I would suggest that you search for your TV model coupled with won't connect to WiFi to see if there are others who have similar issues as I suspect it is a TV issue rather than a router one if other devices connect.
First though double check you are using the WiFi password and not the router one as there are normally 2 distinct passwords printed on the reverse of the router.
