Dusica: If my memory serves me correctly on that model you should be able to manually install channels under the "Installation / Service set up / Manual install service" menu.
However I would recommend that you carry out a factory reset first then followed by an auto-tune, this achieved by holding down the Menu button on the side (or top) of the TV (not remote) for about 5 seconds or so until a menu appears, then carry out steps 1-5 as though you were first installing the set.

I have a tesco technika tv with built in freeview and now have to re-tune it every time it's turned on. Any suggestions how I can solve this please?!jb38Thursday 1 December 2011 8:24AM
Jenny: The usual reason for this happening is because more channels are being picked up than the memory is capable of storing, hence when the set is switched off they get lost.
You have to carry out a factory re-set first (sometimes called default setting) then cary out a normal auto tune.

King's Lynn My mother has had a Freeview aerial installed, procured a FV TV but now cannot get BBC's Look East and instead is only able to access BBC's Look North, a regional program not orientated to her location in NW Norfolk. Can anyone advise what can be done to resolve this? Thanks in anticipationIan: Your mother's TV is obviously picking up Belmont's signal.
Run the auto-setup scan with the aerial unplugged and then plug it in when it gets to 25%. Phil BurtWednesday 7 December 2011 10:15PM
Gillingham I live in Gillingham Kent and I have just brought a new TV, the house hasn't had a decent TV at all and found that the current arial wasn't working, so brought a new digital one with a mast amplifier. The house has also just been rewired with a labgear amp and splitter. The problem is that I can only get the 7 BBC channels or sometimes 17 channels that include the 'adult' ones!. On checking the area via TV, it is showing either London ID305 of Kent, also the power amp bit makes it worse! Any ideas anyone? Phil BurtWednesday 7 December 2011 10:30PM
Gillingham Phil Burt: sorry that post should have said it is either showing London ID305 OR KentTravis HeskethFriday 9 December 2011 6:36PM

London Hi I have a Freeview TV in the bedroom but it does not pick up any Channels. When I first installed it it picked up everything but gradually all stations have disappered and when I try retuning it says no services are found. Any suggestions?? On analogue it picks up two stations and they are very fuzzyGARY MILLMANThursday 5 January 2012 9:18PM
panasonic th-42pz80ba tuning problems.
Everytime I switch the tv on it has to be retuned from scratch. I have done the factory re-set and then auto tune,and the software is upto date.ChloeSunday 5 February 2012 1:12AM
Hi, I have a JVC tv in my bedroom and have recently tuned in to receive digital, which is built I (I never used this before as it was connected to a sky box.
Every time I turn the tv off and back on again, I have to retune it all as it loses all the channels. My tv downstairs works fine so I know it isn't an aerial problem. I have tried restoring to factory settings but this doesn't work.
Please can't anyone help? Thanks!jb38Sunday 5 February 2012 9:27AM
Chloe: Without knowing the model number of the JVC TV, but if after having re-tuned and you selected to store the channels found, as this is not done automatically on every device, and yet you have lost them again after having switched the TV off completely then that's inclined to point to a fault in the tuners memory chip.
This said taking it that you genuinely carried out a factory reset, as this fault is usually always caused by the TV having picked up more channels than its memory can store hence they are lost on switch off, and if you have already carried out the reset then there isn't anything else you can do.
Just as a test though, carry out a re-tune without the aerial connected, then after re-connecting again give the set a second scan. Mike RobsonWednesday 8 February 2012 11:30AM
I've just retuned my freeview box so as to be able to receive the BBC channels, which have altered. However, having done this, the BBC News Channel now automatically reverts to BBC1. How do I get the News Channel to stay there ?RodSunday 11 March 2012 1:38PM
Hi just bought a new DVB-T receiver and connected all up switched on got great reception but only can get BBC channels cannot get any ITV etc we are OAP so any help will be appreciated thanksRod - have you had a digital receiver before or is this your first one ? - possibly need an aerial upgrade - I know this is vague but without knowing more its difficult to say - without putting some test equipment to see what the signal strength is like

Sutton Coldfield my tevion 19"has lost channels 3,4,5,6,8,and reprograming them does not bring them backjb38Sunday 11 March 2012 11:11PM
kev askey: As you are virtually the next door neighbour to Sutton Coldfields mast try taking the aerial out of the TV and carrying out a re-scan with only a short (about 12" or so) piece of wire inserted into the inner part of the aerial socket and see what transpires, or better still a set top aerial should you have access to one.
