What could cause my LG TV to turn on by itself?
The automatic power-up of your LG TV can be attributed to several factors, including settings configurations, software bugs, or even external devices. One common reason is the “Simplink” feature, which allows HDMI devices to communicate with one another. If another device connected to the TV is configured to send a signal, it can inadvertently turn on the TV.
Another potential cause may lie in the remote control or its batteries. A malfunctioning remote, such as a stuck button, can send power signals to the TV, causing it to turn on independently. Additionally, check if any smart home systems or devices linked to your TV might be activated and sending power-on commands.
How can I disable the automatic power-on feature?
To disable the automatic power-on feature, you can navigate to the TV’s settings menu. Start by selecting the “Settings” option on your remote, then go to “General.” Look for “Simplink (HDMI-CEC)” and turn this feature off, as this is often responsible for the TV turning on when an HDMI device is powered up.
In addition to the Simplink setting, you can also check for any “Wake on LAN” or related settings from external devices. By disabling these features, you reduce the chances of your LG TV spontaneously turning on when other devices in your home network are activated.
Could a software update resolve this issue?
Yes, a software update could potentially resolve the issue of your LG TV turning on by itself. Manufacturers frequently release firmware updates that include bug fixes, security patches, and improvements in overall performance. If your TV’s software is outdated, it might exhibit strange behaviors, including the automatic power-up feature.
To check for a software update, navigate to the “Settings” menu, and select “All Settings.” From there, go to “About This TV” and look for the “Software Update” option. If an update is available, it is recommended to install it to see if it helps with the issue.
What is the role of connected devices in this issue?
Connected devices play a significant role in the automatic powering on of your LG TV. Features like HDMI-CEC allow connected devices, such as Blu-ray players or gaming consoles, to communicate with the television over HDMI. This can sometimes lead to the television turning on when the connected device is powered up, even if you have not manually turned on the TV.
If you suspect that a connected device is causing the problem, try disconnecting HDMI devices one by one to see if the issue persists. You may also need to investigate the settings of each connected device to ensure none are set to automatically power on the TV when they are activated.
Is there a hardware issue that might cause this problem?
While software issues and settings are the most common culprits behind a TV turning on by itself, hardware malfunctions can also be responsible. If the power button on the TV is jammed or if there’s an internal glitch, it may cause the TV to turn on at random times. This is less common but worth investigating if other solutions do not resolve the issue.
If you suspect a hardware issue, you may want to perform a reset of the TV. Refer to the user manual for specific instructions. If the issue persists after the reset and troubleshooting, it may be advisable to consult a professional technician to diagnose and repair potential hardware problems.
Can my LG TV be affected by a power surge?

Check if any buttons, particularly the power button, are jammed or excessively worn. Replacing the batteries with new, quality ones can also rule out battery-related issues.
Additionally, if your remote has a programmable feature or can be connected to smart devices, there may be a possibility of remote interference. To troubleshoot this, you could remove the batteries and observe if the TV still turns on by itself. If the problem persists, the issue may be more complex than the remote control.
Should I factory reset my LG TV to fix this issue?
Performing a factory reset on your LG TV can be an effective solution if you’ve tried other troubleshooting options and the TV continues to turn on by itself. A factory reset will return all settings to their original state, potentially eliminating any misconfigurations or problematic settings that may be triggering the issue.
Before proceeding with a factory reset, make sure to backup or note down any personalized settings and preferences. To do a factory reset, go to the “Settings” menu, select “All Settings,” then go to “General” and find “Reset to Initial Settings.” Follow the on-screen instructions, and once the reset is complete, monitor if the issue persists in the following days.
