Paul Davies: Your DVD is just a player, and netflix etc are via the web, so they have no connection with your TV signal.

'Resetting Freeview' is just retuning the TV, or returninng the TV to its 'factory/initial setup' state which can be done via the menu. However, you need to discover why your TV signal is breaking up, since Mendip should give you a perfectly fine signal.

Check which transmitter the TV is tuned into, and then note signal strength - it could have locked onto a transmitter much further away. You should be able to manually tune from the setup menu, and you should look for Channel 45, etc on that to use Mendip.

If the signal is weak and your looking at the correct transmitter, check your cabling, because that a primae reason for a problem.

Use Mendip - Digital UK reckons you should get a good signal, and you'll get the full range of channels. Wenvoe seems even better, but there seems to be something on the signal path pretty close to you. Look at which way your aerial and everyone else's is pointing - which one is it?

Joy Reynolds: we need a postcode, to find out where you are in relation to the transmitter. next, check signal levels and which transmitter your actually tuned into, and then check the cables - are they loose, etc.

peter: But the BBC does not own or operate the transmitters - they were sold off years ago - Aquiva operates them, and the BBC, ITV pays them to transmit their channels. So its Aquiva you should be asking - I'm sure the BBC would like it up and running as soon as possible.

Mardler : North Norfolk has always been problematic for TV reception from Talcneston - the geography of the area means a lot of places are blocked, hence the reason why many aerials use Belmont instead.

Thats the nature of the physics - when people start saying that their reception has got a lot worse, then that points to problems within the home system - the transmitter is in the same place, with the same power output, etc. There are always people who insist it has to be the transmitter, the BBC, etc, but it very seldom is. And some will tie themselves in knots trying to explain signal loss away, often ending up confusing themselves.

If people find it easier to go to Freesat, etc, fine. There is no point in repeatedly trying to do what cannot be done - physics hasn't changed. But if the change is relatively sudden, then almost certainly its not the transmitter or even Freeview itself.

MikeP: My box has suddenly lost BBC4 HD - it could be that a mux change means a retune.

Alan Hume: I just retuned my HD box, and BBC4 HD reappeared, so it could just be that the mux move confused things.

RayB: If you've changed the TV, and your still not getting HD channels, then logically its:

a) The problem lies with your system

b) Your not tuned to a transmitter that carries HD channels (which is impossible)

c) The HD channels are being lost, perhaps because of signal strength, or the mux is being blocked in some way, or the aerial itself.

I'm not sure what the problem is, but there are some clues. The 100% signal strength makes sense if your tuned into Welwyn (and excludes a loose connection, etc), but obviously thats a very limited service.

I'd ask your neighbours what services they get - the plot seems to think that Hemel Hempstead has a big problem with signal path, but Digital UK reckon that Crystal Palace/Sandy Heath are doable. You might need to move the aerial, but if yours is pointing a different way, and they get a full service, then it might be worth a try.

HD channels can blank out if there is too high a signal, but whats strange is that you dont even seem to be picking any up.

I'd start with looking at the the aerials in the area. I just looked on Google maps, and most of the aerials seem to be pointing vaguely east - which would mean Chrystal Palace. Try a manual tune and see if you can pick it up, although why the TV isn't picking it up first anyway is a mystery. It might even be worth tuning it via someone elses aerial, and then see if that works with your own system!

Thats the best I can suggest, but I'm sure people more expert than me can advise better.

J Morris: Check the signal strength of the TV with the problem. Signal strength could be too high or low - TV tuners can have different sensitivity, and of course the wiring to a particular TV ight be at fault.

Samantha Cutforth: Put your postcode into the site, and follow the links - Digital UK's site will tell you the compass bearing.

However, indoor aerials are pretty rubbish unless you are fairly close to the transmitter, so you just have to try it.

Brian Wright: I'm surprised your OLED isn't giving you a good picture in HD - upscaling and processing on a decent 4K is normally pretty good, and and OLED is generally very good.

Certainly all the OLED's we have where I work are generally on HD feeds (because its what I expect customers to actually watch most of the time), and they are all very good indeed (although the Panasonic is my favourite, and OLED is indeed the nearest to plasma for skin tone and black levels).

Dont forget that the difference between broadcast HD and blu ray is between 1080i and 1080p - I've seen 4k sets using both LED and OLED on both, and the difference isn't huge between either source.

LG did make their first OLEDs in HD and 4K, but since they were relatively expensive and the market was moving towards 4K anyway, although they were cheaper, the HD panels were not as popular - people tended to want the lot at that price. However, we did have one customer who bought the OLED in HD, saying that he didn't need the 4K, but did want the picture quality. thats fairly pragmatic, but the market has moved to pretty much everything being 4K, and content is building.