What model of Tevion do you have? I live in north somerset and cant pick up ITV west on my goodmans tv anymore, I can only pick up the Welsh programmes. Ive tried to auto tune but can only get 83% and then it stops. Ive tried tuning manually but its just not picking up the wests channels. Seems I can get all the 'adult' ones I dont want but not the ones I do want!!! S Williams: Try running the automatic tuning scan with the aerial unplugged up until 63%. You may have to manually add C48 for ITV3 etc. I receive my TV signals from Rowridge which is reported to have no known problems and should now be transmitting four HD channels.
I have retuned two HD TV's and a BT Vision box none of which find the HD transmissions which I believe should be on CH 50,51,52 & 54.
Is there a problem at Rowridge ? toddSunday 1 April 2012 11:40AM
Trying to install an aerial in the loft of my house. However i cannot get a signal at all. Even though an indoor aerial downstairs gets a signal. Please help. I am using a high gain wide band aerial from b n q. Trying to point at the belmont transmitter from great gonerby.
todd: Having tuned the set in that you're using when setting up your aerial, check that it is tuned to Belmont for all its channels and not another station such as Waltham which would appear to be very strong in Great Gonerby.
For each of the following, check the signal strength screen and ensure that it is tuned to Belmont:
BBC One = C22
ITV1 = C25
BBC One HD = C28
ITV3 = C30
Pick TV = C53
Yesterday = C60
You should not have Waltham whose channels are:
BBC One = C61
ITV1 = C54
BBC One HD = C58
ITV3 = C29
Pick TV = C56
Yesterday = C57
Try pointing the aerial in the direction of Belmont from a first floor window.
Maybe the roof tiles are affecting the signal too much. I read on here comments about some modern tiles having greater metallic content which inhibits signals. jb38Sunday 1 April 2012 4:48PM
todd: If you are located on the top of Gonerby Road hill or even on the down side of it provided its the side leading to the Downtown store, then you should have no problems whatsoever receiving Belmont, if though you are on the South side of the hill leading towards Grantham then you could experience problems in some areas around there, albeit Waltham is OK.

Christchurch Hi I live in Christchurch and appear to be having problems receiving any channels that are (Or should be) broadcast on ARQ A and ARQ B, IS anyone else having these problems or can they suggest a solution, everything was OK before we went full digital.
ThanksMRW: The transmission power of the Commercial multiplexes from Rowridge, which include ArqA and ArqB, will increase on 18th April.
I am note sure whether there were any changes to ArqA and ArqB that would have been to your detriment that took place on 21st March.
There is probably little you can do in the mean time as well as little point as the situation will change on 18th April. kevinMonday 9 April 2012 2:50PM
hi im in the carshalton area/ ive retune my freeveiw but lose bbc2 and other bbc channels after a very short period,i beleive im receiving from crystal palaceWendy LeakThursday 12 April 2012 5:03PM
Grantham Hi, I own a Humax Digital Recorder HDR-FOX T2, however, since the 2011 retunes in my area (Postcode NG31 7FJ, Waltham transmitter) reception on the Humax Freeview unit hasn’t been very good. The Humax unit worked perfectly well up until last year’s retunes with good reception on all channels but since then the reception on various channels (including QVC, Yesterday and Channel 5 + 1 to name a few) is terrible with the picture and sound breaking up. Sometimes the picture is so bad it’s unwatchable and I often receive a screen message saying there is nothing being broadcast on the channel or it’s being scrambled. (I also own a Samsung DVD Recorder which is connected to the same TV and reception on ALL channels is good. My aerial is approximately 3 years’ old and is fitted with a booster.) Unfortunately I’m not very technical so please can you offer some advice. I look forward to hearing from you. Many thanks & kind regards,
Wendy Leak jb38Thursday 12 April 2012 8:48PM
Wendy Leak: Auto-tuning a box in the Grantham area can result in a mixture of Belmont and Waltham being picked up, and so you have to ensure that the three correct commercial transmitters have been picked up.
