Samsung TV Flickering – How to Fix It?

If your Samsung TV is flickering, you need to follow simple steps. First, unplug your TV from power and wait for 60 seconds. After that, press and hold the power button for additional 30 seconds. After those two steps, plug your TV back into power, and it should work again.

1. Unplug a Television from the Wall Socket

Even if you already tried to unplug your TV before, make sure you are following the exact procedure. Without proper steps, this easiest step do not have to work and your Samsung TV won’t turn on.

Make sure you identified the correct cable which is coming from your TV. With TV there are usually many other devices plugged into the same socket or power cord and you need to make sure you are disconnecting the correct cable.

Once TV is disconnected wait at least 60 seconds. In the meantime, you can search for the power button. Once 60 seconds is up you can press and hold the power button for additional 30 seconds.

This procedure will ensure that all residual energy that remain in your TV is gone and all parts of the TV were properly turned off.

Many people do not realize that even when the TV seems to be off, some parts are always powered while the device is plugged into the socket.

Once you completed both steps you can plug in your TV back to socket and it should work again!

If you belong to a small group of people for which this procedure did not resolve the issue completely, then check the other fixes below.

2. Turn OFF ECO Features (Power Saving Mode)

In rare cases where the power reset of your Samsung TV did not help, you should try turning OFF all ECO features. It is known those features do not save a lot of power; on the other hand, they can cause additional issues, including screen flickering.

Power Saving Mode usually uses a light sensor on your TV to determine the ambient light situation, and based on that, it will dim your TV screen as much as possible. 

Changing screen brightness up and down too frequently can result in flickering or other anomalies.

Turning off this rather useless feature on your TV is easy; follow those steps for newer models:

  • Press the Home button on your remote control
  • Go to Settings
  • Select General
  • Select Eco Solution
  • Select Energy Saving Mode (on some models, it is called Power Saving Mode)
  • Press Enter
  • Select OFF from the drop-down menu and confirm

Follow those steps for older models:

  • Press the Home button on your remote control
  • Go to Settings
  • Select General
  • Select Eco Solution
  • Turn off Ambient Light Detection

3. Reset Picture Settings 

If turning off ECO features has not resolved your issue yet, you can reset all settings that control your picture to factory defaults.

To reset picture settings on your Samsung TV, follow those steps:

  • Press the Home button on your remote control
  • Go to Settings
  • Select Picture
  • Select Expert Settings
  • Select Reset Picture
  • Confirm with Yes

4. Update Samsung TV Operating System

It is not secret that modern Smart TVs are small computers. It means they are running on various operating systems. Those systems are very complicated and can require regular updates to fix different kinds of issues. 

Before starting with this tip, you must ensure your Samsung TV is connected to the internet with a LAN network cable or over Wi-Fi.

You can check if you are connected to the internet by browsing Youtube videos on your TV. If Youtube is working, you have the internet on your TV.

Follow the steps below to update the software on your Samsung TV:

  • Press Menu on the remote control
  • Go To Settings
  • Select Support
  • Select Software Update
  • Select Update Now
  • Wait until TV finishes the automatic update process

It is perfectly fine if this process takes a couple of minutes. Be patient and leave the TV without any interaction until it informs you about a successful finish.

Thanks to those steps, your TV will go to default settings, and your TV will be basically in the same state as a brand new TV.

For older TV models, factory reset steps can be slightly different.

6. How to Factory Reset Samsung TV without Remote Control

Many do not know that, but you can reset your Samsung TV to factory default settings without the original remote control unit.

The first thing you need to do here is to find a power button and other control buttons directly on your Samsung TV. The place will vary based on your model and manufacturing year. 

Once you have located your control buttons, power up your TV and follow those steps:

  • Press menu button
  • Go to Settings
  • Go to General
  • Go to Reset
  • Enter your security PIN (the default PIN on every Samsung TV is “0000”)
  • Your TV will automatically reboot
  • Follow the initial setup wizard

If you can not find control buttons or if you face other issues, try the following tips.

Look around the house. You can have the universal remote control unit to control your Samsung TV as well as other devices.

If you have Samsung Smart TV, you can control your television with the app installed on your Smartphone. Go to the Play store on Android devices or the Apple store on your iPhone and install the Samsung SmartThings app.

If you have a USB Keyboard in your house (your desktop PC usually has one), plug it into your Samsung TV, and you can control it with any USB keyboard.

7. Check for Broken Cables and Loose Connections

If changing settings on your Samsung TV does not help, check for issues outside of the TV as well. 

Wrong cables or loose connections can also cause screen flickering. 

Right now most used data signal cable is HDMI.

Check back of your TV and look for connectors named HDMI Input (or just HDMI IN).

If you have more than one cable plugged into the HDMI IN connector, check the right one. 

The picture should disappear once you disconnect the right cable.

The easiest thing to do here is to replace your HDMI cable with another one. Do that first if you have an additional HDMI cable lying around.

Usually, an HDMI cable is used to connect the desktop PC and computer screen. You can use this HDMI cable to troubleshoot your TV.

If you have just one HDMI cable in your house, make sure you follow those steps:

  • Check visually if the cable is in good shape
  • Unplug and plug in both sides of the cable

HDMI cables are cheap; if you are not sure your cable is 100% fine, then it is a good idea to buy a new one anyway.

8. Change the Input Connector on Your TV

All modern Samsung TVs have multiple input connectors available

Unfortunately, some of those connectors can be mechanically worn, and as a result, it can cause various issues with the picture, including flickering.

The most used connector at this time is HDMI. Look for input connectors named HDMI 1, HDMI 2, HDMI 3, and so on.

Unplug the cable from one of those and plug it back into another one, then check if that improved your TV picture quality.

9. Try Different Ambient Light

Usually, people watch TV in the evenings with other lights turned on around the TV.

If nothing else helps, you can try to use a different light source in your TV room if possible.

Consider replacing your light bulbs if you do not have another light source like lamps or LED strips available in your TV room.

You do not have to buy a new one immediately; try light bulbs from a different room. 

If you watch TV during the day, try to darken the room with curtains.

10. Faulty Electronics

In rare cases when all other tips above did not help and flickering on your screen is too strong to be caused by ambient light, you need to consider that your TV is broken and needs to be fixed by an electrical engineer.

Unfortunately, there is no easy way to determine this without opening your TV. 

It is not recommended to do that if you do not have an electrical background and you are not a certified specialist.

If you need to replace electronics on your TV, you can find hardware repair stores in your area.

If you have a new TV, check if your warranty is still valid. Using your warranty is the best way to get help if your TV is faulty.

To Sum Up …

Samsung TVs can suffer from screen flickering sooner or later. 

In most cases, you can solve those issues quickly. However, in rare cases, you will need to use your warranty or search for a hardware shop in your area to get professional help.
