The symbol shows the location of the Oxford (Oxfordshire, England) transmitter which serves 410,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Oxford (Oxfordshire, England) mast?

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.

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.

Forgot to mention to take NO notice of the "Here's how to fix it" link on the channel list page, it's BAD advice as it takes no notice of possible faults anywhere (including your system) or Engineering (and their "auto" check isn't always correct), the transmitter is still listed for Planned Engineering as per the post just before your first.
Clearing old tuning and doing a manual tune is always the best method of ensuring you are correctly tuned.

Thank you! I tried the manual tuning and the maximum channels that managed to upload was 25. Therefore, the manual tuning didn't solve it unfortunately.
I've reset the tv and completed auto tune and now is back to 101 channels, but as per initial post, main channels sync has the BBCs, ITVs, Ch4/5 don't work at all, only the digital channels.
Will call the flat management to see what the resolution is. As I don't think it's the TV.
Any other suggestions are welcomed. But may have to wait for this work to be done maybe.

They are all "digital" channels! I assume you mean it's the HD channels that don't work.
If you only managed to load 25 channels with manual tune, it sounds a bit like you may have only tuned one multiplex. There's no good reason that an automatic tune would have found more TV channels than a manual tune of all the UHF channels. Actually it's normally the reverse. In cases where (for whatever reason, fault etc) where there may be weaker signals, the automatic tune cna miss then and a manual tune will find them.
Can you tell me which 25 channels it loaded, when you tried manual tune?
It's sounding like there could be some very intermittent connection here. Works (badly maybe) one minute, then not the next.
Did you try swapping/changing that flylead/patch lead from the wall plate to the TV?
Is there more than one socket on the wall-plate? If so are they labelled?
Without clearing your now current tuning, try adding a manual tune to UHF channel 47. This is the HD multiplex carrying the HD channels.
Select Home/Menu button. Scroll to Settings. Select Installation or Tuning. (what it shows is model dependant). Then Select "Manual Channel scan". Follow the menu and enter UHF channel 47 when prompted for the channel number.
Can you give the Strength and Quality/error figures for the TV channels I suggested before -
eg. 1, 3, 101, 16, 11, 12, and 7
Without some of this information we are clutching at straws here.
