What can I do when my Sky Digibox says 'No Signal' or 'Technical fault'?

What can I do when my Sky Digibox says 'No Signal' or 'Technica

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.

Thanks jb - I called Sky and they are sending an Engineer (couldn't get an appointment till Saturday though which is a bit rubbish). I'll let you know what happens but thanks for your help!

Saturday 25 February 2012 12:33PM

Just to let you know Sky Engineer came today and replaced both input cables as he said there was no signal on one of them. He was not impressed to see joints in the cables near the dish and replaced the whole thing with one piece of twin cable, also giving me more cable at the box end (so I can now pull it right out of the unit!)and making a much tidier job of hiding the cable than before. All seems good now so a very satisfactory outcome all round.

Thanks for the good advice though. This is a most helpful site.

Heather: Thanks for your update on the situation, and pleased to hear that your problems have now been sorted out by the fitting of a new twin cable (referred to as shotgun type) from the dish, also the fact of the cable having been sensibly installed by allowing it to have enough slack to enable the box to be slid out of the cabinet that its housed in.

Regards / jb.

Liaqat £30 for someone to dirve to your house with diesel at £1.41 per lt van insurance, public liability insurance, satellite meter, advertising, tools, van as well, plus his own wage and tax so stop bleating.

I have just upgraded my sky + box to a new hd box, new box installed and working fine. I had a standard sky box in the kitchen which I have taken out and replaced with the sky+ box, I have run a second cable so I have two inputs. The problem is the sky+ box says I have weak or no signal, I have tried connecting the standard box to both cables individualy and it works fine, so I assume cables ok....I then tried the sky+ box back in the lounge and it works fine, sky box ok.... Try back in kitchen weak or no signal... Repeat exchanges still same. Really scratching my head now!!! Any ideas please!

Tuesday 28 February 2012 8:32PM

Eddie: When you ran the extra cable from the quad LNB on the dish are you sure that you didn't accidentally nudge the dish very slightly in the process? as your problem could suggest that happened.

What to do is this, using only the normal Sky box for a test try connecting it to each of the dish feeds one at a time and check what the signal level / quality is indicating (services-4-6) these should be level pegging about 75% or so, if the quality is lagging then the dish is slightly out.

By the way, don't expect to see exactly the same indications on the new box to that of the old one, as the circuitry is different likewise the readings will be too.

Tuesday 28 February 2012 8:33PM

Eddie is the kitchen further away from the dish than the living room, if it is it could be the dish alignment or the dish or even the lnb. Some receivers react differently to weak signal you have done everything you can do the dish could do with being checked on a good meter to check signal strength but most importantly signal quality. Hope this helps

Thanks for the advice, I have run tests, in the kitchen I have used the standard box on cable 1 signal strength 90% quality 50%
Then swaped to cable 2 signal strength 90% quality 50%
In the lounge the hd box gives readings of input 1
Signal strength 75% quality 25%
Input 2 signal strength 60%
So all seems fine?
