Connect a Roku Remote to an LG TV for Power and Volume Control

The practical route for how to connect Roku remote to LG TV control is to start with a supported Roku voice remote that already navigates its Roku player, then run Set up remote for TV control from Roku's Remotes & devices settings. That routine identifies a compatible command path for television Power and volume. It does not turn the Roku handset into a full LG webOS remote. A remote TV app remains better suited to LG menus and app navigation, while the Roku remote handles streaming plus the limited TV keys it actually provides.

Confirm that the handset has television keys

Look for Power, volume, and mute buttons and identify the remote in Roku settings. A simple Roku remote without those keys cannot gain them through software. Make sure Home and directional controls already operate the intended Roku device. If they do not, solve remote-to-player pairing first. Also identify the actual sound destination: TV speakers, soundbar, or AV receiver. A setup that sends volume to the television will appear to fail when audio has been routed elsewhere.

Open the current TV-control flow

Press Home on the working Roku handset, go to Settings, choose Remotes & devices, select Remotes, choose the voice remote, and start Set up remote for TV control. Roku may update labels or screen order, so follow the visible prompts if wording differs. Keep the LG television on, remain on the Roku HDMI input, and reduce background sound. The process can play music and ask whether it stopped; answer based on what you actually hear, not what you expect the system to have done.

Complete the audio confirmation carefully

Allow the Roku device to determine the TV brand or command set, then respond to its test questions one at a time. If sound continues when the prompt expects silence, say so and let the flow try another profile. Do not press volume from the LG handset during the test, because that can produce a false confirmation. When setup completes, test volume up, volume down, mute, and Power using only the Roku remote. Repeat from the normal seating position to expose line-of-sight issues.

Understand infrared and CEC behavior

Television control can involve infrared commands from the Roku remote and, on supported equipment, HDMI-CEC behavior through the Roku player. LG generally calls its CEC option SIMPLINK. Infrared requires aim toward the TV; CEC travels through HDMI but must be supported and enabled along the chain. Some televisions support only portions of power or volume control. If performance changes when the player loses external power, check the power method and CEC path before reprogramming a remote that still navigates Roku correctly.

Fix the failing layer only

When Roku menus respond but LG TV keys do not, rerun TV-control setup and check speaker routing, infrared visibility, and SIMPLINK. When neither Roku navigation nor TV keys respond, recharge or replace batteries and repair the player pairing. When volume changes the TV indicator but not the actual sound, configure the soundbar or receiver according to its supported route. When Power works only at close range, clear the lower bezel and retest under normal lighting. Each pattern identifies a narrower cause than starting over with every device.

Keep full LG navigation on a separate controller

For input changes or webOS settings beyond the Roku handset, open the verified iPhone store page and download remote TV app once local connectivity is confirmed. Name the LG set by room to avoid selecting a second television. Keep the phone still while grading the Roku remote, then use it only for the missing LG-specific task.

Set expectations for a two-remote system

A successful Roku connection commonly provides streaming navigation plus LG Power and volume, not every television command. Retain an LG-compatible controller for inputs, channels, picture settings, accessibility, and advanced menus. Write down the Roku player, voice remote, LG model, audio device, and whether control uses infrared, CEC, or both. Label the HDMI input and store the LG controller in a consistent place so guests do not rerun setup when they only need an input change. Ask another household member to begin a viewing session from standby and confirm that audio reaches the intended speakers. Test again after moving the player or changing the sound system. If performance becomes intermittent, note whether the remote was aimed at the TV or the player; that detail helps separate infrared from Roku navigation. Clear roles make the setup feel simple even when two controllers remain necessary.
