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.

Paul: If you have double checked that the "F" connectors on the original cable are still OK, then your problem is likely to have been caused by dish having moved slightly whilst you were working on the LNB, as the movement necessary to kill the signal is so fractional that it cant even be noticed by a trained eye.

If you can access the dish whilst viewing the TV screen, leaving it sitting on the signal warning screen then slowly press the left hand edge of the dish watching for any signs of the message breaking up, which it would do on the detection of a signal, if nothing is seen then carry out this action on the other edge of the dish, as when dish alignment is disturbed its usually in the left / right horizontal plane.

Martin: Which type of HD box are you referring to, Freesat or Freeview?, and have you tried retuning the box since "plumbing" it in?. Also, is the aerial or dish that the box is connected into known to be OK or not? by having been used by another device prior to you trying the HD box out on it.

I have done all the mentioned resets with no luck, my sky+ box has updated so I'm assuming that I'm getting a signal but still get the error msg saying I'm not. Is there a way to confirm I'm getting a signal.

Many thanks


P's can you email me direct if possible.

Sean Shortland: Try swapping the LNB inputs over and see if this changes anything, because if the coax feeding into the boxes LNB1 input is defective this will result in a "no signal" message being seen.

I have an old, bog standard Sky box with a magic eye in my bedroom straight above. From time to time I become unable to change channels, in fact my remote control doesn't work at all upstairs. I can watch the channel that was last on downstairs but am unable to change channel, change volume etc The light has gone out on my magic eye but it was off even when the remote was working. Can anyone help please? Thanks!

mark688: Does the situation regarding the signals on the ports change if you swap the boxes LNB1 & 2 inputs over? The other point being, that if the two ports you refer to are on a Sky+ box then the signal levels on the check screen should never vanish no matter what channel you choose, as these level indications only represent the default transponder.

Further advice dependant on the outcome of the above mentioned test.

Gail: Try connecting your magic eye directly into the Sky boxes RF2 socket and see if it lights or not, if it still fails to light then either the eye is defective or its the Sky box.

But though, its best to check that the RF2 socket on the Sky box is still powered, the procedure for checking being to press "services - 4 then 0-1-select" and this will take you into the installers menu, select and press on RF outlet.

You should also check that the batteries in the remote control are OK.
