YouTube is not working properly, possibly because my YouTube account is banned. Anyway, the screen remains empty and I can't navigate to the settings to sign out, so I can sign into another account. How can I fix this? I've been googling how to uninstall/reinstall an app on my tv, but so far no luck. Failing that I need to know how I can sign out of my old banned account so I can sign into a new one. It seems like I can't actually get to the YouTube seem settings menu, because the current account is banned and the tv therefore cannot access the menu??? Anyway, however I can tux this ??? Please help.
