Thank you for the update and for doing the checks.
If these have been checked as well as the other cables in the Tivo box and hub and the issue is still happening we would need to book an engineer visit for you.
To do so I do need to pass some security with you through a private message.
I will pop one over for you now, if you're ok to please go to the purple envelope in the top right to respond.
Thank you, Emily.
