I get the error message "No power to LNB" on my motor home dish. The dish come up and rotates but then does the emergency store. The manual says disconnect power to receiver then resore. I have done that but it does not help. It says replace the receiver. Is there a way to check to see if there is power coming out of the receiver?

were you getting all the Satellites before? could be Tree limbs in the way (very very common) could be the Dish had moved.. rotten boards, etc make sure the dish is mounted solid. could be the LNB gone bad. or coax has corrosion etc, many things can cause it. but usually a easy fix..
You more than likely have a problem with your power supply. Home theater receivers have many different watchdog or protection circuits. If the power supply is not output the correct voltage or is shorted that will trigger a fault. You could also have an overload condition on the output stage. Too much current drawn by the amplifier will trigger a fault.
No, you won't get significant signal in the FM spectrum from your satellite LNB coax. The dish is tuned to pick up signals of a very different frequency, and aimed to reject any signals not coming from a very specific direction -- up where the satellites are.
For FM, you need to receive signals from ground-based transmitters, in a different frequency range.
That said, you can totally use the coax to bring signals from your rooftop down to your stereo. To do this, you'd need to get up on the roof, disconnect the coax from your satellite dish and attach it to an FM antenna.
If you are using a switch between the viewsat and the LNB, remove it and connect the receiver again.
If that did not work, remove the cable from the LNB and power up again; if the receiver still unable to power up then you might have a short circuit in the cable itself or water might be entrapped inside the connectors on the LNB/switch connections.
Let me know if you need further assistance.
Here's what the Bose support website suggests. Good Luck!
Messages displayed during a Music Information Update
Messages may appear on your media center display during a Music Information Update. If you see a message with instructions to call Bose, and a three-digit code such as "Error Code 802" or "Failed 172" while performing a Music Information Update, it does not necessarily mean there's something wrong with the system. Performing a media center reset and installing the update again may address the issue.
To reset your media center, follow these steps:
Turn the media center off. Wait two minutes
Unplug the power cord from the media center. Wait 30 seconds
Reconnect the power cord
Wait until "Bose Lifestyle" disappears from the screen
Note: After a reset, you will need to wait several minutes before playing stored music (3 to 20 minutes, depending on how many CDs have been stored). All other sources will be available immediately after the system powers up.
If you have any additional questions about these messages, please contactBose® Technical Support or call 1-800-278-1281.
1) Problem with LNB
2) problem with cable
3) problem with receiver
It's hard to check the LNB unless you have a spare one, but you could switch the cables and see if the reciever reports a switch in the good channel to the other side. This should tell you where the problem is.
Of course, it could be a carrier problem, but this is not likely, especially if it continues for a long period of time.
From experience, I suspect that the dish has lost it's optimum "focus" on the satellites, and your signal has dropped. In your case, tuner #2 just happens to need a little more signal than tuner #1 - and that's revealing the root problem.
If you can have a second person handy, use the signal meter function and view the signal. Then one person should move the dish a bit (likely upward a hair). If the signal goes up with just the slight movement of the still tight dish, that's the problem.
