Freeview is broadcast on digital multiplexes. This means that, once broken down into a stream of bits, each television channel is combined into a single transmission of 1s and 0s. This means that reception is of the multiplex first if this is lost it affects all the channels in the multiplex in the same way.
The signal strength received by the box or TV for a particular multiplex from a given transmitter determines if the data can be received or not. So, a poor signal results in no data, an adequate signal in perfect data and a low signal in either none or all.
Poor digital signal levels do not result, as they do with old-fashioned analogue television, in a sub-standardpicture or sound. Poor signals often result in a perfect data-stream, but are prone to periods of no reception. Sometimes this will be for hours, but can also be several times a minute when caused by induction from fridges, freezers, central heating systems, two-stroke scooters, baby monitors and so on.
If you have lost ALL your Freeview channels
First disconnect the aerial lead from the Freeview box or TV set and reconnect it and then follow this reset procedure to scan for channels again. If this does not result in services being restored, check the Freeview transmitters page to see if there are any engineering problems with your local transmitter.
How to check all cables, connectors and aerials
The RF connectors need to be in very good condition to work. There are two general types:
Factory-fitted connectors are very reliable as they cannot easily be taken apart, but they can be damaged by wear and tear. On the female-type the central section is often composed of two parts which can often be forced apart, resulting in a poor connection you can push them back together if this has happened with a pair of tweezers. On male connectors if the central pin is damaged, you will need a new cable. If there are any loose partials in the connector, remove them.
Another problem with these cables is that quite easy to sprain the connector at the back which causes little obvious external damage, but disconnects the internal connection. This happens often when a set-top box is pushed backwards into a cabinet.
Hand made cables can also suffer from similar problems to factory made ones and they are also prone to accidental damage from a cable being pulled. If such a connector is not firmly attached to the cable, the connector may need refitting.
Cables
Make a visual check of the cables. There are a few basic checks:
If the cable has been slashed or cut, it will not be very effective or reliable. If such a cable is fitted externally, this can allow rainwater to enter the cable and this will reduce the signal levels.
You can easily damage an RF cable by crushing it, for example in a door. If the outside of the cable has a permanent kink in the cable or has been very tightly looped, this could be the site of damage.
Aerial
For reliable and effective Freeview reception, a rooftop aerial is required. It is hard to make a visual check of such an aerial without putting yourself in potential danger.
You can make a visual check of the route between the aerial and the transmitter. Any form of obstruction will damage the digital signals. In particular trees coming into leaf, as these will leech the signal before it reaches your aerial. This applies to both trees adjacent to the aerial and at a distance.
Another common problem in cities is building work. A large crane will often change position many times during the day, and if this is between your aerial and the transmitter this can reduce the signal levels in an unpredictable way.
If your system uses a booster, the power may have failed. Check the fuse to the power to the booster.
Weather problems
There are two main weather problems that effect Freeview reception.

KMJ,Derby Wednesday 11 July 2012 10:15AM
tim: There are two points to mention with regard to the aerial technician's advice. Firstly, if you receive a very strong signal, or use an amplifier to create one, it is possible to overload the tuner so that it does not see the the required mux, rather like how much a human eye can see with a very bright light shining at it. The second point, regarding interference between signals from Knock More and those from Durris is caused by the the current frequency allocation which puts the COM muxes from Durris on the same frequencies as the PSB muxes from Knock More. Although the two transmitters are roughly at right-angles at your location it is possible that a reflection of the Durris signal is being received. It could also be that trees in the path of the Knock More signal have reduced the level of PSB1 to the point that it no longer drowns out the much lower strength, unwanted signal from Durris. Looking at the predicted reception at your location, it is suggested that you might also be able to receive the PSB muxes from Rumster Forest. This would involve the use of two aerials, diplexed to receive the COM muxes from Knock More for a full set of channels. It is interesting to note that if more spectrum is released for 4G, the frequency arrangement would change, removing the clash between PSB and COM muxes.
