7 Most Common Problems with Samsung LED TVs & The Solutions

The most common problems with Samsung LED TVs are very easy to solve. The only challenge is that you have to know the right steps because we know the feeling. Don’t you just hate it when you come home looking to unwind after a hard day’s work only to find that your TV refuses to work?

That’s why you get a load of knowledge with this guide that can help you fix many issues with your Samsung LED TV.

#1: Samsung LED TV Keeps Turning Off

The modern Samsung LED TV is compatible with several different devices. Each of these devices, when authorized, can turn your television on and off independently.

However, if your device keeps turning on or off on its own regularly, then there’s a malfunction. Here’s what you can do.

Check the Power Source

  • Unplug the television and check the power cord for visible damage and cuts.
  • If there is no visible damage, re-plug the Samsung TV and update the TV’s operating system.

Update the Operating System of your Samsung LED TV

  • Using the remote, navigate to Settings and then select Support. In the new window, you’ll be able to pick the Update Now option.
  • The update can take up to 30 minutes, depending on your internet speed.
  • Make sure to keep the TV on till the updates are complete, or you’ll need to call a technician to fix the resultant problem.

Turn Off the Power on with Mobile Option

If the previous solutions don’t work, you should disable the Power on with the Mobile option.

  • Go to Settings and select General. Inside, pick Network and then Expert Settings.
  • Find the Power on with Mobile option and turn it off.

#2: Samsung LED TV Picture is Flickering

A flickering picture isn’t all that common, but it is known to happen in some cases. This could be a software or a hardware issue. Here’s what you can do.

Do a Picture Test

All Samsung LED TVs come with an inbuilt Picture Test.

  • Find this option under the Self Diagnosis heading inside the Support menu option of Settings.
  • Once activated, this test will prompt you with instructions that you’ll need to follow.
  • If the flickering persists, move to the next solution.

Perform an HDMI Cable Test

You won’t find this setting in every Samsung LED TV but all recent models will have it. Some models also get it after a software update.

This test is designed to check the integrity of HDMI cables, provided they’re less than two meters long.

  • Go to Settings and pick Support, followed by Self Diagnosis.
  • Choose Signal Information inside the new menu, and you’ll see HDMI Cable Test there.
  • Start the test, and if the results show a faulty HDMI cable, replace it and check for flickering again.
  • Remember to keep your TV’s source HDMI before starting this test.

Look for Grounding Issues

Sometimes, voltage fluctuations from the electrical wiring in your home can also cause flickering. This is a little difficult to fix, but it is possible.

  • Start by unplugging all other electrical appliances in your home.
  • Then, use an internal source like a USB drive to check the video quality.
  • If there’s no flickering, then one of the other appliances in your home was the cause.
  • One by one re-plug the other appliances and check for flickering in your television.
  • If the flickering comes back, you have your culprit.
  • If the flickering is there even with all other devices turned off, then there’s something wrong with the internal circuitry of your Samsung LED TV. This can only be fixed by a professional.

#3: Samsung LED TV Picture Dims on Its Own

It is very easy to confuse repeated dimming and brightening of the picture as flickering.

The automatic dimming or brightening is a result of an inbuilt feature of Samsung LED TVs.

The feature’s job is to adjust the brightness of your television according to the ambient lighting in the room.

This feature can be found under different names. Recent models will have this feature as Ambient Light Detection, while older ones will have it as an ECO Sensor or ECO Saving.

  • If your TV model is from 2016 or older, you’ll find the option to turn this feature off by going to System in Settings and selecting Eco Solution, followed by Eco Sensor.
  • If your model is from 2017 or newer, this feature will be found in General settings under the Ambient Light Detection heading.

#4: Samsung LED TV Picture is Cloudy

One of the most common problems with Samsung LED TVs is a cloudy or hazy picture, and you can fix it by changing some internal settings.

  • Start by reducing the backlighting.
  • Go to Picture Settings and choose Expert Settings. You’ll find Backlight there.
  • If reducing the backlight intensity doesn’t work, try changing the picture mode.
  • Go to Picture Settings and select Picture Mode.
  • Choose Natural in the submenu.

#5: Samsung LED TV Picture Freezes

If the picture in your Samsung LED TV is freezing, then the problem is obsolete software. You can remedy this by updating the operating system on the TV.

#6: Samsung LED TV is Not Connecting to Wi-Fi

If your Samsung LED TV is failing to connect to your Wi-Fi then the problem could be in your TV or your network gear.

The first thing you need to do to fix this issue is to check whether your network is listed in the TV’s settings.

Add Network to the TV

  • Go to Settings, select General, and then Network. Inside Network, you’ll find the Network Settings, which will have the Wireless option.
  • If your Wi-Fi network is not listed, then it may have become hidden by mistake. You’ll need to add it again to fix the problem. Select Add and then manually add the name of your network.
  • If the problem persists, reboot your TV and your router and perform the steps again.
  • If the problem still doesn’t go away, update the operating system of your TV.

If all else fails, you should reset your TV.

Reset your TV

  • Go to Support in the Settings menu and choose Self Diagnosis.
  • Inside, pick Reset and enter your PIN.
  • The default PIN in Samsung LED TVs is 0000.

#7: Apps Not Working on Samsung LED TV

This could be an issue with a single app or all the apps.

Update the App

If only one app is not working, you’ll need to update it.

  • Press the Smart Hub button and select Featured.
  • Find the app, highlight it, and hold the Enter key till a submenu opens.
  • Pick the Update App, wait for it to update, and then check if it opens.

Update the TV’s Operating System

If the app still doesn’t work, you’ll have to update the operating system of your Samsung LED TV.

The same solution applies if all the apps on your TV refuse to work.

Cold Reboot your TV

If updating all the apps and the TV software doesn’t help, you’ll need to cold reboot your TV. You can do this in two ways.

  • Press and hold down the Power button on the TV’s remote till the TV restarts.
  • Turn off the TV from the power source, unplug it, and wait for 30 seconds before turning it on again.


The most common problems with Samsung LED TVs are simple and can be fixed by tweaking the settings or cold rebooting the device.

If the problem persists even after all the tweaks and modifications suggested above, then it’s likely a hardware-related problem.

You’ll need a professional to help with those, so we recommend placing a service request with the company.
