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.

I have a few channels missing at present which has just happened over the last 2 weeks or so.I have done all 3 types of resetting the box but I still have the few channels missing.On the settings page I have found that signal strength 2 keeps coming and going.On recordings of programmes they play pixilated.Any ideas please.

vic: There is nothing magical about Satellite reception, insomuch that if a dish has a reasonably clear view of a Southern skyline then there is nothing can stop the reception of a satellite signal except a fault with the equipment, or more likely the way its installed, the latter being the suspected reason for your particular problem as its extremely easy to get the alignment wrong, especially with the horizontal plane angle.

On looking at your original posting you mention that you have an old 75cm dish, and as these were not generally used for normal Sky reception I wondered if it has a standard LNB fitted to it?

That said though, the fact that you mentioned that you have tried a new dish as well as a new box still indicates a possible (and continuing) alignment fault as the reason for your problem.

Neil: With any problem that involves reception its not really possible to offer any constructive advice without knowledge of your location. (post code)

Vic- if the dish is 20 years old and a 75 cm the likely hood of it pointing at sky at 28.2 east is slim I would imagine its for when sky was analogue and was pointing at 19.2 east

So sounds like you need it realigning - i would suggest swapping the LNB

or a new mini dish

bob: If the dish hasn't moved during any exceptionally stormy weather, not of course that this would be noticeable to the naked eye, then its likely that high static rain has damaged either the LNB or the Sky boxes tuner.
