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.

marie fender: Hi Marie, the no phone line will not stop your sky box from working, the phone line is only used with the installers menue, when connected it decides which area your card recieves for your local programs. If you have more than one box swap them over and see if the other box works. If both fail check the cable input to the box, the F connecter is the worst type made they can come loose when you change or just move the box a little. Sky boxes often fail due to power supply failure due to poor ventilation and give the no signal report. If the box will not work in a different place it's cheaper to replace it than repair it, try ebay for a used box there are loads of them there qiute cheap. Good luck hope this helps.

my hitachi sat box sometimes shows the symbols L or d in its viewing panel but there is no reference to it in the handbook, the only way to clear it is to unplug the box, surely there is a reason and cause for these symbols?

Tony: If the reset procedures don't work, then you will have no actual signal.

This could be because the dish has moved, the LNB has failed, the cables are damaged or the box is faulty.

pete Clare: I'm not really sure what you mean by a "viewing panel" and why they cause a problem with viewing.

I used to have sky multiroom but ended this about a year ago. i still have my SKy plus downstairs with full subscrption and a normal sky box upstairs. Up until a couple of months ago all of the 'free to air' channels were available upstairs but lately the recption has started to go funny on some normal channels like BBC1. Can I do anything about this?

Mike: If reception is affected in any other room then its either caused by the box itself having developed a fault, or its connected to a problem with the multi- outlet LNB or dish alignment.

To check the latter, press "services" then 4 -6 and observe the signal strength / quality, which should be roughly the same at about 75% level, if not, or one is radically different from the other, then the dish requires slight re-alignment.

If though the signal readings are OK, then disconnect the box from the mains for a few minutes before powering it up again and letting it go through the usual "searching for listings" procedure.

Thanks for your help jb38. Ive tried all of the reset methods above and your tips but not working. The signal strength is mainly ok. If I adjust the LNB will this affect my already fine picture I get on my main box?

If my 2nd sky box in my bedroom is faulty I have looked at purchasing a freesat box. Can this be plugged straight into the sky dish feed without re-alingment?
