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.

Steve Baker: Your sat meter may well have been off the scale but are you absolutely positive that it wasn't actually on an adjacent satellite? as its extremely easy to make this mistake as there is only the slightest of positional differences between the two.

The dish being slightly out might even have been the real reason for your boxes initial failure, as blustery conditions could have moved it slightly. That said though it does have to be admitted that this type of fault can also be caused by the boxes power unit having developed a fault which reduces the voltage that's fed to its tuner, although unfortunately only way of knowing if this applies or not is by carrying out a test using another box.

Steve - what kind of meter are you using to check the signal , if you are using the kind with a needle on or a beep that gets higher pitched as you find a satellite then you cannot guarentee which satellite you are pointing at it only takes a few degrees of error to be pointing at the wrong satellite - try again but dont give up a day or a weekend doing it as many of my customers have done in the past, if you are struggling then call in someone like my self - I charge £45 for a standard sat dish re alignment - obviously prices will vary from area to area

Hi, Any ideas on why a number of my sky channles are showing no signal or are breaking up. I have changed the LNB and re-aligned the dish to the best of my ability but still no difference. Both the Sig Strength and Sig Quality reading for both feeds are showing almost full scale on the services pages. The typical sympton is that I get the BBC chanbels but cant get a Sky news signal.Is this likly to be a box related issue rather than signal? hoping you cna help with some advise - many thanks in advance. Mark

Hi - if you are sure the dish is lined up properly then it does sound like a box related issue - one way to test this is to either take your box to a friends and connect up there and see if the box springs to life - or to bring a spare or friends box to your dish to see if the problem remanes on the other box - we as satellite installers can test the signal a whole lot more reliably on our test equipment we can see if one of the polarities is down - you could have border line signal and your box will show good

Another thing to try first is a software update - find the back up button on your box - (not the remote ) reach round find the power cable un plug it - wait a few seconds for the box to power down press and hold the back up button and insert the power cable keep the back up button held down untill all the lights come on - then give it half an hour to update (says 10 mins on screen but some boxes take way longer) - do it before you go to bed and try it in the morning !

Hope you get it sorted

Hi. Recently I upgraded to HD and had a new box and cables installed from an existing dish. Over the past few months I have started experiences problems, namely that I lose signal from only one of the inputs.
I've tried all of the suggested fixes (reset lnb, software updates etc) but nothing seems to reliably fix it. I have fiddled with the cables that go into the back of the sky box, and when I've switched them over in the past the signal has picked up and worked. But today, no matter what I do, I can't get the 2nd input to receive a signal. Is this a dish or lnb problem? Can anyone help because I'm going out of my mind!

Steven check the cable - a single strand of braid touches the inner copper core then it will short out causing loss of single - also sometimes the inner copper core bends and doesn't get inserted into the connector properly - check the cable

Thanks Keith. I have already disconnected and re-fitted the f-connectors and I'm pretty sure there was no loose braid touching the copper core. I'll re-check and maybe even cut it back to make a fresh connection. Would an old LNB or dish cause this type of problem too? I was looking at he dish earlier and it does look old and slightly rusted.

I have lost Meridian South East on Sky although other people still have it, and other's I know have lost it, any reasons. Yet I can add Meridian South as an extra channel.

Have lost Sky 1 HD ONLY! - everything else works fine including normal Sky 1. Have tried the normal resets etc - even the menu works for SKY 1 HD BUT when I go on to it I get a "no signal" error....Why would only one channel disapear?

We no longer subscribe to Sky but use the boxes for freesat programmes, however I can longer get ITV1 Meridean, and I believe I will lose other channels too soon, do I need to get a freesat card to replace the sky viewing card, and can I get it from any other place apart from sky.
