    Verify that the LG TV has its HDMI CEC (named SimpLink for LG) enabled in its Settings. (use your TV remote, not the Roku remote, to go into the LG settings to enable this.)

    Then go to your Roku device and Enable 1-touch play under Settings/System/Control other Devices/1-Touch Play/[checkmark to Enable]

    ----

    Once both the above are enabled, you should be able to press any button on your Roku remote (excluding the Power, Volume, Mute) in order to automatically and simultaneously wake the Roku device, turn your TV on, and switch to the appropriate HDMI input.

    THANK YOU!!!  This fixed a major headache for us -- which was that "every time we turned off our TV, and then back on again later, the LG TV would REVERT back to the WebOS home screen!"

    This would force us to pull out the TV Magic Remote, to reselect the ROKU!! (when we ALWAYS want it to be the ROKU, with few exceptions)

    So the:
    Settings => All Settings => General => System => Additional Settings => Home Settings => [TURN OFF ALL CHECKBOXES]

    Fixed this for us!   Now when we turn off the TV (using ROKU remote), it KEEPS the ROKU as Input! (and even preserves the show/channel we were watching!).

    So nice!  THank you for sharing this.

The link in your answer said to do this:

[All Settings] → [General] → [Devices] → [HDMI Settings] → [Simplink (HDMI-CEC)] → [ON].

I couldn't find that menu on my LG TV, but I did find it here:

Settings → Connection → HDMI Device Settings → Simplink (HDMI-CEC) → On

I don't know how it got turned to OFF, because it worked the way it was supposed to for a long time.  Maybe it was a firmware update?  Anyway, turning the setting to On fixed it!!!!  Thanks.
