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.

My elderly father has a satellite which i think 'looks' (is that the correct term) at Hotbird. He gets Polish TV from it. Recently his picture has gone to black & white even though his ordinary TV is still colour.

Any ideas as to what may be wrong?

Thanks

Mike

mike dow: The two most likey reasons are:

1) The SCART cable is loose; or

2) The output has been changed from RGB to SVideo in the menu of the satellite receiver.

Maxine: Mounting the dish up higher to avoid the trees is the best option.

hi there, I have a sky box that is used only for freeview now, as no longer a sky customer. It has alternated between very good and broken up picture quality. Now I have absolutely nothing for two days. I live in West Sussex, my daughter lives in Surrey and says that her tv is also behaving in the same manner (she also has a sky box). At present the weather is very windy here and I wonder if this is the problem affecting my tv set and her and probably many others in the area

hi, i have tried all 3 methods above twice but no luck. we've had really bad winds and rain all day (60/70mph) and a power cut, so could it be the dish moved or box damaged? are either easily fixed or do i need an engineer?

thanks.

kitty: If you have tried all three methods at the top of the page with no success, then you probably have a cable, LNB or dish fault that will require an engineer to fix.

It could also be a be a fault with the Sky box, but this is less likley.

Loveday: If "Method 2" does not clear the problem, you probably need to have an engineer change the LNB on your dish as shows signs of failing.

Hey man,

I have a sky box that has always lost channels. If I reset the box, they'd come back. But within an hour or so, the channel is hard to get back. I have to change then channel and cross my fingers that when I return, the channel will appear.

I'm going to try your methods. Any thoughts?
