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.

Andy: Taking it that you have verified that the sat box you are using on that outlet is OK, then I would unscrew each "F" connector in turn and check to make sure that a single strand of the braiding hasn't shorted onto the inner lead, or if you have an ohms checker just try that across the plug making sure that the meter is set to its lowest ohms range or you might get a false reading. (nothing should be indicated)

Admittedly the No4 outlet on the LNB could possibly be faulty, but its extremely unusual for this to happen.

Neil Morgan: Try swapping the two rear "F" connectors over to see if you can still receive BBC OK by doing that.

Ok so I get the message on my screen saying 'No satelite signal being received', or just stays stuck on "Searching for listings, please wait' - I have an Amstrad Sky+ box. We also have another box exactly the same and a HD box in the living room, both are working fine.

Ive tried all the above 3 methods, plus have swapped the cables around at the back (the white ones from the dish) and still isnt working.

What can I do?

I have Sky multimroom with 1 HD box and 1 Sky plus Box. Since the storms which havn't been that bad for me (Herts) I have lost all signal on input 1 for both boxes.

I have powered off the LNB and done a LNB reset, but no difference. I haven't yet reset the digibox given both are effected.

Could I have a damaged dish or LNB. Nothing is visually damaged

Danny W: Its extremely unlikely that anything had changed except for the possibility that your dish (or LNB fixing) has been very slightly knocked out of alignment, and a difference that's so slight that no-one, even an engineer, could possibly notice on looking at the dish.

Just to exclude the possibility of any surge having done a mischief to your box (unlikely as it is) swap the "F" inputs plugs over and see if input No1 starts working again, albeit No2 possibly wont!
