Sorry, also meant to ask, you mentioned your "next door" app, were those with problems your immediate neighbours?
Or were those reports from people further afield? Considering the locale and terrain between the area and the transmitter those further afield may have much poorer predicted reception from Oxford.

Chris.SE: having now checked the signal strength and quality I find I get a full 10 on the signal strength and 0 quality , except channel 7 and the other LOX channels where I get 60 to 75 percent, the same I get for LOX normally, but quality is still zero. I tried putting up to 18db attenuation at the set end, and that made no difference apart from the strength was reduced.
This would suggest it is the amplifier not the tv fronted, though the LOX result confuses me as I would have expected if the amplifier was overloaded it would not matter what the received signal strength was from the transmitter.
The people who responded on 'next door' live not to far away, but no immediate neighbours as many of those we know to speak to are on Virgin.
I hopefully have an aerial man coming out tomorrow who no doubt will charge an arm and a leg, but if it is not 700mhz interferance the amplifier must be oscillating or doing something silly.

Well good luck with that then, yes the amp could be doing silly things like oscillating.
I hope he's got a spectrum analyser.

Chris.SE: sorry meant to come back. Despite my quick check on the power supply for the amplifier which said it was OK, when the aerial company who attended, first one kept rescheduling, looked with a spectrum analyser it was doing something odd. New psu and everything OK.

Thanks for updating us on the outcome. A process of elimination had at least pointed the finger in a suitable direction and final diagnosis would have been tricky without specialist equipment other than by equipment substitution. Remote diagnosis is often difficult.
I hope the aerial man didn't charge a huge arm and leg!

Hello,
My Toshiba 2017 HD tv which had all channels including HDtv 101,102,103 etc... started to pixelate late October 2023. Then channels 1-5 bbc, itv,c4-5 all were pixelating and unbearable to watch.
We rest/ retuned Automatic and we lost the HD channels, but all others remain. The pixelated on the main 5 channels is still there.
As it's a block of flats, we asked other neighbours and no one has reported issues. We are not sure how to continue to resolve this without expensive costs.
Does anyone have any solutions? Or how do I find the manual tuning frequencies?

Hi. Automatic retuning when you have pixellated pictures/sound breakup or no signal, is never a good idea if you were correctly tuned to start with. You cannot tune to signals that are not there or can't be decoded. The usual results to clear the correct tuning and sometimes mistune you to weak signals from another transmitter which may disappear.
The UHF channels (and frequencies) are in the very top section of this page. The best way to manual retune is to first clear the current tuning by unplugging the aerial and doing a full automatic retune, no channels should be found.
Plug the aerial back in, and then manually tune each of the UHF channels.
The Oxford transmitter is currently listed for Planned Engineering but you shouldn't have any problems being so close to the transmitter unless there is a brief period of service interruption.
For the sake of clarity - Oxford's UHF channels which are C41, C44, C47, C29, C31, & C37.
That's in multiplex order PSB1/BBCA, PSB2/D3&4, PSB3/BBCB HD, COM4/SDN, COM5/ARQA, COM6/ARQB.
C means channel, if you hover over those numbers it tells you the frequency if you need those.
The Local multiplex is on C22 in your area.
Tell us how you get on. If you still have problems with pixellation, look through the tuning section for Signal Strength and Quality (or Error) figures and post those for each UHF channel.

Chris.SE:
Thank you for your response. I forgot to add previously:
1. I tried the reset option on TV, to factory reset. Didn't work.
2. I tried to Automatic return without areal and then with areal, but once again only 101 channels were dowloaded, excluding the previous HD. Also, the BBCs, ITVs and Ch4/5 still don't work.
3. Yesterday, i purchased a 5A F-Plug Amplifier Power Supply 1.25m from Screwfix to see if it's more of a booster issue. The good news is that product did stop the Pixelation with ITV and CH4/5. However, BBC dissapeared. When i retuned with the booster on, it went from 101 channels to approx 88.
Just to also add, the TV is connected to wifi, and everytime I scroll through BBC channels it says 100% Strenght. When I added the booster the strenth actually dropped to less than 50%.
Therefore, even with the booster, there's still some issues.
I will try to play around with the manaul re-tuning later today.
I am just confused to what it could be, as accordiing to the block of flats managment, noone else has complained about it. Therefore, this must be just my TV issue.
thanks for your response.

The big mistake is you have wasted your money on a booster. The signal strength dropping when it's in use is typical of the result of tuner front end overload. Take it out of circuit. As a side query, why did you get an F-plug device, surely your connections are coax?
First thing I would try is swap any patch leads. The one you normally use to connect from the wall socket direct to the TV, they can go faulty, swap that for another one. I'm assuming your wall socket normally connect direct to the TV, ie. you don't have any other devices in-line such as a PVR etc.
You need to check with your neighbours again as to whether they are actually watching the HD channels. Many don't bother because they have to make 3 key presses instead of one eg. 101 instead of 1, 102 instead of 2, etc.
Also they may have some occasional pixellation with ITV channels but ignoring it and perhaps not mentioned it.
There could still be a problem with the distribution that's affecting your outlet and not all/many of the others, that's why checking more exactly with the neighbours is important.
The building management may be wrong in their assumption, but we need to be sure you've eliminated any possible issues with your setup.
The interesting point I note here, is that your issues are with the multiplexes on the highest frequency UHF channels. This can be typical of cable or connection issues and it's important to eliminate any with your own setup.
The fact you are connected to wifi should make no difference.
Scrolling through the BBC channels and mentioning those figures isn't an awful lot of help, we need the figures from channels from each multiplex.
Here is what is usually an up-to-date list of which TV channels are carried on which multiplex -
Channel listings for Industry Professionals | Freeview
So you can select a TV channel from each, so eg. 1, 3, 101, 16, 11, 12, 7
Note the figures for each - we don't just want strength as that's not an ideal indicator though 100% maybe of concern for overload, but it's the Quality % (or error rate) which is more important.
