Your LG TV might turn off due to loose power cables, damaged power sockets, outdated software, cache overflow, or even the auto power off feature on your TV. To solve this issue, you can try plugging the TV into a different socket, getting new power cables, or updating your TV’s firmware.

Although these fixes might seem simple at first, they can confuse the average person and leave them scratching their heads. Keep reading for a step-by-step guide on how to implement these fixes.

There are various reasons why your LG TV may have this issue. These may vary from hardware and software issues to simple problems such as a worn-out power cable. Nevertheless, below are some reasons that will help you determine why exactly your LG TV is shutting down.

Reason 1: Power Cables

The most common reason for LG TVs turning off without any apparent reason usually is a damaged power cable. If the wires have been subjected to any wear and tear it would hinder the power supply to the TV causing it to shut down.

You should check to see if you can see any clear signs of where the cable might have been damaged. The safest option is usually to buy new cables to ensure the issue is not in your cables.

Reason 2: Power Socket

Another reason why your LG TV is turning off could be that you’ve plugged it into a damaged power socket. Even if the power socket is suffering very small fluctuations in power, that is more than enough to force your TV to turn off.

To be certain that the problem lies in the power socket, you should plug your TV into a different socket. A decrease in the number of times it turns off without reason would suggest that the issue was with the original power socket.

Reason 3: Eco Mode

The eco settings on your TV, if turned on, will try to save power whenever possible, meaning it will turn the TV off if it feels like it is not in use. If you feel like this mode is turning off the TV even when you are using it, it might be because of a glitch, and it is best to turn the eco mode off.

Reason 4: Software

The next possible reason for your LG TV turning off while you are using it might be because of glitches in the older LG firmware. Since the firmware is what runs your TV, if it encounters any bug or glitch, it will definitely cause major performance issues. To avoid such problems, you will need to update the latest software available on your device.

Reason 5: Cache Overload

Caches are used by apps to minimize data retrieval time. It is usually created when you first download the app. However, as you download more apps, the cache memory will build up and cause your TV to run out of memory. This can cause your TV to be forced to shut down and restart in an attempt to clear up some memory.

To fix this, you can try deleting some of the apps that you do not use very often in order to clear up some memory. This will also allow for a smoother interface, and your TV will also stop glitching.

Reason 6: Overheating

This might be because of a lack of proper ventilation, which leads to your TV turning off to stop any major damage to the motherboard or internal hardware. The airflow is usually on the back of the TV, so to improve your TV’s airflow, you should ensure that nothing is blocking your TV from the back and clean it with a microfiber cloth in case of any dust.
