Hi all, I am totally new to this and would like to start off by asking a few questions. I have Dish network but im not really sure which receiver i have. when i push system info, i see 102 rev1 07 and i know i use satellite 119. i guess the keys have changed because i can't see any channels and usually when this happens, there some guy who helps me fixes it up. but im just tired of waiting on him and would just want to learn how to do it myself. how would i start in doing so? how do i put in the new keys? sorry and thank you for your time.
