When watching BBC one HD and SD the picture breaks up frequently. The picture is distorted and the sound goes as well. Coupled with this, Catch up and on Demand is never available. I have called before about this but it was never rectified.
I ran the website based test for TV and have checked all the cables are tight.
Thank you for time the time to write into the Community I am sorry to read that there's been some picture breakup on the TV services.
I have been able to test the connection and I have seen some issues that would need address, along with some serious downstream power level problems on the broadband in the home.
I would suggest an engineer at this point to help adjust some of the signals in the home to bring the services back on properly. If you can have a little look inside your 'Inbox', you'll see I've sent you a 'Private Message'. You can find this at the top right of the page, purple envelope
