How To Fix Hisense TV Flickering Screen (STEPS)

Why does my Hisense TV screen keep flickering?

The main reason why your Hisense TV keeps flickering is because of electrical interference from nearbye devices or a damaged or loose HDMI cable. 


Possible Causes

  • Outdated TV software
  • Dust inside the ports
  • Weak internet connection
  • Electrical interference
  • Damaged HDMI cable
  • Loose HDMI cable


Damaged cables and ports

Cables are prone to wear and tear. Since they remain out of your sight, you may not have noticed any damage—the first thing to check whenever your TV flickers is the cables. You should buy a new set of cables. Also, if the cables are flawless, you should check the TV’s cable ports. Damaged ports also result in the same problem.


Outdated TV software

Smart TVs’ software needs regular updates – just like your laptop or smartphone. A TV screen’s flickering may indicate that your TV is being run on outdated software. You should update it quickly to fix the issue.


Dust inside the ports

Your TV ports may be clogged with dust. If it remains unnoticed for too long, it starts causing problems. You can try cleaning the ports with the help of a plastic dental pick or a toothpick. The other method is to use compressed air to shake dust particles and clean the ports.


Weak internet connection

If you are streaming something on the TV, the flickering might be due to a weak internet connection. Check your internet connection and see if it’s running fine. You can run a quick speed test to verify whether your internet is creating any trouble.


Electrical interference

Electromagnetic and electrical interference also causes disruptions in your TV’s performance. Flickering or buzzing noise from your TV is a result of such interference. If the problem is too severe, it is better to turn off electronic gadgets that are not needed.

How do I fix a Hisense TV screen that keeps flickering?

To fix a Hisense TV screen that keeps flickering, reboot the TV and replace the HDI cable.


Here’s each fix explained step-by-step:

Reboot The TV [Method 1]

  1. Turn off the TV.
  2. Unplug it from the main power source.
  3. Wait for 2 minutes (60 seconds).
  4. Plug the TV back.
  5. Turn it on.


The above method is referred to as “the soft reset.” There is another type of resetting, which is called “the hard reset.” You can fix this using the following.


(Note that these steps are for Hisense TV 2013 or older methods.)


  1. Press the Exit button on your remote for 15 seconds
  2. A Factory Service menu will pop up on the screen.
  3. Press the OK button
  4. Turn off the TV
  5. Wait 20 seconds
  6. Turn on the TV


For newer Hisense TV models, follow these steps:

  1. Press the Menu button on the remote
  2. Choose Support
  3. Press Enter or OK
  4. Choose Self Diagnosis
  5. Click Enter or OK
  6. Select Reset
  7. Enter your pin
  8. If you don’t have a pin, type 000, which is the default pin code.


Replace Cables [Method 2]

Replace any damaged TV cables. A damaged cable can cause the flickering on your Hisense TV screen.


Change Your Angle [Method 3]

This solution may seem a bit too straightforward. But a thing about smart TVs is that they have a better view at a particular angle. You should either readjust your TV or change your position/seat if you see that your screen is flickering. If the screen works perfectly well, you will know that the issue was the bad angle.


Check The Video Source [Method 4]

If your TV is receiving corrupted frames, its screen may flicker. There’s no fix for this cause. All you can do is reset the TV and check if the screen is still flickering. The problem will go away when the signals from the video source are recovered.


Reduce The Refresh Rate [Method 5]

  1. On your TV, open the Settings option.
  2. Go to Display Settings.
  3. Scroll through to Refresh Rate
  4. Set the rate of your choice
  5. Select Confirm


Note: Older Hisense models support the refresh rate of between 50-60 Hz. The newer models can support 90Hz. If there are 2 refresh rate options, choose both one by one to check which option works best for your TV.


What does it mean when my Hisense TV is flickering?

When your Hisense TV keeps flickering, it means the TV is picking up corrupted frames sent by the primary video source.


In this case, there isn’t much that you can do as the problem will be resolved only if the video source starts sending uncorrupted frames. While you will have to wait for the video source to get corrected, you can also try resetting the TV. For this:

  1. Turn off the TV.
  2. Wait for at least 20 seconds.
  3. Turn on the TV.


Note: Some Hisense TV models come with a reset button. You can press the button for 15 seconds and let the TV reset.


Why is my Hisense TV flickering on and off?

The reason your Hisense TV is flickering on and off is because of a damaged HDMI cable. Sometimes, the outer layer of the cables gets completely worn out, exposing the wires. And since these wires keep brushing against the TV console or the wall, they damage quickly.


To resolve thos problem, you will have to get a new pair of cables to resolve the issue. You should consider buying high-quality cables that are thick so that their outer layer doesn’t get damaged quickly. Also another cause could be the faulty power outlet. If you have any alternative power outlet nearby, you should plug the TV into it.


Why does my Hisense TV screen keep flickering lines?

The reason your Hisense TV screen is flickering with lines is because of electromagnetic interference. Devices that use the same or higher frequency as your TV interrupt the electric signals received by your TV.


As a result, your TV display gets disrupted.


To fix the issue:

  1. Switch off the nearby electronic devices.
  2. Turn on each of them one by one.
  3. See which device causes more disruption.
  4. Turn that device off.


How to fix flickering horizontal lines on a Hisense TV?

To fix flickering horizontal lines on a Hisense TV, you should run a picture test on the TV.


Horizontal lines on a Hisense TV could also be caused by damaged wires and tables or a broken LCD.


You can start the picture test by following these steps:

  1. Press Quick Menu
  2. Go to Settings
  3. Click on OK
  4. Choose Support and Press OK
  5. Scroll down to the Self Diagnose button
  6. Select Picture Test
  7. Press OK


The picture test can tell if the display is corrupted or not.
