Roku remotes cannot directly control the TV's input/source control. BUT, the TV itself may do this for you.
If your TV supports CEC (Consumer Electronic Control) over HDMI, turn on this feature in your TV settings if necessary. Unfortunately many TV manufacturers call this feature by their own proprietary names.
Some common ones:
• AOC: E-link
• Hitachi: HDMI-CEC
• LG: SimpLink or SIMPLINK (HDMI-CEC)
• Mitsubishi: NetCommand for HDMI, Realink for HDMI
• Panasonic: VIERA Link, HDAVI Control, EZ-Sync
• Onkyo: RIHD (Remote Interactive over HDMI)
• Philips: EasyLink
• Pioneer: Kuro Link
• Runco International: RuncoLink
• Samsung: Anynet+
• Sharp: Aquos Link
• Sony: BRAVIA Link, BRAVIA Sync, Control for HDMI
• Toshiba: CE-Link, Regza Link
Some other names shared by multiple manufacturers:
• Fun-Link, INlink, T-Link
On some TV's you may need to have the TV do a scan or search for connected CEC devices.
With CEC enabled on the TV, pressing a button on your Roku remote should switch the TV to the HDMI port to which your Roku is connected without you having to do it via the TV remote. To turn this feature on in your Roku, enable "1-touch play" via Roku menu path "Settings > System > Control other devices".
Note: If other connected devices (game console, cable box, disk player, etc) also have a CEC function, pressing a button on the their remotes may also switch the TV to their TV inputs.
