Power cycling your LG TV is the most popular and effective solution for clearing temporary glitches preventing your TV from turning on. A power cycle clears up any excess charge that may have built up over time, thus enabling your LED TV to turn on.

This solution also applies to resolving similar issues with other TV brands like Sony and Apple TV.

How To Power Cycle Your LG Television?

• Unplug the TV from the power source.

• Wait for a minute (don’t skip this and wait patiently)
• In the meantime, Press & hold the Power button on your TV for about 30 seconds (you can find the power button at the bottom or on the sides of the TV)

• Then plug your TV cable back into the wall socket

Check Your Connections:

If you are experiencing the LG TV won’t turn on, you must check that the cables (cable box) you use are connected correctly and tightly. 

Moreover, while looking at your cables, ensure there should not be any damage.

Sometimes, the source outlet may be damaged or faulty, resulting in the LG TV not turning on. In such cases, you can try plugging your LG TV into another power outlet you know is working.

To ensure the power outlet works, test it with another device before connecting your TV.

Check Your Sensors:

Another factor that can prevent your LG TV from turning on is the sensors on the TV and the remote control.
