Are you experiencing the frustrating issue of your LG TV turning on by itself? This phenomenon can be both puzzling and annoying, especially if it happens in the middle of the night or when you’re not even in the room. In this article, we’ll delve into the possible causes behind this issue and provide you with practical solutions to resolve it.
Common Causes of LG TV Turning On By Itself
Before we dive into the solutions, it’s essential to understand the common causes of this issue. Here are some possible reasons why your LG TV might be turning on by itself:
1. Power Button Issues
One of the most common causes of an LG TV turning on by itself is a faulty power button. If the power button is stuck or malfunctioning, it can send a signal to the TV to turn on, even when you’re not pressing it.
2. Remote Control Issues
Another possible cause is a faulty remote control. If the remote control is sending a signal to the TV to turn on, even when you’re not pressing any buttons, it can cause the TV to turn on by itself.
3. Smart TV Features
LG TVs come with various smart features, such as voice control and gesture control. These features can sometimes cause the TV to turn on by itself, especially if they’re not configured correctly.
4. HDMI-CEC Issues
HDMI-CEC (Consumer Electronics Control) is a feature that allows devices connected to your TV to control it. However, if there’s an issue with the HDMI-CEC connection, it can cause the TV to turn on by itself.
5. Firmware Issues
Firmware is the software that controls your TV’s functions. If there’s an issue with the firmware, it can cause the TV to malfunction, including turning on by itself.
6. Power Supply Issues
A faulty power supply can also cause your LG TV to turn on by itself. If the power supply is not providing a stable voltage, it can cause the TV to malfunction.
Troubleshooting Steps to Resolve the Issue
Now that we’ve identified the possible causes, let’s move on to the troubleshooting steps to resolve the issue. Here are some steps you can follow:
Step 1: Check the Power Button
The first step is to check the power button on your TV. Make sure it’s not stuck or malfunctioning. Try pressing the power button a few times to see if it’s working correctly.
Step 2: Check the Remote Control
Next, check the remote control to ensure it’s not sending a signal to the TV to turn on. Try removing the batteries from the remote control or covering the IR sensor to see if it resolves the issue.
Step 3: Disable Smart TV Features
If you suspect that smart TV features are causing the issue, try disabling them. Go to your TV’s settings menu and disable features like voice control and gesture control.
Step 4: Check HDMI-CEC Connections
If you have devices connected to your TV via HDMI, try checking the HDMI-CEC connections. Ensure that the devices are not set to control the TV.
Step 5: Update Firmware
If you suspect that firmware issues are causing the problem, try updating the firmware. Go to your TV’s settings menu and check for firmware updates.
Step 6: Check Power Supply
Finally, if none of the above steps resolve the issue, try checking the power supply. Ensure that the power supply is providing a stable voltage.
Advanced Troubleshooting Steps
If the above steps don’t resolve the issue, you may need to perform some advanced troubleshooting steps. Here are some additional steps you can follow:
Step 1: Check for Loose Connections
Check all the connections to your TV, including HDMI cables, USB devices, and antenna connections. Ensure that all connections are secure and not loose.
Step 2: Check for Interference
Interference from other devices can sometimes cause your TV to turn on by itself. Try moving other devices away from your TV to see if it resolves the issue.
Step 3: Check for Firmware Corruption
Firmware corruption can cause your TV to malfunction. Try resetting the firmware to its default settings.
Step 4: Check for Hardware Issues
If none of the above steps resolve the issue, it’s possible that there’s a hardware issue with your TV. Try contacting LG support for further assistance.

What are the common causes of an LG TV turning on by itself?
There are several reasons why an LG TV may turn on by itself, including external device connections, internal TV settings, and environmental factors. External devices such as gaming consoles, DVD players, or soundbars connected to the TV via HDMI cables can sometimes cause the TV to turn on automatically. This is often due to the device’s power settings or a malfunction in the device itself.
Internal TV settings, such as the “HDMI-CEC” (Consumer Electronics Control) feature, can also cause the TV to turn on by itself. This feature allows devices connected via HDMI to control the TV’s power state. Additionally, environmental factors like a power surge or electrical interference in the home can also cause the TV to turn on unexpectedly.
How do I troubleshoot an LG TV that turns on by itself?
To troubleshoot an LG TV that turns on by itself, start by checking the external devices connected to the TV. Try disconnecting all external devices and see if the issue persists. If the issue stops, then it’s likely caused by one of the external devices. You can then reconnect each device one by one to identify the problematic device.
If the issue persists after disconnecting external devices, check the TV’s internal settings. Ensure that the “HDMI-CEC” feature is disabled, and also check the TV’s power settings to ensure that it’s not set to turn on automatically at a specific time. You can also try resetting the TV to its default settings to see if that resolves the issue.
Can a faulty remote control cause an LG TV to turn on by itself?
Yes, a faulty remote control can cause an LG TV to turn on by itself. If the remote control is malfunctioning, it can send incorrect signals to the TV, causing it to turn on unexpectedly. This can be due to a faulty button or a low battery level in the remote control.
To troubleshoot a faulty remote control, try removing the batteries from the remote control and see if the issue persists. If the issue stops, then it’s likely caused by the remote control. You can also try replacing the batteries or resetting the remote control to its default settings. If the issue persists, you may need to replace the remote control.
How do I disable the HDMI-CEC feature on my LG TV?
To disable the HDMI-CEC feature on your LG TV, go to the TV’s settings menu and select “HDMI Settings.” Look for the “HDMI-CEC” option and set it to “Off.” This will prevent devices connected via HDMI from controlling the TV’s power state.
Note that the exact steps to disable HDMI-CEC may vary depending on the LG TV model. You can refer to the TV’s user manual or contact LG support for specific instructions. Disabling HDMI-CEC may also affect the functionality of some devices connected to the TV, so be sure to check the device’s documentation before making any changes.

To check for software updates on your LG TV, go to the TV’s settings menu and select “Support” or “Software Update.” Follow the on-screen instructions to download and install any available updates. Note that the TV must be connected to the internet to receive software updates. If the issue persists after updating the software, you may need to try other troubleshooting steps.
