This is Why Your Hisense TV is Overheating!

Hisense Tv is known for its high quality and budget-friendly offer. Hisense TV can develop problems like overheating, flickering, and sound. 

Of all these, overheating is the most dangerous. It can permanently damage the TV, but you need not be afraid because there are solutions.

Hisense TV can overheat when the vents are dusty, when there is less or no airflow, and when the TV is near a heat source. But do not worry; there are several troubleshooting processes to fix overheating. However, if the problem persists after you have completed all the processes, it would be nice to contact a professional.

In this article, you will find detailed information on all the causes of overheating and flickering of Hisense TV. 

You will also get several solutions you can try without hiring a professional.

What Makes My Hisense TV Overheat? 

Why is My Hisense TV Overheating

Harsh conditions, which might be from external factors, can make the Hisense TV overheat. 

External factors like the surrounding environment and heat, and internal factors like the TV cooling system and hot backlight components.

#1. External Factors 

External factors that make a Hisense TV overheat are dust, insufficient airflow, and heat sources.

Here’s a detailed explanation of how these factors cause your Hisense Tv to overheat.

#1. Dust 

Hisense TVs, like all other TVs, are designed with a vent to regulate the heat in the TV by giving out hot air and receiving cool air from the environment. 

If the air from the environment comes with dust, the dust can clog and reduce the efficiency of the TV and make it overheat.

#2. Heat sources

Heat sources such as sunlight, fireplaces, heaters, or other electrical appliances can affect the air in the environment. If the air in the environment is hot, the TV will probably overheat.

#3. Insufficient Air Flow 

The Hisense TV coolant system makes use of cool air to work efficiently. 

Therefore, insufficient airflow can cause the TV to overheat because the cooling system will stop working at its best performance.

#2. Internal Factors

Internal factors that make the Hisense TV overheat are hot blacklight components and clogged vents.

#1. Hot Blacklight Component 

Blacklight component controls the brightness of the TV and, when overworked, can result in the components becoming hot and therefore overheating the TV. 

This component can be overworked when the brightness of the TV is on to its maximum.

#2. Clogged Vent

For an effective cooling system, the vent needs to open for the free flow of air. 

When this vent clogs with dust or dirt, it reduces the inflow of cool air and outflow of hot air, which makes the TV overheat. 

Can Overheating Cause My TV to Go Off?

Have you noticed that your TV suddenly shuts down? Overheating can cause a TV to shut down or run less properly.

LCD TVs can be damaged permanently by overheating, and one of the ways to know that the TV is overheating is when the TV shuts down.

Because of this, you must watch out for factors that make the TV overheat to keep the life of the TV.

Because of the heat emitted from a working TV, a cooling system is in place. 

The cooling system regulates the temperature of the TV. One of the system’s features is a small ventilation vent allowing airflow. 

This vent can be obstructed by dust and cause the TV to overheat. So the vents must be kept clean and placed in a dust-free environment.

Airflow is very important to cool the system. Position the tv at a spot that encourages the free flow of air.

Try to avoid tightly enclosed spaces. If possible, place a fan close to the TV.

External heat can also increase the temperature of the air, which will flow inside the TV through the vent. 

Therefore, lowering the temperature inside the TV will cause overheating. 

This external heat can come from direct sunlight, the refrigerator, a heater, and other heat-generating electronic appliances.

Why Does a Hisense TV Keep Flickering?

Damaged cables, outdated TV software, weak internet connection, and electrical Interference can cause the Flickering of a Hisense TV.

Hisense tv can flicker because of damaged or loose cables or electrical Interference

Sometimes it results from completely wearing out of the outer layer of the cables, exposing its wire.

Below are some causes of the continuous flickering of your Hisense Tv;

#1. Damaged Cables and Parts

TV cables are mostly prone to wear and tear, which can cause the tv to flicker.

So it is important to check the cables and replace them if they are faulty when a TV is flickering.

#2. Outdated TV Software

Just like smartphones and Laptops, Smart TVs software can also be outdated. Outdated software can keep or make a TV flicker.

#3. Weak Internet Connection

If the TV keeps flickering while streaming, it might result from a weak internet connection.

Checking and rectifying the internet connection will boost the internet speed and stop flickering.

#4. Electrical Interference

Buzzing noises and flickering of the TV can result from electromagnetic and electrical Interference. Turning off the TV for some time will resolve Flickering.

In the table below are types of flickering, their causes, and fixes.

Types of Flickering Causes Solutions 
Flickering on and off A damaged cable or a faulty power outlet.Plug the TV into another outlet. Replace worn-out or damaged cables with new pairs of cables.
Flickering horizontal lines Damaged cables Broken LCDRun a self-diagnostic picture test to determine whether the display is corrupt. 
Flickering of vertical lines Worn out cablesPower Turn the TV off and unplug the cord. After 2 minutes, plug it back and turn on the TV. 
Screen black flickering HDMI Unplug and replug the power cord after 15 seconds.

Note that there are two types of reset: hard and soft reset.

Steps to soft reset

  • Turn off the TV. 
  • Disconnect the main power supply by unplugging it.
  • Wait for two minutes.
  • Plug the TV back.
  • Turn it on.

Steps to hard reset 

  • Press and hold the exit dolphin for 15 seconds.
  • Press ok, and the factory service menu pops up on the screen.
  • Turn the TV off.
  • Wait for at least 20 seconds.
  • Turn the TV on.

How Can You Stop a Hisense TV From Overheating?

There are several factors responsible for Hisense TV overheating, which range from internal factors to extended factors. 

These factors need to be identified promptly to stop the TV from overheating.

External factors that cause overheating are:

  • Insufficient airflow;
  • Dust
  • Heat sources

Internal factors are;

  • Hot backlight component
  • Clogged vent

Let’s discuss the remedy for these factors.

Factors Remedy 
Insufficient airflow Use a cooling fan or an AC to enhance airflow and maximize performance.
DustWhen positioning the TV, place it in a dust-free environment to prevent the inflow of dust from the vents.
Heat sources Place the TV should far from any heat source to reduce this problem. Also, ensure to place a fan directly towards it.
Hot backlight component To maintain a cool backlight component temperature, you shouldn’t turn the TV’s brightness on for a long time.
Clogged vent Clean the vent regularly.


Dust, insufficient airflow, hot backlight component, and clogged dust will cause overheating in a Hisense TV. 

As for flickering, its primary causes are worn-out cables, faulty power outlets, outdated tv software, and internet connection. 

While there are many solutions to overheating and flickering of TV screens, if a problem persists, please do well to call an expert to check and repair it.
