Hello I need your help. On some channels only (two that come immediately to mind are 501 and 218) I get the 771 error. I would like to try to fix it myself if possible and avoid the wait of getting someone out to fix it. I have tried the red reset button on the receiver and that didnt work, I also tried to reset via the menu. Are there any other things that I can try to solve the problem? Also as an aside, I have the full package, which satellites do I search on in the settings section there are a number of them....would it be only 99 and 103? I have the music channels, HD, movie channels in the 500's, and no international channels if that helps you answer my question. Thanks in advance.
