Euronews on 204 on freesat is missing today
I've done a retune but it hasn't returned. Other channels are all there
I can also get freeview, and euronews isn't there either
Did a retune and now cannot get sky news
Seems to be only 79 channels
Help!

Oh dear. You have done the one thing you must never ever do first when you lose channels, retune. That must never ever be the first thing you do, it should always be the very last option once you have eliminated every other possible cause of the loss. Now you will have no idea if you have found and fixed the true reason why the channel is missing.

On Freeview have you also lost channels such as Pick, Really and Dave? If so then you have lost the entire mux carrying those channels plus Sky News. If you do get those channels but not Sky News then there is something odd going on.

The reason for losing a mux could be a fault with the aerial, cabling, connectors, interference from somewhere or even transmitter work. So you need to check out as much as possible of your system for problems. But as I have said now you've lost the tuning data for some channels you won't know if anything you do has restored them unless you continuously retune to see if they return. Which of course carries the danger that whatever you do could lose even more channels. Now you know why you should never retune first!

And is Euronews even on Freeview? It's not listed here

Unless it is a streamed service?

No I haven't got pick, Dave etc now
In the past whenever I'm missing a channel I've done a retune and its restored it
The advice given online is to retune, so how could I know you shouldn't do it
What do I do to restore these channels
Also why has Euronews disappeared from freesat?

The advice to retune when a channel is lost is basically wrong. Because there are many and varied causes why a channel can go missing and all of those must be eliminated first before you contemplate retuning. About the only time a retune is the option of first resort is if the channel concerned has moved from one mux to another. But usually such moves are advertised well in advance and often accompanied by on screen messages.

As I posted you need to check out as much as possible of your aerial system as you can get at safely to see if there are any faults that could be causing the loss of channel.

For example a loft mounted aerial can be subject to all sorts of reflections bouncing around inside the loft which can interact in unpredictable ways. Moving stuff about, adding stuff to or removing stuff from the loft can change all this and cause a previously working set up to stop working properly.

For an outdoor aerial a neighbour erecting scaffolding nearby can have a similar effect. As can a new building either blocking the direct signal or generating reflections causing interference to the direct signal.

Cable problems can cause odd effects. I've even known kinks in a cable act like a filter attenuating certain frequencies. Poor connections can also have an effect. And a split in the insulation on an outdoor run can let rainwater in degrading the cable.

It has been reported several times here on DS that getting the aerial lead coiled up with other cables (HDMI leads especially) can cause issues. More so if the cables are poorly made with inadequate screening. Some cheap and nasty supermarket aerial leads are especially bad at rejecting interference.

There could even be work going on at the transmitter. If you know which transmitter you are on there may be a note about it here

But essentially unless you have a TV or PVR that you know works and receives all channels OK, (and of course is tuned to the same transmitter), that you can borrow to check your aerial/cabling etc. or you can tune your TV in on a known working aerial, you will have to risk checking the aerial etc and correcting any faults found then retune the TV to see what effect it has had. Hoping that the "fix" hasn't made things worse.

As for Euronews not being on Freesat. it is not listed on the Freesat channel list

http://cdn.freesat.co.uk/freesat/fre...022%202016.pdf

That has nothing listed for channel 204. So maybe it has ceased being available on the Freesat EPG?

Well, we must have been lucky then, as up to last night we got Euronews on 204 and have done so for a long time!
The freeview arial is in the loft
No one goes in there, there is no storage, so it is never disturbed
Nothing has changed with the cables etc
Just looked online, and on sept 22 it states Euronews is on 204, yet on another list of channels on freesat , 204 is missing!
What's going on
Plus, can I restore missing channels in freeview?

It may be that Euronews is no longer on the Freesat EPG but is still broadcasting on the same satellite transponder. So, until you retuned, your Freesat box still retained the relevant tuning data to find it. But once you retuned it was wiped from the list. You might be able to get it back in non-Freesat mode if it is still broadcasting and you can find the relevant details to feed into your box.

As for Freeview. As I said you need to make sure everything is healthy with your aerial system then attempt a retune. That is the only way you will get the Freeview channels back. You can reduce the risk of messing up any other channels by doing a manual tune on the mux carrying Sky News etc if your TV has that option. All you need to know is the UHF channel number for the mux on whatever transmitter you are receiving from.

If you are not sure about the transmitter stuff your postcode and house number into the Checker on www.digitaluk.co.uk and tick the Detailed View box. This will show your most likely transmitter. The number in the dark grey column under the ARQ A header is the UHF channel you need.

I did this
The number was 48
I went into manual tune
It said no channels memorised
What now?
By the way, freesat said Euro news had chosen to remove itself

for people who lost think you can still view it here

if its the right channel though its better on freesat than on line.

What transmitter did DigitalUK say you are receiving from? Sometimes the one it says should be your most likely transmitter isn't the one you are actually getting.

On some TVs you can get it to tell you what UHF channels it is using. If you can find this information you can compare it to the list on DigitalUK and double check you've got the right transmitter.

One other thing to check. When you go into Manual tune do you get the option to select DVB-T and DVB-T2 (if you have a Freeview HD TV). If so make sure it's on DVB-T.

If everything appears correct then either that mux is off or there is some reception problem preventing you receiving it. On my TV it shows a signal strength meter when you dial in the UHF channel number. If yours does the same and you get no or very low strength indicated that would explain why it's not getting anything.

Emley moor transmitter
Reception is good and I should get 113 channels apparently
No option to select dvbt etc
The thing is I did have all these channels
It's only since this morning I retuned and only got 69 channels, so there isn't a problem with reception normally
I'm loathe to mess with it as I don't want to make things worse, and I'm not paying a load out for a tv engineer
Probably the best thing is to do a complete reinstall but I can't see the option to do it.
Also I have CCTV through the TVs and don't want to do anything to mess it up

How is the CCTV connected? If it uses an RF link via the aerial input on the TV then that might be causing problems. If however it is connected via an AV or HDMI input then it shouldn't affect anything.

If it is connected via the aerial socket on the TV then disconnect it and plug the aerial direct to the TV and try again. If you now get the channels back then the problem is the CCTV system.

Similarly if you have anything like a Sky box or PVR that the aerial passes through disconnect them and plug the aerial direct to the TV.

If the cable from the aerial ends up on a wall plate with a short link cable from that to the TV try a different link cable.

I really don't want to mess about with it myself, and get into further problems, especially where CCTV is concerned as its so important
I'll try and get someone who knows what they're doing!
Thanks for your help
