Okay i had my dish mounted in yard on steal post by installer. Some punk kid took bat to it . My neighbor moving out gave me his (exact same except for serial number) hooked it up signals great but no channels. Direct wanted to chrage several hundred to get me re-hooked up. I have d12-500 receiver. I was told i need to reprogram to new LNB but how anyone got a link or video to watch . Please. Not trying to hack anything just can't afford Directs "fix"
