An overview of the article.

1. Check the wall outlet.

Checking the power cable should be the first step taken if a Smart TV won’t turn on.

It can be replaced if the cable is broken or there’s no power coming from the wall outlet where it was plugged in.

Check to see if the wall outlet that came with the device has new energy flowing through it if there’s still no power. A wall outlet can be changed if there’s a problem.

Verify the other appliances are connected to the same wall outlet. If they’re receiving electricity, the TV itself must be the issue.

If the TV is operational, there is likely an issue with the wall outlet’s electrical system. Ask a professional to fix it.

2. Check the power cable.

The power cable might be damaged.

Your TV’s power cable or its connection to the wall may be malfunctioning. If your television isn’t showing any pictures, you should verify the following:

  • Verify that the cord is completely undamaged. Try connecting it to a different outlet while keeping an eye out for any exposed connections or components. Replace it if it doesn’t function any further.
  • Make sure the power cable for your TV is properly connected in and that the wall socket is secure before plugging it in. Look for exposed wires or damage to the TV’s power cable.
  • Finally, check to see if the outlet is turned on; occasionally, this can be the issue.

If there’s any exposed cable on the LG television, it should be safely plugged into an outlet. If the cable is not plugged in firmly, your TV could malfunction. It makes sense to swap out the damaged cable for a fresh one.

3. Try a power reset.

Try the most obvious fix first if your LG smart TV isn’t responding:

  • Disconnect it from the wall for around 60 seconds, then plug it back in.
  • Make sure it is plugged directly into a wall outlet as opposed to a surge protector or power strip.
  • When your LG TV won’t turn on, especially in the middle of a significant occasion, it might be simple to become frustrated. You are aware that this issue needs immediate attention as it is urgent. However, there’s no need to rush or panic.
  • Remove the TV’s power cord from the wall socket and leave it unplugged for at least a minute.
  • Find the power button on your TV and hold it for 30 seconds if it’s disconnected. Make sure your finger remains on the TV’s power button and not the remote.
  • Make sure to disconnect the power cord for roughly a minute after turning off your LG TV. This will assist in removing any remaining energy from the TV and enable a proper shutdown.
  • It’s crucial to confirm there is no electricity flowing through the TV before turning it back on, unlike with a remote reset.
  • We hope your LG TV and this 60-second trick work well together! It would be great if you could get it to switch on again. However, if it doesn’t work, don’t worry. There are more things you can do to reactivate your TV. See whether any of the fixes listed below can be applied to your situation.

4. Backlight is defective.

You are not alone if your TV’s backlight is damaged. Many LG TV owners have experienced the same issue. There is a remedy if this applies to you.

The backlight might be defective.
  • Turn on your TV, then hold a flashlight up to the screen of your TV to test this. It’s conceivable that the backlight is damaged if you can’t see any light coming through at all.
  • By turning on the TV and then flashing the light onto the screen, you can see if your TV’s backlight is functioning. Your TV’s backlight has failed and has to be changed if you notice a dim image that flashes on and off.

5. Motherboard failure

The motherboard might have defected

If you hear a popping sound and see sparks, you most likely have lightning damage. The lightning not only damaged your LG TV, but it also damaged the motherboard.

When this occurs, it may be tempting to attempt to repair the board yourself. Most individuals, however, choose to have it professionally repaired.

  • If you believe that the TV’s motherboard is malfunctioning, you can try to pinpoint the source of the problem.
  • The simplest method is to turn on your TV and plug it into an AC power outlet.
  • Detach the cable that connects the motherboard to the power board after the TV is turned on.
  • If the TV continues to light up, you know the power board is good, and the problem is with the motherboard.

TV Motherboards may be replaced at home, but you must use the correct replacement part. If you’re not comfortable fixing it yourself, I recommend hiring a local TV repairman.

Use the Services of a Repairman

You must contact the Repairman.

For the vast majority of IT difficulties, there are several techniques to diagnose and resolve the issue promptly. But don’t worry if your problem isn’t that simple to address.

There are plenty of choices. To begin, attempt to troubleshoot the item yourself by following the manufacturer’s instructions.

If none of the troubleshooting options work, your TV has to be fixed. The motherboard or another internal component may be broken, but LG customer care may readily repair this.

LG offers a team of smart TV professionals on hand to provide advice, repair, and service. LG closely oversees the quality of its goods from manufacture to end-user delivery.

  • Check that the plug is correctly attached to the outlet and that you are using an operational outlet. If the problem persists, you may have a faulty power supply.
  • If none of these solutions work and your TV continues to switch off, look for a blown fuse or a tripped circuit breaker. Contact a technician to confirm.
