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.

Hi there,
We have sky in multiple rooms from the same dish, often we lose signal on just a few channels in both boxes. Method one always works in the Sky+ box, but on the Sky+ HD box it causes us to lose signal entirely. Anthing we can do?

Cara: Have you tried "Method 2"?

I could be that your dish has become slightly misaligned, if the problem effects more than one receiver.

Ok I have tried method 1 and 3 but still says 'this program is not available' (channel 178, ITV1 HD). I don't think its the LNB because both boxes are fed from the same (quad) LNB. But I must mention the second box is not paired with the viewing card.

Tareq: You don't need a viewing card to watch ITV1 HD, the channel is free-to-air.

One idea might be to change the LNB output your box is using, as you will have a spare one on the quad LNB package.

Hi I am in Denmark and i have sky, all the sky channels are working then i noticed i lost channel 5 then bbc1 +2 plus both channel 4s +E4s Before I could get bbc1 on the 980 channels most of the day and night if the weather is ok but since last winter as I have said they are all gone yet I still get ITV+1 perfect and as I said before all Sky channels etc no problem at all. I have a 100cm dish which is not impeded by anything. Can you help at the moment i am rebooting so lets see what happens but i have tried everything? Would a faulty lnb cause this yet still let me see sky channels or do you think the dish has moved. Thanks again Steve

steve: OK, this probably means your LNB is failing and you need to replace it.

Hi Briantist,

I was speaking to you last week with my signal reception issues - it was TREES that were the problem :-<>. We are out in the sticks and there are a number of trees in line with the dish which have grown considerably over the last 10 years, hence the gradual decline in signal quality, accelerated now they are in full summer bloom.

Engineer has re-sited the dish so we should be OK for a coupla more years now, it will be on the chimney stack next !

Thanks very much for all the advice given.

Best Rgds,
Nick H
