(SOLVED) Why Does my Samsung TV Keep Turning OFF?


Why does my Samsung TV keep turning off?

The reason why a Samsung TV can keep turning off by itself is because the software is out of date, a faulty power supply, or because the user has enabled a sleep timer.

 

Causes

  • Outdated software
  • Power supply issue
  • Eco solution settings are turned on
  • You’ve enabled a sleep timer

 

Outdated Software

If you’re using an old software version on your Samsung TV, it is likely to have a lot of bugs. This runs the risk of your TV shutting down from time to time without any explanation.

 

Alternatively, there is another reason why your TV might be behaving this way that is related to your software. Most have the automatic software update setting enabled by default. When this is the case and a new update comes along, your TV will automatically start updating itself when connected to Wi-Fi. Once the update is complete, your TV will reboot itself to apply the changes. This can explain your TV shutting down without any reason.

 

Power Supply issue

Another potential reason why your Samsung TV may turn off on its own is related to power. Your TV is an electronic device that runs on power. If it doesn’t receive ample power to function normally, it will shut down.

If your TV is getting fluctuating power from the main supply, or if the power isn’t enough (perhaps due to a faulty cable), then your TV will Turn off for no reason.

 

Your TV’s Eco-solution settings are on

Eco solution is a new setting featured in selected Samsung TVs. This setting is intended to benefit the environment by saving power when it is not needed.

 

For example, if you don’t use your TV’s remote for a certain period of time, or there is no activity on your TV for a while, your TV will automatically shut down to save power, assuming that you’re no longer watching.

 

This will cause confusion for you if you accidentally enable this setting (or if some other person using the same TV enables it when you’re not around). The simple solution, of course, is to turn this off.

 

You’ve enabled a sleep timer

Sleep timers are pretty effective at helping you control your screen time. They ensure that you don’t lose track of time watching you’re your favorite shows back-to-back. When you’ve finished your screen-time quota for the day, your TV will automatically turn off without you triggering anything.

To fix this issue, you need to manually disable your sleep timer in the settings or increase the limit.

Why does my Samsung TV keep turning off on its own?

The reason why your Samsung TV might be turning off on its own is either because it’s recalibrating, it has a connection issue, or its motherboard is defective.

 

Recalibrating

Sometimes, your TV may need to recalibrate itself to function properly or to clear away any glitches that may arise. This cycle of recalibration may be causing your TV to shut down and restart automatically. A simple power reset is usually enough to resolve the issue.

 

Connection issue

When cables are loosely connected to your device, or when their ports are damaged, they send interrupted/ unstable signals to your TV. This can cause your TV to shut down automatically. Conduct a cable reset to resolve your issue.

 

Defective motherboard

The motherboard is the brain of your TV. Without it, your TV can’t do anything. So, if this component gets damaged, your TV will turn off and restart automatically until it can’t function. As soon as you notice this happening, call customer support to resolve this problem.

 

How do I stop my Samsung TV from turning off automatically?

You can stop your TV from turning off automatically either by resetting your TV, by cable resetting, or by calling customer support.

Cable reset your TV

Here are the steps:

  1. Turn off your Samsung TV
  2. Remove its power cord
  3. Now, take out all cables connected to your TV (especially the HDMI cable since there are the most common root of this issue)
  4. Clean these cables and ensure that they’re not damaged
  5. Place them back into their respective ports securely.
  6. Now turn on your TV and see whether the issue is solved.

 

Call customer support

In the case where your TV’s motherboard has deteriorated, you have no choice but to call Samsung’s customer support to take a look at your TV and tell you your options. Alternatively, you could also call an expert technician for the job but only do so if you’re ready to give up on your TV’s warranty.

 

Why does my Samsung TV’s backlight turn off on its own?

The reason why your Samsung TV’s backlight is turning off on its own is either because you’ve enabled the ambient light detection feature or your TV’s backlight is damaged.

 

Ambient light detection

The ambient light detection feature dims your TV’s lights if the surrounding lighting is low enough. Your TV’s backlight will also go dim- giving you the illusion that it is turning off. This especially happens when your TV makes an error while detecting the surrounding lighting.

 

Damaged Backlight

Backlights are responsible for showing the visuals you see on TV. If they get damaged, they may start malfunctioning during use and turn off randomly.

 

How do I turn on My Samsung TV’s backlight?

You can turn on your TV’s backlight by going to the settings and adjusting the brightness.

 

  1. Find and press the menu option on your TV’s remote
  2. Find picture settings
  3. Go to backlight
  4. Adjust the brightness from there

 

Why does my Samsung TV blink before turning off?

If your TV blinks a white light before turning off, it is a sign that one of the cables isn’t properly connected (especially the HDMI cable).

 

If the cables connected to your TV aren’t fit into the ports properly (or have deteriorated), they might send mixed, interrupted signals to your device. This will cause the screen to flash.

To resolve this problem, try conducting a cable reset on your device.

 

  • Turn off your Samsung TV
  • Remove its power cord
  • Now, take out all cables connected to your TV (especially the HDMI cable since there are the most common root of this issue)
  • Clean these cables and ensure that they’re not damaged
  • Place them back into their respective ports securely.
  • Now turn on your TV and see whether the issue is solved.
