@Tee2 All of your TV settings will get deleted, except for your Network settings. Do let us know how you get on.

Alright, have you also tried resetting the Smart Hub? Menu > Settings >  Support > Self Diagnosis > Reset Smart Hub. If you keep having issues, it may be best to get in touch with Samsung AV and TV support specialists via Live Chat.
