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.

Hi, I have been receiving Freeview through my old Sky box withought any problems for a while. Just recently I got hold of a Sky HD box that can record. When I swithch this off at the wall, the only way I can get this to work again is to disconnect the cable leading from the dish to input 2 and put it back in again. This ususally gets the box working again but this is a pain. Is there something I can do to get over this problem otherwise I will have to revert back to my old box without record facility?

Hi, I hope you can help, but this may be outside your remit. I have aSamsung HDSKY/DIR made in 2008. THere is a problem with remote control operation. The box will accept a random number of commands, and then ignores a random number. The remote has been replaced with a brand new original and the problem persists. Could this be a software problem?

THanks in anticipation Mike Costello

Well... after last month's experience I had when I tried to fix a poor signal and ended up with none at all.... I bought a second hand box and tried again.
I went through the steps above, but it too is registering no signal.

Could it be that when I did the test on the old one, a surge of power knocked out the receiver on the dish ... or something????

Tomy Hall - a satellite transmission wouldn't be alocalised event if there was a problem then the whole of the country would have no reception - and I reckon that if sky wasnt transmitting then that would make national news headline - not that you would be aware as you can't watch tv! (sorry couldn't resist)

2 possible faults




test your receiver on another dish --- or test someone elses receiver on your dish to work out which part is the problem

if its the dish - call someone in - you don't want to attempt to sort it your self as its on a roof there are massive health and safety implications (as Rod Hull found out for a very short few seconds)

if its the receiver get it repaired or buy yourself a cheap £30 freesat box from argos if your only using it for free to air reception as that would be cheaper than repairing a sky receiver and you get a 12 month guarantee

alter the hd output you have several choices

start at 576i and work up

your tv might not cope with the higher resoloutions

leave it on the highest that works

I have had Sky for about three years. It is in a room with no telephone connection. The Sky box has worked all the time with no telephone connection. Now its not working and when I check via System Test it says telephone line not connected.
Any Ideas please?
