What can I do when my Sky Digibox says 'No Signal' or 'Technical fau
Brian Butterworth published on UK Free TV How to Reset a Sky Digibox when 'No Signal' appears.
Reset method 1 - Delete and Rescan
- 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.
- 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.
- Check cables and connectors are in good order.
- Wait for at least 30 seconds.
- With the card still out of the machine, plug the Digibox back into the mains.
- Ignore all the messages, and wait for around a minute.
- Try 101 for BBC One, 102 for BBC Two and 103 for ITV-1.
- Insert viewing card, wait a few seconds.
- 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.- 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".
- Then press [1] to go to the RF output menu.
- Press [DOWN] three times to highlight the line 22Khz Command and then press [RIGHT] to change the value to [OFF].
- Press [DOWN] and [SELECT] to select Save New Settings.
- Press [SKY].
- Again press [SERVICES], [4], [0], [1], [SELECT]; then [1] again for the LNB Menu. (SERVICES 0 0 1 SELECT for Sky HD).
- Now press the [RED] button (reset all settings), then [DOWN] until you can select Save New Settings again.
- Press [SKY].
Reset Method 3 - Upgrade the system software
If there are still problems:- Turn the Digibox off at the mains again and remove the viewing card.
- Whilst holding down the BACKUP key on the Digibox - NOT ON THE REMOTE - turn the mains power on.
- 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.
- Wait 10 to 20 minutes for the software to download and install. The box will restart when the process is complete.
- Ignore all the messages, and wait for around a minute.
- Try 101 for BBC One, 102 for BBC Two and 103 for ITV-1.
- Insert viewing card, wait a few seconds.
- Check 104 for Channel 4 and 105 for five.

Dave if you have taken down the dish and put it up om another house you will find it almost imposable to line it up right you will need to call out a aerial rigger to line it up for you expect to pay around £35

daz evans: It is not necessary to contact Sky or anyone else if it comes to it "if" you align the dish up properly.
As you say you installed the dish yourself, what did you use to set it up? as if as I suspect it might have been one of these simple Sat finders, then whether LED or meter pointer type "slow motion" movements in all operations is the order of the day for success.
Plus the other thing that many make a mistake with, that being, once the satellite is found adjust the pointer / LED indications to show as low as possible, as this makes it easier to detect an increase.

Mazbar: Jb38 i went to a house the other day his dish had been fitted by sky his signal strenght was at 90% but a check of signal quality this was at 10% when i finished his signal strength was at 85% but his quality was 89% on a meter not his box. Signal strength is one thing but if you want a picture that works in poor weather you need a proper meter not a thing with 5 led on them so a small charge to come out is not that bad.

Mazbar -- Agreed - ive seen many a DIY dish installed
Generally its the long suffering wife who has had 3 or 4 weekends ruined by her husband tinkering with the dish and is amazed that I turn up set the ladders up and have it sorted within a 5 mins
Simple -- Pay someone to do a job correctly
I wouldn't install a door frame - im not a carpenter so I get a carpenter in !
The right person for the correct trade
also those little 5 led things- you could be pointing the dish at hotbird or astra 19.8 and they would show a reading in frustration altering it a few mil then checking the receiver - literally could take hours to no avail !

Mazbar: A careful methodical person can set a Sky dish up every bit as good using a simple meter as an Sky engineer or whoever with a £300.00 plus meter, the key word being "methodical", although I would generally always advise them to carry out a signal strength / quality check as a final test, as on average they should see the indications about the same @ 75% minimum, with preferably the quality leading slightly on this, although this not always being achievable depending on the LNB being used, some Sky Zinwell issue sevices having the tendancy of going downhill quality wise on vertical polarisation checks at frequencies above 11Ghz.
Being a long standing RF engineer myself I am well aware of the pitfalls of not aligning things up correctly, irrespective of whether it be a Sky dish or any other type of reception (or transmission) device, but I have to say that over a period of time I have noticed that anyone who asks advice on how to do something (or even just a pointer!) is always being advised by you "not to" and call a rigger or whoever, which, and without by any means wishing to appear offensive, gives me the impression that you are possibly more interested in plugging business rather than genuinely assisting.
I do appreciate the point you are trying to make though, as I am fully aware that there are always a number people about who are inclined to over estimate their abilities, and likewise should really leave certain tasks alone, even for their own safety! but these type of people can very quickly be sussed out as being totally non technically inclined, as and such I would never advise anyone who I would consider comes into that category to try anything other than something relatively simple.

