I just purchased a new TV. Now the Roku remote turns the TV on, but not the powered Roku box. I have to unplug the Roku box and let it reboot every time. Any suggestions?
The power button on the remote is only for the TV. Roku devices never really turn off. Some have a "power saving" option under Settings->System->Power which, if enabled, will put the device in a "sleep" state. You can wake the device by pushing any non-TV control button. I'd suggest pressing Home a few times after you turn on the TV.
