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.

as long as its not your dish at fault you can get a standard definition FREESAT box from argos for £30 that would take place of your sky box

Neil - sat dish might need re aligning

haven't a clue what the high pitch sound was unless it was the power supply dying

Mark - I think you have exhausted your DIY capabilities im afraid - without the correct equipment lining a dish up can be done but is not the easiest thing todo - will give you an example
a friend of mine owns a plot of land in france and has tried for over a year in varying weather and sheer frustration moving the dish millimetres at a time with no success

I turn up for a holiday with my £300 Horizon hdsm meter and have it lined up within 2 mins

Bite the bullet and get a local professional in to line the dish up for you -- one thing I will ask is --- Is there anything in the way - has a tree grown that little bit more and is now blocking the signal ?

Expect to pay a local rigger £45- £65 to line a dish up that is on a standard wall - expect to pay more if the dish is on a roof/chimney

ben: This usually means the dish is aligned to a satellite, just not the right one.

Ben there are umpteen satellites in whats called the Clarke Belt
your satellite dish can point to any one of these satellites some are stronger than others in britain - but your sky dish can pick up a signal from popular satellites like SKY 28.2 ° East or 19.2°east - the angle of the dish isn't far so if you have tried to re align your dish using the signal strength meter it is not un common to line up on the wrong satellite !

TRy moving the dishto the left a bit till the signal strength goes up again - hopefully you will get the lock message next time

or - get someone out to line it up for you

Evad: Try rebooting the SkyHD box. Switch off the power, and leave it for a few seconds. Then press and hold the "back up" botton on the box, and keep holding this down while you switch the mains power to the box on. Keep holding down the "back up" button until all four LEDs light on the front of the box (can take 15 seconds or so). At this stage, you can release the "back up" button - you should see a message on the screen saying Software Update - do not switch off - may take up to 10 minutes. Leave the box to complete this reboot. After it has finished (and a short delay) the box will typically show a "Sky HD please wait...." message on the screen. Leave it alone whilst this is on. After it has disappeared, the box will go into standby - and then you should be able to power it up.
Occasionally this has to be done a couple of times.
