A:AnswerThe free Roku app lets you control Roku TV from a phone or tablet with the same buttons you'll find on the standard Roku remote. This only works for Roku and its applications, not the enitre television.
A:AnswerTry resetting the tv. There is a very small hole in the back of the tv. With the tv on push a pin in the hole and the tv screen will tell you when the reset is going on. Good luck.