KMJ,Derby: Thank you very much for your explanation. It is true that sometimes the predicted reception says I can get signals from Rumster Forest and Durris. It is only recently BBC indicates that Knock More and Durris are the two transmitters for my location. Interestingly, just about the same time I lost BBC signals, a small woods half a mile away was felled. I suppose those trees were blocking the unwanted signals for many years until now? Would that be a reason? Technicians did mention about 4G spectrum in feature saying that Freeview users might need to install a filter before being able to watch tv. It looks like Freesat or Sky would be the options for me. Pity some of the channels are not available on Freesat, such as Yesterday. Anyway, thanks again for your help. It is much appreciated.
Daniele Wiseman: Yes, make another test next time you experience a blank screen giving an update on your findings, although by what you have reported the signal strength as being when you can view the channel it certainly doesn't leave very much of a safety margin before you are hovering just above the threshold for reception, this indicating that either a single booster, or preferably a booster / splitter of about 10db (min) for purposes of feeding the same level of signal to different rooms would be applicable in your situation.
By the way this especially applying where BT vision boxes are concerned, as their tuners aren't noted for being the most sensitive of devices.
Thank you also for your kind comments regarding the forum, we all try to assist wherever we can.
jb38: Yes, I heard BT Vision boxes don't have a signal booster. We have been looking at Signal Strength. We took readings then swapped the wire for the new wire which came with the other BT Vision box we had. You can see the readings below. We tried swapping in the other BT Vision box but the difference was just 1-2% and sometimes worse rather than better.So during the day I had many channels and at first I had BBC1 and BBC2 but they pixelated throughout the day making it impossible to watch those channels. Early evening we were unable to watch The Big Bang Theory as well which the girls weren't happy about, that's E4. I've noted the Signal Strengths below:
BBC1 Strength 50% (new wire 61%)(daytime 32%)
Quality 100% (daytime 18%)
BBC2 Same
ITV1 Strength 60% (new wire 78%)(daytime 50%) Quality 100%
Channel 4 Same
ITV3 Strength 61% (new wire 77%)
Quality 100%
Pick TV Strength 52% (new wire 62%)(daytime 35%) Quality 100% (daytime 18%)
Yesterday Strength 62% (new wire 75%)(daytime 70%)
Quality 100%
So it seems a signal booster is a good idea - can you recommend one - the makes seem endless?
Daniele Wiseman: Yes, I see that there is quite a difference in signal strength indications between day and night time and with a certain unbalance between the muxes in use, this of course not exactly being uncommon as signals from each of the six muxes used by Freeview very seldom ever reach a receiving aerial with the same intensity.
I am still not sure if your Toshiba's are using the outside aerial or not? but which ever one of you aerial leads is known to give the most consistent level of signal then this should be used as the master feed and likewise connected into the input a four way booster / splitter of the types shown in the link below, then each of its four outputs being fed to your various receiving devices, as this will then guarantee that each device is receiving exactly the same level of signal as well as them not affecting each other by pulling the signal down.
If by the way you only wanted your downstairs reception to be boosted then the single output booster shown on the Argos link is perfect for the job, as its by far the most powerfull of all "but" is also fitted with a variable gain just in case the signal goes over the top, this equally as bad as being weak and giving exactly the same symptoms as such.
Thanks we'll try the Argos 1 way TV aerial signal booster and sorry if I wasn't clear about the Toshiba's - there are two. There is one in the bedroom fed by the outside aerial and there is one in the dining room which does not use the outside aerial, we just have an aerial we bought in Tesco which is an indoor aerial and is fine if you don't walk around!!
Daniele Wiseman: I did realise two Toshiba's was involved in your set up but wasn't quite sure about their aerial arrangements, although when the bedroom Toshiba uses an outside aerial and the other an indoor type, then that makes it easy to compare the signal levels between both to determine which aerial is giving the best signal, of course making sure that they are both tuned to the same station.
If though the outdoor one is the best then for success it really requires it to be fed into a four way splitter, then the splitters four outputs distributed to the various rooms.
Still the single input / output device you have chosen is perfect for the purpose of boosting the downstairs signal, although it would still have been better if it was coupled into the aerial with the best signal.
Paddy Webber: Without knowing if you are referring to 15 miles North or the same South of Sandy, but you should carry out another complete re-tune just in case there was a minor glitch somewhere along the line when the rescan was taking place, as Sandy's BBC is on mux Ch27 whereas Crystal Palace is Ch23.
