Do LED TVs Burnout?

Do LED TVs Burnout? – [Things You Need To Know!]

LED TVs are an upgrade version of LCD TVs, and the biggest change between both of them is an LED (light emitting diode).

And we all know that light produces heat, so do LED TVs burn out?

Traditionally, they are designed to not burnout. But in some cases, damage can be done.

There are a bunch of things of which you are still not aware. So, pay attention to every single word of this complete article:

Understanding of LED Technology and Burnout:

One of the main reasons why a person switches from LCD or old CRT TV to LED TV is that it doesn’t really heat up and burn out.

Here, a fact you must know is that if you keep the brightness of your LED TV at its maximum level, you can keep it there for at least 50,000 hours.

And it’s all because of the working and technology of LED TVs!

Durability and endurance are two of the main features of LED TVs, and surprisingly they are also quite significant in this case as they prevent TVs from overheating.

LED tv Technology And BurnOuts

But the real thing that plays the most vital role is ‘LED.’ You might already know that the light-emitting diode is the biggest difference between LED and LCD TVs.

In other words, other than any bulb-like light source, LED TVs use a diode that emits light and creates an image on the screen.

Moreover, LED TVs aren’t made of semiconductors that can produce excessive heat and cause burnouts.

Reasons Why LED TVs not Burnout:

You already have an overview of how and why LED TVs do not burnout, but here we’ll go to the bottom of the topic and understand each reason thoroughly:

Energy-efficient technology:

A rule of physics and nature is that energy changes its form and never dies or ends. It creates the same amount of other types of energy as its own.

Now, LED TVs utilize LED (Light Emitting Diode) technology, which is highly energy-efficient and does not produce excessive energy.

As there’s not much energy (light energy) in the beginning, quite less amount of heat energy will be formed in the end.

Electroluminescence process:

It’s a bit difficult to pronounce. Right?

So, electroluminescence is a process in which a semiconductor material emits light when an electric current passes through it.

In this process, there’s no burning of filament or something like a traditional light source (incandescent bulbs).

Long lifespan:

Its long-lasting ability also plays a vital role here. But how?

LED TVs have to work for a long and have to use less amount of electricity (electrical energy). So, (from the first reason) when there’s less energy in the beginning, there will be less energy afterward.

Advanced heat dissipation mechanisms:

There’s also a well-organized heat dissipation mechanism which can be in different forms like heat sinks, cooling fans, and proper ventilation.

Now, one of these cooling systems is currently operating in your LED TV!

Quality manufacturing:

In most cases, and especially if you have bought LED TV from a reliable manufacturer, high-quality components must be used in the production.

LED TVs also undergo hard testing to ensure durability and performance. This attention to quality reduces the likelihood of failures or malfunctions that could lead to burnout.

Surge protection:

There’s another piece of equipment used to prevent burnout: surge protection. This feature is added to safeguard against power fluctuations or voltage spikes.

Stable power supply:

LED TVs require a stable power supply to operate optimally. If you have provided it with a stable power supply, not even a spark can be detected in the TV.

With all these tiny presentations of technology, it’s almost impossible for an LED TV to overheat and then burn out.

However the technology of these LED TVs can become dangerous. The backlight or LED of the TV can sometimes fail to provide the results as required.

That’s why you must keep a few other things in mind as well!

All Symptoms of Backlight Failure:

Yes, your fully-maintained backlight can get damaged. But how will you know that your TV’s backlight is going through a failure?

Here are all the symptoms that indicate that your LED or backlight isn’t functioning well:


The most common symptom of backlight failure is here. In this situation, your TV will flicker irregularly or in a consistent pattern. You can also see it as uneven brightness across the screen.


If the brightness on your TV screen is even but is quite dim, you should be aware.

Uneven lighting:

Certain areas of the screen may exhibit inconsistent or uneven lighting, resulting in patches of brighter or darker areas.

Backlight not turning on:

If the backlight (LED) isn’t even illuminating and the screen is completely dark, the situation might be more alarming, so keep the TV off and call the technician.

Overly bright or washed-out images:

The backlight may cause the screen to become so bright that nothing appears to be clear.

Causes of Backlight Failure:

After symptoms, here are all the possible causes of backlight failure to help you out:

Power supply issues:

The power supply unit (PSU) can lead to backlight failure if not working properly. Fluctuation in light is what you may notice here.

Faulty backlight driver:

The backlight driver circuitry controls the power supply to the LEDs. In this case, you have to change the driver.


Although overheating is quite rare in LED TVs, insufficient cooling blocked ventilation, or prolonged exposure to high temperatures can still contribute to overheating.

Moisture or humidity:

Keeping your TV in a moist or highly humid room can corrode the backlight components.

Manufacturing defects:

If you are facing backlight failure a few weeks after buying a new LED TV, it might be a manufacturing defect, and it can be resolved if the TV is under warranty.


At this point, you do not just know whether LED TVs burn out or not, but you also know the reason behind it.

In this article, we’ve also introduced you to backlight (LED) failure, which can be the potential reason why you are searching “Do LED TVs Burnout?”

For the solution of backlight (LED) failure, it’s always best to go for a professional, as doing something yourself can cause more damage.
