What can I do when my Sky Digibox says 'No Signal' or 'Technical fau
How to Reset a Sky Digibox when 'No Signal' appears.
Reset method 1 - Delete and Rescan
- 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.
- 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.
- Check cables and connectors are in good order.
- Wait for at least 30 seconds.
- With the card still out of the machine, plug the Digibox back into the mains.
- Ignore all the messages, and wait for around a minute.
- Try 101 for BBC One, 102 for BBC Two and 103 for ITV-1.
- Insert viewing card, wait a few seconds.
- 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.- 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". - Then press [1] to go to the RF output menu.
- Press [DOWN] three times to highlight the line 22Khz Command and then press [RIGHT] to change the value to [OFF].
- Press [DOWN] and [SELECT] to select Save New Settings.
- Press [SKY].
- Again press [SERVICES], [4], [0], [1], [SELECT]; then [1] again for the LNB Menu. (SERVICES 0 0 1 SELECT for Sky HD).
- Now press the [RED] button (reset all settings), then [DOWN] until you can select Save New Settings again.
- Press [SKY].
Reset Method 3 - Upgrade the system software
If there are still problems:- Turn the Digibox off at the mains again and remove the viewing card.
- Whilst holding down the BACKUP key on the Digibox - NOT ON THE REMOTE - turn the mains power on.
- Keep hold of BACKUP until the screen displays a "UPGRADING SYSTEM SOFTWARE" message ââ¬â this will be white text on a black screen. On some boxes this can appear as a half screen.
- Wait 10 to 20 minutes for the software to download and install. The box will restart when the process is complete.
- Ignore all the messages, and wait for around a minute.
- Try 101 for BBC One, 102 for BBC Two and 103 for ITV-1.
- Insert viewing card, wait a few seconds.
- Check 104 for Channel 4 and 105 for five.

Chris: As this site gives advice on both Satellite as well as Freeview anyone posting a question has to state which mode they are referring to, your particular posting being under the Sky box heading.

Caz: If you have moved a Sky+ box to the other side of the room then unless there was an excess of cable you will have had to extend it using two lengths of coax with "F" connectors on each end and a female "F" back to back coupling piece (x2)to link the extension onto the original cable.
If you have done this then you must have accidentally created a short circuit on the boxes LNB2 link cable as LNB 2 is used mainly for recording purposes, you can soon check if a short does exist or not by swapping the LNB1 & 2 connectors over on the back of the box.
By the way the short will most likely have been caused by a strand of the braiding wire getting wrapped around the middle core of the coax, so unscrew the plug and check this out.

no buddy ,the one in my lounge was taken upstairs and it worked so not the upstairs cabling , the upstairs box did not work upstairs or downstairs and the ex demo /refurb or what ever didn't work upstairs or down stairs either if that makes sense .

michael: Judging by the boxes history and the fact that you see a "no signal" indication even although you know that one is there, points the problem being most likely the usual one of low voltage being supplied to the tuner because of the power units electrolytic capacitors having dried out, this in many cases caused though the box having been previous used in an environment with insufficient ventilation, like enclosed in a cabinet or papers having been kept on top of the box thereby blocking the vents.

michael: Well there are lots of iffy boxes around with faulty power supplies, as although some power unit problems can show up as soon as the box is switched on, on many others it doesn't, and with the fault only showing up after the box has been running about 15 minutes or so, although in many cases longer.
Many of these places that get supplied with a job lot of boxes from retail outlet returns only test the box by giving it a quick power up check, and should it respond immediately gets unplugged again and re-packed for selling on, and so you can see how these problems arise.
