How to Fix a Flickering TV Screen (10 Easy Fixes!)

However infuriating, a constantly flickering or flashing TV screen may often be remedied on your own.

Make careful you turn the TV off and back on before you begin troubleshooting.

There will be no need to attempt the remainder of the instructions if this addresses the issue.

But if that simple remedy didn’t help, it’s time to start diagnosing your flickering HDTV.

Fixing a Blinking or Flickering TV

A physical problem may be at blame if turning the TV off and back on doesn’t repair your flickering screen. Before attempting to remedy the flickering, you should verify all physical components and connections, such as cables and adapters.

There are a number of reasons why LCD panels may flicker, including loose connecting ribbons and wires. There is no way to avoid this sort of flashing regardless of what input you’re utilizing with your television.

What’s going on with the wires and cables? Is the network secure? What’s going on with you? Step by step, we need to find out what went wrong and how to remedy the problem, so let’s get started with the troubleshooting.

Fortunately, flickering or blinking TVs of any manufacturer – LG, Sharp, Apple, TCL, or Sony – may be resolved using the same troubleshooting procedures.

Turn On and Off the TV

Turning off and restarting your device is the first thing you should do if your screen flickers.

The screen may no longer flicker if you restart your television.

You’ll need a few minutes to get used to it.

These additional ways are better to try if turning on and off the TV is simply a temporary fix for your problem.

Unscrew the TV’s Wall Plug

Unplugging the TV’s power cable from the wall socket may be necessary if turning it off and back on doesn’t fix the problem.

Flickering may be reduced as a result of this action.

You must wait at least five minutes before connecting in the power cord again.

Make Sure Your Cables Are Working Properly

You’ll want to check to see if any of your TV’s cables have been damaged.

Make sure there are no loose connections, twisted cables, or broken cords.

You’ll know exactly which cables are failing if the flickering occurs just while a certain input is being used.

If your TV just flickers while you’re playing a video game, for instance, you should check all of the wires connected to the console in question. HDMI wires are notoriously flimsy, so you may want to invest in a new one.

It’s best to look at the cable box’s wiring if the flickering occurs just when you use cable TV.

Fortunately, replacing these sorts of wiring isn’t as expensive as it used to be.

Look at the Video Source

It’s possible to see minor flickering depending on the source of the video.

Streaming or recording anything and the TV gets corrupted frames from the broadcast might cause this.

Unfortunately, the video source cannot be corrected. The TV may be rebooted or your network reset if you are streaming.

Consider the Light Levels in the Room

In reality, television displays are continually flickering. However, you won’t be able to know since it’s so quick.

Depending on the lighting circumstances, these refresh rates might seem to flicker on the screen. A brighter or darker room will cure it.

You may also increase the brightness of your TV to correct this issue.

A little testing is required, but the results are immediately noticeable.

Think about Internal Hardware Problems

Even the TV’s internal components may be to blame for screen flicker.

If the flickering persists and you haven’t found the source, it’s likely due to the wear and tear of an internal electrical component (like the ribbons, for instance).

Before determining that this is the issue, you should attempt all of the other troubleshooting methods.

It’s impossible for you to address these issues on your own (unless you’re a skilled expert). The best thing to do is take your television to a repair shop or consider purchasing a new one. If this is a recent television, you may still be eligible for a warranty.

Look at the Wi-Fi Router

No, I don’t have one.

It’s possible that a flickering screen is the result of a faulty network connection as well.

A reboot of the router or relocating it closer to the television may be all that’s necessary to fix the problem. As long as you don’t go too near.

Older TVs may not be able to handle the signals that routers transmit.

Keep the router away from the screen if you have a TV that does not need an internet connection.

Relocate to a Different Seat

The easiest way to see your plasma TV is to make sure you’re seated at the right angle.

You’ll only see flickering when you’re a certain distance or angle away from the screen. You could want to adjust your TV seating arrangement a little, or just get a new chair.

Smart TVs need to be updated.

Every so often, you’ll need to update your smart television.

There are a number of problems that might occur if you don’t keep your software up to date. Settings, support, and software updates should be included in most smart TV menus.

Wait for the update to finish installing after selecting “update software.” On the vast majority of smart TVs, this should alleviate screen flickering.

When Energy Efficient is turned off,

Finally, the screen flickering might be caused by the energy efficiency option.

Use the TV as usual to see whether this works or not. After a few minutes, you should see no more flickering on the screen.


If your TV is flickering, there are a number of possible causes. You’ll need to figure out what’s causing the problem before you can solve it. Fortunately, this problem isn’t difficult to fix. Troubleshooting approaches such as these should be helpful:

  • Turn the television off and back on again.
  • Take a five-minute break from the television’s power cord.
  • Make sure all the wires and hardware are in order.
  • Verify the source of the video
  • Consider the amount of light in the room.
  • Take a look at your WiFi router.
  • The TV should be updated.
  • Change the settings for energy efficiency.
