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.

Tommy Johnston:
A "Freesat" box will,when you input a post code, automatically install all channels in the correct positions. The only time you need to input frequencies is to tune the free to air channels which are not part of the "freesat" line up.
The post code denotes which regional services you will receive.

To all who are getting intermittent loss of signal on Sky with a message about unplugging, etc.
It is worth waiting for several minutes before trying anything as there are not infrequent loss up the uplink signals to the satellite so none to beam down to us. Worth changing programme to see if others are also affected. For example, tonight we lost Alibi for some 10 minutes - but BBC1 was fine all that time. The signal returned with us doing nothing.

I have a strange problem. I can't watch any hd channels on my sky box unless I reboot my box. They then come back for a bit before going into "No Signal" mode again.
Have checked the cables connected to the box and they seem fine. Everything else I've read is for complete loss, but as I mentioned, it comes back after a reboot (but don't want to have to do this all the time)
It's been like this since it was installed but I have just lived with it, but now I have movies so really want to watch them In hd.
Any advice would be gratefully received. Thanks

Jo: If the problem referred to applies to all HD channels then rather than going through the process of rebooting your box leave it sitting on the same channel and remove the viewing card for about 5 minutes or so to allow it (the card) to cool down before reinserting it again, if the HD channel returns then this can point to your card being defective.

That type of problem can also be caused by a defective box, the fact of the problem being there from the start somewhat suggesting that the box could well be defective.

You should also try checking the signal levels received using the undermentioned procedure.

1:- Press "Services" on your Sky remote control and you will see the main menu with "Options" highlighted.

2:- Highlight the Settings menu using the right arrow button and press select.

3:- Use the left / right arrows scroll to "Signal" and press select.

4:- The signal strength / quality will be indicated on the grey bars.

If the strength / quality is being indicated then both of "has" to be around 52% minimum for reliable reception, this should be tested prior to the HD channels failing then once again afterwards to note if anything has changed.

Thanks for your response jb38. I'll try the viewing card idea you suggested. The signal on the 2nd input is alway 0 when this happens and not locked. If on non hd channels, the signal is fine.

jb38: just tried the viewing card and it didn't bring the connection back. I have an old hd box from my old house, do you know if that will work with my viewing card, or would I have to phone sky to link it? If that works then I'd know it was the box.
Thanks again for your help

Jo: The signal on the second input should never be zero at any time, and so try swapping the two input feeds over and see what happens, because what you have reported can indicate either (1) the outlet port on the LNB that's connected into the Sky boxes LNB2 tuner is defective hence try swapping over the inputs, or (2) the boxes actual LNB2 tuner is faulty.

As far as your older Sky HD box is concerned, you could give it a try out using the BBC HD channel and see what comes up, but prior to this check that your subscription Sky viewing card is operating as a standard card on the old HD box by selecting (157) to check that you can view SonyTV, because if you can removing the card should result in the "please insert viewing card" message appearing.

Obviously the best test of all is to try your box out on someone else's twin input dish, but check out that said and give an update on the results.

Jo: Yes please do, but just to clarify on a point concerning your installation, is the Sky+HD box in question an update to an existing one?, or was it installed (by Sky?) as part of a completely new installation including the dish?

By the way, the swapping over of the input feeds test will reveal if the LNB port is faulty or not, because if it is then your normal "non HD" viewing will now be affected, although as things are my main suspicion is with the box.
