Hi,I have Freeview via a BT Vision digibox, which has received ALL available channels with good reception since installation in August 2007.
During the previous two weeks, several channels have started to continually freeze / pixelate / breakup or fail to display a picture altogether. I have checked the
DTT Signal via the TV settings menu, and it appears that it is all TV channels using Carrier channel'746 Mhz' (inc UKTV History, Virgin 1, ITV2+1, Film 4), and tend to be worse at night.
Signal Strength = 21-26% (fluctuating)
Signal Quality = 25-35% (fluctuating).
All other Carrier channels (that are still working ok) show....
Signal Strength = 25-31% (stable)
Signal Quality = 100% (stable).
I have rescanned / re-loaded several times with no success, and no hardware / connectivity has been disturbed prior to the problem.
Have you any ideas please?
Thank you, Mike.
Mike: I'm sorry but I can't really help without your full postcode. Sally9022Monday 28 January 2008 4:22PM
I know this sounds daft, but, Channel 4 on my t.v. seems to be digital! As all my other channels are 4:3 aspect, and when a film was shown on channel 4(forest gump on sat evening) and the adverts finished, the film restarted, and the image switched to widescreen!!??
I live in the scottish borders in the TD8 area Near Jedburgh.
Please help, I think i may be going loopy!!Sally9022: Channel 4 is the only UK broadcaster to use a widescreen signal on the analogue transmissions. It is part of a defunct PAL+ standard, which some TVs (usually Sony) silently support. This is an analogue service.

I have moved from England back to Scotland. I still have ITV West ON MY SKY BOX, How can I get STV? or what is the Frequencies for STV GlynSunday 2 March 2008 7:39PM
Mansfield I am receiving freeview in the central area, but I am receiveing local programmes from the Yorkshire region. I would like to know how I can receive news & programmes from the Central region please? Do I need to change the frequencies? If so, where can I find them? Also, I am on a communal aerial, would this need to be adjusted?
ThanksMatthewThursday 27 March 2008 5:10PM
our tv isnt working and was just wondering if it is the transmitter for the lancaster area is down,
could you please tell me if the information is correct.Matthew: The transmitter is back up. If you are missing the channels now, please rescan for channels. Jon: Nothing is reported. Loss of all channels is usually a cable or connector failure. JonThursday 27 March 2008 9:07PM
Thanks for reply. I know 5 other people in the area with the same problem. We are all in the same boat. Cant pick up any BBC, ITV, C4 or C% using just the arial. And nothing at all using our freeview boxes. Who would I report it too as I think it must be the main transmitter at fault. ThanksMACCAThursday 27 March 2008 11:57PM
Hey, i met someone from this forum,,,,it was good that our transmitter in lancaster whent down,,,,,,strange how and where you meet people,,,,,hope this is the beginning of something good,,,,,,thanks rob mcewen from morecambe for telling me about this forum,,,she sounds a great lassJon: Where are you? Can you tell me your postcode please? JonFriday 28 March 2008 8:31AM
Bournemouth I'm BH4 8EU one of my friends is in BH8 who has the same problems. ThanksJonFriday 28 March 2008 8:34AM
It seems to be widespread across the BH area. I reckon that its not been widely reported as you wouldnt know about the problem if you receive signal via a sky dishJonFriday 28 March 2008 6:53PM
I have freeview but have disconnected it to reset it. I've tried just using the standard arial but cant get the normal channels through that. Have just reconnected the freeview box and it still finds no channels and my friends have tried the same with the same resultJonFriday 28 March 2008 6:59PM
Bournemouth I'm closest to the Rowridge transmitter and the arial is pointing toward it. Until Tuesday I was receiving Freeview and normal BBC etc through the arialjonFriday 28 March 2008 9:07PM
Bournemouth Thats right I have neither, the freeview box can be found on the normal tv channel. However when it searches it can find no channels at all. Its the same problem with my friendsjonFriday 28 March 2008 10:30PM
Bournemouth Ha ha ha ha! I've tried the ariel wire and a coat hanger!Trevor BailetSunday 6 April 2008 4:14PM
Swansea I have been receiving freeview perfectly well for some time. Now it has all stopped - No Signal ! What has happened?

Only recently I haven't been able to receive a signal from my bbc 1 or 2 channels it constantly jumps and gives a headache if you try and watch it. No problems with any other channels but its getting worse. I have an outside ariel fitted and digital in built in our tvs please can you tell me what is causing this weakness. Trevor Bailet: Loss of all services will indcate that you have a failure - either the aerial has been damaged or a connector is disconnected or cable has a problem. Sometimes people find that a tree coming into leaf between the aerial and transmitter is the problem, but it is usually a poor connector, cable or a moved aerial.

