Got new remote and it won't work with my receiver, don't know how to program it

You probably just need to set the remote address on the remote to that on the receiver.

Press menu twice on the front panel of the receiver and you should be able to see the remote address displayed. If not just press and hold the SAT button down on the upper left of the remote until all lights light up across the top and release. Now key in 0-1 and press the pound sign. The SAT button will flash three times and now press the record button. You should now be able to control your programming and receiver. Thanks for using Fix Ya. If you need further he; let me know.