If though another rescan doesn't correct the problem then carry out a factory reset on whatever you are using to blank out anything stored, or if this isn't an option carry out another rescan but with the aerial removed, then once completed reconnect the aerial and go into the manual tuning menu entering Ch27 into the box provided and follow this by pressing "search" or "scan".
Once the channels are stored use the "find additional channels" to recover the five remaining muxes. (or four if you don't have HD)
Paddy Webber: There is a large overlap of the coverage areas of the Crystal Palace and Sandy Heath transmitters. When scanning for channels, the CP signal on C23 is found before SH on C27, so BBC London channels are placed in the usual positions in the channel list, then when the SH signal is scanned, upon detecting a regional variation, many tuners will put either BBC1 East, (or sometimes all the channels on PSB1 from SH) into vacant positions in the channel list, usually in the 800s. Some receivers offer an option to select a regional preference for the allocation of channels into the LCN positions, but on receivers not having this facility it will be necessary to clear the channel list, then do a manual tune of each of the Sandy Heath frequencies to store the correct set of channels.
the heat of the day causes a lot of channels to disappear but once it cools down in the evening they come back ti is definatly the heat playing havoc with tv stations in northamptonshire.
Downstairs TV is perect butupstairs will only retune in the daytime and then in the evning I lose all stations and it will not retune in the evening. I have a roof aeries with a booster on it. TV is only
3 weeks old and LED digital.Is thius area not yet completely digital?
c keenan: Simple question do you switch off the tv downstairs at the mains at night if you do you could be switching something else off like the power suply to your amplifier look for a white box that plugs into the mains your aerial will also go into this box, if so put this box onto a different plug and leave on all the time and upstairs should stay on.
C Keenan.Unless you leave a full postcode or a neaby location as such,we cannot be of much help to you.As you mentioned about your area not yet fully digital you could be anywhere either in North East England,Northern Ireland/Ulster or the Republic of Ireland/Eire !
Hi, I have 'lost' over half of my channels looking at the info above iot looks like multiplex A C and D. This has been the case for the past few days and I keep retuning to check if the channels are back but to no avail. Is there a problem other than weather that may be causing this. I'm in Dover using the Dover town transmitter. Thanks
J Sharp: Dover Town transmitter does not broadcast Mux A (aka COM4 or SDN), Mux C (aka COM5 or ArqA) and Mux D (COM6 or ArqB). Therefore, if you were picking them up before you must have been receiving them off-beam and probably opposite polarisation for your aerial.
These three multiplexes are the Commercial ("COM") ones and don't have as extensive a coverage as the Public Service ones. The small transmitters like Dover Town don't carry them because the broadcasters don't see fit to pay for them. The cost does not justify the benefit for them.
I live in central northampton NN1 1PB, I have no channels in categories A or C at all.
When I rescan I am only given the option for Cambridgeshire & Bedfordshire, is this the closest transmitter?
Beige the changeover I received all of these channels but since rescanning in June I have never received them.
Is this due to engineering works or is there something more I can do?
I have freeview built in to tv and live in fairly new bloc of flats so assume aerials and such will be a high standard.
Anyone else intermittently losing all Freeview channels from the Redruth transmitter in the last few days? Only have TV on in the evenings so not sure if it's an all-day problem.
Also, what's the significance of radiation maps from the transmitter being withheld?
Our freeviewsignal from row ridge has completely gone caput this morning we live in Bognor regis and have re tuned time and again, could it be this weeks isle of eight festival interference? How it standsat the moment thereis no signal strength and we have lost all Bbc radio channels on freeview
I live in Eastbourne and have two airials one from Heatthfield and one from Hastings My heathfield TV has had a good signal but just lately I have in evenings lost signal on areal pointing to hastings is this due to France being close to Hastings Mast or is it not any problem to any one but Me thank you
Fred Erridge: The COM channels from Hastings are co-channel (same frequencies) as the PSB relay on the top of South Cliff Tower. Therefore you may find that those channels are intermittant or non-existant.
