There is the gunck stuck on the outside of my TV screen. I have tried to clean it using my cleaning solution and it still wont come off. It seems the only way to get it off is to scratch it off but I'm too afraid to do that....please help
You're talking about a foreign substance sticking to the external surface of a Roku tv set? Roku only supplies the operating system for your set - the physical set itself is the responsinility of the set's manufacturer.
