Change input on Hitachi LCD TV model LE65K6R9 without remote?
I'd unplug/disconnect the Roku and after 30 seconds try the control button on the back. If you can change the input do so, then plug the Roku back in. Until you use the input button on the back to change input to Roku, you should be able to use the other buttons on the back to control the TV. If this does not work, unplug both the TV and the Roku. Wait maybe a minute, then plug the TV back in and follow the above instructions. Here are other alternatives: Using physical buttons: You can find the physical buttons on the left or right back side of the Hitachi TV. Using these keys, you can change the input, adjust the volume, or turn on Hitachi TV without a remote. Press the Input button located at the back or side of the Hitachi TV. The list of connected sources will appear on the TV screen12.
Using external devices: Connect a wireless keyboard or mouse to your Hitachi TV and change the input1.
Buy a universal remote: You can buy a universal remote to control your Hitachi TV and change the source.
