The symbol shows the location of the Mendip (Somerset, England) transmitter which serves 720,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Mendip (Somerset, England) mast?

I live in the SN10 3BJ post Code area. I live in a Retirement Complex containing some 44 Flats/Bungalows.Ae on a very high roof Over half of these units cannot recieve BBC 1 without from time to time massive interference, on sound and picture. Before the change over we were happy old codgers with TV to look at.Now we are not.We have re-tuned our TV and recorder at least six times. Reading some of the Comments above, I really think we have been miss sold HD Ready equipment.

Maybe the user manual for the particular TV would help? See Freeview Retune - list of manuals | Digital switchover | ukfree.tv - 10 years of independent, free digital TV advice for some listed on this site.
Giving the model number helps as they vary quite a lot.
Is she on a communal aerial system? Some seem to have problems with the changed channel settings.

Mr R.A. Shergold: I think that you need to speak to the party responsible for the aerial system. The issue clearly lies with it and so there is nothing you can do.
Sometimes communal aerial systems need adjustment where new frequencies come into use, as is the case here.
If a set is tuned correctly then there is nothing to be gained by retuned - it is a waste of time and effort. For BBC standard definition (non-HD) services the signal strength screen should say that it is tuned to UHF channel 49 (698MHz). If that is what it is on then retuning will achieve nothing.

Michael Perry:- (funny that I am Michael Penny!) Thank you for your suggestion. Yes we have done everything in the manual, but I think there must be a signal strength problem as it now fails to find any channels. We share an aerial mast and a satellite dish, but I think we each have separate terrestrial antennae. There are certainly two UHF ariels on the same pole as the dish as well as a VHF radio ariel.

Just a thought but might seem strange at first: try doing a full scan without the aerial plugged in (that might well clear any stored channel information first). You won't get any channels found, I hope. Then plug the aerial back in and do another full scan. What do you get then?
What model is her TV?
I'm sure the transmitter is working correctly, else how do so many have no problems, but I suspect that some equipment was not designed to easily cope with all the changes they are making just to make room for 4G mobile phone data!

We did that. NBG. We live in quite an exposed location and I think the prevailing winds may have degraded the aerial connections more as each day passes.
When I first looked to see what could be done we were getting sufficient signal for all channels (even the BBC ones appeared occasionally), but somehow the set was not clearing the channels completely and would not hold the new ones in its memory. My neighbour spoke to a help line and was told to do what you suggested - tune it with no antenna attached.
The last time I looked I noticed the signal strength was briefly displayed as 4.9% I had not seen that displayed before.
We are now quite resigned to the fact that we will need to get a new aerial - or at least get the existing connections checked by an engineer. The TV model is a Ferguson F1603LVD2 16" HD Ready Digital LCD TV + DVD. We have the manual.

Mike: Purely on the issue of the TV not holding channels, according to info seen that model should have a "first time installation" option in the set up menu (manual page 19) that has the effect of returning the TV back to its default settings, was this tried?

Jb38. Yes first time installation was tried many times, with & without cable plugged in. As I said I think our difficulties were exacerbated by by a co-incidental problem with a degradation of signal due to the increasing failure of the cable and set up at our end. We will sometime get an engineer in to check that side of things.

For those who think their aerial may be suspect, you can test the signal strength using a simple meter, such as a Philex SLx - 27867R Digital TV Signal Strength Meter. Look on Amazon if you like (http://www.amazon.co.uk/Philex-SLx-27867R-Digital-Strength/dp/B001GXQUNQ). It seems none of the meters available now can differentiate between the different signals broadcast for DTV so won't tell you if some are weaker than others.
Might be worth a try for some.

Glad to see It's not just me.
Since the retune, I too have lost all BBC progs. I only get a usable signal from 52, 54 and 56. 48 and 49 both give a very faint unusable signal. Humax box and Sharp Aquos TV both give the same result. Nobody seems to be listening, 'no reported problems' despite the fact that I and doubless many others have reported the problem.
