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.

donald hughes: It would make it somewhat easier for anyone to be able to offer advice if you indicated the type of equipment you are referring to, e.g: a Freesat TV or box, or a normal Sky box / Sky+ / or a Sky+HD type?

Also, if you are referring to a satellite system, then are you using your own dish or are you on a communal dish system?

No signal appears sometimes on 101 102 103 104 but I can then find many other channels, I am receiving signals to my Sky HD + box so what is going on?

It is normally a temporary interruption of either the uplink signal being sent up to the satellite or otherwise a temporary interruption of the downlink signal from the satellite to your dish. As long as you can get other services at the time the 'no Signal' message appears then your equipment does not have any faults. Do nothing apart from checking other programmes can be viewed.
It happens on my Sky + HD pox as well as a Sky + box and at the same time! So it is not something to worry about. Depending on the cause, could be aircraft perhaps, there is nothing the broadcaster can do either. In my experience of satellite broadcasting, going back to 1989, this has happened from time to time.
If your equipment was faulty you are likely to have lost *all* services at the same time.

Hi i have extended my sky cable by 4 meters using conectors to position my tv in another part of the room now i keep getting no signal message. I did a test run a couple of weeks ago and that worked ok but typically now the decorating is done and tv wall mounted in getting no signal issues. Im just in the process of doing a system update but in not holding my breath.
any advice would be appreciated.

jason: Although I wish you good luck with your system updating, but in general terms you should never attempt to carry out a system update if even the slightest suspicion exists that a "no signal" message "might" be connected with work carried out on the coax cables feeding into a Sky box, the danger being that you could possibly end up by corrupting / destroying the boxes software operating system, something which is not recoverable.

By the way, this is partially the reason for the "do not disconnect from the mains or satellite dish" warning.

The disconnecting the box from the mains procedure is however perfectly OK.

Hi, I seem to have the opposite to everyone else - my HD channels are fine but my regular channels suffer from intermittent breakups and no signal banners across the picture. Is this a faulty dish alignment or what?

sarah: Place your box in standby for about 30 seconds before disconnecting it from the mains power supply followed by reconnecting same "after" another 30 secs or so has passed, then once it starts to respond to the remote control allowing it to go its "searching for listings" procedure when hopefully 319 will then be available

It would though have been of assistance if you had indicated the model of Sky box (Sky standard / Sky+ / Sky+HD) you are referring to, as the procedure can vary between models.
