Fix Hisense TV Overheating Issues in Seconds!

Quick Fix

The primary cause of Hisense TV overheating is the blockage of its vents because of dust. If you don’t clean your TV ventilation vents frequently, the dust will build up inside its vents over time and will cause your Hisense TV to overheat. You can easily prevent it from overheating by cleaning and dusting its vents at least once a month!

I’ve also encountered overheating problems with Hisense TVs. Upon investigating, I discovered the reasons behind this issue and ways to fix it.

This article will explore the reasons behind the overheating of Hisense TVs, along with solutions and tips for prevention.

Causes of Hisense TV Overheating

  1. Blocked vents: TV ventilation vents allow heat to escape from the internal components. Airflow is reduced when walls, objects, dust, and garbage cover these vents. This blockage traps heat inside the TV, causing the internal components to overheat.
  2. TV placement in direct sunlight: TVs absorb much heat from direct sunlight. This external heat source adds to the TV’s natural heat.
  3. Extreme brightness: Using the TV’s maximum brightness for an extended period can increase the temperature of its internal components. Overheating may occur if you watch your TV at full brightness for an extended period.
  4. Apps running in the background: Smart TVs that can run apps might overheat if too many are running or some are resource-intensive.

How to Fix Hisense TV Overheating Issues?

Since you know the causes, let me guide you step by step details to fix the issue!

Step 1: Turn Off Hisense TV for Cooling

Turn Off Hisense TV for Cooling

When you discover your TV is overheating, immediately turn it OFF to prevent any severe damage.

Note: Keep your TV OFF for 10 minutes before proceeding to step 2.

Step 2: Try these Solutions

Once your TV is fully cooled down, proceed with these troubleshoots individually.

1. Ensure Proper Ventilation

To prevent overheating and extend the lifespan of your Hisense TV, ensure adequate ventilation by following these guidelines:

  • Position your TV in an open area: Avoid placing your TV in enclosed spaces or against walls, especially if the vents are located on the back. This will allow for optimal airflow and prevent heat buildup.
  • Maintain a 4-inch gap from the wall: Maintain at least 4 inches of space between the back of your TV and the wall. This gap will facilitate sufficient airflow and prevent overheating.
  • Avoid placing near heat sources: Keep your TV away from heat sources like radiators, fireplaces, or direct sunlight. Excessive heat can contribute to overheating issues.
  • Keep vents unobstructed: Do not block the vents on the back or sides of your TV with objects or furniture. These vents allow heat to escape, and obstructing them can trap heat and lead to overheating.

Following these simple ventilation guidelines can help your Hisense TV operate efficiently and prevent overheating issues, extending its lifespan and ensuring optimal performance.

2. Remove Dust from Vents

Cleaning Hisense TV vents

Dust and debris can accumulate in the vents and obstruct airflow, leading to overheating.

Use a soft brush or compressed air to remove dust and debris from the vents gently.

3. Check the Power Supply and Cables

Check the Power Supply and Cables

Inspect the power supply and cables for damage or wear. Faulty wires or power supplies can lead to overheating. If you suspect that the cable is defective, you should replace it.

Step 3: Turn On Hisense TV After Cooling

Now power your Hisense TV and follow these troubleshooting methods.

1. Lower TV Brightness to Reduce Heat

Lowering the brightness and backlight settings on your TV can help reduce the heat generated by the screen.

Doing this can also extend the lifespan of your Hisense TV.

Pro Tip

Some users have reported that their Hisense Roku TV overheats when they consume 4k content via apps like Hulu/Disney, Paramount+ HBO Max, etc. This is because these apps can strain the TV’s processor, which can generate more heat.

2. Manually Check for Hisense TV Firmware Updates

Regularly check for and install firmware updates for your Hisense TV. Sometimes, manufacturers release updates to improve the TV’s performance and address overheating issues.

Updating Hisense TV VIDAA OS

To check for updates manually on your Hisense TV, follow these steps:

  1. Press the Quick Menu button on your remote control.
  1. Navigate to the Settings menu and select it.
  1. Scroll down to the Support option and select it.
  1. Select System Update from the Support menu.
  1. Choose Check Firmware Upgrade and press OK.
  1. Your TV will check for available updates. If an update is found, follow the on-screen instructions to install it.

Updating Hisense Roku TV

To manually check for firmware updates on your Hisense Roku TV, follow these steps:

  1. Press the Home button on your remote control.
  1. Scroll down to the Settings option and select it.
  1. Scroll down to the System option and select it.
  1. Scroll down to System update and select it.
  1. Select Check now.
  2. The system will check if there are any updates available.
  1. If an update is available, follow the on-screen instructions to install it. Otherwise, you can exit the menu.

3. Enable Energy Saving Mode

Many modern TVs have an “Eco” or “Energy Saving” mode that reduces power consumption and heat generation. Enabling this mode can help reduce excessive heat.

Many modern TVs have an “Eco” or “Energy Saving” mode that reduces power consumption and heat generation. Enabling this mode can help reduce excessive heat.

Note: Energy saving mode can often be found in the local dimming options or the picture mode settings of your Hisense TV.

4. Close Unused Background Apps

If your TV has smart features and runs apps in the background, force quit any unused apps to reduce background app usage.

Running apps like Netflix, YouTube, and Spotify simultaneously can strain the TV’s processor and generate more heat.

Note

Hisense’s Android TV implementation is notorious for its poor memory management. To close unused background apps, you have to manually go into app settings and force close each one.

This is a tedious process, and it’s a shame that Hisense hasn’t done a better job of optimizing Android for their TVs.

One workaround: You can enable developer options on your Hisense TV by clicking on the build number 10 times.

In developer options, you can limit background processes to 1 or 2. However, even with this workaround.

5. Utilize a Fan to Enhance Ventilation

In addition to the previous ventilation guidelines, employing a fan to blow cool air onto the back of your Hisense TV can significantly enhance airflow and prevent overheating issues.

This approach is particularly beneficial in warmer environments or when using your TV for extended periods.

Utilize a Fan to Enhance Ventilation

Choosing and Positioning the Fan:

  • When selecting a fan, choose one with a high CFM (Cubic Feet per Minute) rating.
  • This ensures the fan generates sufficient airflow to cool your TV effectively.
  • Position the fan approximately 12 inches from the TV, ensuring it directly blows onto the ventilation vents.

Factory Reset (Last Resort)

If you have tried all the other solutions in this article and your Hisense TV is still overheating, you may need to perform a factory reset.

Note: This will erase all your settings and data, so it should only be used as a last resort.

Recommended Hisense TV Operating Temperature

The operating temperature of a TV refers to the range of temperatures within which the TV can safely operate without experiencing any damage or performance issues.

The TV manufacturer specifies this range, and can vary depending on the specific model. However, most TVs are designed to operate within a temperature range of 40°F to 95°F (4°C to 35°C).

Note

The operating temperature for Hisense TVs is 41°F to 95°F (5°C to 35°C). This means the TV can safely operate within this temperature range without experiencing damage or performance issues.

Please note: To confirm the recommended operating temperature for your specific Hisense TV model, please refer to your TV’s manual.

However, it is important to note that the TV should not be exposed to freezing temperatures while in use, as this could damage the LCD.
