Either you have it zoomed in too close or else your browser does not support the way it's done. Try a different browser. I use Firefox normally and that works fine. I sometimes use Chrome and that sometimes has the same problem as does Opera on occasion. I don't know about Safari and I never use IE if at all avoidable. I don't have W10 so don't use Edge so can't comment on that.

It is always good advice to check all the aerial connections BEFORE attempting a retune. All a retune will do is wipe all the current tuning stettings and that is not something you want to do if the problem is with one multiplex.
Checking aerial connections is something that we television service engineers have been doing for more than 70 years, as even in the days of VHF TV there were problems of corrosion affecting coaxial plugs/sockets causing loss, or poor reception, of some signals whilst others were perfect.
I did not suggest any work on the aerial other than recommending use of a log-periodic aerial for all reception of all channel now and in the future.

Without knowing where you are it is difficult to advise. A full post code entered into this website will help.
If you are having interference problems then a decent rooftop aerial is required and that needs to be very directional and carefully aimed at your best option transmitter. You also need to consider having an aerial that is suitable for all currently know signal requirements for now and into the forseeable future. Hence it is often recommended that you have a log-periodic aerial fitted. One point to watch out for is that an aerial with a narrow acceptance abngle usually has higher gain, so you need to ensure that your resultant signal strengths are between 60% and 85% on all the available multiplexes. If it is too high, you can reduce it using attenuator(s) in the coaxial feed behind the TV equipment. If it is too low, then a powered amplifier, preferably right next to the aerial (on the pole) is recommended.

If you are on a Freeview Light transmitter, then the answer is no. The commercial broadcasters consider transmitters covering smaller populations to not be economically viable for their services as they would not get sufficient return on investment.

TV manufacturers are *not* getting any subsidies from any government world wide.
If you are having difficulties viewing your TV then check that the brightness is not set too high. Likewise, ensure the contrast setting is more suited to your needs.
The UV radiation from any TV screen is minimal and the level of white light is dependent on your TV's settings as above.

According to the information near the top of this page, ITV is on the same PSB2 multiplex (channel 43, 650.00 MHz) as Channel 4, Ch5, etc. If you are able to get those then you can also get ITV. Check that it has not been moved up into the 800 range and check all your signal cables behind the TV.
BTW, there is no such thing as a 'digital' aerial, *all* UHF aerials designed for TV reception operate irrespective of the method of modulation - digital TV is modulated differently than analogue TV but the signal appears the same to the aerial. Those selling aerials as 'digital' are a con.

We need to know which transmitter (out of the over 1100 available across the country) you are using. To help us to help you please provide a full post code.

There are no reported problems with the Crystal Palace transmitter. If there were a problem, millions would be complaining, but they are not. So it is either something to do with the installation or a possible fault with the equipment design.

To those having oproblems with receiving certain programmes from Mendip, I can assure you that it is not a fault at the transmitter as I have all the usual channels still. As I'm in Trowbridge, I have a Log36 aerial with a powered amplifier adjacent to it. I did the retune yesterday after the overnoght work and all is as expected. No channe;s are missing.
So some may have the wrong aerial to cover all the channels, which is why we recommend a log-periodic aerial as that covers all the frequencies used for Freeview TV and hence will not need replacing if/when there are further changes in the future.
Bruce: It is a well known that a poor connection in an aerial feed can cause loss of just one group of channels in a multiplex. So please do as suggested and check all the leads and connections (by unplugging and then refitting) behind the TV and as far as you can safely reach to the aerial.
