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.

KB Aerials / Mazbar: The set up instructions suggest to me that the RF channel changing is achieved on the Global device using exactly the same coding line that was previously fed into the Sky boxes internal modulator, in other words just as if the Sky boxes RF modulator had been removed from the box and positioned externally but with its data control line still being sourced from exactly the same circuitry within the box but via the IO port.

I see that Amazon would appear to have been advertising these units specifically for use with multi-room boxes as seen on the undermentioned link.

Lynne: If you are connected to a communal dish then the problem is either being caused by a defective jumper lead from your box to the wall plate, or alternatively an actual fault within the Sky box itself, because other than that the problem is outwith your control.

Try swapping the two dish input feeds over and see if this makes any difference, although if it does then the problem will have transferred into the recording side of the box, but though if no difference was noticed then this is inclined to indicate a problem on the dish feed to your apartment as each apartment will have its own individual dish feed albeit via a switching device.

As jb said if no one eles is experiencing the problem then its likely to be your equipment at fault

Can you test your sky box on a friends dish to eliminate one or the other
If the problem presents its self at thr second dish then its your receiver or the cables leading back to the outlet plate

Or - and its unlikely the outlet plate is faulty

It could be yhe piwer supply within yhe sky box over heating
Try cooling the box if you have a desk fan try poinying it at the back of the sky box and see if the issue calms down

dave bambrough: If you are using a twin tuner Freesat PVR or Sky+ box then try swapping the two LNB inputs over and check if the quality returns.

If though you are only using a single input receiver then unplug it from the mains for 30 seconds or so before reconnecting it again and checking the results once that the programmes channels have loaded back in again.

Should it still the same then your problem might possibly be caused by water having entered the LNB's "F" connector, and so this should be unscrewed from the LNB (by only turning the gland nut) then further unscrewed from the coax for checking, once done having ensured that all strands of the braiding have been pulled back over the cables outer cover before screwing the connector back onto the coax.

You could of course bypass having to carry out those checks should you be friendly with anyone who would allow you to test your box out on their dish system, because boxes do go faulty.

dave bambrough: sorted the problem. turned out to be dish alignment. the holes for the bolts eroded so the dish has slipped down. relocated dish and realigned. took some time but got there in the end

dave bambrough: Thanks for the update and pleased to see you have managed to rectify your satellite reception problem, dish alignment generally being the last thing I mention until all other avenues have been checked, this simply being due to the fact that most people are unable to carry out any form of remedial action where it involves adjustments having to be made to the dish, but though with yourself obviously being an exception to this rule!!

Have you taken any further action with regards to your Freeview problem?

Hi there hoping someone can help. I've got a Thomson HD box which only shows signal and quality for input 1. Input 2 is at a constant zero unless I swap the cables round, at which point input 1 drops off and input 2 has full strength and quality.

I've tried the usual fixes so far of new LNB and new cabling but both haven't fixed the problem. Thinking it may be the PSU failing, but not sure if my symptoms point towards this as input 2 does come back online when the cable is swapped. Keeping the box turned off overnight to see if it works any better when completely cool (another tip from researching), but not hopeful as I've had the box off previously. Any help is greatly appreciated.
