How Long Does a Smart TV Last?

After installing and mounting a newly purchased smart TV or any other home appliance, the least of our expectations is repairing or replacing damaged parts in a short while or even replacing the whole new smart TV.

Our hope at times is to see our newly purchased smart TV last up to 15 to 20 years, but is that always the case?

No is the answer, as some don’t even last up to 5 years. In this article, let’s delve into how long a smart TV is supposed to last. Come along.

Just like any other home appliance, the lifespan of a smart TV is dependent on factors like the manufacturing and brand quality, how often it’s used, the operational duration, how often its operating system and other apps are updated, reasonable voltage (without any abnormal spikes, and several outages), and many others.

There’s no rule on the longevity of smart TVs, but average, a smart TV can last between 10 and 20 years, depending on the above-listed factors.

As some smart TVs will require repairs just after five years of usage. Other smart TVs go as long as 15 and 20 years without any repairs or parts replacement.

For a smart TV to last up to 20 years of usage, all the above-listed factors should be considered carefully and fully, without any exception.

You can fully consider all the factors except reasonable voltage, and just because of that, there’s no way your smart TV can last to your expectation. Same with the other factors if they are left out.

Factors that Affect the Longevity of Smart TVs

As stated earlier, there’s no rule on the longevity of smart TVs or any other known TV. For a TV to last long and your expectations, you should be careful about its usage.

You should consider a few factors, and that’s exactly what we will be looking at now.

Factors the Affect the Longevity of Smart TVs

The longevity of a smart TV depends on;

  • Quality (brand & manufacturing quality)
  • Reasonable voltage (outages and spikes)
  • Usage times and durations (watch time)
  • Update of operating system and apps

Quality (brand & manufacturing quality)

The manufacturer and brand of a smart TV have a great effect on its longevity. Some TV manufacturers and brands are well known for their best-quality smart TVs.

A good manufacturer and brand use quality and durable materials to make the smart TV. The design and assembly are top-notch too.

So if the materials used are of the best quality, designed, and assembled by professionals, you’re assured of a quality smart TV. And chances of quality product lasting longer if handled with care is very high.

Reasonable voltage (outages and spikes)

The United States, for instance, is not that known for power outages, but there at times quite a, several spikes in the voltage.

And as we know, these voltage spikes can cause power surges, damaging your smart TV.

 Smart TVs and many other household appliances usually have a voltage level between 110 and 270.

So when the voltage coming into the smart TV goes significantly high and drops drastically within a short period, it can harm your smart TV and most of your home appliances if they are not stabilized.

To prevent power surges from damaging your smart TV, you must use a point-of-use surge protection device. This will help safeguard and protect your smart TV from any power surge.

Aside from using a point-of-use surge protection device, you opt to unplug your smart TV when not in use.

Usage times and durations (watch time)

The number of times you turn on and watch your smart TV can affect its lifespan. Like most home appliances, televisions (not only smart TVs) have a lifespan, though it’s inaccurate.

So the more you turn your TV on, whether it’s being watched or not, you will reduce its lifespan.

It is therefore always advised to turn off your smart TV anytime it’s not in use. Televisions are not for decoration and shouldn’t be turned on when no one is there to watch or when no one is interested in what’s been shown on them.

In that case, you turn it off to save your smart TV from lifespan reduction.

Update of operating system and apps

Smart TV is well known for two things that are being able to use the internet and also install apps on them.

All smart TVs have an operating system (OS), that enables users to access and have control over some features smart TVs come with. The apps help add some extra features to the TV, making its usage flexible.

Popular smart TVs’ operating systems include Roku TV, WebOS, Android TV, Tizen OS, Google TV, Ubuntu TV, MeeGo, Rayv, Microsoft Mediaroom, and many others. LG smart TVs use WebOS, while Samsung smart TVs also use Tizen OS.

Some operating systems’ names indicate the smart TV that utilizes them, like Roku Tv, Ubuntu TV, Google TV, and Android TV.

These operating systems and installed apps need to be updated from time to time. Developers of these OS and apps release new updates when they discover some loopholes in them.

So the update tends to solve the loophole or issue they discover. Sometimes they release updates when they want to add new features to existing ones.

Therefore, for your smart TV to last as expected, you’ve got to see that both the OS and the other installed apps are updated as and when new updates are released.

To avoid checking out from time to time to see if there’s a new update to install, you can set your smart TV to auto-update.

And with this setting, anytime there’s a new update, it will automatically update itself without a user initiating an update.

How to Increase Your Smart TVs Lifespan

Now that we have come to know what can affect your smart TV’s longevity let’s glance at how to increase your smart TV’s longevity.

  • Keep your smart TV clean always

Use a surge protection device

As low as $15, you can protect your smart TV against power surges. Surge protectors are not expensive, and you can order one for yourself here.

It is safe to use surge protectors, though TVs mostly come with the instruction to plug them (TV) directly into the wall.

Using a surge protector for your smart TV wouldn’t harm your TV more than good.

You wouldn’t always get a stable voltage, so with the help of your surge protector, you’re assured of a regulated voltage going to your smart TV.

Turn off the TV when not in use.

The lifespan of a smart TV ranges from 40,000 hours to 100,000 hours. And the more the TV is in use, the more the lifespan shrinks.

And because of that, you can’t say you’re not going to watch the TV, no! So what we advise is to turn off the TV when not in use.

I have always said the TV light or display isn’t for decoration, for it to be turned on, even when not in use.

Turn the TV on when you want to watch, and turn it off when you’re done. With this simple habit, the lifespan of your smart TV can go to the expected time.

Buy quality smart TVs

Best and quality products always come with a higher cost but are always worth the cost.

We, at times, make cost comparisons about products, forgetting good and quality things always come at a cost.

When you buy a good smart TV from one of the best manufacturers, you’re assured of the longevity of your smart TV. You can use your smart TV for years without a repairman touching it.

Keep your smart TV clean always.

One of the things that are most underrated with TV is dust. Your smart TV should always be kept clean and dustless.

You should know how frequently to clean your TV depending on the rate it makes dirty.

If your home is around a dusty area, you probably have to clean your TV from time to time.

This happens when you don’t clean your TV; the dust accumulates outside it and later finds itself inside.

Excess dust on the inside of the TV cause it to overheat, which can easily damage it completely.


There’s no rule on the longevity of your smart TV. For your smart TV to last the expected time, you must ensure you buy a quality smart TV.

Buy your smart TV from brands or manufacturers whose TV has been tested and approved to be good quality and built with the best materials.

And as you’re buying a quality smart TV, do not forget to get yourself a power surge protector.

This is to help protect your TV against power surges. Another important thing to note is always to ensure your smart TV is turned off when not in use. With these few measures, you’re assured of a long-lasting smart TV.
