Why Does My Samsung TV Keep Turning Off?

Samsung Tv

What could be causing your TV to switch itself on or off? Is a genie remote-controlling it from a distance? Are you suddenly in a horror movie? Any electronic turning itself on or off could be alarming. But the problem shouldn’t be too far from the ordinary, so switch off that alarm.

Most electronic devices, even the best, like Samsung televisions, could intermittently develop faults we are usually too inattentive to notice. Sometimes, the problem could result from a mistake while tinkering with the remote.

Whatever the problem is, we are here to help you figure them out.

Reasons Your Samsung TV Keeps Going Off

There are countless reasons your Samsung device might be turning itself off. Sometimes, you could fix these problems with the press of a button. Other times, you might have to open up your TV. These problems could be split into two categories: hardware and software problems.

Hardware Problems

These issues directly affect the components of your Samsung TV — from power surges to overheating. They could either require you to open your Samsung TVs (or the services of an expert) or need only a few outside replacements.

Faulty Motherboard

Many occurrences could render your Samsung TV’s motherboard non-functional. One principal reason is a power surge resulting from a lightning storm or other electrical anomaly. A surge or a few of these electrical surges pack up enough energy to damage the capacitors attached to the motherboard.

Since these capacitors control the electricity that eventually keeps your TV on, a damaged one is a probable reason why your TV is abruptly going off. In this case, the available solution is to get a new set of capacitors installed by a technician. However, if you feel like you can handle the task of replacing them, you could:

  1. Open the Television’s rear cover (screws should be holding it down).
  2. Look for the motherboard; it is usually what takes up most of the space at the back of your TV.
  3. Now you should see a set of more prominent cylindrical components attached to the board.
  4. The bad ones are usually swollen; take them out and replace them.

Insufficient Power

Usually, your Samsung TV, like all modern TVs, functions perfectly on a wattage within the range of 10 to 117. So, it is natural when it switches off because it is not getting sufficient juice.

The problem could either be:

  • from your plug, which you could easily check out with a technician.
  • your cord, which you might need to replace.
  • a damaged surge protector.
  • a damaged extension cable/box.
  • or from the socket that simply might not be producing enough electricity to power your Samsung TV.

You could quickly test the socket’s capacity by plugging in another device and observing whether it works. If it does not, you might want to check out your socket. In the meantime, you could plug your TV into a different outlet. Hopefully, the other outlet should handle the TV just fine.

Software problems

Software issues are the most common among numerous things that could be wrong with your Samsung TV. These problems could result from forgetting to disable a specific TV setting or an incompatible gadget. It is often not that serious since these issues are easy to fix.

The Aynet+ Setting Is Active

In Samsung TVs, HDMI ports are integrated with one software: Aynet+. The Aynet+ software gives both your TV and external HDMI-linked devices a degree of control over one another. To illustrate this point, your TV might have gone blank because a connected device went off. If this is the problem, you might need to deactivate this setting. To do this:

  1. Press the Home key on the TV remote.
  2. Locate the Settings option and select it.
  3. Select General.
  4. Navigate for the External device manager.
  5. Click on the Aynet+ choice, then disable it (Off).

Your TV Needs Its Software Updated

Your Samsung TV, like other devices, might just need an update. To achieve this:

  1. Pick up the remote and press the Home button.
  2. Choose Settings out of the options.
  3. Then pick out the Software update under Support.
  4. You can now “Update now.

Your System Is Set To Go Off

Most Samsung TVs come with an Eco-mode, which helps save energy. The reason why your TV went off could be this setting. To deactivate it:

  1. Click on the Home button, then Settings.
  2. Now, select General > Eco Solution.
  3. Then, select Auto power off.
  4. Turn it Off.

Malware Attack

Your TV might’ve just picked up malware. The easiest way to resolve this will be to reset your TV. To achieve this:

  1. Open your Menu and navigate to Settings > General.
  2. Choose the Reset option.
  3. Type in your PIN.
  4. Initiate the process by selecting Ok.


Your Samsung TV might suddenly go off due to an effect on either hardware or software. While the hardware might require you to fix specific components, the software might only need a remote and a few simple procedures.
