Have you recently noticed new interference to your free to view services – TV received through an aerial – such as Freeview, BT, Talk Talk Vision and YouView? Has the sound become poor, do you have blocky images (pixelation) or a ‘no signal’ message being shown on screen? You may have received a postcard from us advising this might happen.
The interference may be caused by new mobile masts being upgraded in the area. However, there are many different factors such as the weather or faulty aerials that can also cause interference. Our self-diagnosis tool is an easy to use, step-by-step questionnaire which can indicate whether or not the TV interference you are experiencing is being caused by a nearby mobile mast that has been upgraded. If at the end of the questionnaire you’d like further help and advice, please contact us.
There are 8 questions which should take less than five minutes to complete.
