While setting up to cast YouTube from my phone to my Samsung smart TV I entered 'deny' instead of 'allow' on the TV by mistake. Now when I try to cast, the TV doesn't give me the options and I can't cast to it anymore. How do I reset the TV to change back the settings please?
OK. To carry out a reset, go to Home > Settings > Support > Self Diagnosis > Reset. Note, any changes you may have made to your settings will revert to the default settings.
Let us know how you get on, @KenB44.
