Does Your Samsung Smart TV Keep Restarting? Causes and How to Fix It!

Samsung is one of the trusted brands in the digital entertainment industry. Its array of electrical appliances includes the Samsung Smart TV, which is known to be durable and of very good quality. However, Samsung Smart TVs are not immune to faults and can therefore develop technical glitches from time to time. It is possible for your Samsung Smart TV to keep restarting by itself unexpectedly in the middle of your favorite TV show. 

If your Samsung Smart TV keeps restarting by itself, it probably means the power supply to TV is faulty or you have a loose power cable connection. Other reasons could be that there is a software glitch on your Samsung Smart TV or some hardware components in your TV are damaged. Software-related causes are easier to deal with since they can be fixed by resetting the Samsung TV factory settings. Fixing the hardware-related issues is a little bit tricky and normally requires replacing the damaged components. 

It can be very frustrating to find yourself in a situation where your TV keeps restarting. There are several other fixes that you can apply to your Samsung TV depending on the cause of the problem. What is important is that you troubleshoot the problem and identify its cause. In this guide, I will share with you some other probable causes and how to fix them, so read on for more techniques that you can use to get your Samsung TV that keeps restarting fixed.  

Why Does My Samsung TV Keep Restarting?

Your Samsung Smart TV may be restarting on its own due to the following reasons: 

  • Loose Power Cables or Faulty Power Supply
  • Outdated TV Software
  • Poor Internet Connection
  • Damaged motherboard or capacitor

Loose Power Cables 

Loose Power cables are major culprits when it comes to these things. If your power cable’s connection to an electrical socket or power source is loose or shaky, power flow to your TV will be interrupted and your Samsung will turn off by itself.

Similarly, if there is a fault with your power supply, an abnormal power surge, for example, power flow to your TV may be cut off, causing your TV to shut down and turn back on when the current flow is stable. 

Outdated TV Software

Samsung Smart TVs run on an operating system that needs to be constantly updated. Outdated software is normally full of bugs and technical errors that affect the operation of the TV. 

These errors also affect the functionality of your TV and can cause it to turn off unexpectedly.  

Poor Internet Connection

Your Samsung Smart TV uses an internet connection to check for automatic updates online if that is the setting you have on your TV. However, if the TV encounters internet connectivity issues as a result of poor internet connection, your Samsung Smart TV will keep restarting in order to complete the updates.

Damaged Motherboard or Capacitor 

The Samsung Smart TV’s motherboard is home to most of the important components of your TV. It houses the chips, circuits, and cables that are necessary for the operation of your TV. 

If the motherboard is faulty, there is a high possibility that these other components or circuits may be broken. This will eventually cause your TV to keep restarting. 

The capacitor is also one important component that is necessary for the power supply to your TV. If it breaks down or develops a fault, it will definitely affect the power supply to the other components of the TV, causing your TV to restart over and over again.

How to Fix a Samsung Smart TV that Keeps Restarting 

Fixing a Samsung TV that keeps restarting only becomes easier if the root cause of the problem is identified. To achieve this, you’ll have to troubleshoot the problem using any of the methods that I will be sharing below and apply the appropriate fix. 

The cause of the restarting issue may be software or hardware related. If it is software related, you can easily fix it by yourself. 

On the contrary, hardware-related issues, most often, involve a damaged internet component. To get it fixed, you’ll need the assistance of a professional TV technician to replace the component. 

Most of the time, these hardware components are expensive and the money you’ll spend in replacing them could rather be used to purchase a new TV. If your TV is still under warranty, you should contact Samsung for assistance with the TV repair work.

You can fix a Samsung Smart TV that keeps restarting by applying any of these techniques:

  • Check for loose power cables or faulty power supply 
  • Update TV software
  • Ensure a good internet connection
  • Power cycle your TV
  • Reset SmartHub
  • Reset TV to factory settings
  • Check for damaged motherboard or capacitor 

Check for Loose Power Cable 

The first thing you should do when your Samsung TV turns off or keeps restarting unexpectedly is to check around the TV for any loose power cable. Tighten the connection between the TV’s plug and the electrical socket or power source and then turn the TV back on to see if the issue is resolved. 

If you suspect a power surge or faulty, power supply, simply change the power supply where you plug in the TV’s cord and this, hopefully, should solve the problem. 

Update TV Software

Your Samsung Smart TV needs to always run on the latest version of its software in order to prevent disruptions by bugs or software errors. 

