How long do LG TVs last?

LG TVs last for 5 to 7 years. And this makes them some of the most reliable TVs on the market. However, how long yours manages to function efficiently relies on how you maintain it. That said, if you don’t properly take care of your LG TV, it might even stop working in under 4 years.


LG TV lifespan – 7 things you need to know


#1: LG TVs have 2 years warranty

I mentioned that LG TVs last for 5-7 years. 

And if you’re wondering… 

“But what if it fails before that?”

Then you’ll be glad to know LG will repair your TV for free if you’ve had it for less than 2 years. 

That’s because all LG TVs are under warranty for that long.

Fun fact: This is twice the warranty period of TVs from other brands.

However, remember that you can’t simply take your device to an LG service center.

And expect them to fix it right away.

That’s because…

You need to prepare 2 things before you can avail your LG TV’s warranty:

Warranty certificate

This document comes with purchasing your TV. And it lists your device’s:

  • Brand name.
  • Serial number.
  • Product name.
  • Date of purchase.
  • Period of warranty. 

Moreover, it also includes the terms & conditions of your TV’s protection plan.

That said, once you have this, the next thing you should prepare is… 

The proof of purchase of your TV

In other words, the physical or digital receipt of your device.

See, this verifies that you’re the person who bought your TV.

And it also double-checks the purchase date of your device. 

Once you have the receipt and warranty certificate of your TV…

You can then send it for service in LG service centers. 

However, note that there are restrictions to the protection coverage of LG devices. 

For example… 

#2: Disassembling your TV voids its warranty

Like other TV brands…

LG will void your warranty once unauthorized people have opened your device.  

That said, bring your TV to an official LG service center if something’s wrong with it. 

Because if you try to fix your device yourself, or with the help of local technicians…

You’ll void your TV’s 2-year free warranty. And that’s a huge waste. 

“What should I do if my LG TV is acting weird then?”

Whether your TV is in warranty or not, there are easy fixes you can try at home first.

And by that, I mean solutions that only require adjustments to your TV’s software. 

However, if no simple fixes solve your TV’s problem…

Bring it to an LG service center if it’s still under warranty.

But if it’s no longer under its protection plan…

You can open it up yourself or bring it to technicians near you. 

#3: Install your TV properly to make it last

Where you place your TV also affects its lifespan. 

That’s because installing your TV incorrectly can make it:

  • Overheat.
  • Accumulate more dust. 
  • Prone to physical damage.

With that said, if you want to make your LG TV last for 7 years or longer, you should…

Position your TV correctly (2 tips)

Tip 1: Make sure that it’s well-ventilated

TVs don’t do well in extreme temperatures.

So if yours is placed in a room that gets extremely hot (over 90°F) at noon…

It won’t last up to 7 years with you. 

That said, you should place your TV in open and well-ventilated areas.

For example, avoid placing it near windows or your kitchen where smoke can come from. 

Instead, place it in the middle of your living room. 

And cover your windows with curtains when it gets too hot. 

Tip 2: Mount your TV

As you know, mounting your TV means keeping it away from the floor.

And that means it’ll have lower chances of accidentally being tipped over. 

With that said, if you mount your TV, there’s a bigger chance that it’ll last longer with you.

However, ensure that you’re not covering any of its fans when mounting your device.

Because doing so will cause it to overheat.

#4: Dust can kill your TV slowly

A speck of dust seems harmless.

But once they pile on your TV, that’s a different story.

It’s because dust buildup can cause your device to overheat.

And as mentioned earlier, LG TVs don’t tolerate extreme temperatures well. 

Moreover, if your LG device is covered with debris…

It can start to have sensor problems. 

Or worse, your TV might even stop turning ON once the dust reaches its motherboard. 

That’s why at least once a week, I highly recommend that you… 

Clean your LG TV’s screen:

  1. Turn OFF your device.
  2. Unplug it from its power source.
  3. Wait for 10 minutes so your TV can cool down.
  4. Grab a dry microfiber cloth.
  5. Use it to wipe your device’s screen gently.

After cleaning your TV screen, you should also…

Clean your LG TV’s ports:

Step 1: Grab a compressed can or an air duster

Warning: Don’t shake your air-compressed can before doing this process. And don’t stick its nozzle inside the ports of your TV. That’s because too much air pressure can damage the pins of the ports. 

Step 2: Position the can’s nozzle an inch away from your TV’s port

Ensure that it’s pointing to the slot in an angular manner. 

