When I plug in my Roku Express, I can no longer change channels on the TV. If I hit the guide button or try to scroll up and down through the TV channels, I get sent back to the Roku channel. I am able to switch back to the TV by changing the input from HDMI 2 (the input for the Roku) to HDMI 1 and can view whatever channel the TV was last set to, but I can't change channels. How, other than unplugging the Roku each time I want to watch TV, do I address this issue? Thanks for your help.
Go into menu of the roku, settings> system> control other devices(CEC)> unclick 1-Touch play box
