Why Does My Samsung TV Keep Turning Off
Various factors can contribute to your Samsung TV randomly turning off. Whether it’s due to hardware damage or software problems, it can be easily fixed in your home. Here are the most common reasons why your Samsung TV keeps turning off:
- Damaged Power Cable – To keep your smart TV turned on for a while, it needs a consistent supply of power from its source. Damaged power cables can interrupt the power flow and cause your Samsung TV to turn off. The same also applies to damaged wall sockets.
- Anynet+ (HDMI-CEC) is Enabled – The Anynet+ feature allows you to control HDMI-connected devices via the Consumer Electronics Control or CEC feature. This is mostly useful for home theater components. However, they can also partially control your smart TV, causing it to turn off randomly.
- Overheating – When your smart TV is put under extreme heat, it will automatically turn itself off. This is to protect your TV and its internal components from further damage and to avoid short circuits.
- Outdated Firmware – Glitches can occur once you don’t install the required updates for your Samsung smart TV’s OS. Checking for the latest updates can help solve this power issue. This can also fix Samsung Server Error 189.
- Hardware Damage – If your smart TV was bought a long time ago, chances are it may have sustained internal hardware damage. Components such as the main power board and motherboard are crucial to keeping your TV consistently turned on. Once these are damaged, it’s best to contact Samsung Support to get them checked professionally. This may also cause your Samsung Screen to go Black with No Picture.
How to Fix Samsung TV That Keeps Turning On and Off
Before going straight to the fixes for this problem, first, ensure that your TV’s power supply cord is in good condition; if it sustained tears and similar damage, it’s important to get it replaced immediately. If you have two or more sockets nearby, try plugging the power cord on the other sockets and see if it solves the problem.
If both the socket and the power cord are working properly, proceed to these fixes below. Remember to go through them individually and see which one works for you the best.
Fix #1: Power Cycle Your Samsung TV
Power cycling is a procedure that helps your TV’s internal components to reset and restore themselves to a stable state. This also eliminates bugs that can cause your Samsung TV to turn off randomly. To power cycle your Samsung TV, follow these steps:
- Turn off your Samsung smart TV and unplug it from its power source.
- Press and hold the Power button for two minutes. This is to drain all power that’s still on the TV’s internal components.
- After two minutes have elapsed, plug the power cord back into the socket and turn on your smart TV.
- See if it experiences the same problem.
Fix #2: Scan for Malware
Similar to your computer, your Samsung smart TV can also be infected by malware and other exploits. In rare cases, your smart TV can turn itself off once an infected app is opened or if it’s simply connected to the internet.
To scan your Samsung TV for malware, do the following:
- Turn on your smart TV. Using the remote, go to Settings > General > System Manager.
- Select Smart Security and choose Scan. Your smart TV will now be scanned for viruses and malware.
- Once it’s done, your TV will now reboot.
- Check if the same problem occurs.
Fix #3: Turn off Anynet+ (HDMI-CEC)
The Anynet+ (HDMI-CEC) feature is useful for various devices that are connected via HDMI. Although, it can also cause your smart TV to turn off as well once one or several HDMI-connected devices begin to turn off.
To turn off Anynet+ (HDMI-CEC) on your Samsung smart TV, follow the steps below:
- Using the remote, go to Settings > General > External Device Manager.
- Select Anynet+ and switch it to Off.
- Reboot your smart TV and check if it still turns off randomly.
Fix #4: Keep your Device in a Cool Environment
If you keep your device in a hot room or near direct sunlight, there’s a high chance that it experiences overheating issues. Your TV’s internal components need to maintain an optimal temperature to keep itself running consistently. So, it’s best to keep your smart TV in a well-ventilated area and see if it still experiences the same problem.
While transferring your TV, you can also check its vents for dust. Overheating can also occur once cold air is blocked from entering your TV’s internals due to clumped dust. You can clean your Samsung TV’s vents by using a small brush to dislodge dust and debris.
Fix #5: Update Your Samsung TV’s Firmware
Consistent firmware updates are critical for your smart TV to work normally and avoid glitches. Software updates can also contain fixes that can potentially solve this issue. To update your Samsung TV’s firmware, follow these steps:
- Using the remote, navigate to Settings > Support.
- Select Software Update and choose Update Software.
- Wait for your Samsung smart TV to download and install the latest software updates.
- After it reboots, see if it still turns off randomly or not.
This is also a recommended fix if your Samsung TV is not connecting to wifi.
Fix #6: Perform a Hard Reset
If all fixes don’t work, you can try performing a hard reset. This reverts your device and its configurations to its factory state. It also effectively deletes all user data and apps. To perform a hard reset on your Samsung smart TV, follow the steps below:
- Turn on your Samsung TV and go to Settings > Reset.
- Enter your PIN; if you still haven’t changed it, the default PIN is 0000.
- Choose OK. The smart TV will now reboot and start the hard reset process.
- Once it’s done, check if your Samsung TV still turns off randomly.
