771 Again for DirecTV

This time it is the stick house. Simple installation, SWM 3 antenna 30' from receiver with no splitters. System has worked perfect for a year+ and all of a sudden, get the 771 error (can't "see" the antenna).

  • Swapped out all coax
  • swapped LNB's
  • getting 21V at the LNB
  • swapped receivers HR21 and HR24

I'm stumped. What am I missing?

    No, the dish not pointed properly will cause that problem as will a bad LNB. Can you get to the Repeat Satellite Setup (Satellite) on the menu? If so, get to the signal strength (not signal meter) and see what the receiver is seeing on all satellites. Have you tried changing the settings to allow SD version of the HD channels? This comes from the 101 satellite and may help with diagnostics.

    Thanks Donn but that's not the issue with a 771 error. Receiver isn't seeing the LNB so it doesn't know if the dish is aimed or not. That's my understanding.

    Dish has moved? Trees grew up and blocking the signal? Probably time to hite the bullet and hire someone to come out and troibleshoot it for you. Without an AIM meter your only throwing rocks at the issue.

    Defective dish or LNBs. Is the HR24 set for SWM and coax in connector 1? Is the HR21 SWM capable?
