TalkTalk have no control of your reception.
You can check if there is any maintenance on your region transmitter by visiting the Freeview website.
Weather can affect the signal too so try a Google search for TV signal weather issue in xxx to see if anything is happening.
Is your TV signal ok if you plug the aerial directly into the TV bypassing the box?
If not you may have an aerial issue, in which case you will need to consult a local aerial installer to check your system.
Let us know how you get on and which box you have.
