771 searching for satellite signal, only on some channels

I have an SD receiver that for at least the past week has been constantly showing the 771 searching for satellite signal on some channels while others come in perfectly fine.  For example I can watch Bravo but USA is searching for signal.  My local ABC channel is fine but CBS, NBC, and FOX are searching for signal.  My other receivers and dvr are all fine for every channel.  I've tried unplugging the receiver but it didn't change anything.  Any suggestions before calling Directv?  Thanks.

Re: 771 searching for satellite signal, only on some channels

What model SD Receiver do you have?

Please post back with your signal readings for each satellite's transponders (and both tuners if applicable).  You'll find these readings under "Menu" -> "Setup" -> "System Setup" -> Satellite -> "View Signal Strength".  Note the "+" and "-" symbols next to the "Satellite" and "Tuner" entries where you can toggle the readings between the various satellites and both DVR tuners.

Fill in your readings for each satellite and tuner using these examples.  A properly aligned dish will show 80-90s on most of the relevant transponders (although some will be low or zero):

I have same problem except its the HD receiver. The techs that come here have less knowledge then me, & I'm not that smart. I also jumped all the hoops  & ropes. Now says no dish found? Please post if you get the answer.

PS: the 2 standards have limited channels.

It's a D12-300.

Surprisingly, the channels are fine now.  I did nothing.

Thanks.  If it happens again I'll get the signal readings.

Re: 771 searching for satellite signal, only on some channels

Best to start your own new thread .  In that new thread, let us know the model numbers of your DirecTV equipment.  And post the signal readings from all of the satellites, especially 99º(c), 103º(ca) and 103º(cb).

Re: 771 searching for satellite signal, only on some channels

A dish that's is out of alignment may have signals that are on the edge.  Sometimes they provide a good picture, sometimes they provide a 771 error.  If I were you, I'd take 5 minutes and look at your signal strengths and post them back.

Thank You for all the help advise.  Problem is $1,000, short to cut trees blocking certain feeds.  When the leaves fall maybe I can fell them myself.

For some reason I didn't get notification of this response until today.  If I have time tonight I'll post signal strengths.  I have a dvr and 2 other receivers using the same dish.  None of them have had this issue.  Wouldn't the dish be out of alignment for all receivers?

Re: 771 searching for satellite signal, only on some channels

Post those readings.  They might be right "on the edge", so that not all receivers are as affected.  Or you might have an issue that's only affecting this one box.

Re: 771 searching for satellite signal, only on some channels

you are missing all of the even transponders.  this is usually a sing of a bad (corroded) connector somewhere in the line feeding this receiver.  check the coax connectors, specially outside on your ground block and or multiswitch
