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.

angie: a bit more information would be useful...we may be good but not mind readers! Where are you, what size dish do you have, LNB, receiver, whats the on screen message on BBC1 or BBC2, can you get ITV1,2,3,4?

In some north eastern areas of spain an 80cm satellite dish will do, in others a 2.4m dish is required!

a few things to try
unplugging the box wait for 30 seconds and reboot it.
go to the menu system and reduced the time for "instant rewind" or turn it off altogether.
I only notice a slight delay when going to HD channels, maybe somethng to do with the amount of data HD channels use

Any help with this would be greatly appreciated:

My sky keeps cutting out repeatedly, the picture jumps about and then "No Satellite Signal is being received" comes up, then it goes back to working fine for a few minutes and the whole things repeats again. Eventually it just won't show any picture at all (just the error 29 message). The picture might come back later on but sometimes it doesn't, no idea what to do, tried all three above methods. Thought it did work after the 3rd one, it worked perfectly for about 10mins but then it just cut out again.

Really stuck as to what could be causing this, any advice would be great thanks!

Daniel - This could be (A) Suspect conection at either the receiver end or the LNB where water ingress in the cabling may be the problem. (B) Your dish requires re-configuration to peak the signal (C) Faulty PSU - power supply unit in the receiver. This applies particularly to Thomson boxes and some others where the capacitors are failing.

Christine - SKY receivers that are faulty will be repaired or replaced by SKY during the 12month intitial subscription period. Not all receivers (They are Manufactured by different suppliers.)- although they look alike are prone to PSU failure. I am aware of subscribers having receiver swop overs outside the initial contract period without a call out charge, but this seems discretionary usually when subscription termination is being muted by the subscriber.

P>S SKY also offer (It costs though) a scheme that covers equipment replacement receiver-LNB-cabling and I have known some that have benefitted from this.

hi ive just connected my sky hd to a new hd ready television model hitachi L42VCO4U B ive connected it using the HDMI lead. my previous tv used a scart. heres my problem the sky box searches for chanels doesnt find any and then says no signal. swithed on and off tried using scart leads followed your steps on searching for an up grade and tried method 2 but still no joy. i dont have an aeriel attatched to the property so could it be due to the television not being installed as that also says no signal. really thought it would work as my last tv to huge and ugly worked fine
