How to Reset a Sky Digibox when 'No Signal' appears.

Reset method 1 - Delete and Rescan

  1. Turn the power off at the mains socket. Either do this by pulling the plug from the socket, or using a power switch if there is one.

  2. Remove the viewing card from the machine. Using a dry cloth or kitchen roll, clean the gold connector on the reverse of the card. Do not use any cleaning products.

  3. Check cables and connectors are in good order.
  4. Wait for at least 30 seconds.
  5. With the card still out of the machine, plug the Digibox back into the mains.
  6. Ignore all the messages, and wait for around a minute.
  7. Try 101 for BBC One, 102 for BBC Two and 103 for ITV-1.
  8. Insert viewing card, wait a few seconds.
  9. Check 104 for Channel 4 and 105 for five.

Reset Method 2 - Reset the LNB

If the above method does not work, the LNB may have a fault.
  1. Press the [SERVICES] button and then press [4] [0] [1] then [SELECT]

    On Sky HD, press the [SERVICES] button and then press [0] [0] [1] then [SELECT]

    Press the buttons in the sequence above exactly - do not atttempt to use [UP] or [DOWN]. Note that when you press the second 0 and 1 nothing happens on the screen until you press the final [SELECT]. This is a "hidden menu".

  2. Then press [1] to go to the RF output menu.
  3. Press [DOWN] three times to highlight the line 22Khz Command and then press [RIGHT] to change the value to [OFF].
  4. Press [DOWN] and [SELECT] to select Save New Settings.
  5. Press [SKY].
  6. Again press [SERVICES], [4], [0], [1], [SELECT]; then [1] again for the LNB Menu. (SERVICES 0 0 1 SELECT for Sky HD).
  7. Now press the [RED] button (reset all settings), then [DOWN] until you can select Save New Settings again.
  8. Press [SKY].

Reset Method 3 - Upgrade the system software

If there are still problems:

  1. Turn the Digibox off at the mains again and remove the viewing card.
  2. Whilst holding down the BACKUP key on the Digibox - NOT ON THE REMOTE - turn the mains power on.
  3. Keep hold of BACKUP until the screen displays a "UPGRADING SYSTEM SOFTWARE" message – this will be white text on a black screen. On some boxes this can appear as a half screen.

  4. Wait 10 to 20 minutes for the software to download and install. The box will restart when the process is complete.
  5. Ignore all the messages, and wait for around a minute.
  6. Try 101 for BBC One, 102 for BBC Two and 103 for ITV-1.
  7. Insert viewing card, wait a few seconds.
  8. Check 104 for Channel 4 and 105 for five.

Ok wi33 re-check all connections and also the LNB connections and spare outputs before popping down to Argos then.Incidentally Argos's Q&A on the LNB has the following response posted for the question of whether you can install this without employing an engineer.You agree?

Yes do call an engineer to set it up see why below!

How easy it is will depend on how high your dish is up the wall and if you have a head for heights. And you would need to be able to reach the end of LNB on the end of the long arm that sticks out to change the LNB with out moving the dish either up down or to the side if it does move on you by accident you have now lost the calibration to the satellite, this will result in a poor signal in bad weather or complete loss of picture, don't move the dish or push and pull it will move on you.

Before changing your LNB it is very important you switch off any existing satellite receivers and unplug it from the mains wall outlet power socket. Satellite receivers send power up the coax to power the LNB and if you unplug the coax at the back of the receiver with the power still on you could by accident short out the copper wiring in the coax is will cause a special PCB fuse hidden inside the receiver to blow and that will be the end of your satellite viewing, the same thing applies at both ends of the coax if you plan to do any DIY.

Would this one do the job as an alternative to the Argos LNB?

(01-36) Quad Output LNB for standard UK Sky minidish

I have just got a Sky plus hd box which I had to self install. I had no problems until about 1 hour later. The HD box went into standby. The remote would not work so unplugged everything and it worked again. The same happened 1 hour later. Repeated and worked rest of the night. Next morning I cant get nothing. I have tried everything and I cant even get it to recognise HDM lead. I have phoned up sky and they are sending out engineer next week. Is there any other way to get this to work

Janette : "is there a problem with sky in Spain as no one seems to be getting a signal"

There are no problems with any signal at all - not too sure about "no one is getting a signal" - as many of all clients are OK, as are many others.

Perhaps if you are on an urbanisation and sharing a dish, and you are getting no signal, then it is an issue with your distribution system?
Or some of the weather we have been having recently can reduce the signals.
If you are still having troubles, then your exaclt location, dish size, receiver make / model, and if you are on a community system or not would help in diagnose the problem.

Hi, thanks for that. Step 2 returned my channel 5, step three brought back 4, e4 and film 4 (now lost channel 5 again but may be temporary). Again thanks, your three steps were really valuable.

Hi, I've tried all three methods and still 'no satellite signal is being received'. The signal and quality strength are good, all connections are good, the dish is fixed well to the outside wall. It all worked perfectly before the warm weather!!

Tracey: The could be a problem with the box, assuming that the dish has not been moved.
