LG TVs are well-known worldwide due to their excellent picture quality, innovative features, and affordable prices.

However, some LG TV owners have reported a problem with their TVs turning on by themselves, which can be quite frustrating and disruptive.

In this article, we will explore the possible reasons why LG TVs turn on by themselves and what can be done to fix this problem. 

Reasons Why LG TV Turns On ItselfExplanation
CEC or HDMI-CEC CEC or HDMI-CEC (Consumer Electronics Control) is a feature that allows various devices connected through HDMI to communicate with each other. This feature enables users to control multiple devices with a single remote control. However, this feature can also cause LG TVs to turn on by themselves. If a device connected through HDMI-CEC sends a signal to turn on, the TV will automatically turn on. 
Sleep Timer If this feature is not set correctly or is malfunctioning, the TV may turn on by itself. For instance, if you set the Sleep Timer to turn off the TV after 30 minutes, but the TV turns on by itself after 20 minutes, it indicates a problem with the Sleep Timer feature. 
Power Outages When the power comes back on, the TV may turn on automatically if it was left in the state before the power outage. This is because the TV may register the power outage as an interruption in its functioning and try to resume its last state when the power comes back on.

Possible Reasons for LG TV Turning ON By Itself 

CEC or HDMI-CEC 

CEC or HDMI-CEC (Consumer Electronics Control) is a feature that allows various devices connected through HDMI to communicate with each other.

This feature enables users to control multiple devices with a single remote control. However, this feature can also cause LG TVs to turn on by themselves. If a device connected through HDMI-CEC sends a signal to turn on, the TV will automatically turn on. 

For instance, if you have a soundbar or a gaming console connected to your LG TV through HDMI, it might send a signal to the TV to turn on when you turn on the soundbar or gaming console. This can be quite frustrating, especially if you’re not planning on using the TV at that time.

Sleep Timer 

The Sleep Timer feature on LG TVs allows users to set a specific time for the TV to turn off automatically.

However, if this feature is not set correctly or is malfunctioning, the TV may turn on by itself. For instance, if you set the Sleep Timer to turn off the TV after 30 minutes, but the TV turns on by itself after 20 minutes, it indicates a problem with the Sleep Timer feature. 

Power Outages 

Power outages can also cause LG TVs to turn on by themselves.

When the power comes back on, the TV may turn on automatically if it was left in the state before the power outage. This is because the TV may register the power outage as an interruption in its functioning and try to resume its last state when the power comes back on. 

Firmware Updates 

Firmware updates are essential to keep LG TVs running smoothly and efficiently.

However, if the TV is set to automatically update the firmware, it may turn on by itself to complete the update process. This is because the TV needs to be on to download and install the firmware update. 

Faulty Remote Control 

A faulty remote control can also cause LG TVs to turn on by themselves.

If the remote control sends a signal to the TV, even if it’s not being used, the TV may turn on. This can happen due to various reasons, such as a stuck button or a malfunctioning sensor on the remote control. 

Faulty Power Button 

If the power button on the TV or remote control is stuck or malfunctioning, it may cause the TV to turn on by itself.

This is because the TV may register the button press as a signal to turn on and start functioning accordingly. 

Signal Interference 

Signal interference can also cause LG TVs to turn on by themselves.

If there are other electronic devices nearby that emit signals on the same frequency as the TV, it may cause the TV to turn on. For instance, if you have a microwave oven or a wireless router near your LG TV, it might interfere with the TV’s functioning and cause it to turn on by itself.

How to Fix LG TV Turning ON by Itself?

Disable CEC or HDMI-CEC 

To disable CEC or HDMI-CEC, go to the TV’s settings and navigate to the HDMI-CEC option.

Then, turn off the feature or select the option to disable it. By doing so, you will prevent other devices connected to the TV through HDMI from sending signals to turn on the TV. 

Check Sleep Timer Settings 

If the Sleep Timer feature is causing the TV to turn on by itself, check the settings and make sure it’s set correctly. If it’s not set correctly or is malfunctioning, tries resetting it or turning it off altogether. 

Unplug the TV 

If none of the above methods work, try unplugging the TV from the power source and leaving it unplugged for a few minutes. Then, plug it back in and turn it on to see if the problem persists. 

Check for Firmware Updates 

If the TV is set to automatically update the firmware, it may turn on by itself to complete the update process.

To prevent this, check for firmware updates manually and update the TV firmware when it’s convenient for you. 

Replace the Remote Control 

If the remote control is causing the TV to turn on by itself, replace it with a new one or try removing the batteries and using a different remote temporarily to see if the problem persists. 

Check Power Button 

If the power button on the TV or remote control is stuck or malfunctioning, it may cause the TV to turn on by itself. Try cleaning the power button or replacing the remote control or TV if necessary. 

Reduce Signal Interference 

If signal interference is causing the TV to turn on by itself, try moving the TV away from other electronic devices that emit signals on the same frequency. Alternatively, try using shielded cables or filters to reduce signal interference.
