Question about RCA DRD480RE Receiver

1 Answer

No power to LNB

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?

    Thanks for the suggestion on how to check the receiver. The receiver checked out okay. It appears the LNB may be bad since the receiver is putting out the correct voltage.

Use a multimeter set to DC, positive to center conducter, negative(ground) to outside of connector. Should read about 13-18V.

Ikonvert TV converter box is reading lnb short what is this


'LNB' is low noise block. It is the receiver that is located in the middle of your satellite dish where the signal is collected from the dish.

You need to check the wiring at the rear of the receiver and all the way to the LNB itself.

Error 771


ok explain a little more please. Make sure U have the coax coming from the Dish (outside) going into the back of receiver where it says SAT in. or if it is a dual tuner (ie: 322 etc) make sure the coax in hooked up to the Separator. also make sure u are using the correct dish and lnb to match ur receiver. I ALWAYS do a "check switch: every time I hook up to a new/different dish just to make sure the receiver recognizes the LNB.

Lightning struck pole outside my home now my tv screen is pink I don't know if it's my tv or cable box!


For sure your TV. But you still have to replace your Antenna Cable, if not the LNB as well.The LNB is the "EYE" in front of the Dish. You do not have to replace the Dish.

My dish 311 receiver goes on and off when connected to dish pro plus lnb


rdjennings10,

It does sound like there could be a power problem with the receiver. The Dish Pro Plus LNB won't cause any issues with that receiver. If the receiver is plugged into a power strip or surge protector, try plugging it directly into the wall. If it is already directly into the wall, try a different outlet if available.

If the problem persists, we will have to replace the equipment. You can reach me at thomas.faust@dish.com to get that taken care of.

If you can monitor the supply to the LNB, you may find it is low, unplugging it when the decoder is powered up allows for more power. I would change the power supply capacitors if more than a couple of years old.

Hi mfpayton with the install of the brand new receiver wealways want to make sure all connections are tight. And after all connectionsare hand tight we will need to run the Check Switch Test. It will provide thestrongest signal to your home and you will see the signal move up into the 65percent range. If after the Check Switch Test it still is a low signal we mayneed to check the connections from the Dish and LNB that is an issue we wouldneed to come out on. I will leave the link to show you how to do the CST.http://www.dishnetwork.com/SupportSection/complete-sig-loss

How do i fit a dual LNB so i can change channels


HELLO
A word of warning! Do not attempt to split any feed coming from a single output LNB to another satellite box - you will be asking for trouble!
Now for the solution. If you are using a standard sky minidish you will need a 40mm adaptor kit, a dual output LNB and another length of satellite cable (Webro WF100 prefereably) but I suppose RG-6 will do the job providing it is not too long (around 10-15 meters or so) a couple of F connectors and self-amalgamating rubber tape.
Power off everything! Remove the old LNB and to do this you'll notice a plastic rivet on the LNB arm of the dish which must be removed. When you have done that and the new LNB is place (don't tighten everything yet), connect your current length of cable to one output and the new length to the other (finger tight should be fine) and make sure BOTH of your boxes are connected. Remember to waterproof those LNB connections.
Power on! You should be getting pictures - if not the LNB will need skewing round a bit. Look at the dish from the front and turn the LNB in a clockwise position say the 2 o'clock position - that should do the trick. Then tighten everything.
I wish you well with it - good luck! (:-)

Hi. I need help finding 119!


I looks like you are picking 110W with the LNB on your left if you are facing the dish.
Try to get 119W first if you connect the cable to the 119 LNB, once you find 119W that way, you will also have 110W.
Good Luck.