To do this select EPG 10 (ITV3) and then carry out a signal strength (condition) test whilst on it this done via the tuning menu, although its not so much the signal strength you are interested in but the transmitter channel number associated with the indication and which should be Ch29.
Once done go back out of the screen then select EPG 11 (Pick TV) and carry out exactly the same procedure as before, but this time you should see Ch56.
Repeat this entire procedure again after selecting EPG 12 (Yesterday) and in this case Ch57 should be seen.
Try this and give an update on results, as if these numbers arent seen then the box will have picked up Belmont, so you will require to manually tune them in to get Waltham.
jb38Thursday 12 April 2012 9:06PM
Wendy Leak: Just a minor alteration to what I mentioned, to find out what the transmitter channel number is whilst on the any of the EPG numbers mentioned, do it by going into: Menu - settings - system - signal detection and you will see the actual transmitter channel on the right hand side of the bar.

Maidenhead I use 'normal' tv channels via an aerial when I am recording satellite channels (or record from 'normal' channels while watching something else on Sky). I had BBC1/2, ITV, C4 and C5 but recently I've lost BBC2. Does anyone know what channel I should be using (autotune doesn't find it) for BBC2 in Maidenhead (postcode SL6)? Thanks. Abby: By "normal" I assume you are referring to analogue as you only make mention of the five channels available in analogue.
The first stage of switchover at the Crystal Palace transmitter happened on 4th April when BBC Two analogue was switched off. Tonight the rest will go. So if your TV does not have a digital (Freeview) tuner built in, then you will need a separate set-top box. HelenWednesday 18 April 2012 6:21PM
Hi, do you know if my flip down under counter kitchen TV which is analogue can be adapted or is it totally obsolete now, I suspect it is?susanWednesday 18 April 2012 8:58PM
I have a mikomi tv. No freebies. Can't seem to find any channelssusan: No very much to go on there... We would probably need to know your postcode and where your aerial is located. KMJ,DerbyThursday 19 April 2012 1:57AM
Helen: Any TV can be adapted to receive digital signals. If the TV has a scart socket it is just a matter of connecting a freeview box to the TV with a scart lead. If this is not possible you will have to receive an analogue signal via the aerial socket on the TV. To supply the analogue signal it is necessary to use a Freeview box with a built in modulator (or a Sky box or a VCR which also have a modulator built in). Of course, if you decided to use a Sky box it would have to be connected to a satellite dish, whereas a Freeview box would use the aerial which used to provide your analogue channels.Ed StockingsThursday 19 April 2012 9:40AM
Buntingford My aerial is pointed at Crystal Palace. After the 18th April re-tune, my PSB3 HD signal is STILL coming from Sandy Heath - like it did pre DSO (even though I'm pointing at CP). How can this be so, when Crystal has increased the signal to a whopping 200Kw? (I live in Buntingford, Herts.)KMJ,DerbyThursday 19 April 2012 10:50AM
Ed Stockings: There are several reasons why Sandy Heath could be selected in preference to CP for your PSB3 mux. Firstly, it is found first in the scan being on the lowest frequency. Secondly, depending on the type of aerial in use and local reception conditions, it could be the strongest signal arriving at your tuner. As you say, CP is 200kW but is 59km away, SH is 180kW at 25km, making SH the stronger signal before terrain and receiving aerial characteristics are taken into account. The Digital UK postcode checker predicts that reception is better from Sandy Heath at your location. If you require the Crystal Palace signal to be tuned in, rather than SH it will be necessary to do a manual tune on C30 after having either deleted the data for C21 or clearing the whole channel list. I assume that you selected "London" if you were presented with a choice of regions when tuning.Mike DimmickThursday 19 April 2012 12:38PM
Ed Stockings: Despite the current UK spec saying that the best transmitter should be tuned in, some HD boxes still do it the stupid way, selecting the first version found when scanning. Complain to the manufacturer (my guess is it's a Humax?)
