I have yet to read of another way. Even with Anymote I've heard yelps about certain things you need the TV remote for. This is one of them.
25 bucks to fix it seems. https://www.amazon.com/Samsung-Remote-Control-Originally-Shipped/dp/B01L19RB7S
I currently don't have a remote so I tried using the button the bottom right hand corner and I have limited options so I don't know how to get out of it.
