Hi Dave, I tried your manual tuning suggestion and I can get no signal on channels 30 or 33. I can get signal on channel 23 to 29. I also noticed that the Signal Information (signal strength) is at 38 to 42. Could this be the problem? Should I get an new aerial?

Many Thanks

Ted: First establish that your TV actually has a Freeview HD/DVB-T2 tuner in it before you start worrying about aerials - because from googling your model number I cannot find anything about Freeview HD (just the model on Samsung's US website and another French website).

Find your manual and see what it says for tuner.

Hi Michael, we had good Freeview HD reception on our Samsung UE40ES6300UXXU v3 until mid december.

eg: I could enter 101 on the remote and get BBC 1 HD. I don't know about the DVB-2 tuner, I checked the manual and nothing mentioning it, what is it?

So why does my optician and those of all our family members tell us that so many are now reporting eye and neck problems when they view their TV sets? I am told, reliably, that almost all of them have the TV mounted on the wall, often too high for neck comfort and they sit too close and get eye strain.
The original ergonomics research was done in the USA, not Canada in 1948 and followed up in France, 1962, Germany, 1971 and Russia, 1998. Some I agree is now out of date as human stature has generally increased in that time so worktop heights now need to be about 45mm higher than before. That also affects eye height when sitting - but not to the extent of putting TVs 6 feet up on a wall! The modern mounting position is, in my humble opinion, a fashion that is bad for the viewer.

MikeP: I would point out that the most recent data you cite (do you have a link - Google scholar came up with very little) is 1998. It was only in that year that the first wide screen HD TV's appeared on the market, so any research would have been done on CRT's, and is of course 15 years old.

I did find a 2012 article from a Taiwanise study
Preferred viewing distance of liquid crystal high-definition television
which reckons 3-4 times the size of the screen is optimal, although the brightness and angle of viewing of any image played a role in the distance. Looking at those distances, its a little more conservative than the 2.5-3 ratio, but no where near 6x.

Your optician and family members might well report an increase in eye, neck problems, etc (but is anacdote data?) , but of course you have packaged several different possible problems together.

Wall mounting is not in itself bad, unless you are too close, have the TV too high, and with a poor angle of view. An article about mounting TV's above fireplaces in Lifehacker Why Mounting Your TV Above the Fireplace Is Never a Good Idea , met with a something of a backlash from people who had done just that, and found the criticisim unwelcome. I happen to agree with the article, but obviously not everyone has a had a negative experience.

Distance is something else, and as I've stated, 6x the screen size is simply no longer current (it could well be a plan by Specsavers to drum up custom, of course....). Even my most nervous customers are already something like 4-5 times the distance from their CRT screens, and have been so for a good decade or more, and plenty of people have been around about 10ft from the 32in LCD for at least 5 years (3.75 times screen size). 2.5x-3x the size is conservative, and my own employers thinks 1.6m from a 40in is fine.

Even if the 6x ratio was the correct advice, the reality is that nobody is using it, be it consumer groups, manufacturers or retailers, and especially consumers. It would be interesting to know what distance people actually sit from their TV's, but I know that if I suggested the 6x ratio, I would probably be laughed at.

Ted: Now that you have supplied an amended model number for your TV then that alters things insomuch that it does now indicate that your model is fitted with a DVB-T2 tuner. By the way this should be mentioned in your user manual under the "tuner / broadcasting" section.

As far as non HD reception is concerned, Samsung TV's are notorious for being susceptible to tuner overloading problems if receiving a slightly over the top signal level, with in severe cases this usually resulting in no signal warning being seen, something which "might" be affecting your HD reception by being located at under 7 miles away from the powerful Crystal Palace transmitter.

To test if this applies or not you in your particular situation you should try a "manual scan" reception test on the HD channels C30 (plus COM7 C33 from 12th) using either a set top aerial or alternatively a short piece of wire (about 5 feet or so) connected into the aerial socket of your TV.

When can we, in Marlborough Wiltshire, using the local relay transmitter, expect to receive more than 19 TV stations please. I feel we are missing out on so much because we chose not to live in a city.

Trevor Dobie: You've asked the same question each of the 4 times you've posted on this website - do you even bother to read the replies? (Hint, the answer to your question is a two letter word, and the opposite of yes.).
