Someone may wonder, "My LG tv keeps turning off after 4 hours." Notably, one frequently asked question is, "Why does my LG OLED tv keep turning off?" 

If your LG TV turns off unexpectedly, it could be due to various factors. Below are some primary reasons why your LG TV keeps turning off.

Overheating

Overheating a television is caused by a combination of factors such as inadequate ventilation, high temperatures, and insufficient airflow around the TV. 

This can be especially problematic in enclosed spaces such as cabinets or entertainment centers. 

Power Cord Issues

One of the most common reasons an LG TV may keep turning off is an issue with its power cord. 

This could result from a faulty power cord, a power cord that needs to be appropriately connected, or a power cord misconnected to the proper outlet.

Faulty Cables

If your LG television is turning off unexpectedly, there may be an issue with the cables connecting the TV to the power source or other devices. 

Faulty wires result from problems such as poor quality, age, or physical damage. 

Software Issues

If your LG TV keeps turning off, it may be a software issue. 

Possible causes of the problem could be a software glitch, a problem with the TV's settings, or an issue with the TV's power supply.

Power Supply Issues

The reason could be a sign of a power supply issue. These issues generally result from a faulty or malfunctioning power supply responsible for supplying the TV. 

Auto Power

Auto Power is a setting that is enabled by default on many LG TVs, automatically allowing the TV to turn itself off after a predetermined period of inactivity.

This can be a helpful feature when it comes to saving energy, and however it can also be quite bothersome if you are in the middle of watching something and the TV shuts off unexpectedly. 

On Timer

Many LG TVs are available with an On Timer feature, which allows you to set a timer to turn off the TV automatically. 

This setting will enable you to set a specific time for the TV to turn off automatically. 

If this feature is enabled, it could be why your LG TV is turning off periodically. 

Broken Mainboard

A broken mainboard is one of the reasons

A broken mainboard is one of the reasons

The mainboard is the electronic circuitry that makes up most of the TV's internal components. 

It is responsible for powering the TV, processing audio and video signals, and maintaining the overall operation of the TV. 

If the mainboard is not functioning correctly, the TV will be unable to process the necessary signals and will shut off. 

How to Fix LG TV That Keeps Turning Off?

If your LG TV is turning off unexpectedly, there are a few methods you can take to try to resolve the issue. They are as follows:

Check for Loose Wires

If you are experiencing issues with your LG TV, such as the TV randomly turning off, check for loose wires. 

Start by unplugging the television and then examine the back of the TV to ensure all the cables are connected securely. 

If the cables seem loose, gently tighten them to ensure a proper connection. Also, inspect the interior of the TV for any damage. 

Check Power Source

Ensure that the power cord securely connects to the outlet and that the power outlet is functioning. 

Check the power cord for any damage if the outlet is working. If the line is damaged, you may need to replace it. 

Additionally, if you are using an extension cord, ensure that it is rated to handle the power required by the television.

Check for Firmware Updates

If your LG TV is randomly turning off, the solution is to check for any available firmware updates. 

Firmware updates help ensure that your LG TV is running the most up-to-date software, which can help fix any bugs or glitches causing the issue. 

Start by clicking the Home/Start button on your remote to check for firmware updates. After that, choose Settings>All Settings>General>About this TV>Check for updates here.

Check Settings for Power Saving Mode

If your LG TV keeps turning off, you'll want to check the settings to ensure that the power-saving mode is not enabled. 

To do this, start by accessing your TV's settings. 

We can do this by pressing your remote's Home/Start button. Then choose Settings>General > Additional Settings>Eco Mode>OFF.

Reset TV

If your TV isn't functioning correctly, trying a reset is valuable in fixing the problem.

Below is how to factory reset your LG television.

Step 1: Press the power button to shut off the set.

Step 2: It's time to unplug the appliance from the wall. Unplug it for a full minute.

Step 3: Connect the TV again.

Step 4: Push the power button to turn it back on.

Disable the Auto Power Off

If your LG TV keeps turning off, you can resolve the issue by disabling the Auto Power Off feature.

This feature automatically turns off the TV after a certain period of inactivity. You can disable it by pressing the HOME button on your remote.

> SETTINGS >GENERAL >TIME >TIMER >AUTO POWER OFF.

Disable the Power Off Timer

Using the device's built-in power-off timer, we can program an LG television to power down automatically at a predetermined time of day.

Once the daily time has passed, the TV will automatically power off. If you were not actively viewing TV at the time, this would turn it off. 

This option may have been selected and activated by mistake. 

If you want to turn off the power timer, follow these instructions: Press the HOME button on your remote>SETTINGS>GENERAL>TIME>TIMER>POWER OFF TIMER.

Contact the Manufacturer for Technical Support
