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.

joan: This usually happens because there is no signal being provided to the receiver, which means you have a disconnection or a fault.

I know this is a stupid situation, but I am desperate.

I live in on the 5th floor of a block of flats. The manager says there is a dish on the rooftop connected to every flat. Now, I have 3 wires coming out of the living room wall. I have connected each wire to the TV card on my pc but I still dont get any signal/reception at all.

That probably means my flat is not connected. Can there be anything else?

I have had no signal since the second switch off even though I have the early panasonic sky box and satellite dish. I have tried your instructions,I put up a new dish,I put in a later sky box,I tried a new sky card,I bought a new Toshiba led tv, I put in a new cable and I retried your guide at each stage.Sky said it can't happen and my local aerial expert is baffled too. I am the only house in my row affected. Before I go fibre optic I thought I would ask the question;"can you offer a suggestion?"

Tony Richards: If you are referring to what you have seen regarding analogue switch off's or alterations taking place on Freeview, then there is no connection whatsoever between these events and your problem with Sky reception.

Sky is quite correct in what they say, because nothing will restrict satellite reception provided that the dishes view of the skyline has not been obstructed, as other than that the problem you are experiencing just has to be caused by either defective equipment or that the dish is not aligned properly.