Bristol my post code is BS9 4PQ,
Having recently obtained a TV receiver with built in freeview, I found that although BBC channels were OK, the ITV channels were breaking up.
I replaced the aerial with an 18 element wide band aerial and a loft amplifier which improved the situation but the picture still breaks up occasionally. My pocket scanner shows a hefty signal being received on the Kings Weston channels.
Looking at the terrestial analogue picture intermittent white dashes of interference appear particularly in the area of channels 40 - 50. As I live within shouting distance of Southmead police and Fire stations and Southmead hospital, could this be interference generated from Tetra transmissions. If so what can I do about it.Mike Austin: TETRA transmitters can be a problem... The booster will simply amplify this interference, so you need to use a rooftop aerial with a masthead amplifier. If you use an aerial with more elements, they are more directional and can help with TETRA type interference. jayne eamesFriday 11 April 2008 10:25PM
Petersfield i was having problems with channel 5,qvc bid up tv,five setana,five us. i am on the midhurst transmitter at first the channels were slow to lock up, so i did a auto tune and now they no longer tune in. I checked to see if there is a problem with transmitter and it is saying that it has low signal. How long will it be before it gets better.my post code is gu31 5lq jayne earnes: The signals will be improved at switchover, but without your postcode I can't tell when that would be. The signals have been at these levels for the last nine years... terry reynoldsThursday 1 May 2008 8:21AM
could you please tell me the frequency number for central news birmingham at 6pm mon to friharry o hare: We find out tomorrow...! henry smithSunday 25 May 2008 12:41PM

(weve just moved in and the anolouge reception with the grid aerial is fine - even bbc 1 and bbc 2 . )henrySunday 25 May 2008 12:46PM
Oldham sorry - i dont know where that maps come from - mine is 0l3 6eehenry smith: Grid aerials are not suitable for Freeview reception. DaveSaturday 7 June 2008 6:26PM
Gloucester Dave.
I live in Huntley in the forest of Dean, my closest TX is Ridge Hill, but due to a very large hill and a big tree
I can`t pick it up. I have re-aligned the wide band aerial to mendip some 75km away as the crow flies.The problem is I can`t get BBC1 or BBC2. I can get all the other channels all 56 fine at strength 9, is BBC1&2 on it`s own mux or is it with other channels? Has any one got any ideas, I live in a bungelow will that make a difference?davidMonday 16 June 2008 12:46PM
when the digital switchover happens will the current analogue channels be turned into freeview MUX frequencies giving freeview an extra30 channels or so??david: No they won't they are being sold by Ofcom to the highest bidder. I'm just writing an article about that very subject. Michael CaseThursday 19 June 2008 11:26PM

Mr Mick CartwrightSunday 22 June 2008 10:12AM
Dudley Any ideas whats gone wrong? I have a freeview box echostar T-101 which until I did an update channel search a couple of days ago worked absolutely fine with all available channels coming up ok and with their correct allocated channel numbers.
Now I find that the following channels have changed their Nos to:-
800 chl 4+1,801 E4,802 ITV3,805 ITV2,
807 CHL4,808 ITV4,809 MORE4,810 ITV1,
812 BBC1,813 BBC2,814 BBC3815 BBC NEWS,
816 BBCi,817 CBBC.
After trying several updates,they still remain the same.
My post code is dy2 9nf and my aerial is facing our local transmitter at Brierley Hill in the West Midlands.
Is it the box that is now not compatable?or is it an alteration from the transmitter causing the problem?
Any help much appreciated.
regards Mick cartwright

Altrincham Please help!!! Just lost 60+ digital channels after 6 months great reception, from my Toshiba 40" TV. Still getting 29 digital channels but have lost ITV 1, ITV2, ITV3, ITV4, Channel 4, channel 5 etc. It is difficult to understand when the reception has been so good for 6 months. The channels I receive are very clear and I had a new digital ariel fitted before having the new equipment set up. Why some and not others?
Please help.mick cartwrightTuesday 24 June 2008 7:54AM
Dudley Thanks for suggestion,tried poweroff/no aerial connection,power back on and did re-scan "came up no programmes found"
Re-inserted aerial and re-scanned again,came up exactly the same as before with incorrect programme Nos.
Any other suggestions/ideas appreciated. mick cartwright: The receiver should only allocate numbers in the higher range if there are already channels on the correct number. If the above procedure did not work to delete these channels, then you need to look in the menus for a "reset box to factory settings" and have another go at rescanning.

Good Afternoon
We live just outside of Faversham in Kent and since last week, we have no signal at all (you can hear the sound, but vision is horrible).(This is anolog) We have a Sony With build in Freeview, and tested with another television just to make sure it might not be the TV but no luck. There is no digital reception at all, We do have a booster and tested that to ensure that it might not have failed etc. But nothing at all. And currently at the point where it is just the singal. We have no idea what could have caused it, Any advise would be appriciated. Thank you very muchTraceyTuesday 9 September 2008 2:10PM
I live in the Galmpton Area Nr Brixham. Since the end of August 08 we are experiencing problems with a majority of our channels, the BBC channels seem ok at present, we've had no signal for ch5/fiver/five us, itv1,2,3, ch4, ch4+1, e4,e4+1, sky 3, etc - we briefly get the itv/ch4 channels for a very short time then it switches off again - and has been off the majority of the time and the anologue transmition is poor. We are coming up to 2 years at christmas in having the digital tv and dvd and havent experienced any problems with transmition until now. how long before we get any of these channels back. post code tq5 opq
