Are you talking about a smart TV or the TV hub or other box supplied by TalkTalk? Do you get any errors messages?
You could try
Checking for updates on the device
Rebooting the router
Forgetting the network on your TV or box.
Disconnecting the TV or box from the mains and restarting.
If its the Hub or 4k box, resetting this to factory settings (you will have sign into apps again).
Check your TV manual on the manufacturers website on how to reset the TV.
Hope this helps.
