Neil:
The Freeview Detailed Coverage Checker shows that you should get all multiplexes with no issue, excellent reception 100% (except the Local mux which may be a very small fraction less reliable. So even with the Tropospheric Ducting I'm not certain that it's necessarily the most likely cause BUT if you are seeing the strength/quality vary during the daylight hours (an hour after sunrise to an hour before sunset) current predictions means it's still possible.
However with your reported 75/50 strength/quality there is a good chance you may have too much signal for the new set! What sort of aerial do you have? Do you have any splitters/boosters etc.?
Too much signal can overload the tuner and the result is pixellation/breakup of pictures/sound and "apparent signal levels can read less than they are, but the other indicator is the quality figure drops.
If you do have a booster/splitter and it has variable gain, turn it down. If it's just a booster take it out of circuit and plug the aerial direct to the TV. In the latter case, if the signal/quality still varies, it would be a good idea to check all your coax plugs, connections etc for corrosion, water ingress, bad connections etc.
If you don't have a booster etc, do you have any old splitters or attenuators you can put in circuit just to provide some insertion loss to see if that improves the situation.
Depending on your reply, I can give some further suggestions.

Hi, yes this is a problem that's not unheard of, especially with older sets and also set memory can get "confused". If you've not experienced the issue before, it could be due to "Tropospheric Ducting" with the current weather conditions, which causes signals from other transmitters to travel much further and you are picking up the COM4/SDN multiplex on C29 from another transmitter.
The easiest way to deal with this is to unplug the aerial and do an automatic full retune which should clear memory of all previous tuning as no channels will be found. Plug the aerial back in and then carry out a manual retune for each of the Heathfield UHF channels.
If you can't do a manual retune, look at the scanning indicator and estimate where it is once it has passed C29 but before it gets to C40. Clear the old tuning again, the repeat the automatic retune but do not plug the aerial back in until after the indicator has passed C29 but before it gets to C40.
What will not be helping matters right now is that the Heathfield transmitter has Planned engineering with "Possible Weak signal" so you might have to repeat this a few times to get it right if signals are not at normal levels when you do it.

As John martin says, a lot of pensioners struggle and do not qualify for pension credit or find the forms too complicated. The fairer way is to do it by tax code, the government knows all tax codes! Anyone on a high rate code does not get a free licence, simples.
The real fairest way would be to scrap the licence fee and the money come from general taxation. If you have the income you are paying tax, the more income the more tax. Even simpler.

Firstly don't retune under no signal conditions, it just clears all correct tuning.
Unfortunately the transmitter is currently listed for Planned Engineering with "Possible service Interruptions" so you will experience loss of signals maybe a few times.
The signals will return at various stages during the maintenance. IF you retuned when you had no signal, you will have to retune again once the signals have returned. You may have to do this several times if you don't get all channels back the first time, as all the multiplexes may not be back on at the same moment.

My post Wednesday, 22 April 2020 on p219 lists all the current UHF channels for Emley, except of course COM8 is closing. COM7 is still there with Now 80s on C55. If you are not picking it up, try a manual tune on C55, there's some variable "tropo" around which my cause periodic interference!

I doubt it, see their website Talking Pictures TV - An Archive Film & TV Channel
You could always contact them and ask if there's some devious way!

You need to sort out your COM7 reception. You have not provided any feedback to the comments and suggestions to the variety of posts you've made recently.

Sandy Heath is listed for Planned Engineering with "Possible weak signal", which in some locations will seem like no signal. The Local Multiplex on C35 comes from the nearby Madingley transmitter which probably will remain unaffected.

Anthony:
Yes all the changes have now taken place. they never say when they are going to do it, it's generally in the morning with these sorts of changes unlike transmitter frequency changes which usually happen overnight.
To ensure everything ends up in the correct place, the best way to do this retune is to unplug the aerial and do a full automatic retune which should clear all the previous tuning. Plug the aerial back in an do a manual tune for all the Mendip UHF channels EXCEPT C56. HTH.
