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.

Mike: As far as your Freesat question is concerned nothing requires to be altered, as both systems are totally compatible with each other as far as the dish is concerned.

I would suggest though that albeit a bother to do, but you should temporarily try the upstairs box in the downstairs position to see if the problem follows it, because if you say that the signal strength / quality appears to be OK then its the only way of determining whether the intermittent problem is being caused by the box, or alternatively by the upstairs connection to the dish, or even the LNB port being used on it.

I have the latest sky + HD box and have 2 other tv's in other rooms but not sky multiroom. I also use a surge protector where my cables are plugged into.I removed the cables from the surge protector to put them all in a "cable tidy" then fastened them back into the surge protector and the main tv is ok but when i turn on the other 2 tv's ( one in bedroom, one in dining room )all i get is message saying " no signal " and i cant get anything from either of them.

Steve: Assuming that the two other TV's are being used to view Sky via your Sky+ boxes RF1(or 2) output, although this shouldn't really be necessary as nothing should have changed, but go into the Sky boxes set up menu (0-0-1-select in one smooth operation) and make sure the RF output channel is still set to whatever it was before, as what you have reported suggests that it possibly isn't, this happening when you disconnected the box from the mains.

This said though taking it that you haven't accidentally left the co-ax cable from the Sky+ box unconnected, but there isn't really any connection between your cable tidying up exercise and not being able to receive on the other TV's except by the possibility of one of the aforementioned reasons applying, unless the boxes RF modulator has failed. (not unheard of!)

By the way, if you have forgotten which RF channel was being used by the Sky boxes modulator just carry out a re-scan on one of the TV's whilst its on "analogue" and it will pick it up, then do likewise on the second set, if you experience interference on the TV's you will need to set the Sky boxes modulator to another channel and set the TV's to this, or just re-scan the TV's again to pick it up.

steve: When you went into the section of the Sky boxes set up menu referred to did you see "RF output" mentioned on the list? because on re-reading your posting I see you mention that its the "latest" Sky+ boxes you have, and if its a DRX595 model then they do not have RF modulators fitted to them.

To be able to use the RF feed through to TV's in other rooms you would require to purchase a separate RF modulator, this connected into the Sky boxes scart socket, devices such as this sold by Maplin.

Am i the only one here who thinks Sky's service is pretty disgusting.
I origionaly had a Panasonic TU-DSB30 box when i started my subscrition.This worked great until around 2005 when it started missing channels or havingto go through CH5 to get to BBC2.I found out this was a Panasonic box fault and fitted a Panafilter which cured that but on using the reboot suggested at the time made the box lose neary all stations or state 'no signal being recieved'.This box i now have with a cooling fan and panafilter fitted but it's useless andat my expense.
I then decided to go for a Panasonic TU-DSB50 to replace it with (used one, as i love the sound and picture quality plus speedy system) as this was always highly praised.It started off fine but now i keep losing certain channels....... (BBC2,Movies4men,Horror,PickTV, Sonytv amongst others).I have tried most things suggestedby the many sites NONE have cured the issues.
I bought a secong Panasonic TU-DSB50 ,this one is EVEN WORSE.
What gives?
Freeview is far more consistent.
If it IS the manufatcurer of the boxes how can they justify this poor effort?
Panasonic are a very good brand (or so i thought).
Maybe i should upgrade the basic cable i had when it was installed.
The signal rating is very good,about three quarters for both signals.
Any help appreciated otherwise i'll give up using Sky's system altogether it's too much stress and agro.The reciever box relibailty is appaling too.

I am having problems with my Sky multiroom second box. It was having the signal interrupted so I was losing recordings. I have been through all 3 of the procedures above(twice) and have now lost BBC1/2, ITV, Ch4/5 thogh the rest of the Sky channels seem fine. Any assistance would be most gratefully received.

Have cabled up the spare 4th LNB socket to a working satellite receiver and am getting "No signal 29" error. The other 3 LNB sockets all work fine, do I need to reset something or change any settings on the Sky system to get the 4th LNB socket to provide a signal, thanks?