This way, the air will push the dust from the ports outside your TV. 

And it won’t push them further inside. 

Step 3: Spray the port in short intervals

Lightly spray every second or so. 

And rotate the nozzle so that you’re hitting different sections of the port in every spray.

After doing so… 

Step 4: Wipe the dust from your TV

Once you’ve pushed out the debris from the ports…

Use a clean and dry cloth to wipe them off from the TV. 

Step 5: Repeat the process for all your TV ports

And that includes:

  • USB.
  • HDMI.
  • Ethernet.
  • Component. 

Warning: Never use a wet towel or soap to clean your TV. That’s because even a drop of liquid can damage the internal components of your device. 

#5: Power surges are your TV’s enemy 

If you’re not familiar with power surges…

They’re a sudden increase in the electricity power of your house. 

See, in the US, the ideal home voltage is 120v. But it’s acceptable for your electricity to be within 114v to 126v. 

That said, your wall outlets need to remain in this voltage range.

Because that’s how much electricity appliances like LG TVs are built to handle.

Unfortunately though, during power surges…

The voltage of your outlets can exceed 169v. And this can cause stress in the electrical current of your device. Thus, causing it to heat up and damage your TV’s circuit boards. 

As a result, your device will be gone far earlier than expected. 

And you’ll spend more money to replace your TV.

“Is there a way to avoid this?”

Yes, there is.

See, while you can’t stop power surges from happening…

You can protect your appliances, including your LG TV, from it. 

And that’s by using a power surge protector for your TV. 

“What’s that?”

To know how surge protectors work, watch this short video:

As you can see, it might look like a regular extension.

But it has mechanisms that prevent higher voltage from traveling to its outlet. 

That said, for just 20 bucks…

You can save your LG TV, which costs hundreds or even thousands of dollars. 

How cool is that? 

#6: Your TV picture settings affect its lifespan

LG TVs have different picture modes, including:

  • Vivid.
  • Cinema.
  • Standard. 

And all of them serve a different purpose.

For example, Vivid increases your TV’s backlight, color, and contrast.

That said, for many, this mode makes their screen display stand out. 

So they use this setting for their LG device.

However, tell you what… 

Using picture modes with higher brightness and contrast can lower your device’s life. 

That’s because LG TVs’ estimated lifespan assumes that…

You’ll use your TV in Standard mode during those years.

That said, if you use Vivid with higher brightness, instead… 

Your TV might not last for 7 years. 

That’s because it has to use its processor more to display brighter images on your screen.

Pro tip: If you want your TV to last long, keep it at Standard mode most of the time. 

“How do I change my picture settings again?”

I got you. Here’s how you can…

Revert your LG TV’s picture mode to Standard:

  1. Turn ON your TV.
  2. Tap the Smart/Home button on your remote.
  3. Head to Settings > Picture.
  4. From the list, select Picture Mode.
  5. Click Standard.

#7: LG Smart TVs can be hacked

It’s not just your phone or computer. Because someone can also hack your LG Smart TV.

And when this happens…

You bet it. Your device won’t last for as long as you expected. 

However, fret not. I’ll give you… 

2 tested tips to protect your LG TV from hackers:

Tip 1: Update your TV
Update Your TV

Let’s start with the easiest yet most effective tip: updating your device.

See, updates ensure that your TV is locked and secured. So that hackers can’t access your data. 

That said, it’s crucial to…

Regularly update your LG TV:

  1. Turn ON your device. 
  2. Head to its Settings > All Settings.
  3. Tap Support > Check for Updates.
  4. Click Download and Install.
  5. After the download, turn OFF your TV.
  6. Wait for 10 seconds.
  7. Turn it ON again.

Tip 2: Stick to official LG apps

Downloading 3rd party apps on LG TVs can be fun.

But if you’re unsure about the application you’re adding to your device…

It’s best to avoid it.

That’s because unofficial apps haven’t been checked by LG yet. 

So they can be unsafe or pose security risks to your device. 

That said, stick to the official apps you can download on your LG TV. 

How do I know if my LG TV needs a replacement?

You’d know if your LG TV needs a replacement if it:

  • Doesn’t stop flickering. 
  • Has severe physical damage.
  • Is too slow during regular use. 
  • Has dead pixels or screen display problems. 

That’s because all of these issues cost a lot to troubleshoot. 

So you’ll most likely get more value for your money if you just buy a new TV.
