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.

SKY Aerial : On side of house near top, around 15/20 feet off ground.

Normal Aerial - On chimney, 30/40 feet up.

Hi - [seemingly] since the analogue signal has been switched off in Shropshire (Wrekin transmitter) I appear to have lost reception on a lot of sky channels e.g 110,401 -> 405,432 - even reception for channels like bbc1 can be hit and miss (quite a lot of the freeview channels also have iffy recption).Other channels still seem to be absolutely fine. This has only occurred recently (hence thinking it is related to digital s/over),the aforementioned channels were all A1 until very recently. I have not tried the above reset sequencing yet.........any suggestions as to where I start plse. Many Thanks !!

Nick H: It is utterly impossible for the terrestrial signal changes to effect your Sky reception.

Please try Method 2 at the top of the page.

If I upgrade system software I assume this doesn't affect any of the recordings I have on my box ?

Rob - Upgrading system software or doing a factory reset should not effect recordings already made and stored on the HDD.

Hi Briantist,

Tried Method 2 as instructed, all went to plan but issues not resolved.

Also tried Method 3 - issues still present and we just seemed to have lost all the sky channel listings :-(

Next ?

Many thanks for the advice :-)

Rgds, Nick

Nick H: The most likey explanation is probably that the LNB has a fault, and you will have to replace it.

Hi Briantist,

Are LNBs easy to replace yourself or is it something best left to an engineer to sort everything out ? I'm no techie (as you have probably guessed by now :-) )

If the LNB was covered in dust/cobwebs etc would that affect reception i.e would cleaning it up potentially make a difference or not ?

Many Thanks again :-)
