What are the common reasons my LG TV turns off by itself?

One common reason an LG TV may turn off by itself is due to power supply issues. This might involve a loose power cable or an unreliable power outlet. Ensuring that the power cable is securely connected to both the TV and the wall outlet can often resolve this issue. Additionally, trying a different outlet can help determine if the original one is causing the problem.

Another potential cause could be related to software settings, such as the sleep timer feature. If the sleep timer is activated, the TV will automatically turn off after a specified duration. Check the settings menu to see if this feature is enabled, and adjust it accordingly to prevent your TV from shutting off unexpectedly.

How can I troubleshoot my LG TV that keeps shutting off?

To troubleshoot your LG TV that keeps shutting off, start by checking the power connection. Make sure the power cord is firmly connected to both the TV and the wall socket.
