Samsung Smart TV allows you to stream your favorite shows and movies, listen to or play music, and even watch football. Sometimes, however, it can be difficult to use the device.
This happens when your Samsung TV turns on and off frequently. This behavior can occur at any time, even when you are playing video games or watching your favorite content.
Your Samsung Smart TV may keep restarting despite having the latest software installed or loose power cables.
Software problems can be fixed by a simple reboot. You can also inspect cables and repair them yourself.
If your Samsung TV does not turn on after you’ve tried these steps, then it could be because:
- Bulging capacitors
- A defective motherboard
- This device is currently updating its software.
- When updating its software, the device cannot establish an internet connection.
A short circuit on the power supply board could cause your TV to restart while streaming. This will cause a flashing light to appear all the time. This means that the problem is software- or hardware-based.
How do I troubleshoot a Samsung TV which keeps restarting?
We have the answers to your problem. You can try each one until you find the best one for you.
1. Update device software
Software updates are available for the Samsung Smart TV to fix bugs and add new features.
You can solve many problems with your device by keeping the software up-to-date, including frequent restarts. Here’s how it works:
- Go to Settings.
- Choose Support
- Choose Software Update
- Turn the Auto Update option ON by highlighting it.
These steps will automatically update the software. You can also upgrade the software online. This is how to do it:
- Go to Settings.
- Choose Support
- Click Software Update and then click Update Now.
Your device will automatically download and install new updates.
2. 2. Power cycle the device
A power cycle is used to reset the configuration parameters of the Samsung Smart TV. This allows the device’s unresponsive state to be restored.
It is possible to reset the computer and restart it if it is caused by network activity.
- Unplug your TV from the wall outlet.
- You should wait at least 60 seconds.
- Reconnect the cables.
Turn on the TV to see if it works.
3. Factory reset the TV
Factory resets will return your TV to its default settings. This will delete all files and data that could be causing the Samsung TV to boot loop. Here’s how it works:
- Open Settings.
- Select General
- Select Reset.
- Enter your PIN, or the default one, like 0000.
- Select Reset.
- To complete the reset, select OK
- Depending on the model, go to Settings > Support > Self Diagnosis and Reset.
The TV will automatically restart.
4. 4. Check the power cables
You will have frequent restart problems if the power cables are loose.
This can be corrected by connecting all power cables correctly and making sure they fit snugly. Switch on your device, and you will see if it works.
You may also want to reseat cables. This is an important step to take because dirt can get into the connections. It can cause resistance. To fix the problem, disconnect and reconnect the cords.
5. Check the capacitors
Your Samsung Smart TV might keep restarting because of faulty capacitors in its power supply. You can tell this problem in different ways.
- When you turn on your TV, the power supply will activate.
- The cap’s top is bulging, not flat.
Replace the capacitors with higher voltage ones if you see any of these symptoms. You should also replace the power supply board. It is best to hire an expert to do this.
6. Check the motherboard
Sometimes, the Samsung Smart TV will restart frequently due to a defective motherboard.
This can occur if one or more of the microchips on your motherboard stop working. The device will power on and off often. This issue can be fixed in one of two ways: repair or replacement.
It may appear easy and inexpensive to repair microchips that have been damaged. It is not an easy task and requires skill. Consider replacing the motherboard for a longer-term solution.
If your warranty is intact, contact Samsung customer support to help you replace it and ensure an effective Samsung TV power cycling fix.
7. Check your internet connection
You must ensure that your internet connection is stable if you have enabled automatic updates on your device.
But if your Samsung TV runs into network issues throughout this process, you will experience frequent restarts of the device. This issue can be fixed in a variety of ways.
- Restart the device by unplugging the Ethernet cable. Your TV won’t check for updates if there isn’t an internet connection. You might also consider turning off Wi-Fi to try again.
- You can switch to Ethernet if your device was originally wired to connect via Wi-Fi. Your TV will default to wireless when you connect Ethernet and disconnect Wi-Fi. It is possible for a network error to occur, which can lead to frequent restarts.
You can also reconnect to the internet to try again.
- Click the Home button on your remote.
- Choose Settings
- Select Network or General
- Open Network Settings.
You can choose between a wired or wireless connection.
8. Reset Smart Hub
Some users experience this problem after updates to the Samsung Smart TV Smart Hub. This could be your case.
- Visit Smart Hub.
- Choose the Smart Hub Reset.
- Select Reset Smart Hub.
Enter your PIN, or choose the default as 0000.
There are many reasons why your Samsung Smart TV keeps turning on or off every 5 seconds. It could be a defective capacitor or a damaged motherboard.
Other cases could involve the device software being out of date or recent Smart Hub updates. Try resetting Smart Hub or updating the firmware to resolve the issue.
