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.

michael: Have a look at the rear of the box and give an update on the details printed on the label, and especially the brand model as it can be either Pace or Samsung, however although it should not be necessary to do this but you should carry out an LNB check, this done by following the undermentioned procedure "if" your box uses the updated menu system.

LNB checking - reset on a Sky HD box

1:- Press services on your Sky remote control and you will see the main menu with "Options" highlighted.
2:- Highlight the "Settings" menu using the right arrow button and press select.
3:- Press "0 - 1 - Select" to access the Installer setup menu (this menu is not listed on the Settings menu options).
4:- Press Select to see the Setup menu displayed with Hi and Lo band frequencies indicated.

The correct LNB values should read:

LNB Type: Standard
1:- Low Band LO Frequency: 9.75
2:- High Band LO Frequency:10.60
3:- LNB Power Supply: ON
4:- 22 KHz Command: ON
5:- Single feed mode normally off.

Press the red button to reset them to default values even although they may
already be indicating them.

michael: Meant also to say that whilst in the installers menu check the "default transponders" settings as this has to be correct, if not this will result in the "no signal" warning.

Default transponder: 11.778GHz
Polarity: V
Symbol rate: 27.5
FEC: 2/3

michael: Really pleased to hear that you are now operational, although as aforementioned in my previous reply it should not have been necessary to carry out that procedure if the box had been tested on a Sky signal prior to packaging, as its not a setting that can be lost by unplugging, no matter for what period of time.

michael: I did wonder when you had made reference to your "old" box, however, and as previously requested, could you please supply the details seen printed on the rear label of the recently acquired box (brand - model number etc) as this will give me an idea of the menu system used.

Another aspect that I had meant to mention is whether or not you are using a single coax feed to supply the box? as if you are then this has to be connected into the boxes LNB (1) input followed by going into the installers menu (services: 0-0-1-select) and turn the single feed facility on.

With regards to the default transponder info given on the previous posting, have you as yet checked this setting on the problem box? then after having done so typed in 998 the Sky guide channel, that is if the box failed to select it automatically.

Finally and just out of curiosity, but does the source that you purchased these boxes from also sell brand new boxes? or are they restricted to only selling refurbished types?

I have a Humax Freeview Box, connected to an LG TV, It has been fine up until about a week ago. No Signal, is shown, then picture is back with no sound, & sometimes whole screen is coloured Green, no Sound or Picture, Have tried switching off overnight, next morning working normally again. So frustrating! Living in Melcombe Regis Weymouth. Confused Pensioner.

Audrey: If you have the Humax box coupled into the TV using a scart lead then check to make sure the the connector plugs at both ends of the cable are fully seated into the scart sockets, as if not this can cause the problem mentioned.

However this would "not" be the cause of the "no signal" warning and which could indicate a problem with the box, as a while back a number of Humax boxes developed this problem although its my belief that the models affected were connected into the TV via an HDMI lead and not a scart, and so if the scart socket check proves to be negative maybe you could indicate the model of box in question, and whether or not a scart or HDMI connection is being used.
