phil : Manual tuning will only restore the missing mux if you have a strong enough signal, although it is certainly worth trying. Many viewers will require a new aerial, which should be available free of charge to those who don't have satellite or cable.

Since com7 has gone to ch 36 I am having problems with it pixellating and sound cutting out when checking the signal on my you view box it was a lot weaker than ch 33 and ch 35 is the transmitter output on ch 36 at much lower power than the other two thirties channels.I can see the mendip mast on a clear day from my downstairs lounge window and have a professionally installed log periodic roof aerial. my postcode is np11 6qx.

phil: You are not correct in what you state. StevensOnln1 has explained it correctly. Sometimes for obscure reasons tuners can miss a channel on an auto scan. If you've experienced those sort of issues (and you have an adequate signal - which might mean a new aerial to achieve that!) then it often pays to do a factory reset/a complete scan with the aerial unplugged to clear all the stored information from the set and then start again.

Barrie Wreford: The transmitter power for COMs 7&8 has not changed since the UHF channel move. It is slightly lower than the other main muxes, but this should not affect your reception - especially if you can see the transmitter! This is also confirmed by the DigitalUK Coverage Checker Coverage Checker - Detailed View for your location. As others have mentioned previously, sometimes poorer reception on one mux can be due to a possible bad connection somewhere in your system. It would be worth checking through that all the connections, coax & aerial plugs/sockets etc are clean and free from corrosion or damage. I presume you have checked that the aerial hasn't moved in any recent high winds and is pointing correctly. If it's been installed for some considerable time, it could be worth checking the connections at the aerial itself if all else has failed to resolve the problem.

Chris.SE is correct in what he says about checking connections. I lost channel 36 (Com 7) on my lounge television, channels 33 and 35 (Arq. A and Com 8) worked okay, although the signal level wasn't fantastic. All other used channels.had 'reasonable' signal levels.

Problem was caused by a poor connection at the aerial wall box, after a bit of wiggling channel 36 returned and the signal level on other channels also increased. So the moral of the story is check connections, even if other channels are working fine.

Terry: ITV West is on UHF channel 54 from Mendip. ITV West is only available in SD on Freeview (the HD version is currently only available on satellite) so you will get a different region if you watch ITV HD on Freeview.

Terry: David Newton is very unlikely to respond to your query as his post is very very old, and his problem appears to be due to having an old band C/D aerial.
In your case it's as StevensOnln1 explains, you will get ITV Central instead. This is because of the way ITV distributes the HD channels to transmitters - it's separate from the SD channel distribution.

If you've lost ITV3 in the last month it has moved. Its now on PSB2 (C54/738.0MHz) same as ITV, ITV2 and ITV4.

I was very pleased to see that the software on my TV (Bush Freeview Play HD 32" Argos special, bought just before Xmas) now has two options if you go for a full retune - the usual "replace all channels" and a new "update all channels" which keeps the channels in the order I want, rather than the muddled order they used to come in.

Just to update.

Got an aerial guy from Aerial Express to come round and replace my aerial. Don't know the make or model, but the problem has gone, and I'm getting a signal strength of 10 where as before it was just one.

So sorted.

Thanks for the feedback guys.
