Why Does LG TV Keep Restarting?

To be able to find remedies to any problem, it is essential to understand the root causes.

Below, we have briefly discussed all possible reasons that may result in your LG TV abruptly restarting.

Faulty/Loose Power Cables

The most common reason why LG TVs keep restarting is because of faulty or loose power cables.

Any problem in the power supply, power cables, or power outlet results in an unstable connection.

Any weakness or instability in the connection will always lead to restarting and might even result in failure to start.

TV Remote Issues

If your TV remote has low batteries, there is a high chance that your LG TV may reboot on its own.

With weak batteries, a remote may start sending random signals to your TV, causing an intermittent TV reboot.

Wrong TV Settings

TV also restarts on its own if any timer has been set in place in the system.

Many users forget after setting a timer on their TVs and later worry about the sudden restarts.

If the timer on your LG TV is set to “On” mode, your TV will automatically restart.

Conflicting Connected Devices

In some cases, the problem may lie in the devices connected to your LG TV rather than the LG TV itself.

Devices connected to your LG TV, either wirelessly or using a wired connection, could be interfering with your TV settings and consequently causing it to turn on and off.

CEC Settings

At times, the internal HDMI and CEC settings of your LG TV may turn the TV on and off on its own.

An error in the configuration of these settings could lead to abrupt restarting of your TV.

Motherboard Issues

Unfortunately, your LG TV may also be causing you these problems simply due to damage to the TV motherboard.

The motherboard is the core to your entire device; a problem in it will not let you enjoy your TV peacefully.

How to Stop LG TV From Restarting?

Now that we have understood the reasons that may make your LG TV turn on and off randomly, let us go through some easy and effective solutions.

Follow the steps below to troubleshoot and fix your LG Smart TV that automatically restarts.

1. Check Cables and Connections

First and foremost, check the cable connections and power connections of your LG TV.

Usually, the power outlet has small springs in the socket that can turn loose when you plug in the TV’s power cable.

Make sure that the wire is firmly plugged in to a fully functional power plug.

You must also ensure that the wire is not excessively bent or damaged.

In case your cable is faulty or broken, replace the cables and try using your LG TV.

You may also look into the power outlet in the house. Fluctuations in power could be causing your TV to turn on and off.