You may also find that you're getting D3&4 (i.e. ITV1, C4, C5 and associated channels) from Sandy Heath rather than Crystal Palace, as this transmits on C24 from SH compared to C26 at CP.
A manual retune is the only way to ensure you're getting the services you do want. If it's still flaky after doing that, check for too much signal.EstherFriday 20 April 2012 9:49PM
Hi,
I live very close to Crystal Palace. Until 18 April I used to receive a very good signal quality with all channels. Since the switch over, I have lost most of them, ie ITV3, etc.
I still have strong signal with other channels as BBC. I have tried to retune the box several times but it is not working. Any suggestions of what I can do? Thank you.roy in southendMonday 23 April 2012 5:29PM
We've have just completed switchover here in Southend on Sea, Essex. Everything is fine, great pictures, strong signal, except for one oddity. I pick up ITV Anglia news, as I expect, but my neighbour in the SAME block, using the SAME communal aerial picks up ITV London news, which he doesn't want. We've spent time retuning, but can only repeat this odd situation. Can anyone explain how we pick up different transmitters for the same channel, same aerial?roy in southend: London switchover completed last Wednesday and Anglia switchover completed last July.
So either:
1. you are tuned to an Anglia transmitter (probably Sudbury) even though the aerial faces London (Crystal Palace), or;
2. you have been incredibly slow at retuning, or;
3. your block of flats have two aerials (one on Sudbury and one on Crystal Palace) which are combined and fed throughout the building's distribution system. This would give you the choice of reliable reception of either region.
Some receivers, when they encounter signals from different regional transmitters, present the user with a menu with those regions. It is often the case that there is only a single aerial which is directed at one transmitter. Therefore selection of any region other than the one of that transmitter may be liable to poor reception because the aerial was not intended to pick it up. The same thing happened in the days of analogue and would usually result in a poor picture.
As for Crystal Palace vs Sudbury, the former uses low channel numbers and the latter's are higher. During the automatic tuning scan, Crystal Palace is picked up below 30% and Sudbury is above. So unplug the aerial lead during part of the scan, to avoid the respective transmitter's signals. Dave in SouthamptonFriday 4 May 2012 2:55PM
Southampton Hi there,
If someone could help me, I'd be extremely grateful.
My postcode is SO302AG and I live in Southampton, Hampshire. I have an LG 32LD490 TV, which has in-built Freeview HD.
Following the digital switchover on March, I understood that I should have been able to receive HD channels, however I am so far unable to. Whenever I retune the TV, it fails to find the HD channels (51, 52 etc...). I have reset the TV to factory settings and tried again. I have removed the booster from my aerial. I have bought an attenuator for the signal, in case it is too strong. I have tried the TV plugged into my separate loft aerial, which does not have a particularly strong signal. In all cases, no HD channels.
Strangely, I did once manage to receive them using an set-top aerial, however the reception was very poor and other Freeview channels were not found at all.
Can anyone give me any advice? I bought the TV specifically for the Freeview HD channels, so it is frustrating not to be able to receive them.
Can anyone assist me with this?
Thanks,
DaveDave in Southampton.
Is your main aerial polarised horizontally or vertically loft or externally mounted,and is it also a group A aerial (tipped red) or a group W wideband aerial (tipped black).
One possibility could be that the aerial co-ax cable needs replacing if it is rather old as HD broadcasts do give somewhat poor performance on old co-ax aerial cable.
Once again i apologise for my incorrect location as such on my above text.
