out should plug into the back of the receiver (satellite in)and the UHF/VHF should be going to the other room with the problem and the SAT side of the diplexer should be wired to the satellite dish.GOOD LUCK! rate me with the outcome please.
