I am scratching my head over this one. I bought the Avenger pll lnbf 321s-2 for upgrade to my Openbox s10. I installed this puppy and am receiving 0 signal. Am i missing something here? I just figured i received a defective since by hooking my old lnbf back in place restored signals. I received the replacement Avenger and installed it to find the same results, no signal. I took my satellite meter to the dish to check the Avenger and have no signal with it also. Do you have any ideas guys?
