@DJSkow, since you don't give many details, I have to make a few assumptions. It sounds like you have a Roku device connected to the TV and you're pressing the Power button on the Roku remote. Note that the Power button is strictly for the TV. Roku devices don't turn off. Your Roku device may have a "power saving" feature enabled (not all Roku devices have this feature). To wake it up, you can press any non-TV control button on the Roku remote or you can disable the feature under Settings->System->Power. If my assumptions are wrong, please give more details.
