Dave Lindsay: Help. We don't have any BBC channels since yesterday and have retuned umpteen times. Tempers are fraying in this house. What can we do to get BBC channels back. In fact, I've retuned again and have lost even more now. WTF!

We have no BBC channels in Taunton, have reset the tv back to factory settings and still not picking up any BBC channels. Have just asked friends in Taunton and Street and they have no BBC channels either. We had a new aerial so sure this is not the problem, please sort it out!!

Dave, I live south of Taunton and after several manual retunes still have no BBC channels either - although my neighbour has (she has an old set top box)! If it is a general problem, is there someone somewhere who might be able to do something about it? Can we contact them? Thanks.

John Crabb: It shouldn't be expected to be an issue.

Failing all else, then the only option left is to do a full reset on the TV in the hope that there is some remnant of the old BBC channel left in its memory now that the full reset will clear. This will, of course, likely reset everything else like picture settings.

The only other thing is if you have another aerial facing another transmitter and it is combined with the Mendip one; this may be an issue with C49 and C48 from Mendip.

Dave,

I am just a bit suspicious of a more general problem when I read the posts that say they have no C49 in Taunton, Wellington and Street.

John Crabb: I see what you're saying; there are quite a few reports on the south-west side of the transmitter.

Alison: All the very best to you as well.

Maybe you can use a piece of wire (if you don't have a set-top aerial. A wire maybe 30cm long into the inner part of the aerial socket.

You may be able to use the aerial lead in the back of the set and put your bit of wire in the end of that. That way you might be able to affix the wire to the window where you get better reception. A wire coat-hanger may do, although I think that some are coated in something which might act as an insulator. You may be able to put a file to it to remove the coating on the end that is inserted into the aerial socket. There is no need to file away the coating elsewhere.

See:

Digital UK - Coverage checker

Enter your postcode and tick "Detailed view". This will give suggestions for transmitters. "BBC A" is the BBC standard definition TV and radio, which you are missing. If you can't pick up C49 from Mendip then maybe there is another transmitter that you can pick up in the mean time.

Near the top, under "Digital transmitters", it gives the bearing of each transmitter. The one(s) to try first are those for which the side of the building you are on face.