For a list of which services are PSB (Public Service Broadcaster) and which are COM (Commercial), see this page (those with a bullet in the "E"/England column apply):
Fred Erridge: It is also the case that Hastings' PSBs share channels with the COMs of Rowridge. Before switchover these two transmitter did not share any (high-power) channels. Also, Rowridge is now broadcasting vertically and is in roughly the opposite direction to Hastings, so perhaps your aerial could be picking up a bit of interference from the back.
For these reasons, generally speaking, it is probably best to receive from Heathfield in Eastbourne where this and Hastings are possible.
Since the Olympics, our Sony svr-hdt500 has "lost" all bbc channels and has be retuned every morning. I've tried factory reset and retune; this resolves the problem until the following morning, when the problem recurs!
We live in cardiff (cf23 8nt)
Use roof arial
Welsh channels selected as region 1
It seems the Sony box is trying to find the English NBC channels instead of the welsh (if this makes sense)
Any ideas for a solution gratefully received.... Why did we go digital again??

Bryan: The "forgetting" channels usually happens because there isn't enough memory. This is caused because when the scan is performed it stores all the signals (from all transmitters) that it finds. In this case I suspect that your receiver may be opting to go with Mendip's BBC multiplex on channel 61. See whether this is the case by bringing up the signal strength screen on BBC One.
I assume that your aerial is directed to Wenvoe which is to your south west (231°) and horizontally polarised. In which case, wipe the channel memory (probably by running the automatic tuning scan with the aerial unplugged). Then manually tune in the six multiplexes: 41, 44, 47, 42, 45, 49.
C47 is the HD once and C49 will move to C39 in March next year.
Page 36 describes the procedure. It also mentions "Automatic Service Update" on the bottom right. If this in practice does a full scan when unattended then it probably wants setting to Off else you'll likely have the same result.
Why doesn't selecting Wales region not choose the right BBC channel? Good question, I don't know.
Picking up the wrong transmitter (and hence possibly wrong region) happened just as much in the days of analogue because there are many places of overlap.
Going back to what I said about running out of memory, this is only caused because signals from multiple transmitters have been picked up. Mendip is on the highest channels and is therefore scanned last. In fact C61 is the highest of the lot. The trick, therefore, is to prevent it from scanning other transmitters before one's own. This is akin to ensuring that a child doesn't fill itself full of sweets before mealtime (so that there is enough room for the proper meal).
Channel is being received well & fully able to view. Hopefully we've cracked it.... Will confirm tomorrow morning if we don't need to retune.
Thanks again
Bryan
Thanks to Dave Lyndsay; my problem is fully solved. Turning off "automatic service updates" (which is "on" by default) was a critical factor that I had previously missed. A diagnostic symptom here seems to be that I had previously had to retune *every* morning to recover missing channels, but the recovered channels were then fine until the following morning.
Thanks again
Bryan
Bryan: Perhaps the memory issue I described isn't at play and maybe it is all down to it doing a full retune every night. Either way, it's probably best to carry out the procedure of manual tuning to void the wrong channels.
Hi We have a technika tv in the dining room that comes off a splitter box (3 way ) So we can pick up Sky on analog and switch over to digital for all free veiw options . Since being told to retune digital we can no longer see much , it's like looking through milk .. But analog is perfect so it's surly not a problem with tv ... Help .....
Richard Dennis : These symptoms suggest that "if" your local Freeviewstation has recently changed its operating channel numbers then one of is now on the same channel as is being used by your Sky boxes analogue modulator link, something which can cause problems such as described dependant on the signal level being received from the Freeview transmitter.
You should try changing the RF modulators channel to say 66 - 69 and check if the Freeview problem has cleared, if so then retune your TV whilst on analogue to pick up the modulators new output channel.
If this does not work then it will be necessary to provide info on your location, this in the form of a post code or one from nearby e.g: a shop, as only then can details of the transmitter involved be checked out.
Just an afterthought, "before" carrying out the procedure mentioned try by-passing the Sky box by linking your aerial feed directly into the coax lead that goes to the splitter, as should that action clear the Freeview problem then this confirms that it is the Sky boxes modulator that is causing the problem.
