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.

Jason: Unfortunately yes, that's why this measure should only be used as a last resort, anyway see how you get on with your skew adjustment checks.

Charlotte: Please give your location, preferrably post code, so the chances of reception might be checked upon.

Are you using an indoor aerial and if so, is there not an outdoor one you can use? You might need to get a suitable lead to plug into the outdoor one, for example, if there is a wall socket for it but the previous occupier didn't leave the fly lead that connects from the wall socket to the TV/recorder.

Constantly having problems with the Input 2 signal on SkyHD box. This means I'm unable to record 2 things simultaneously. The signal comes & go's. This started before Xmas. An engineer came out & didn't really listen to what I said, he just reset the box without asking which lost everything on my planner. It worked normally for couple of weeks before starting to cause problems again. It has now been off for nearly 24hrs. Reluctant to call out engineer as don't want to lose everything again. Any ideas?

Mark: Have you tried viewing the signal strengths indicated on both channels for about 5 minutes or so just to see if one of the scales is fluctuating, as going by what you say has been done then it points to either a bad "F" plug connection on the LNB
or alternatively the block itself is faulty, or even one of the boxes tuners, as resetting it (the box) wont make any difference to that type of fault.

The other thing you could try for a test is swapping the two "F" plugs over on the back of your box, as if its No2 input on the box thats faulty then there wont be any difference seen with the problem, but if the problem is at the LNB end then there will be.

Yeah tried swapping the two "F" plugs previously which did originally work. When I do that now though the no signal swaps to Input 1 which suggests problem with the No.2 input. This is what I told the engineer but as I said he took no notice of what I told him. The signal on Input 2 came back on for a few hours this afternoon but has gone again. Plus the whole of my recorded programmes on the planner have now disappeared! Can see the box ending up in the garden soon :-/
