Well if you replaced the cable, it does not leave much more to check. The LNBF would be my next try. If you have a volt meter, see if there is 13v/18v coming out on the coaxial connector "SAT IN" at the back of the receiver.
Or if you can borrow a working receiver, you could try that to help prove what has failed.
