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.

I have a quad LNB that had 1 spare connection, the other 3 were used for the sky+ box and freesat for the TV which are all in the main room and work fine. I want to put in a sky box in the bedroom so have run a cable from the spare connection on the lnb into the bedroom, fitted f plugs and tested with the sky box from the main room, I keep getting no satellite signal, thinking I might have moved dish I took the sky box back to the main room and it works fine. Any pointers to what the problem could be.

Nitin Tejura: This problem can only really be caused by two possible reasons, being either a strand of wire has accidentally wrapped itself around the middle core when you were fitting the "F" plugs, or that the spare port used on the LNB is defective, as if the cable was new its extremely unlikely that it would be defective, so take each of the "F" plugs off in turn and carefully inspect that the aforementioned possibility hasn't happened.

Before you do this though, you should try one of the other boxes on the newly run feed, which of course should not work.

By the way, you wont have accidentally moved the dish if any of the other boxes still work, although when carrying out tests like that you should always use the same channel, as if the dish was a fraction out its sometimes possible for one channel to work whereas another wont.

Just bought Sony Bravia tv with only 1 scart socket ( my previous Sony had an integral freeview that couldnt cope with the now required re-tune). I have 2 sources previously both connected by scart that I wish to connect. A DVD player and home cinema/surround sound ( a Sony compact av dav-S550). Neither have HDMI. DVD player has optical socket and scart. The surround sound has scart, optical digital in,and various video component sockets in/out. TV has component in and optical out sockets

Any advice on how to connect up the system would be appreciated

Many thanks

Depends if you have a twin feed back to the distribution switch if yes then yes if you have a single feed then you can watch and record but not 2 channels at same time if you don't have a feed to the distribution switch then no - and usually a bedroom isn't wired back to the switch its wired so you can view the lounge box in the bedroom using rf2

Pleased to say that on Thursday 22nd March 2012 my Meridian S E just returned to my SKY box. At least one thing I learned from this was how to install other ITV stations!

lee townend: A fault of that nature can only be caused by something concerning your installation, are you sure that nothing has happened with your dish? although another aspect could also apply, being that if your box has been running for a lengthy period of time (weeks) before being unpowered then sometimes they can develop a fault on cooling down whereby something will blow on switch on.

Can you see the menu screen? and if you can press services - 4 - 6 and see if the signal indicators are completely blank or are showing a very low level of signal.

Hi we have a communal dish with no analogue service. No grey bars for signal strength or quality.
Have carried out all the usual checks by ourselves and with the sky help desk.
Spoke to the management company for the building on the two occasions(neighbours have also complained), the attitude we are getting is 'not our problem'
Thank you for any assistance could either be a private repair or DIY.

The no signal strength happened suddenly five days ago, with no problem with weather, scaffolding or any new build.

Thanks again for the assistance
