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.

seanw: You should check out the signal strength / quality indications seen by pressing "services - 4 - 6", both S/Q should be roughly level at about 75% of the way along, as although the box is possibly faulty what you report is in most cases caused by the dish out of alignment.

seanw: Well, I have never seen 100% strength being indicated on a Sky box! still what you have reported doesn't really suggest the dish is the problem, albeit that the quality should always be level or slightly above the strength indicated.

If the engineer is coming on Tuesday there isn't really any point in trying anything else, and you just repeat to the engineer what you have said in your posting as he will carry out his own checks anyway.

It would have been interesting though to know what manufacturers name was printed on the underside of the box. (paper label)

hi,box is a panasonic,funny thing is when i went to check the box and moved the cable on the back,ie the arieal cable,the screen lost signal,i re tightend the cable and it came back,maybe its as simple as that,but i have checked this before,and i still cannot figure why some channels are effected but not others,signal strength as always been 100,sometimes you can see the quality bar move down to60/65,then back up to 75/80

seanw: I would, with the box off, remove about 2cm from the end of the satellite input, and then carefully remake the end.

When you reconnect, ensure that all of the outer strands are touching the screw connector and none of them the inner.

I live in Belvedere in Kent. I had a similar problems with my box recently. I used all the reset methods and I got to say after using method three everything seems a okay so far. I'll monitor the situation.
