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.

I brought out my sky+ box to Spain. Unfortuanately there is,no input cable from a sat. dish. The system apart from telling me I had no signal indicated that I may be able to watch programs I had previously recorded. I can't. The box sits on the 'search for listings' screen. Can you confirm that I can or cannot watch these recorded programs without an input from a dish. I have it connected to broadband but the same applies,

Thanks and regards,

Hi bill

The sky box needs a signal from a dish to enable the operation of recorded program playback

Good morning,Skybox reception of BBC and most other channels,apart from Sky specific ones, is intermittent and fragmented,Freeview, via aerial reception,is fine.Is this a transmission or connection problem?
With thanks.

Denis: Although it would have been of assistance to know which model of Sky box you are referring to, however, carry out a signal test check on the box viewing the strength and quality indications for about a minute or so, should rapid fluctuations in the quality be seen then this is inclined to point to either a bad connection in one of the two "F" connectors, or alternatively that water has crept into the connector screwed into the LNB.

Needless to say, this should be removed from the LNB, followed by further unscrewing from the coax cable to enable it to be checked out.

By the way, should you be referring to a Sky+ box? try swapping the two LNB input feeds over, if the problem vanishes then fault is on the cable presently connected into the LNB2 socket, as normal viewing is via the LNB1 input.

alan hammond: sounds like your dish got moved by the wind you need to get the dish re aligned back to sky to get signal back. sky will charge you £80 to fix it

alan hammond: Although Rob is quite correct in what he has said, but should you be able to access your dish go into your Sky boxes signal test screen and check if anything is being indicated, which it might well be if the dish is only a fraction out, as the "no signal" warning jumps in at a threshold level which is quite a bit above an absolute zero signal.

If anything is indicated, usually with the quality of being much lower than the strength, try pressing the dish on the extreme left hand side and note the result, should this action make the situation worse then the dish must have been moved in the other direction, however it the situation improves then slacken the horizontal clamp bolts and reposition the dish for best quality.

By the way, when dishes are moved by the wind its nearly always in the horizontal (left / right) plane.
