LG is one of the leading digital television brands, and it is a fantastic smart product to have at home. However, many users have complained of their LG TV turning on by itself without even being switched on. This can get rather frustrating, so why does it do that?

The most common cause of an LG TV turning ON is that the TV’s internal “wake-up” timer was accidentally set to turn on.

So, if this happens to your LG TV, it does not mean it is broken. In most cases, it is a simple-to-fix problem that can be resolved in a few minutes. In this article, we will go deeper into why your LG TV turns on by itself and how you can stop this issue. Keep reading for detailed information and ways to solve this issue.

How to Stop Your LG TV From Turning on by Itself

There are a number of possible reasons why your LG TV is turning on by itself, from stuck power buttons to the TV requiring a reset. Thankfully, most reasons are easy to solve by yourself and do not require a professional servicing.

Here are the things that you can do to check in order to stop it from happening:

1. Check the Power Source

Your LG TV can turn on by itself due to power supply failure, power surge, or a faulty outlet.

Therefore,  you first need to unplug your LG TV and look closely at the power cable for fraying or damage. If you notice any damage, remove the cable safely and replace it. Otherwise, ensure the power cable is firmly connected to your TV.

There may also be an issue with the power outlet. So, try plugging your TV into different sockets. Additionally, if you have been using a surge protector, unplug your TV cord and directly connect it to the wall outlet.

2. Inspect your Remote Control

You should take a look at the power button of your remote control. For instance, it can be stuck due to spills of sticky stuff. Therefore, you can clean the remote control until all the buttons start working properly.

To do this, follow these steps:

Step 1: Remove the batteries from your remote control.

Step 2: Shake loose any dirt or debris between the remote buttons.

Step 3: Put rubbing alcohol on a soft cloth and wipe your remote control.

Step 4: Allow it to air dry.

You should also check and change the batteries. For instance, when the remote battery power is low, it can send a random signal to your LG TV, making it turn on by itself.

3. Check and Disable Your TV “Wake-UP” Timer

Wake-up timers are a great way to turn your TV on whenever necessary. However, if a family member sets it ON without informing you, you will be annoyed when the TV turns on by itself.

Therefore, you need to go to your TV’s settings and check the “wake-up” timer. If it is turned ON, disable it.

4. Check the CEC Settings

CEC is an acronym for Consumer Electronics Control. It is a feature that enables devices connected to HDMI ports to control your TV. For example, if you switch on the gaming console, CEC will turn on your TV. LG manufacturers refer to CEC as SIMPLINK.

Although this setting is helpful and convenient, it can sometimes act strangely and annoying. Therefore, you should disable CEC via your TV settings.

5. Disconnect Your LG TV From WiFi

If your LG TV is connected to an Amazon Echo or Alexa device, the voice commands may be causing the TV to turn on by itself. Therefore, disconnecting WiFi on your TV will stop any other app or program from controlling it.

6. Do a Factory Reset

If you have tried all the above tips and your LG TV is still turning on by itself, you should do a factory reset. It is vital to note that this will wipe out any app downloads or custom settings.

Here is how you can do it:

Step 1: Open the settings menu.

Step 2: Click “All Settings” > “Support.”

Step 3: Scroll down to “General.”

Step 4: Navigate to “Reset to initial settings” > “Confirm” and enter your password.

Your LG TV will shut down when it is done repairing itself.

Final Thought

Your LG TV turning on by itself is not something new. It is one of the usual things that has happened to most of us. Although you do not know what causes your LG TV to turn on itself, this article has given you the answers. For instance, the most common reason your LG TV turns on by itself is that the “wake-up” timer is set on.
