How do I exit out of Roku back to my regular TV. Can you go back and forth between the two?
Is this a roku device with a regular TV or a Roku TV? With the former, you just switch the input back to where it was.
It is a regular TV. Where do I find "input" to change it?
On your TV's remote control. The button may be labeled "Input" or "Source" or "A/V"...
