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.

Siobhan:
In the past, I have seen that you can record and not play back if your card has not been paired correctly by sky to the box.
If you get Sky Sports, or get the upgrade message, then the card should be paired and working. If you get "wrong card" then the pairing has not been done.

It may also help if you do either a planner rebuild (like a PC defrag), or a full system reset (ie full format of the hard drive - you will lose your recordings with this).

It may be that the hard drive has gone and a replacement is required.

We suddenly have lost certain channels and only receive there is a "no signal" error whilst strangely a lot of other channels are still there.Why could this be?

Marcus:
UK TV comes from 4 satellites, each with their own characteristics and footprints, and the channels are apread over various frequencies on these 4 satellites. Thats why you can get Sky News on an small (60-80cm) dish all over spain, but need a 2.4m dish for some areas for BBC1&2.

On my sky + box I have lost sky 1, channel 5, sky sports news and various other 'sky' chanells - can still get 1,2,3,4 sky news, dave etc. Have checked dish, lnb, done all resets, health checks etc but still nothing sometimes its just blue screen, other times its 'no sat signal' other times it comes on then picture freezes. Tried my old sky box in its place this morning and everything works fine. Got to be a dodgy box??

Tony: Yes, that does sound very much like the Sky+ box has a fault.

Jan: That usually happens when you create a "SCART loop". You only need to connect a SCART from the Sky box's SCART socket marked "TV" to the TV and the SCART marked "VCR" to the DVD player.

If you also connect the DVD to the TV, you will see the problem you have.
