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.

Dale: Although as MikeP has suggested the problem certainly seems to be caused by a software issue, however on checking back postings I dont see you having mentioned the exact model number of the Sky box in question, therefore purely out of curiosity I would be interested to know what's printed on the ID plate?

My previous research/testing has proved useless anyway : yesterday the box was on 998 when I took it out of standby in the morning, despite only recording one thing overnight ; and again later in the day despite no recordings ; but after recording 2 sets of 2 channels together in the evening, it then correctly went back to Ch 141 where it had been left. Back to the drawing board.

Can you check whether you're mains supply is not having temporary outages? That may only seem like a brief flicker of the lights (if they are of the incandescent type) but may be enough to make the box briefly go off and then it will come back on 998. Apart from that idea I'm now struggling to understand what may be causing it.

No problem with the mains : when you check the relevant screen it says it has been connected for a number of days. Also, have not had any interrupted recordings. Funnily enough, it has remained on Ch 141 (BBC 1 HD) ever since I last posted, despite numerous single and double recordings.

my sky+ box has no signal of any kind. When I checked signal all boxes are blank and two says null. Is this a harddrive problem?

anne: Its extremely difficult for anyone to offer advice with such a limited amount of information being given, however if you have your own dish then it might have been accidentally knocked out of alignment, but should you be connected into a communal dish system then check with a neighbour to find out if they are being similarly affected.

You should also try swapping the two input input feeds (LNB1 / LNB2) over and see if this restores reception, if it does then there is a defect on the cable going into LNB2's input.

By the way, the problem is not connected to the hard drive.
