Just for future issues with the TV and for any other users that are looking at this thread for TV help, I have a few links below that might help with general issues -
Our Service Checker is a good tool to use to check if there are any area outages ongoing with Broadband, TV, Landline and Mobile. It usually lets you know what is wrong and how long it's going to take for the engineers to fix (estimated time of course)
Your Online Account also has a good tool which helps diagnose a fault within your home network with your Broadband, TV and Landline, it will tell you what's up and what to do next.
We also have a good section for faults on our website here - Help Website- it will give you flows for diagnosing and rectifying faults on a multitude of aspects. A really good link to bookmark!
