I hope someone can help me! My satellite began experiencing problems that appeared to be rain fade for brief periods awhile back, even though it was a perfectly clear day. Eventually, I was not able to get any programming. The high, even number transponders (28, 30, 32) showed a signal in the low 90's. I found a bad coax in the system, replaced and still the same. Everyone told me it was an aiming problem - so I bought a satellite finder at radio shack and "fine tuned" the dish. Same problem. I changed the LNB with my father in laws - same problem. I took my receiver to his house - same problem. I brought his receiver to my house - same problem. I had Directv send a new receiver - same problem. Does anyone have any ideas??? Thanks.
