LG TV IR Blaster: Setup and Usage Guide

The IR Blaster on LG TVs is a powerful yet underrated feature that typically comes with LG C, G, and NanoCell models.

But did you know that almost 95% of users don’t even realize its full potential?

In simple terms, an IR Blaster lets you control multiple infrared remote-controlled devices—such as cable boxes, Blu-ray players, and stereo receivers—using your LG TV remote.

This guide will explain everything about IR Blasters, including setup, compatibility, and troubleshooting tips.

Let’s dive in!

What is IR Blaster on LG TV?

IR Blaster is just like a magic remote control sender!

It accepts commands from your remote and “blasts” them via infrared light to the device you want to control.

For example, if you want to control HDMI media content from a faraway location, the IR Blaster can help by sending the remote control signals from that location back to where you are, so you can control what you’re watching from a distance.

Another useful scenario is when you have a piece of audio-video equipment that you’d like to place inside a cabinet behind a closed door or in a wiring closet that’s out of sight.

In such cases, with the help of an IR blaster, you can still control the equipment even though you can’t see it.

That’s a great opportunity!

How To Use IR Blaster on LG TV

 

Here are the detailed guidelines:

Step 1: Plug the IR Blaster into the Port

The first thing you need to do is, locate the IR Blaster port!

It’s a small jack (similar to a headphone jack) usually found at the back or side of your LG TV. 

To find out if your LG TV has an IR blaster port, look at the back or side of your TV and look for a label that says “IR BLASTER” or “IR OUT”. (Look at the above picture)

Once you find it, simply plug it 

However, if there is no port labeled ‘IR Blaster” or “IR OUT“, try plugging it directly into the audio or Video port. This might also work.

Step 2: Place the Blaster Near the Remote Sensor of Your Device

Place the IR blaster near the IR sensor of the device you want to control with your LG TV’s remote control.

The remote sensor is usually a small window or a dot on the front of your device that receives the infrared signals from your remote control.

You need to place the IR blaster as close as possible to the remote sensor, but don’t cover it completely.

If you want, you can use adhesive tape or Velcro to secure it in place.

That’s it…

Step 3: Check If the IR Blaster Is Working Properly

The last thing you need to do is to check if the IR blaster is working properly and sending the correct commands to your device.

To do this, press the Home button on the remote and then go to Settings > General > External Device Manager > Device Connector > Set-Top Box > Test Remote Control.

Then, follow the instructions on the screen and see if you can change channels, adjust volume, and access menus on your device using your LG TV’s remote control.

F.A.Q.s

Q: What is the difference between an IR blaster and a universal remote?

An IR blaster is a device that sends infrared signals to another device, while a universal remote is a remote that can control multiple devices with different infrared codes.

An IR blaster can extend the range of your universal remote or allow you to use your LG TV remote as a universal remote.

Q: Can I use an IR blaster with any LG TV model?

Not all LG TVs support IR Blasters.

• Check the back or side of your TV for an IR Blaster port.
• If there’s no port, you might need an external IR adapter that connects via HDMI, USB, or Wi-Fi.
