What can I do when my Sky Digibox says 'No Signal' or 'Technical fault'?

What can I do when my Sky Digibox says 'No Signal' or 'Technica

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.

Can anyone suggest a solution to this one? I retained my old working Sky+ box on installing Sky+HD successfully the other day. I registered it with Sky (the viewing card transfer routine)thinking I could later power up the old box and download a couple of recorded programs onto DVD. I am told by Sky that to do that I would need the viewing card - which has now been transferred to the HD box and is unusable for the old box. Has anyone found a way to access the recordings on a non-HD Sky+ box without the viewing card?

I have never had a problem, but suddenly sky news is saying "No Satellite Signal is being received...etc" and then it comes back on again, then goes off again with the same error message "No Satellite Signal....". So I get some Sky News, then nothing, then it comes again etc. Does anyone know why this is happening and how to resolve?

my sky box has no signal what can cause this is it due to the weather with all the snow we are getting I have no response from all reset methods

Saturday 23 March 2013 7:52PM

Frank Hodgkiss: A satellite dishes sole purpose is to collect as much of the signal as it can from the transponder (transmitter) located at approximately 22.000 miles away and focus it on to the surface of the LNB mounted on the end of the arm that comes out from the dish, and so anything on the surface of the dish bowl such as snow etc, will interfere the reflective aspect of the dish, hence will either reduce or completely kill reception.

People with larger dishes suffer do not suffer quite so badly during adverse weather conditions because a higher percentage of the signal is being collected.

Saturday 23 March 2013 8:07PM

Rodney Stone: Basically no, as the process involves code breaking, or at least trying to by using a bench full of equipment.

The reason that your card will not work in the other box is because Sky has programmed the serial number of the new box into the viewing card, and if the card is put into another the box it will not be recognised when interrogated by the card reader, hence access remains blocked to the boxes hard drive.

i have tried all 3 of the above solutions and still not geting any signal,my dish is located at the back of the house.there is no problem with my neighbour signal.

nasim khan: If you are on friendly terms with your neighbour then if would save you a great deal of hassle as far as having to make checks is concerned or carrying out procedures, if you could try your box on their dish, or of course alternatively their box on yours, as that would then give an instant indication as to whether (or not) the problem is being caused by your box or the dish, as it could be either.

I have one of the early Thomson Sky boxes, non HD, which I have just reconnected. No signal. Fault 29. The signal strength and signal quality boxes have nothing in them, and the lock indicator shows "not locked". I have rebooted the software but still nothing. Have checked all connectors and wires (nothing changed) still no signal. Have connected up and old Digitronic box and working OK. Any ideas on resetting sky box? Thank you.
