To deal with the problem you must clear the channel list completely and then rescan - if your box has it in the menus, please the 'installation menu' to do an initial scan or a reset to factory settings or First Time Installation. You MUST delete the entire existing list of channels. On most boxes this technique can be also be used:

Try this:

1) unplug your Freeview box (or idTV) from the mains;



2) unplug the aerial from the Freeview box by disconnecting the cable from the 'RF in' socket;



3) wait 30 seconds;

4) plug Freeview box (or idTV) mains back in;



5) do a complete scan for channels - it will fail without the aerial. (This may be in the installation or initialization menu, and is distinct from any 'add channels option'). Once this is done your channel line up should be empty;



6) reinsert aerial by reconnecting to the 'RF in' connection;



7) do a complete scan for channels again.



The Freeview channel line-up provided by six "multiplexes" - each of which carry five or more TV channels, radio channels, text services and EPG data. In this diagram each ROW represents a multiplex. If you are still missing a whole multiplex (ie everything on the row) you may need to replace your aerial with a wideband type, purchase a larger aerial or you may have interference from a VCR, games console, Sky Digibox or similar.

What is the channel no - not easily accessible on your site. Why can I not get BBC 4 HD on either 22 or 55

H N Morris:

Judging by the phrasing of your post, I thinks it's first best to explain that there are 2 HD multiplexes that broadcast HD channels. Whether they are HD or SD, see Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplex.
Note - the (temporary) COM7 multiplex which carries BBC4 HD is only broadcast from 25 main transmitters and only some main transmitters serving large centres of population have a Local multiplex. Both those multiplexes may not be received by everyone who get the other multiplexes, it depends on location, because of the power used and type of transmission.

The two main transmitters that you could receive that give good reception both have COM7 which you are predicted to receive (assuming you have the correct aerial) but you aren't predicted to receive the Local multiplexes from either (they are beamed towards the major city areas they serve).

So it depends which way your aerial is pointing whether you get the Waltham transmitter (Central news) at bearing 175 degrees (5 degrees E of due S) or the Belmont transmitter (Yorkshire news) at bearing 54 degrees (9 degrees E of NE). Your reference to "22" suggests Belmont which is the BBCA/PSB21 multiplex. As mentioned BBC4 HD is on COM7, UHF C55.

You need a Group T or Wideband aerial to get all multiplexes from Belmont (or Waltham come to that). Belmont was originally an old aerial Group A transmitter and the other main channels are in Group A, but if you still have an old Group A aerial you are unlikely to get any signal from COM7. You could try a manual tune on UHF C55 as auto tuning can sometimes miss weak signals.

Sorry for the typo in the previous post, UHF C22 at Belmont is the PSB1/BBCA multiplex (not PSB21 as it ended up!).

I've been having a signal problem with channel 20 drama,it started about 6 weeks ago,never had issues with it before,picture started breaking up,waste of time trying to watch anything,last 2 days i'm just getting ,no signal.Now getting no signal on paramount ch.31 & sony ch.40.

I've unplugged & disconected the aerial from the youview box,retuned without the aerial connected,retuned again with the aerial connected,didn't fix the problems.

I have the same problems with Channel 20 & Paramount CH 31 using my TV tuner.The tv has it's own aerial lead as does the youview box.

The aerial has a mast head amplifier,so the lead from the aerial is connected to the coax plate in the wall,a cable is then connected to a power supply unit & one coax is then taken to the tv & one to the you view box.

I'm on the Winter Hill transmitter. L31 area.

Drama, Paramount and Sony Movies Action are all on the COM4/SDN multiplex. See Channel listings for Industry Professionals | Freeview for which channels are on which multiplex.

Now, although there was some transmitter work at Winter Hill recently which was initially unlisted (and supposedly finished a week or so ago) it might be that this multiplex got tuned to another transmitter (possibly Storeton or Moel-y-Parc)) when Winter Hill was off-air or weak signal, it wouldn't be as good a signal and this could account for the picture break-up.

BUT..... you mention "paramount ch.31 & sony ch.40". Now those programmes are no longer on those LCNs (as you may have noted from the list I linked above) they all moved up one channel due to changes on the 4th November Updates and alerts | Freeview
This means that you need a full retune. Now the trick of doing one with the aerial removed first doesn't work on the Youview box IIRC, but should on your TV. For the Youview box if a normal retune doesn't work you may have to do a reset (refer to the manual) this might mean you have to reprogram any recordings you've set up.

So try the full retunes and see if that restores everything correctly and solves the problem.
You may want to check in the tuning sections that you are tuned correctly to the Winter Hill UHF channels -
The main multiplexes are C32, C34, C35, C29, C31, C37, C55 for PSBs1-3, COMs 4-7.
The Local ones are Local Manchester, Manchester GI on C24 & C27.
Liverpool Local mux on C21, Preston Local mux on C40.
Which Local multiplexes you may get will depend on your precise location.
If you are still having problems post back with a full postcode so that we can look at our predicted reception and see if there's any faults listed affecting your locale.

Thanks for your reply.

I'll give what you have suggested a try but confess that the refs. to mux & frequencies go over my head.I clicked on C32 & a map popped up showing an icon with hd on it,i hovered over it & it was the MOEL transmitter in i think Flintshire,Winter Hill wasn't there.

There are times when i have done a routine retune & i get BBC1,BBC2 &ITV in the Welsh versions.Not sure what that indicates except that maybe the signal for the BEEB stations is stronger from Moel than from Winter Hill.

Ah, I can see where there maybe a bit of confusion. As has been mentioned a few times around this site, many pages haven't been updated with the correct information since the 700MHz Clearance program and the channel usage pages are another example I'm afraid - the site owner just doesn't seem to have had time!
C32 is no longer used by Moel-y-Parc, it was previously used for COM7 before that was moved to the SFN channel of C55.

As you've obviously noted, you've got tuned on occasion to Welsh channels which might come from Moel-y-Parc or Storeton which also relays the Welsh variants. It might be an idea to look up at you aerial and make sure it appears undamaged and is pointing in the correct direction. Missing or damaged elements will affect its directional capabilities and ability to reject unwanted signals from the wrong direction, although most aerials have what are called "side-lobes" and will pick up some strong signals at other angles.

I've gone through all the update details again,Channel 20 is back but picture is breaking up on the tv tuner & the youview tuner.Paramount also breaking up.

I didn't mention earlier that i had also lost around 30 channels on the youview box,thats happened before,when it does happen i lose channel 20 completely.Then for some reason the lost channels tune in again,strange!!.

The aerial looks ok from what i can see,it's 20 years old now ,maybe i should change it,i think i've probably done as much as i can,Looks like i'll have to get the aerial guy to check it out.

Thanks for your help.

Now you've told us that your aerial is 20 years old, that's the problem. Since the end of the 700MHz Clearance program (last changes at Winter Hill were on August 12th) you need a Group T/Wideband aerial to get all mutliplexes.

Freeview's advice if you are still missing channels after a full retune is -
Contact the Freeview Advice Line free on 0808 100 0288. You may be eligible for free in-home support, including aerial work if needed.
Providing it's your own home, not rented from a landlord (ie. the aerial is the landlord's responsibility) then Freeview should put you in touch with DMSL (Digital Mobile Spectrum Limited) to arrange an appointment for a free aerial upgrade. Make sure you say that since the changes you have been losing signal from a variety of channels including BBC ones and your aerial is 20 years old and you've been told the aerial needs an upgrade.