There is a reason for telling people to get a rigger it is one for there own saftey and there own time. By the way what is an rf engineer i have never heared if one of thoese, is it a radio ham like my father inlaw he knows less than he thinks he does. Doing things like tv aerials and satellite it does requier proper equipment and training even the right spanner to tighten up a bolt.

A few years ago I installed a Sky dish myself at my son's house, following instructions from the internet, and using just the signal meter on the box itself (the TV faced away from the window so actually used a mirror ro reflect the screen out of the window where I was up the ladder!). Took me around 30 mins to get the quality over 50% (and it has remained solid ever since) and I was pretty pleased with that, as I have NO skills in this area at all. Would I have rather paid £35 for a professional to do it? You bet! Unfortunately, no-one around here (Ipswich) would have done it for that price, or even double that price : you can count on a minimum £100 call-out, before they even start drilling walls etc etc.
So, my advice would be to get a professional in IF they'll stick a dish up and connect it for, say, under £50 (or if you want it somewhere awkward or dangerous to get to), BUT if it looks easily accessible and you have a neighbour's dish as a 'guide' (and you've made sure you've got clear line of sight, obviously), then it's not that hard to do.

Hi dale you are right i wouldn't call simeone out for thst price but here in the north west a call out charge is £25 to line up a sat it is about £35 and to fit it from scratch it is about £50 i even supply and fit the dish with a run of shotgun coax for £89 and i am quiet expencive for around here.

I installed my First satellite dish on an my mums garden wall on an old analogue sky box i could see the tv from where i stood and it didn't take too long- yes if your methodical go ahead have a go - what were talking about though i suppose is the people who have had a go and have spent several weekends "having a go" - im losing sight of those people who have had a go and have got it right so yes - by all means go for it if you want - ive got to say for a line up I charge £45 if its local to me - Dale £100 just for a call out is in my opinion over the top
JB 34 - A question if you will
I have been called to look at a farm house where the customer is having trouble with receiving some music channels 4 music kiss and a few others ive narrowed it down to transponder 40 which is high up the sat band at 12480.00 MHZ
looking at the signal from the dish comes in at 77 db
the installer has used rg6 from the dish to the loft dont think its a long run as it loses 1db but he has then used sky wf63 through the loft and down to the lounge when its in the lounge its about 60db and there is a distinct slope from the left side of my analyser to the right where this mux is - I installed a new dish as the signal was low -this is before I tested the signal at the sat box end and realised that there were 2 joins in the cable - sorry did I not mention that the cable comes into the lounge at a back box with a blanking plate with a join behind it down to a outlet plate - the reason I assume is that the cable installer didn't know what height the customer wanted the receiver at
now--- the LNB is a Zinwell - I was going to go and try some line amps in the loft to see if that cured it - some vision ones I picked up from solutions
I have run a ct 100 direct from the dish to the receiver just to test the run was about 15 meters straight from dish to lounge - absolutely no break up on the channels - and the customer absolutely does not want any cables run externally as I know re running ct 100 from dish to receiver is a perfect cure but he has spent thousands renovating this property
So question is - do you think the line amps would work - do I need to change to a different manufacturer of LNB or even resort to putting a 60cm dish up
What would any of you professionals advise in this situation ?

Kb the two joins are the one's you can see. If the coax is in the walls could the plasterer have nicked the coax. You will have changed the joins for f conectors back to backs. Is the loss at the first join if it is the problem is between the loft and the first join. No help but to say to the customer that if he wants good signal the coax needs changing. You say 60 db loss is quality ok if it is the 20db in line amp might help but this will insert noise and that could be worse.