I live on the West side of Weymouth and have opted to tune to the Stockland hill Tx rather than the local relay because of the additional channels available. I have run like this, quite happily, since the switch from analogue to digital; until 17th Oct 2012, that is. Since the retune I regularly lose ITV1, Ch4, Ch5, BBC1HD, BBCHD, ITVHD, CH4HD and heaven knows what else. Can someone please explain what changes were made on this date and try to explain the loss of channels.
Martyn: I dont think that its really anything to do with the EPG changes that took place then, but more the case that the retune you carried out has resulted in your box picking up incorrect channels from another transmitter.
Stockland Hill transmits on: Ch26 (BBC) - Ch23 (ITV1) - Ch29 (HD services) - Ch25 (ITV3 etc) - Ch22 (11 Pick TV) - Ch28 (15 Film 4) and so carry out a signal check on each of these channels and check if the mux channel being indicated corresponds to these mux channel numbers on the list, if not then carry out a retune with the aerial disconnected to blank out the tuners memory, then after having reconnected the aerial carry out a manual tune one at a time to recover these channels, storing anything received.
By the way, you are only predicted as being able to have having poor reception from all three of Stockland Hill's commercial channels, and so I would keep this in mind if any programmes are difficult to receive.
Martyn: Meant also to say, that when you had opted to tune to Stockland Hill rather than the local Weymouth transmitter, you aerial was changed to horizontal polarity as well as facing 297 degrees?
I receive my Freeview from Huntshaw Cross, about twenty miles away. All of a sudden channel 56 showed low signal strength and the programs would break up. I followed the procedure of removing all channels and then doing a new installation scan and now none of the channels that use 56 are listed. Everything was fine a few days ago.
Hi, I have a Toshiba TV which is less than a year old.
It has in built free-view and since I moved in to my flat in July this year it has worked perfectly. However, when I turned it last Friday 2 Nov it has lost all channels and despite countless attempts to retune it, including first time installation, it cannot find any channels whatsoever.
I am using a communal ariel that deserves 8 flats in Stevenage, Herts. I am at a total loss as to what to do to sort out.
Sal: As you are using a communal aerial system then the obvious question would be, have you checked with anyone else in the block for purposes of finding out if the problem is also affecting them?
By the way, "if" the problem is with the communal system then because you have already carried out a retune you will require to keep trying more retunes before you will know if the situation has been rectified, this being the reason why retuning should never be carried out on a Freeviewbox if the screen is blank, as all thats achieved is to wipe out everything already stored.
If the situation has not been rectified as yet, maybe you could indicate the model number of the TV in question.
I have two freeview boxes & one built into TV (two unstairs/one down)the two boxes have lost ALL freeview channels, I've tried re-set, unplugged, taken cables out & put back, switched off boosterbox (in loft) & turned back on & still have no channnels & on the box (Unstairs)it only comes up as 34% signal, down stairs no signal at all ( The other one upstairs which is built into the TV & new to the house is fine !!) all freeview boxes were fine up until 3 weeks ago !!?...any ideas as I'm getting lost reading all the other quotes (Post Code HP2). Any ideas on my delema..Thanks G
Has Winter Hill got problems or had changes made recently. In LA 11 we (us and various friends and neighbours) all appear to be suffering a loss of signal for most channels down to 30% or 40% at most on some days making even the main channels non existent or breaking up. I am fed up with constant retuning, have checked and rewired the aerial but all to no avail. Any ideas anybody
I have a 1.8 mtr dish here in Totana southern Spain, It is said we will loose all channels from the UK very soon, anybody tell me what size dish will be required to get anything at all

At 20:30hrs the film I was watching vanished only to be replaced with a "no signal" message. I checked other channels, BBC1 was very broken, BBC2 was fine, no other channels had a signal. Then my husband walked in and tried a re-tune - we lost everything as a result. I've tried turning if off for an hour, and even tried a factory reset, all to no avail. It's too dark to look at the aerial right now but I can't imagine that something has changed that suddenly. Still, I will try to look tomorrow. In the meantime, any help would be GREATLY appreciated?
Heidi: It is absolutely impossible for anyone on this site to give advice on your problem when you have not indicated your location, this in the form of a post code or one from a nearby shop etc, as only then can the reception predictor be accessed and which also gives details of the transmitter(s) that covers your area.

