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.

ITV1 Central South is on 11973 V 27.5 2/3 - sky card required
ITV1 Central East is on 11973 V 27.5 2/3 - sky card required
ITV1 Central West is on 10758 V 22 5/6
ITV1 Central South West is on 12420 V 27.5 2/3 - sky card required.

Although these may change frequencies when if / when the sky card versions move to Astra 1n, the new satellite for 28 east...

Sat and PC guy would carl have to add these channels through the add channels feature of the sky box or are they available already on a specific channel number ?

I have a sky box and use the analogue out cable to serve a splitter in my loft, and then on to other tellies. Consequently I can get sky on channel 35 on all tellies. Everything is great except that BBC1 and BBC2 on the digital channel (not sky, or analogue) don't work. All other digital channels are fine. It's just BBC 1 and 2. If I plug the TV aerial straight into the splitter it's fine. Any ideas?

Kev - its likely that your sky output is wiping the signal - what transmitter are you on?
alter the rf output of your sky box to another channel and retune the other tv's in the house to sky - you should find that the multiplex you wiped out now works!

Shaun make sure the feed from the sky dish isnt shorted

a single strand of outer braid touching the inner core will do this
unscrew the connector fold back the outer braid look real close as a single strand wrapped around the inner core is easy to miss


If not maybe there is another problem with the cable
from the dish to the receiver

P.T.White - Check the cable connection to the receiver to make sure it's sound and hasn't loosened. - If that's sound and still no signal your dish may have moved off signal or the receiver may have a fault. You can check the receiver if you can connect to another dish through a relative or friend. If it that's OK then your left with the probality of a problem at the dish end either through movement of dish - cabling issue or faulty LNB.
