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.

sam: If your box "always" works again for a limited period of time after having been temporarily disconnected from the mains supply then that generally points to a defect in the boxes internal power unit, not exactly an uncommon thing to happen.

I hope to receive some advice from ye. Up to very recently I was getting perfect free to air reception on a sky pace box with the sky card upside down and this was over the last 3-4 years after I stopped having sky subscription tv.

I watched the tv one night last week and reception was perfect. The following night a error 29 message appeared, 'No signal received etc'. I am handy enough at TV tuning and checking leads etc.I dont believe its the dish that suddednly moved overnight and anyway had far worse weather over the years and I dont believe its the leads and rf cables as checked them too and look ok. I have checked the box and even updated it with the updated software and still to no avail so I am at a loss to know what it could be!

Could it be that the sky viewing card has expired?
Could it be that Sky have deactivated the signal given that I no longer pay for subscription TV or is that my imagination getting carried away?
Unlike the free to air non sky boxes the sky box requires a viewing card to view even the free to air channels?
If its the card that has expired or Sky has deactivated anyone know where I could get a cheap card or a way around this?

Larry: All Sky boxes no matter of what type can receive "free to view" programmes without a card inserted.

You should carry out a signal check by pressing "services" then 4-6, but if nothing is seen indicated on the strength / quality bar then its either the box itself has failed (usually the power unit) or that the dish has moved a fraction, other possibles being that the "F" connector plug might be internally waterlogged, or the LNB has developed a fault.

The only way you can verify one way or the other where the fault might be is by either trying another box on your dish, or alternatively your box on another dish.

Richard: When you say "community aerial" are you meaning dish? as a community (or communal) aerial is used for Freeview reception and not satellite, so if you are "not" meaning dish then that aerial connection is of no use for Sky.

Another point to note is that you cannot record or playback anything on a Sky+ box unless you pay a subscription to Sky, as only then will Sky unlock access to the recording side of the box, as otherwise the box will just operate like any other Sky box.

The other thing to keep in mind being that you really require to have two feeds from the dish for satisfactory operation of a Sky+ box.

On the plus side you should be able to receive non-subscription HD channels such as BBC / ITV etc.

I have a splitter which distributes Sky and Freeview. Since 18th April Freeview has a good signal 70% but Sky picture has deteriorated.I can no longer use reset method 2 or 3. could it be that my sky digibox is out of date?