I have installed an aerial in the loft , run brand new cable . My postcode is GU30 7DX .
I have positioned the aerial to face the hannington transmitter near Basingstoke but cannot get any channels . On one occasion when I re-tuned I appeared to pick up 30 channels but they were mainly radio channels but they never played . Any thoughts .
Graham Cole: There is a number of stations that appears as being possible to pick up from your location Hannington @ 25 miles / 309 degrees being the only one indicating reasonably good, I feel that your best policy would be to scrub anything already stored by resetting your TV or box and then using the "manual" tune facility to tune in each of Hanningtons muxes one at a time, storing the results.
First though just to make sure that your loft aerial is correctly positioned go into your devices manual tune screen and enter Hanningtons mux Ch45 (BBC) but do NOT press search or scan, because as soon as you enter Ch45 its signal strength / quality should be indicated on the bars, just leave that screen on and use it for trimming the aerial alignment for maximum quality, albeit with the assistance of another person observing the screen.
You can then press search followed by storing the results of the search, once completed use exactly the same procedure to capture the remaining muxes.
PS: If by any chance your initial manual test on mux Ch45 results in a very low reading and which is not helped any by trimming the aerial, then give an update on this as you might require the aid of a signal booster.
Graham Cole: Just to add to that already said, when I referred to your loft aerial being correctly positioned this does not necessarily mean correctly angled from one fixed position but also to experiment with it in various parts of the loft, and with the reason for saying that being that the signal path between your location and Hannington is seen to suffer from obstructions at various points along the way starting from roughly 7 - 16 miles, 12 miles being the main one and these type of situations generally demands a certain level of experimenting to obtain the best position, this being where loft mounting generally scores over roof installations, and so when trying the initial signal test I referred to on BBC also try a few positions to the left or right just to make sure that you have the best spot, it would also be prudent to carry out the same test on say Ch41 (ITV3) as the six muxes used by main transmitters are seldom ever received at the same strengths, and of course the three commercial channels from Hannington only transmit on half the power of the PSB channels.

Brian Clark: the same problem you described has happened to my tv over the last few days. i live in m20, have tried retuning and changing leads etc. no difference. if you managed to correct the problem can you tell me how please?
I am contacting you on behalf of a person who has moved house and currently does not have her pc connected. She lived in Tytherington and received Points West as her local news station. She moved to Alveston recently and still received the same station. She had a message flash up on her tv advising her to re-tune her channels. This she did by re-tuning her digital dvd player which has Freeview and now her local news channel is BBC Wales. Would this possibly be due to her closer proximity to the Welsh transmitter or the direction her aerial is pointing?
Julian Parker: It wouldn't necessarily be due to proximity.
When the automatic tuning scan is run, a receiver scans or listens to all frequencies so as to see what it can find. At the end, it makes a 'decision' of which transmitter to go with, should more than one be found.
In this case, evidently and for whatever reason, the decision is to go with, I assume, Wenvoe.
The workaround may be to have the aerial unplugged during the part of the scan where Wenvoe's channels are, although they are only just below Mendip's.
Have the aerial unplugged up to about 55%. If, having done this some channels are missing (because the aerial was out until a bit too late) and there is a manual tune option, then add the missing ones manually:
COM4 - ITV3 etc is on UHF channel 48
PSB1 - BBC One etc is on UHF channel 49
Julian Parker: This will happen in the Bristol Channel area because the Wenvoe transmitter (BBC Wales) uses lower frequencies than the Mendip transmitter (BBC West), this results in the scan finding Wenvoe channels first, which are duly entered into the channel list, then when Mendip channels are found any which carry a variation will be placed at the end of the channel list - usually in the 800s, as the LCN (normal) positions are already occupied. If the Mendip signal is stronger than the Wenvoe signal some tuners will overwrite Wenvoe channels with identical content to store the transmitter with the strongest signal, which sometimes results in an assortment of channels from each of the available transmitters. The direction that her aerial is pointing will usually determine which transmitter offers the strongest signal, but in the first instance channels on lower frequencies are always scanned first.
