LG TV IR Sensor Location varies depending on the model.
In general, the light sensor on an LG TV is located on the front part of the TV, near the power button or the logo.
However, some models may have different locations, such as the bottom right corner, the bottom left corner, or slightly to the left of the power button.
In this article, I will break down the locations depending on different models and show you how to clean/replace it if you think it’s damaged.
Let’s dive in…
How To Locate LG TV Light Sensor
Locating the light sensor isn’t that easy.
For this, I developed the following two methods that work in almost all cases.
- Use a good camera with a good flash and take a picture of the front part of the TV where the IR sensor should be. The flash will cause the IR sensor to show up as almost purple compared to the black bezel.
- Use another remote control that works with infrared signals and point it at different parts of the front part of the TV while pressing a button. When you find the spot where the remote works best, that’s where the IR sensor is located.
To give you some examples, here are some specific locations of the IR sensors on some popular LG TV models:
1) LG CX IR sensor location
The LG CX is one of the most popular OLED TVs from LG. It has a sleek design with a thin bezel and a minimalist stand.
The IR sensor on the LG CX is located on the bottom center of the TV, right above the power button. (Look at the above picture)
2) LG C1 IR sensor location
As you can see in the above picture, the IR sensor on the LG C1 is also located on the bottom center of the TV, but slightly to the left of the power button.
How To Replace LG TV IR Sensor
First, turn off and then disconnect the TV from the power outlet.
Open the TV’s back panel and locate the IR sensor board. It’s usually positioned on the front of the TV, either in the middle or off to one side.
If necessary, remove the bezel or cover that surrounds the screen to access the IR sensor.
Once you locate the IR sensor board, disconnect all the ribbon cables connected to it and then place the new IR sensor that you have already purchased.
Connect the new sensor using wires or solder it onto the board, following the same connections as the original sensor.
Put everything back together in the reverse order of disassembly. Make sure all screws are securely tightened, and the bezel or cover is properly reattached.
How to Fix Common Issues With The IR Sensor?
You are locating the IR Sensor, which means there is definitely an issue you are having.
Maybe your TV isn’t responding to the remote because the TV’s IR sensor is dusty, and you want to clean it, or maybe it’s damaged, and you are trying to replace it.
Well, before you go to replace the IR sensor, I recommend checking the following two steps first and then proceeding to the third step.
1) Remote not working or responding
In general, if your remote is not working or your TV isn’t responding to the commands, there are several possible causes and solutions:
- First, check the batteries of your remote. They may be low or dead, so replace them with new ones.
- Check the remote itself. It may be broken or damaged, so try using another remote that works with your LG TV or contact LG customer service for a replacement.
I’m sure you’ve already tried using new batteries.
Now, the next step is to press and hold any button on the remote.
Look for a faint pulse of light from the LED. It might be a bit hard to see, so you might need to go into a dark room. But if the LED pulses, that means the remote is working fine.
2) IR sensor blocked by an object
If your IR sensor is blocked by an object, such as a sound bar, glass, or another device, the remote signal may not reach it properly, and your TV may not respond.
Make sure no object is blocking the signal from the remote to the TV.
Try moving the TV to a different location where there is no obstruction. Or you can use an IR blaster to extend the IR signal (see below).
3) IR sensor damaged or faulty
Now if nothing works, IR sensor is definitely faulty.
Simply order a new one from Amazon or Shopjimmy.com and then replace it properly.
Q: Can sunlight or other strong light sources interfere with the IR sensor?
Yes, direct sunlight or strong ambient light sources can interfere with the IR sensor’s ability to receive signals.
If you find that the remote control is not working properly during the day, try adjusting the blinds or curtains to reduce the incoming light.
Q: How do I test if my remote control or my TV IR sensor is working properly?
To test if your remote control or your TV’s IR sensor is working properly, you can do one of these things:
First: Use another remote control that works with infrared signals and point it at your LG TV while pressing a button. If your LG TV responds, then your remote control may be faulty.
If not, then your IR sensor may be faulty.
Second: Use a good camera with a good flash and take a picture of the front part of your remote while pressing a button.
The flash will cause the infrared LED (a small light bulb) on your remote to show up as almost purple compared to the black body. If you see it light up, then your remote control is working.
If not, then your remote control may be faulty.
Third: Use a good camera with a good flash and take a picture of the front part of your LG TV where the IR sensor should be.
The flash will cause the IR sensor to show up as almost purple compared to the black bezel. If you see it, then your IR sensor is working.
If not, then your IR sensor may be faulty.
Q: Is it possible to disable the IR sensor on my LG TV for security reasons?
LG TVs do not have a built-in option to disable the IR sensor completely.
The IR sensor is essential for remote control functionality.
However, if security is a concern, you can enable the TV’s built-in parental control features to restrict certain operations.
