Why is my Hisense TV overheating?

If your Hisense TV has been overheating, this post will show you likely reasons why and what you can do about it.

While there are many ways to prevent or decrease the risk of your Hisense TV overheating, ensuring the vents are clear, removing airflow obstructions, and keeping the television away from any heat sources are a few surefire ways to help the problem. Also, placing the TV in a location where plenty of airflow exists is a good idea.

Let’s dive further into the details. Keep reading to learn more about your Hisense TV overheating and how to manage this problem.

Why is my Hisense TV overheating?

In general, overheating occurs due to the one or many of the following problems:

Brightness turned up

Having the brightness turned up to the maximum setting on the television and letting it sit for hours on end is a great recipe for overheating. 

The brightness is controlled by the backlighting components, so the longer it’s running at the maximum setting, the hotter the hardware will be come.

This is also an effective way to minimize the life cycle of the television and likely must purchase one every four years.

Clogged vents

The TV has vents so that hot air can flow out of the tv and cold air can flow in. Vents can easily be clogged by dust that becomes caked on or debris that’s covering the holes. 

Without proper maintenance, as time passes, dust will build and eventually block the inbound or outbound venting holes. 

Also, placing items that cover venting on any electronic equipment is never a good idea.

Inefficient airflow

Even if you’ve dusted and cleaned the vents, if your unit is in a confined location with little-to-no airflow, then you’re still going to have a problem. 

Televisions are designed as a system to suck in cool air and blow out hot air in an endless cycle during use. If either the inbound or outbound vents cannot do their job, the system will overheat and fail.

Proximity to a heat source

Given that televisions emit a lot of heat, mostly due to the backlighting componentry, you don’t want to add to the amount of heat entering the system by placing your television in a hot area, like near a window or a heater. Adding heat to an already hot system is a recipe for disaster that can easily be avoided.

How to prevent a Hisense TV from overheating

There are many ways to prevent your Hisense TV from overheating, including:

Ensure efficient airflow

Ensuring efficient airflow to and from the television can be accomplished by placing the unit in an open area. 

In addition, one of the functions of a wall mount is to create a gap between the unit and the wall to always ensure proper airflow.

Keep the brightness at the recommended setting

This is probably the easiest solution on this list, simply keep the brightness setting at the recommended level. 

As mentioned above, having the TV set to a high brightness level will significantly increase the amount of heat being generated.

The default setting that is available when you turn on the television is where your brightness should always sit. That means you literally don’t have to do anything except enjoy your shows in the current brightness.

Move the TV to a cooler location

By moving your television away from the window and out of the sunlight, you are eliminating an unnecessary heat and humidity source. 

Place the set in the middle of the room which should be at or around room temperature and isn’t impacted by the outside weather.

Perform proper maintenance

Like with any electronic component, you should perform proper maintenance on your Hisense TV. This includes regular dusting of the vents and other areas that have gathered material and cleaning the screen with a microfiber cloth. 

To clean, you can use a hand duster for the vents or compressed air, which blows dust from the holes. When cleaning the screen with a microfiber cloth, never use harmful cleaning chemicals which can damage the components.
