LG TV Won’t Turn On? (Try these Fixes!)

Even though they are among the most well-liked TVs available, LG TVs have a terrible problem with not turning on.

When your LG TV won’t turn on, it can drive you nuts, but there are some simple fixes you can try.

In most cases, power cycling the TV can fix the problem. To do this, simply unplug it and replug it back in. In other cases, it might be an issue with a pending software update.

In either case, there are several simple methods to try to attack this issue. Let’s quickly talk about how to fix the “LG TV won’t turn on” issue.

It is important to keep in mind that these steps work for other TV brands as well. Regardless of your TV brand, these troubleshooting tips should come in handy.

Clearly, the “turned off” part is the problem here, yet power cycling any electronic device, including LG TVs, can sometimes solve the problem.

You can power cycle your LG TV by simply unplugging the TV from the outlet in the wall for around 30 seconds, then plugging it back in.

After you plugged back in your LG TV and its power indicator confirms the power is being fed back to it, you can turn it on using the power button on the TV (not the remote).

If this works, then perhaps the problem is with the remote. Either it could use some new batteries or, in more rare instances, the remote might need to be replaced.

You can search many online marketplaces for a good deal or contact LG with the specific TV model number to play it safe. 

Remove Batteries From LG Remote

Sometimes the problem is not with the TV at all, but with the remote. There is a good chance that your LG TV won’t turn on if your remote’s batteries are dying or completely drained.

If the batteries have been recently replaced, try removing them. Hold the remote’s power button down for 15 to 30 seconds later, then replace them, and try again.

Check the Condition of Your LG TV Power Cord

If your LG TV still won’t turn on after you’ve performed a soft reset and checked the remote, it might be a hardware problem. It’s time to check your power cable.

Take a closer look at the cable. If you see any visible signs of wear, especially at the end that connects your TV, it might be to blame.

If inspecting your TV’s power cord doesn’t fix the problem, there are a few more things you can try to resolve the issue.

Change LG TV Input Source

When you try to turn on the LG TV, does the red light come on? You may need to change the input settings if that is the case.

Most TVs offer at least two HDMI or HDMI 2 input options. You may check which slot your HDMI is connected to by looking at the back of your TV. Make certain that the correct input option is selected on the TV.

There are two ways to do this:

Check LG TV’s Power Source

Consider the light indicator mentioned in the previous suggestion. Your LG TV will not turn on if it is plugged into the power source but the light indicator is off, meaning the power source is not supplying electricity to it.

So it is important to confirm that the power source is actually providing the power needed to allow the TV to function.

You can confirm that the outlet works by plugging in a smaller electronic that you can verify works in that outlet.

This can be anything small like a phone charger or a bedside lamp. If no change is detected, then you need to look into the reason for the lack of power. (Many times something caused the breaker to trip, and it just needs to be rebooted).

Check for Backlight Issues

If the power light comes on but the screen is still dark, chances are the backlight of your LG TV is broken.

The images that you see on your TV screen are illuminated by the backlight. Your TV won’t appear to switch on without it. Let’s see if we can confirm that.

Turn on the TV first. Next, take a flashlight and point it directly at the dark screen. If images appear out of nowhere, your TV’s backlight is broken. Fortunately, it can be changed!

It will cost between $100 and $150 to hire a mechanic to fix the broken backlight, including labor. The choice will then be between paying money to fix your TV and investing in a new one.

Motherboard Is Bad

The last possible reason a TV won’t turn on could be due to a broken motherboard. There are a few signs to help you pinpoint if that is the problem.

However, fully confirming that the motherboard is broken will require disassembly and a multimeter device. If you don’t feel confident handling this yourself, call a TV mechanic.

Signs of a Bad TV Motherboard:

The telltale sign of a broken motherboard is when a TV intermittently won’t turn on. Additionally, if a TV turns on but can’t be turned off, you are most likely dealing with a motherboard that needs to be replaced. 

Check the Motherboard with a Multimeter

1. Remove the back panel of the TV and set aside all screws
2. Identify the motherboard, which is usually green and on the left-hand side
   1. Confirm this by checking the manual (or online)
3. Use the multimeter to test each source of voltage
4. Detect a dead voltage source to confirm a faulty motherboard

Next, go to Settings > General > Reset. You’ll need to enter your security PIN (0000 is the default). Your TV will go through the reset process, and then you’ll see the initial setup screen.

This will restore your TV to the factory settings as if it was a brand new TV. We hope this helped fix your LG TV.

It’s important to remember that tech support will likely try to guide you through the steps already discussed above first.

Technical support from LG will provide troubleshooting steps if they determine that your LG TV is experiencing an issue.

They may also recommend that an on-site technician come out and repair your TV or that you send your TV in for repairs. There are rare instances of these situations, but they can happen.

Usually, a simple power cycle can fix it when LG TV not turning on. Other times, you may need to go through all the tips above in order until you find the fix that works for you.

Here’re all the solutions we covered to fix your LG TV power problem:

• Unplug the power and check the prongs
• Look for damaged cords
• Test the power strip/extension cord
• Check the cords behind the TV