You can make things easier for yourself by setting the Samsung TV to check for automatic updates over the internet. These updates will be downloaded and installed automatically provided new versions are released. 

You should follow these steps to set the automatic updates: 

  1. Using the remote, go to Settings and choose Support.
  2. Go to Software Update and navigate to Auto Update
  3. Set the option to ON.

If you want to update the software yourself, follow these steps:

  1. Go to Settings and choose Support.
  2. Go to Software Update and choose Update Now. 

This will download the latest software and install it on your Samsung TV.

Ensure Good Internet Connection 

A strong and stable internet connection is very necessary when you want to use smart TVs such as the Samsung Smart TV.

You can choose between a wireless network such as WiFi or a cable network connection for your TV depending on which works best on the TV. 

  1. Press the Home button on your TV remote.
  2. Navigate to Settings and choose Network.
  3. Select Open Network Settings and choose which type you prefer, whether wired or wireless network. 

If you are using a router and you experience an unstable internet connection, you reboot your router and change the location if possible. 

You should also consider switching the cable connection to see if that helps the situation. 

Power Cycle Your TV 

Sometimes, your Samsung Smart TV may keep restarting because of memory glitches on your TV. What you can do is to power cycle the TV to clear these errors and start a new session. If you want to power cycle your TV, this is what you should do: 

  1. Turn off the TV and unplug it from its power source. 
  2. Press and hold the power button of the TV for about 30 seconds.
  3. Wait for another 30 seconds and then plug the TV back. 
  4. Turn on the TV.

This should help resolve the situation.

Reset SmartHub

SmartHub is the home of all the TV apps on your Samsung Smart TV. An app with errors may be compromised and may be the cause of the persistent restarting of the TV. If you can’t find that particular app to delete, you can reset the SmartHub to give your TV and the apps a new start. 

You can reset the SmartHub by following these steps: 

  1. Press the Menu button on your TV remote and go to SmartHub.
  2. Select Smart Hub Reset.
  3. You will be prompted to enter your PIN. Samsung TV’s default PIN is 0000 so enter this code when you are asked.
  4. The resetting process will be initiated.

When you are done resetting the SmartHub and the problem is solved, you can download all the apps that were previously on your SmartHub. 

Reset TV to Factory Settings 

Resetting your Samsung Smart TV to factory settings may be the only way to permanently get rid of all the errors on your TV. When you reset your TV to factory settings, you will wipe out all the settings, passwords, and data on your TV. 

This will restore it to the state in which it was when you bought it first.  

Follow the steps below to reset your Samsung TV to factory settings: 

  1. Navigate to Settings on your TV and choose General.
  2. Go to Reset and key in 0000 as the default PIN when prompted for a PIN.
  3. Select OK and press Enter

The TV will initiate the resetting process and your TV will be clean for a new start by the time it finishes.

Check for Damaged Motherboard Or Capacitor

Although this may not pleasant, sometimes, you will have to check for any damaged hardware components such as the motherboard or capacitor in your TV. When these components develop a fault the only to fix them is to replace them. Identifying whether they are in good condition or not is also tricky and will require the assistance of an experienced TV technician. 

One of the ways to detect faulty capacitors is to check whether or not the top is flat. If the top is not flat, it probably suggests that the capacitor is faulty. 

The cost of replacing some of these components is high and you may be better off buying a new TV rather than fixing them. 

Alternatively, you can get your TV fixed by Samsung if your TV is still under warranty. 

How Long Does a Samsung TV Last?

How long a Samsung Smart TV will last depends on how frequently it is used. Generally, Samsung TVs can last for as long as 7 years if it is being used all day every day. It may last shorter than this number of years though depending on several factors in the home such as power surges.

Does a Samsung TV Warranty Cover Restarting Problems?

Most Samsung TVs have a one-year warranty after you buy them. This warranty covers various potential faults which include restarting problems. 

The cause of the restarting problem should be genuinely not coming from you otherwise you will have to pay for the cost of repairs. 

Normally, you should have your receipts during the purchase with you when you want to get your TV fixed. 

Final Thoughts

You should not be surprised or worried when your Samsung Smart TV keeps restarting every now and then. A number of reasons comprising software and hardware-related issues may contribute to this problem.

Usually, it is much easier to fix software-related issues through a factory reset. The hardware-related cause may be a bit challenging for you so you need to contact an experienced technician to fix any damaged component in the TV. 

A better option will be to contact Samsung for warranty repairs if your TV is still under warranty.
