LG TV Won’t Turn ON – Troubleshoot And Diagnosis

LG TV Won't Turn ON

When your LG TV won’t turn on, the problem could be a low power supply. You can tell if this is the case by testing your TV’s cables for continuity — or using an outlet tester to ensure it’s getting power. If there is a problem with the outlet, you can try plugging your TV into another one to see if it turns on.

Your TV is on the fritz, but don’t worry! You’re not alone — it happens to the best of us. And we’re here to help.

It’s possible that the power cable can be broken if it’s pulled too much or bent in a way that stresses the cable. This may cause the TV to not turn on, or it may cause an error message to appear.

Low voltage is one of the most common problems that can affect almost anyone who owns a smart TV. The best way to resolve it is to ensure the voltage is balanced — otherwise, you may have to call an electrical professional to make the necessary changes.

Motherboard issues can be caused by physical damage to the hardware. If your motherboard is damaged and you need a replacement, that’s okay — if you have a lot of time on your hands, you could take the old one out and replace it with a new one.

There’s a little-known issue that pops up when your TV’s firmware is out of date and the new updates haven’t been installed. This problem could also be caused by old files on your TV’s hard drive, corrupted files or even a virus on your system — all this can be removed with an expertly made update.

Here are some of the tried and tested methods to fix the LG TV won’t turn on issue. Follow these instructions in order to fix the problem out.

1. Inspect Power Cable

You might have a problem with your TV’s power cable or its connection to the wall. If you’re not getting any picture on your TV, you should check the following:

Make sure that the cord isn’t damaged anywhere. Look for any exposed cords or parts and try plugging it into another outlet. If it still doesn’t work, replace it.

Check the wall socket where you’re plugging in your TV’s power cable: make sure it’s not damaged, and that it’s securely plugged in. Check for damage to the TV’s power cable or for exposed wires. Finally, make sure the outlet is on — sometimes this can be the problem.

Any exposed wire on the LG television cable? You should plug it securely into an outlet. If the cable is not plugged securely, you may risk having problems with your TV. It’s smart to replace the damaged cable with a new one.

2. Check The Wall Outlet

If a smart TV is not powering up, the first thing to do is check the power cable. If there are issues with the cable or no electricity running through the wall outlet into which it has been plugged, it can be replaced. If there is still no power, make sure that the wall outlet that comes with fresh electricity running through it. If there’s an issue with a wall outlet, it can be replaced.

Check the other devices on the same wall outlet. If they are getting power, then the problem is with the TV itself.

If the TV works, it means there is an electrical problem with the wall outlet. Call a technician to fix it.

3. Do A Power Reset

If your LG smart TV is unresponsive, try the most obvious solution: unplugging it from the wall for about 60 seconds and then plugging it back in. Additionally, make sure that it is plugged directly into a wall outlet rather than into a surge protector or power strip.

It can be easy to get frustrated when your LG TV won’t turn on — especially if it happened in the middle of an important event. You know this is an emergency problem that needs fixing now. But there’s no need to panic or rush. The first thing you should do is unplug the TV from the wall socket and let it sit for at least one minute.

f your TV is unplugged, find the power button on your TV and hold it for 30 seconds. Make sure you are keeping your finger on the power button on your TV, and not the remote.

When you turn your LG TV off, make sure to unplug the power cord for about a minute. This will help drain any residual electricity from the TV and allow it to shut down properly. Unlike a remote reset, it’s important to make sure there is no electricity going through the TV before you turn it back on.

We hope this 60-second trick works for you and your LG TV! If you get it to turn back on, great! However, don’t worry if it doesn’t work. There’s more that you can do to get your TV back up and running. Check out the fixes below to see if any of these ideas could help you.

4. Check the Remote IR sensor

If the TV is blinking but not turning on, it means that you need to clean the remote control.

The only thing you need to make sure is that the smart TV remote is clean. The new one might have some kind of film or dust on it, so you have to clean it before pressing any button on the remote.

If the TV won’t turn on when you press the power button on the remote, it may be because it’s not receiving these signals. If this is your case, you’ll need to clean the upper part of the TV’s remote.

If the IR sensor is blocked on your TV remote control, it won’t be able to communicate with your TV. A dirty or dusty remote control can lead to missed commands, causing frustration during watching TV. Cleaning the remote with a microfiber cloth will ensure that you’re always in control.

5. Ensure That TV is not In Standby Mode

LG TVs come with an energy-saving mode that needs to be switched on. When the TV is in standby, it uses up very little electricity.

The standby mode also turns off your TV when it’s not in use, meaning you can’t really turn it back on unless you re-activate the standby mode.

In this case, you’ll want to first turn off the standby mode. To do this, locate the Off button on your smart TV remote. Then, press the Off button again and hold it for five seconds. Next, use the back arrow to navigate over to Main Menu > Setting > General > Power > Set Standby Mode to Off.

You can turn your TV on by removing the power outlet from the wall, plugging in the power cable, and turning it back on.

6. Update your LG TV

Sometimes, smart televisions can be difficult to update. For instance, sometimes you’re not even sure where to begin. The answer to this problem is simple: use a USB drive! To get started, take a look at your manual again and find the ports. Plug in your USB drive into the appropriate port on your TV and follow the instructions on your screen.

Although a smart TV is an innovation you should explore, it can take a lot to set up. The process usually involves downloading firmware from the LG website and then copying it onto a USB drive on your computer. You also have to insert the flash drive into your TV and then follow the on-screen prompts that lead you through completing the update.

7. Backlight is Broken

If the backlight of your TV is broken, you are not alone. Many people who own LG TVs have had the same problem. If this is the case for you, then there’s a solution.

To test this, power on your TV and then take a flashlight and bring it very close to your TV screen. If you’re not able to see the light shining through at all, then it’s possible that the backlight is broken.

You can check if your TV’s backlight is working: turn on the TV and then flash the light at the screen. If you see a faint picture that appears and disappears, it means that the backlight of your TV has failed and needs to be replaced.

8. Faulty Motherboard

If you hear a popping sound and see some sparks, then chances are you have lightning damage. The lightning did not only damage your LG TV, but also your TV’s motherboard. When this happens, it can be tempting to try fixing the board yourself. However, most people decide to take it in for professional repair instead.

If you suspect that the TV is experiencing an issue in its motherboard, then you can try to isolate where the issue is. The easiest way to do this is to turn on your TV and plug it into your AC wall socket. Once the TV is on, detach the cable that links the motherboard to the power board. If the TV still lights up, then you know that the power board is fine, and your issue lies in the motherboard.

TV Motherboards can be replaced at home, but you need to make sure you get the exact replacement part. If you’re not comfortable replacing it yourself, I suggest contacting a local TV repairman to help you.

9. Take Help Of A Repairman

For the majority of tech issues you might run into, there are many ways to troubleshoot and fix the problem immediately. But if your problem isn’t that easy to solve, don’t panic — there are lots of options. First, try troubleshooting the device yourself by following the manufacturer’s instructions.

If none of the troubleshooting methods work, it’s time to get your TV repaired. The motherboard or another internal part may be damaged, but this is easily fixed by LG customer service.

LG has a team of smart TV experts available for consultation, repair and service. LG monitors the quality of its products all the way from manufacturing through to end-user delivery.
