Troubleshooting Guide: LG TV Won’t Turn On [9 Solutions]

If your LG TV won’t turn on after several attempts to press the power button on your LG TV remote, don’t panic. Generally, a TV refuses to turn on when there is an issue with the power outlet, remote control, or connected device. Certainly, the TV itself might also be blamed for LG TV not turning on, but that’s less likely. What’s the culprit that impedes your LG TV from turning on? Follow the troubleshooting guide to figure it out.

The post offers you 9 solutions to fix the LG TV not turning on, and during the fixing process, the culprit behind the issue in your case can be unveiled.

Fix 1. Check the Standby Light

If your LG TV doesn’t power on, first check the color of the standby light on the TV. The standby light might be located on the bottom center or bottom corners of your LG TV.

When the standby light is on, it has two colors. The red standby light indicates that the LG TV is turned off but plugged in, while the green standby light indicates that the LG TV is on. When the standby light is neither red nor green, it means that the standby light is off and the LG TV is not getting power at all.

In other words, if your LG TV won’t turn on but red light is on, it means that there might be an issue with your remote or the TV itself. If you see a green light on your LG TV, the TV probably has software or even hardware malfunction. If the standby light is off on your LG TV, there is an issue with the power supply.

Now you may have some clues about how to fix LG TV not turning on. If you are unsure of the solving process, please keep reading and refer to the following solutions.

Fix 2. Check the Power Supply

When a TV doesn’t receive power, any attmpt is useless. So, check if your LG TV is plugged into a power outlet (a wall electricity outlet is better in this case). If the power cord of your LG TV is snugly plugged into a power outlet but the LG TV doesn’t turn on, continue to check if the power outlet or the power cord works properly.

Fetch the power cord of your LG TV and inspect it. If the power cord gets damaged, it need to be repaired or replaced.

If the power cord seems to have no problem, try plugging another electronic device into the power outlet. If the device is powered on immediately, it means that the power outlet should not be reponsible for your LG TV that doesn’t turn on and please move to the next solution. If the device also refuses to turn it on, you need to call an electrician to troubleshoot it.

Note: Do not plug your TV and other high electricity-consuming devices into the same power strip at the same time. That’s because your LG TV may struggle to get enough power to turn when other device connected.

Fix 3. Try the Power Button on the TV

Did you power on your LG TV using your LG TV remote? Have you ever tried the power button on your LG TV to turn on the device? If haven’t, press the power button right now and your issue might disappear.

LG TVs come with a power button and the button is always on the panel of the LG logo or the rear bottom right-hand side.

Press the power button once you locate it on your LG TV and see if your LG TV will light up as expected. If this way works and your LG TV shows its main screen, there is an issue with your LG TV remote.

Fix or Repair the dysfunctional LG TV Remote

Controlling your LG TV using a remote is quite easy, but that also challenges you when the remote does not work. For example, when the batteries inside the remote have less juice or go dead, it has an inability to control LG TVs. Aside from battery issues, many other factors can stop the remote from working, and you can refer to Top 11 Fixes to LG TV Remote Not Working [Problem Solved] to figure out the reasons for your unresponsive remote.

If you get exhausted about the fixing process, there is an easy way to control your LG TV without a remote: use a remote app to control your LG TV.

Compared to a regular LG TV remote, most remote apps for LG TV are more powerful. Take the LG TV Remote app from BoostVision for example. The remote app integrates the common functions for remote controlling and introduces advanced functions, such as quick text input and navigation.

With it installed on your Android or iOS device, you can control all models of LG TVs using the device. Well, how to control your LG TV using the remote app? A few steps are required.

Step 1. Download the app and install it on your Android or iOS mobile device (phone or tablet are allowed).

Step 2.Connect the mobile device to your LG TV.

Step 3. Press the buttons on the screen of your device to control your LG TV seamlessly.

Apart from being a powerful remote control tool, the app also works as a screen mirroring and media casting tool to boost your watching experience with your LG TV.

Fix 4. Check LG TV’s Temperature

Touch on your LG TV and see if it is too hot. If your LG TV feels too hot or overheated, the LG TV won’t turn on. Overheating can cause hardware damage to the TV and in case that happens, the TV will keep in an inactive state.

If the TV’s temperature seems to be abnormal, please cool it down right now until its temperature returns to room temperature. For example, keep it away from a heat source like a fireplace or avoid it from being exposed under direct sunlight.

Performing a soft reset is another solution to the issue of LG TV not powering on. To do so, you need to:

Step 1. Unplug the LG TV from the power outlet.

Step 2. Press and hold the power button on the TV for about 20 seconds to drain residue electricity.

Step 3. Keep the TV unplugged for a further 2 minutes.

Step 4. Plug the TV back in again and try powering it on using the power button on the TV.

Does your LG TV still get stuck on a black screen? If these steps don’t work, please proceed to the next solution.

Fix 6. Unplug the LG TV Longer

A short break might be not enough for your dysfunctional LG TV. So, let the TV have a longer break, one hour or more. During the process, internal glitches and temporary memory might be removed and the LG TV issue may disappear as well.

Note: If your LG TV has a detachable power cord, you can detach it from your LG TV.

Fix 7. Check the backlight of the LG TV

If you see a green light on your LG TV but the TV shows a black screen, there might be an issue with the backlight of the TV. Backlight is the light source of TVs and is suited directly behind the LCD panel of most TVs. Therefore, when the light source goes bad, there is no light to illuminate the images that are displayed on the TV screen.

To verify whether the backlight is the culprit, you can carry out a light test like the one below.

Step 1. Turn on your LG TV using the power button on the TV in a dark room.

Step 2. Hold a flashing light very close to the TV.

Step 3. Check if you can see the image through.

If you see any images on your TV screen, it indicates that the backlight of your LG TV is damaged, and you need to ask for professional help. If you are interested in backlight repair, please refer to How to Fix Backlight on TV. If nothing is on your TV screen, the backlight might be fine, and please move to the next solution.

Fix 8. Check the Motherboard (Not for Everyone)

If all the above solutions are useless, it is probably that the TV motherboard is damaged. You can perform the following steps to verify the guess if you have rich experience with TV repair. For your TV’s safety, leave the technical task to professionals.

Step 1. Cut off the power supply for your LG TV.

Step 2. Remove the back casing from the TV.

Step 3. Find the motherboard and remove it.

Step 4. Check if the motherboard has suffered warping or burns.

Step 5. If the motherboard is severely damaged, it needs to be replaced.
