Why Does My TV Keep Turning Off AND 10 FIXES:

The most common reason your Samsung TV keeps turning off is a problem with the TV settings or a connections error with external computer. However, we will look at ten additional reasons and their appropriate solutions.

1. out-of-date software

Most people are unaware that their television’s software needs to be updated. That is, if the software update is not set to automatically update. You must manually update the system.

If you haven’t been updating your TV software, this could cause your TV to turn off. Take the following steps to correct this:

  • Power on your TV 
  • Go to the Settings 
  • Select Support
  • Click on Software Update
  • Select Update Now

The update should take 30 minutes, but it could take longer or shorter depending on the strength of your network connections. During the update, the TV must not be turned off. If this occurs, your Samsung TV may sustain more severe damage. Check for updates on a regular basis to keep your Samsung TV up to date.

2. eco solution Settings 

Some Samsung TVs include eco-solutions settings, which you may have unintentionally activated. When there is no input for an extended period of time, this setting turns off your Samsung TV to save power.

This is another reason why your Samsung TV keeps shutting down. The solution is straightforward; simply turn it off by following the steps below.

  1. Using your remote, navigate to Settings.
  2. Choose General.
  3. Choose an eco solution.
  4. Choose Auto Power Off.
  5. Choose Off.

If this is why your Samsung TV keeps shutting down, you’ve just solved the problem. If it isn’t, keep going; you should be able to figure it out soon.

3. Sleep Timer Settings 

We can’t rule out the possibility that this setting is enabled because incorrect settings are one of the most common causes of your Samsung TV turning off. The Sleep Timer option turns off your TV after a predetermined amount of time.

You or another user of the Samsung TV could have turned it on. It is also simple to fix because everyone must turn it off. Carry out the following actions:

  • Go to Settings
  • Select General
  • Click on System Manager 
  • Select Time
  • Click on Sleep Timer
  • Select Off

4. Faulty Surge Protector

A surge protector is a computer that protects your electronic devices from power outages (caused by power outages from lightning or storms). If your surge protector is faulty, and your Samsung TV is connected to it, this could be the cause of the problem.

You can test the problem by bypassing the surge protector and plugging the TV power cord directly into a wall outlet. If your TV does not turn off on its own, you should replace or repair the surge protector (if possible).

5. connections Error

As previously stated, this is one of the possible and common causes of your Samsung TV turning off. This reason, however, can be caused by a variety of circumstances, including:

If your Samsung TV is connected to external devices such as game consoles and they suddenly shut down (due to a shaky connections), your TV may also shut down. You should unplug their power cables and turn them off before plugging them back in, ensuring they are properly connected.

If you use an uncertified HDMI cable, your samsung tv turns on and off repeatedly black screen due to a connecting error. If your Samsung TV continues to turn off as a result of this, use a certified HDMI cable method.

If your Samsung TV is not connected to any external computer but continues to turn off, check the settings and set the Sources to TV. Take the following steps to accomplish this;

  • Go to Settings on the TV
  • Select Sources
  • Select TV

6. Recalibration 

Your Samsung TV may need to be recalibrated from time to time to adjust for better functionality, and this may cause it to keep turning off. This can be accomplished by performing a factory reset.

All you have to do is unplug the Samsung TV from an outlet for 30 seconds, then plug it directly into a working outlet, and your TV is ready to go.

7. Defective Motherboard

The motherboard of any television is an important component of that television. It functions similarly to the main circuit board of your Samsung TV, controlling all processing. If your television has a faulty motherboard, it may continue to turn off on its own.

Unless you have technical skills, you cannot repair a faulty motherboard on your own. If your Samsung tv’s warranty is still valid, it is usually repaired at a Samsung authorized repair facility. This is an unusual cause for your television to keep turning off, but it cannot be ruled out.

8. Inferior Capacitor

Your Samsung TV may have a faulty capacitor, causing it to repeatedly turn off. A capacitor in your Samsung tv’s function is to supply power. As a result, if it is faulty or of poor quality, your Samsung TV may turn off repeatedly.

You can either replace the capacitor with a higher quality and efficiency capacitor or upgrade the inefficient one. You can do this if you have the necessary skills and knowledge, or you can seek the assistance of a professional.

9. Overheating

If your TV runs for an extended period of time without a break, it may be shutting down to prevent overheating. This is especially true if your video settings (Brightness, Contrast, Sharpness, and Color) are set to high values.

Overheating is harmful to your Samsung TV or any other television. Reduce the values for your video settings and turn off the TV yourself when not in use to prevent your Samsung TV from overheating and turning off.

10. Your Samsung TV remote may be misplaced

Although quite funny and unlikely, the remote to your Samsung TV may have been misplaced, and by some unconscious movements, the power button is turning off and on, thereby causing your TV to turn off by itself. It could be right under the couch you are seated on, and as you stand and sit, you are indeliberately controlling it.

To begin preventing heat, turn off your TV for a few minutes and check your power source. If your TV turns off after a few seconds or minutes, the heat is too high. After you restart it, reduce the video settings in the Menu / Picture settings to around 80% or less to see if the problem has been resolved. If this isn’t fixed, you may need to use your warranty, call a technician, or buy a new television!
