No matter what brand of TV you have – LG, Sharp, Apple, TCL, Sony – flickering or blinking TVs can all be fixed with the same troubleshooting steps.

On TV LCD screens, flickering can even be caused by loose connection ribbons and wiring. No matter what input you are using with the TV, this type of flickering is going to appear no matter what you are doing.


Turn the TV Off and On to Fix the Flickering or Blinking TV Issue.

In order to fix a flickering TV screen, you should always turn the device off and on again as soon as possible.

If you do so, you will reset your TV, which could stop the screen from flickering in the future. If you want to readjust it, you’ll want to leave it off for a few minutes before you turn it back on.

In the event that turning the TV on and off only works as a temporary solution, you will need to move on to the other methods listed below.


Unplug the TV from the wall.

The power cord from the wall outlet should be unplugged if turning the TV off and on did not help.

It may be possible to remove flickering from the TV by doing so, which forces the TV to reset. Plugging back in the power cable will require at least five minutes of waiting.


It is important to inspect your cables on a regular basis.

Your TV will need to be checked to ensure that there are no damaged cables connected to it.

It would be wise to look for loose connections, bent wires, or damaged cords when you are checking. You will be able to tell which cables are broken if you notice the flickering only happens when your TV is connected to a certain input.

If your TV only flickers when you are playing a video game, you should check all the cords attached to the console. There is a tendency for HDMI cords to break easily – you may need to replace them.

You should check the wires attached to the cable box instead if the flickering occurs only when you’re using cable TV.

It is lucky, however, that these types of wires aren’t as expensive to replace as they used to be.


Flickering and blinking TV issues can be fixed by checking the video source.

It is possible that you will experience some flickering depending on the video source.

You get this when your TV gets corrupted frames from the broadcast, whether you’re streaming or recording.

There’s no way to correct the video source, but you can try rebooting your TV or resetting your router if you’re streaming.


Lighting levels should be considered in the room.

In fact, TV screens are always flickering because they are always on. However, in any case, it will be so fast that you won’t be able to tell what’s going on normally.

In certain lighting conditions, these refresh rates are more noticeable, which can make the TV appear as if it is flickering if the lighting conditions are extreme. The room can be brightened or darkened to fix the problem.

In addition, you may be able to fix this problem by adjusting the brightness settings on your TV.

The process may take some time, but you will notice the results as soon as you begin to experiment.


Consider internal hardware problems and fix them to fix TV flickering and blinking.

Flickering issues on the screen may even come from the inside of the TV itself.

If you can’t figure out what’s causing the flickering, then an electrical component is probably worn out (such as the ribbon, for instance).

If you think this is the problem, you should try all of the other troubleshooting options first.

In most cases, you won’t be able to fix these types of problems on your own (unless you are a qualified professional). If your TV is not working properly then you should take it in for repair or consider replacing it in the near future. In some cases, if the TV is a new model, you may still be able to get a warranty for it.


Inspection of the Wi-Fi router is an extremely significant part of the process.

What kind of smart TV are you using? It is also possible that flickering screens are caused by a bad connection to your router.

You may be able to reset your router or you may be able to move it closer to the television. However, you do not want to place it too close to the wall.

There is a possibility that routers emit signals that can cause problems with older TVs. Keeping the router far away from an older TV that doesn’t need an internet connection is a good idea.


Viewing TV from a new seat.

It’s possible you’re not viewing your plasma TV at the best angle if you have one.

A flickering effect can only be seen at certain distances and angles from the TV screen. If you have a TV set up that you don’t like, you may want to rearrange it a bit or simply move to another chair.


It is time to update smart TVs.

You will probably need to update your smart TV from time to time if you have one.

A lack of software updates may cause a number of different connection issues as well as poor refresh rates. Most smart TVs have settings, support, and software tabs where you can find updates.

When you click the “update software” button, you will be prompted to wait for the update to be installed. On most smart TVs, this should be able to alleviate the problem of TV screen flickering.


Make sure that Energy Efficiency is turned off.

Last but not least, the TV screen might be flickering because of the energy efficiency setting.

Try disabling the setting on the TV and using it as usual to test if this is the case. It is likely that the TV wasn’t drawing enough power to run correctly if you don’t see any flickering anymore.



There are a number of different reasons why your TV might be flickering for a variety of reasons. In order to get rid of the problem, you must determine the cause. The good news is that this isn’t a difficult issue to fix, and these troubleshooting methods should help.

  • Activate the TV by turning it on and off
  • For five minutes, unplug the TV
  • Hardware and cables should be checked
  • The source of the video should be checked
  • Take into account the lighting in the room
