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.

Jay: OK. Three possibilities.

1 your sky box recover circuits have broken

2 your dish has moved

3 the lnb has failed

Jay: Thank you B. 1. What can I do to test this in such case. would i need to get a new box? Mine is an old version, but appears to be in good condition as i don't move it around at all. 2. Perhaps with all the wind and rain over the previous weeks dish could have moved, but its been through worse and still functioned? 3. How can i check the lnb's failure?

Jay: if you can borrow a working sky or freesat box, this would help you work out if the problem is the lnb, or the set to box.

The dish isn't likely to move by itself but it could have been hit by something...

Jay: Just some additional information to add to that already said by Briantist.

The message you see is generated internally within the box and that's why its so clear, but as far as older boxes are concerned these can suffer from power unit failures resulting in the "no signal" warning being triggered even although all is OK with the feed from the dish.

But though "if" by any chance the replacement box also shows the no signal warning then "at the dish end" unscrew the gland nut that holds the "F" connector into the LNB followed by unscrewing the connectors body from the coax and checking same for any traces of water, very common on older installations!, should any be found dry it with a tissue then smear the inside of the connectors body (where coax enters) with some Vaseline, (should really be silicone grease!) followed by screwing the connector back onto the coax but AFTER having first ensured that all strands of the coax braiding are pulled back over its outer cover.

This procedure might not be required, but mentioned just in case!!

g sarjantson: Yes, but you will have to go into the set up menu and select "single input operation" to combine the two tuners.

However, single input operation limits your recording possibilities to only being able to record programmes that are transmitted on the same polarity to that you might happen to be viewing and which could be on either vertical or horizontal polarity, because if you try to record a programme that happens to be on the opposite polarity a "not possible" or similar warning will appear.

I have been having this no signal message on both my sky HD boxes since last Thursday morning. I have tried every tip I can find and nothing sorts the problem. What is really strange is that if I connect any of the dish feeders to my smart tv wich has an inbuilt freesat tuner this works fine

Stephen Darch: Although you may well witness a "no signal" warning on your Sky HD boxes this does not necessarily indicate that nothing is being received, and so you should carry out a signal check using the following procedure:

Press "Services" on your Sky remote control and you will see the main menu with "Options" being highlighted.

2:- Select the "Settings" menu using the right arrow button and press select.

3:- Use the left / right arrows to scroll to "Signal" and then press select, the grey bars displayed will show you the strength and quality of the signal being received.

Should anything be indicated then the strength / quality levels seen have to be around 50% minimum to produce a picture, this especially so where the quality is concerned which should never be lower than the strength, because if it is then this points to the dish being slightly out of alignment.

Thanks for your reply I have checked this and there is no indication on input 1 or 2 hence the confusion as when I attach the feeder to the smart tv I get a great freesat pic with no problems
