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.

Sarah C: That error code simply indicates that the box is unable to receive the default transponder, this providing the EPG programme guide.

Have you tried swapping the two inputs from the dish over? because "if" the LNB1 input has developed a fault, e.g: by water having entered the dishes LNB "F" connector, then the action of swapping them over will return normal viewing, but though with the faulty input now being on LNB2 will stop you recording, as LNB2 is mainly used for that purpose.

paul: Not quite sure what you mean by Freeview being from the same dish? as Freeview is terrestrial based service received via a normal aerial.

However, if you have a Sky+ HD box as well as having another Sky box then you obviously have a quad block fitted to your dish, but though if neither box is receiving a signal then this has to be caused by the dish having been knocked slightly out of alignment no matter what it might look like, because even the most experienced of dish installers would not be able to tell if the dish was bang on alignment or not, as you are only only referring to minute differences.

On the normal Sky box, if you press on "services - 4 - 6" then do you see anything being indicated?

My Sky HD box started recoreding some things but not others. So I switched the power off and done a reboot. Now all a get is the No Signal message. I have tried many reboots twice I have had the Sky Intro channel playing but when I try another channel it say No signal again. Ive contacted sky, not much help, checked the cables, swopped them over, tried a different HDMI cable to connect it to the TV, but still nothing, Any Suggestions?

Sean Connelly: A no signal warning does not always necessarily indicate that nothing at all is being received, and so there is always the possibility that a signal is being picked up but not at a level high enough for the receiver to decode, hence its ignored.

You should carry out a signal check using the following procedure:

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

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

3:- Use the left / right arrows to scroll to "Signal" and press select, the the grey bars displayed will show you the strength of the anything that might be received.

If you do see anything indicated then the strength / quality levels being indicated for both tuners have to be around 55% minimum or more to produce a picture, because if its significantly less than this then it points to the dish being slightly out of alignment.

Hi! I've done steps 1,2 and am now doing step 3 to reprogram my freesat box. I have been waiting more than 45 mins for the box to turn itself back on (the red light is still on) What do I do now? Is it still reprogramming? I'm totally not techno savvy!

Pearl: Open the rear cover on your remote control and rotate each of the two batteries by about half a turn just in case they have developed a bad connection, should this action not make any difference to the situation then disconnect you Sky box from the mains supply "after" having left it in standby for about 30 seconds or so beforehand followed by waiting another 30 seconds before reconnecting it again, then once it starts to respond to the remote control allowing it to go through the usual searching for listings procedure.
