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.

Bryan Grozier: Access to the card slot on a Sky+HD box is via a drop down flap located on the front lower right hand side of the box.

mary rose lomas: In most cases (but not all) this is caused by the dish having been accidentally moved very sightly by for example being blown by a particularly strong wind or knocked against by a ball or similar.

Press "services - 4 - 6" and check what the indications are, as both should be about 60% plus, if both or one is under this then the dish is out of alignment.

I am using FreeSat over here in Germany and I have 100% signal and 100% signal quality.

But since yesterday I can not get channel5 and some other channels.

BBC and all the other channels still have 100% on both counts.

Does anyone know what the reason might be?

Thanks for your help

Tom: Try a "Freesat" re-tune - three additional channels were added yesterday i.e Challenge TV Pick TV and Sky News and that maybe related. Worth checking out especially as your getting 100% signal and PQ.

My Freeview box stopped working after the digital switchover here in NI. I live somewhere with a dish on the roof and a satellite plug on the wall so I have been attempting to install Freesat. I have tried a couple of different (basic) boxes now and I can't get all the channels that I usually watch. The signal strength is very good - comes up at 100% - but I can't receive channel 4 (but have channel 4 + 1) or any of the other channels on the same frequency. Any suggestions. About to give up and return to Freeview!

Dear Sir,
for some reason my sky+ box picks up certain channels ok but, with others I cannot get a signal. For example I can pick up most of the free to air channels but not film 4? I have another digibox in another room which works off the same dish and that picks up film 4 fine and all the other channels. Any thoughts please?
