How Long Do LG Smart TVs Last? (Plus How to Extend it’s Lifespan)

It’s quite common for this question to arise when considering purchasing a new LG Smart TV or shortly after making the purchase and wondering about its lifespan.

Because it really matters!

You are spending thousands of dollars, but if you can’t use it for 4-10 years, it’s a total waste of money.

But will LG TVs fulfill your hopes?

Well, this guide will break down everything about how long LG Smart TV last and what you can do to increase its lifespan.

Typical Lifespan Range for LG Smart TVs

Generally, an LG TV should last between 5 to 7 years or more with proper care.

It totally depends on the type of LG TV you have.

If you have an LG LED TV, it has a lifespan of 40,000 to 60,000 hours or 4.5 to 6.8 years; if you aren’t watching TV for 24 hours a day, it is considered a pretty good lifespan.

But, if you have an LG OLED TV, it has a much longer lifespan of 100,000 hours or 12+ years before it falls to 50% brightness.

Of course, these are just averages and your actual TV lifespan may vary depending on usage, maintenance, and other factors.

Manufacturer isn’t solely liable for a long lifespan!

When you purchase a TV, a range of responsibilities come with it that can determine whether your TV will last longer or become damaged quickly!

Here are some factors that might affect your newly purchased LG TV and how you can overcome them!

1. Usage Patterns

The way you use your TV can actually affect how long it lasts.

When you use your TV a lot every day, like watching shows, playing video games, or watching funny cat videos, it’s like your TV is working extra hard.

Just like when you play your favorite video game for hours, you might feel tired afterward.

The same happens to the TV’s “inside parts” when it works for a long time.

On the other hand, if you use your TV only sometimes or for shorter periods, it gets some rest, just like when you take a break from playing.

Rest is essential for TVs too!

Now, here comes the fun part—the type of things you do on your TV also matters.

Let’s say, your TV is a superhero—it can handle a lot of tasks, but some might be more challenging for it than others.

For example, if you use your TV mainly for watching funny videos or your favorite TV shows with regular picture quality, it’s like your superhero TV is doing light exercises.

It’s easier for it to handle that, and it stays happy and healthy!

But, if you love to play action-packed video games or watch super-duper clear movies with lots of cool special effects, it’s like your TV is lifting heavy weights or running a marathon.

Those activities put more stress on the TV’s “muscles” inside, and it might get a little tired over time.

So, try not to use it for too long every day, and give it some rest from time to time. And when you use it, maybe watch some regular TV shows or funny videos once in a while, so your TV doesn’t have to be a superhero all the time.

2. Maintenance and Care

Maintenance comes right after the usage pattern!

Proper care is essential for enjoying your TV for an extended period.

It’s not just about cleaning the screen daily; ensuring proper ventilation and keeping the software up-to-date are equally important.

Anyway, here is what you need to do:

  • Ensure that your TV is placed in a well-ventilated area with sufficient airflow.
  • Regularly clean the screen and the TV’s external surfaces using a soft, lint-free cloth.
  • Gently dust the vents, ports, and the back of the TV using a soft brush or a microfiber cloth.
  • Invest in a surge protector to protect your TV from power fluctuations and electrical surges.
  • Handle your TV with care and avoid accidentally bumping or dropping it.

And most importantly, stay up to date with the latest firmware updates provided by LG.


Q: Does the size of the LG smart TV affect its lifespan?

Generally, the size of the TV doesn’t directly impact its lifespan.

However, larger TVs may generate more heat, potentially affecting internal components if not properly ventilated.

If your’s is very large like 55 or 65″, ensure proper airflow and avoid overheating to maximize the TV’s lifespan.

Q: Is there a difference in lifespan between OLED and LED LG smart TVs?

LED TVs generally have a shorter lifespan compared to OLED TVs, typically around 4.5 to 6.8 years. OLED TVs, on the other hand, can last longer, with an average lifespan of 7 to 10 years.

Q: Can I still use an LG smart TV after its lifespan ends?

Yes, you can continue to use an LG smart TV after its estimated lifespan.

However, as the TV ages, you may experience performance issues, reduced picture quality, and compatibility problems with newer technologies and streaming services.

Q: Do LG smart TVs become obsolete quickly?

LG smart TVs are designed to stay relevant for several years.

However, as technology advances, newer models may offer improved features and compatibility with emerging standards.

While your TV may not become obsolete overnight, keeping up with technological advancements may require an eventual upgrade to access the latest features and content.
