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.

Living in Rhu, Helensburgh G84 8SY about 40 miles west of Glasgow. All signals disappeared at about 10.10 today and have not yet returned. Any info?

Peter Corbett: If your problem is with Freeview the BBC reception report currently shows the Rosneath transmitter to be off the air from 10.05 this morning - 12th May 2012. Additionally BBC National DAB radio is shown as very weak signal from Rosneath from 10.06.

I tried all your processes to reset my lnb and still doesn't work still get no signal messages.
My Sky was working fine up until today and for the last 5years.
We had a huge wind storm here in Portugal and I think either has moved the dish or the lnb has broken down. I asked for a technician and they want 125 call out to look at it and then they will probably charge me the rest for a new lnb can not afford this at the moment. How easy is it to buy a new lnb and fit it myself or do I need a special signal machine? I just do not get any grey bars at the moment when making a signal test! Gutted!

Massimiliano: Judging by what you have said I suspect that its much more likely that the dish has moved slightly rather than the LNB having developed a fault, as the dish only needs to move the mearest fraction to knock the signal out.

You should press "services" then 4-6 and check the signal strength / quality thats shown on the two indicator bars (if any shown) then if you know the direction that the wind was blowing give either the left or right hand side of the dish a knock checking the result on the TV screen, as with a bit of luck you might be able to knock it back into alignment again.

franky vaughan: Taking it that you are referring to a "Freesat" twin channel PVR recorder? if one of the feeds from the dish gives a good signal on LNB 1's input but the other gives no signal on the LNB 2 input then swap the two input feeds over and see if the fault changes positions, if it does then you should check that the "F" connector on the "no signal" input isn't shorting inside because a strand of wire is touching the inner core, if though its found not to be then couple it back into the box again as its time to move outside to check that the "F" connectors on the other end of the cable havent became waterlogged and is shorting out, if though nothing appears amiss then swap the "F" plugs over again but this time on the LNB and have a check on the recorder, if you see that the fault has reverted back to its original position then the block is faulty.
