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.

Hello, I use an old Sky+ box, I cancelled my contract for this box because I have 2 other boxes and wanted to reduce costs, but I still get all the freeview channels on this box in the kids room but the signal disappeared 15 hours ago. I still get the Sky News channels and a few others such as BBC 3 but the previously working BBC 1, 2, ITV and Channel 4 don't work any longer (many others too). I've reset everything I can and checked all connections but it still doesn't work. What could possibly be the problem?

For what it is worth,I have been experiencing intermittent signal reception on my SKY + HD box for about 1 month with the error code 25.The severity of the problem varied greatly from day to day. Following a discussion on the SKY chat line I ensured that all of the connections on the box were secure but the problem still persisted. This morning I found that gently moving the cables at the satellite dish has completely resolved the problem. I have now arranged for an engineer to come and check the connections properly but there is little doubt in my mind that this is where the problem lies

Just wanted to say Thank you very much for your help - can't believe Sky just wanted to send an engineer out and/or for us to upgrade to new box! The easy to follow steps helped solve our problem! Thanks again

david thomas: Press "Services - 4 - 6" and check if both the signal and quality is indicating around the equivalent of 60% or so, as this is the minimum level for reliable reception, if they are then observe them for a couple of minutes or so to check that neither bar is fluctuating.

Just ignore the telephone line warning.

Martin Warren: You cannot split the feed from an LNB to any satellite receiver whether it be Sky or Freesat as the box communicates with the LNB for purposes of polarity switching, with this being done by it sending a voltage up the coax.

If you want to run a second satellite box (Sky or Freesat) then this will require you using another port on the LNB, if it doesnt have one then you will have to fit a dual or quad LNB on the dish and run another coax from the LNB to the second receiver.

Quad block kits are obtainable from a number of e-bay outlets for around £10.00 and are easy to fit, especially if the present dish has a rectangular shaped arm from the dish to the LNB.

Martin Warren: Just noticed that you had mentioned about the HD working in the living room, "if" you are referring to HD via a Sky+ HD box then it will have two coax feeds going into it and with these most likely being from a quad block, should this be the case then make a close inspection of the LNB as it might have two ports spare inside the shroud that covers the tops of the "F" connector plugs.
