I think what we have to do regardless of where we live and what transmitter we get our signal from is retune the box every hour? There we go problem solved.
In my case, I don't think it will be excessive signal strength per se. I'm running at about 73-75% on channels 101-105. That is why I'm tempted to re-point my aerial to Bilsdale and retune - which is roughly the same distance from me as Emley Moor but with a much clearer line of sight across the vale of York - and see what signal level I get and whether the problem disappears.
I bought an attenuator and reduced my signal to 80%, as recommended by BT, with no improvement.
If anyone having this issue can visit this thread, and PM Sarah with your details.. I think it will help.. this is the first sign of someone actually taking this seriously..
Pardon me for butting in, but I have a similar problem. But, it is not with the HD channels. It is with the 'ordinary' FreeView channels BBC1&2 through the YouView box.
Like many, many people, I have retuned many times, changed cables, had an aerial check. ETC. ETC. Nothing Worked.
I was fed up of constant picture breakup on these channels, and begrudge paying through the nose for a service that isn't what it professes to be. So, Yesterday I contacted the 'online chat' helpline. I 'spoke' to a very nice chap called Animesh.
Having gone through numerous checks (all of which had been done many times before), he told me that he would check my YouView box remotely. This took quite a time, but he eventually came back and told me that there was a lot of 'interference' on my box, and that he would clear it.
After a further wait of ten minutes or so, the signal strength on my box went to 90 - 100%. The signal Quality went to 100%. Previously, although the strength had been OK. the quality had been anywhere between 0 - 100%.
It has only been twenty four hours since this happened, but the signal has hardly altered, and the picture is perfect. I can only hope that it lasts. I will post again if it goes back to what it was before.
Once again, apologies for butting in, but I thought that this may be of some help.
Thanks, whilst that interesting in its own right... The issue here is not channel breakup, our channels get deleted from the listing, and we have to retune.
I see that BT still won't do anything or accept responsibilty and the problem is marked as resolved. In what way is it resolved?
On Sunday 13102019 I had 166 channels. I re-tuned the box once again and this increased to 173 channels. I checked the signal strength and quality on all the HD channels and they were showing 93% strength and 100% quality. This morning there were 164, so by re-tuning I now have less channels than before. Great.
When are BT going to actually do something about this situation?
I have been back to BT about my problem. I have registered a complaint that I am paying for something that I cannot use fully.
They are sending me a new YouView box. (ha ha), and say that they will reimburse me for the lack of service.
I await developments?
Not sure BT are doing much. Someone called Sarah on the YouView forum (not sure of her role, but she seems to announce details of software updates, and be in touch with BT) seems to be aware, and is asking for examples with specific information of box model, serial number, example channels that go.
