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.

Maria: The only test you can try which will give a 100% accurate to where the problem is located is by trying the box with the problem in the Sk+ boxes position using any one of the two "F" plug connectors transferred over from the Sky box, as they are identical to each other.

If the box still doesnt work then its the box at fault, but if it does then its either a cable / "F" connector problem at the box end, or alternatively the connector on the LNB or indeed the port used on the LNB, which wouldn't really be a problem as the LNB should have another outlet thats unused so the connector can be transferred over to it.

Thanks so much will give all of those a go. We don't owe the box anything it is probably 15yrs old so can't complain!
Once again thanks for the advice

After receiving a SK+HD box, I connected my old sky+ box in another room, and connected 2 more cables to my dish. But my old sky+ box says no signal being received. I have 2 cables running from dish to this box, and when i check signal test there is no signal and both show as not locked.
I have tried both cables in a really old standard sky box, and they both work fine as a freeview box and gets signal.
Please help. Parish

Parish: You only really have one test left to carry out, being to couple the old Sky+ box back onto the two dish feeds used by your new box, as if you find that it still doesnt work then the old Sky box has failed after having been disconnected from the mains.

This is something that can happen with electronic devices that are generally powered up all the time thereby being at the same temperature, then are allowed to cool down by being unpowered, this even being a test used to detect intermittent faults on integrated circuits etc, e.g: alternate use of a hot air blower and a freezer aerosol.

The fault is most likely in the power supply.

laura: If there is any snow on your dish, clean it off. Take care not to move the dish's position.

sadekali: PARAS - Professional Aerial Riggers Against The Sharks has some thoughts on who to contact if a communal aerial or satellite system isn't working. The first person to ask, if you're not sure, is whoever you're paying rent to.

emily: Assuming you are referring to a Sky+ box which has two "F" connectors, and if so then what you say suggests that one of them is not connecting properly, so try swapping the "F" plugs over and see if the fault transfers to the other input, if it does then carefully unscrew the "F" plug from the cable on the one with no signal and check that a single strand of wire hasn't wrapped itself around the copper inner core of the cable.
