Why my Samsung TV turns on by itself ?

If your Samsung TV turns on by itself, you may be wondering what is causing this problem and how to prevent it from happening again.

Consequently, there are several possible reasons as we mentioned above why your TV could turn on without your command.

For example, such as faulty remote control, power fluctuations, timer settings, or software updates.

Therefore, in this section, we will help you find the exact reason why your Samsung TV turns on by itself and suggest some solutions.

• Firstly, access “Settings” on your Samsung TV.

• Secondly, select “Support” and then click “Diagnostics.”

• Next, choose “Self Diagnosis” and run a diagnostic test on the TV.

• Then, once completed, return to “Support” and select “About this TV.”

• Furthermore, click “Status Message” to view the event log history.

• Finally, review the power-on reasons and CEC command messages listed.

Common reasons for logging on may include mobile apps, sensors, voice commands from devices like Alexa, or VT functionality. For example, these indicate that an interacting connected device could be the culprit.

Furthermore, a CEC command in the list means that an HDMI-connected device is potentially controlling the TV. As a result, you can disable CEC by adjusting the external device manager settings.

Then, if the log mentions a poor connection or “One Invisible“, carefully check all cable connections to the TV.

Specifically, viewing the event log history can help determine if remote controls, timers, software, or interactive devices are the root cause of unwanted auto-on behavior.

How to troubleshoot a Samsung TV that turns on by itself?

You’ve found the exact reason why your Samsung TV turns on by itself, but how do you fix it?

Consequently, depending on the cause of the problem, there are different solutions you can try to prevent your TV from turning on randomly.

Therefore, in this section, we will show you how to fix Samsung TV that turns on by itself and restore your peace of mind.

Follow below mentioned methods to fix Samsung TV turns on by itself:

Clean the Remote and Check Its Battery

A common cause for a Samsung TV to turn on unexpectedly is a problem with the remote control.

If the remote control appears to be the cause, try the following steps to fix the problem:

• First, examine the power button on the remote control. See if it gets stuck or feels slow when pressed.

• Then, check the remote control batteries. Low battery may cause random signals. As a result, replace them with new alkaline batteries.

• Next, as a test, try programming the TV to a different remote to see if the problem persists with the original remote.

Examining the buttons and batteries on the remote is a good starting point for addressing unwanted activation due to remote issues.

​Disable Sleep Timer

The sleep timer feature on Samsung TVs is designed to automatically turn off it after a set period of time.

However, this could cause the TV to turn on unexpectedly if the timer is enabled.

Therefore, to check if the sleep timer is causing unwanted power cycles and disable it if so:

• First, press the “Home” button on your remote control.

• Next, navigate to the left and select “Settings.”

• Then, go to “General” and then “System Administrator.”

• After that, select “Timers” from the menu options.

• Furthermore, here you will find the “Sleep Timer” and “Sleep Timer” settings.

• Finally, check if any of the timer options are set to turn the TV on or off at a certain time.

If a sleep or active shutdown timer is set, disable it by turning off the setting. Disabling the sleep timer feature will prevent you from unintentionally turning the TV on or off on a schedule.

Disable Smart Things

SmartThings is a connectivity platform that allows you to control and automate compatible smart home devices from your phone. Consequently, some Samsung TVs are integrated with SmartThings functionality.

Specifically, if enabled on the TV, SmartThings allows any linked devices in your home, such as smart lights, locks, or thermostats, to potentially turn on the TV remotely via the SmartThings app or automated routines.

Follow below mentioned steps to disable Smart things:

• First, press the Settings button on your Samsung TV remote control.

• Next, go to General > Network > Expert Settings.

• Then, select “Turn on with mobile“.

• Finally, disable this option so that smart devices can no longer turn on the TV remotely.

Disabling this SmartThings integration setting will ensure that the TV does not automatically turn on when other linked smart home products are activated through the SmartThings platform.

Update Software

Keeping your Samsung TV software updated is important for functionality, performance and security. Furthermore, uninstalled updates could also cause unexpected reboots.

Specifically, pending software updates may trigger automatic restarts that power cycle the TV unexpectedly.

Follow below mentioned steps to update software of your Samsung Smart TV:

• First, press the Settings button on your Samsung TV remote control.

• Next, navigate to  Support > Software Update.

• Then, select “Update Now” and the TV will automatically check for the latest firmware version.

• Furthermore, if an update is available, you will be prompted to install it.

• Finally, follow the on-screen instructions to download and install the update package.

Alternatively, you can select the “Automatic Update” option. Consequently, this will automatically download and install any critical updates in the background without the need to update manually.

Samsung TVs can act strangely due to power and cable issues. To check this, follow below mentioned steps:

• First, look for damage or scratches on the power cord. Replace if necessary.

• Next, test whether the power supply can meet the voltage needs of the TV. Specifically, larger TVs may require more power.

• Then, use a voltage regulator to prevent high or low voltage spikes that could affect the TV’s power controls.

• Finally, make sure the power is stable and cables are intact. This may rule out electricity as the cause of the problem.

Reduce temperature of your Samsung TV

Your TV may become too hot if the airflow and ventilation are not sufficient.

Consequently, to lower the temperature of your Samsung television, follow below mentioned steps to reduce the temperature of your Samsung TV:

• First, unplug the TV and wipe any dust from the back of the TV with a dry microfiber cloth.

• Then, move the TV to a room with more air circulation properly clearing dust buildup and ensuring adequate airflow helps prevent overheating.

Turn Off Eco-Solution settings

If your Samsung TV turns on unexpectedly, check the Eco-Solution or auto-off settings that are intended to conserve power:

• First, press the “Settings” button on your Samsung TV remote control.

• Next, navigate to “General” in the main settings menu.

• Then, select “Eco Solution” within the General menu.

• After that, choose the “Auto Power Off” option.

• Finally, change the setting to “Off” so that the TV does not automatically turn off after periods of inactivity.

Reset your Samsung Smart TV

On some Samsung TV models, problems may arise during the automatic calibration process, which aims to optimize display settings.

Consequently, this could cause the TV to turn off unexpectedly and repeatedly. As a result, to resolve this issue, it is recommended to perform a factory reset on your Samsung TV.

Unplug the Samsung TV or Projector

To fix the Samsung TV turning on and off issue, follow below mentioned steps:

• Initially, disconnect the TV or projector from the power source or surge protector.

• Next, leave it unplugged for 30 seconds.

• Then plug it back into the power supply.

• Finally, see if the TV still turns itself on and off.

Check the source

Make sure the TV source is selected on your device most of the time. This can prevent the Samsung TV from turning on and off randomly.

Follow below mentioned steps to select source input on your Samsung TV:

• ​First, press the Settings button on your Samsung TV remote control.

• Next, navigate to “Source” in the main settings menu.

• Then, select the “TV” option from the list of available inputs.

Disable Power On with Mobile option

Some Samsung TVs integrate with SmartThings, allowing compatible mobile devices to control power functions. However, while convenient, this can cause problems if any irregular signals are received.

Follow below mentioned steps to disable this feature:

• First, press the Settings button on your Samsung TV remote control.

• Next, navigate to “General” and then “Network” > “Expert Settings”.

• Then, select “Turn on with mobile” and disable the option.

Disabling this connectivity feature prevents any paired mobile device from unintentionally sending power commands to turn the TV on or off. If no solutions work for you, contact Samsung Support.

Disable Anynet+ (HDMI-CES)

HDMI-CEC allows your connected home entertainment devices to work together seamlessly. Through HDMI-CEC, devices can share control signals over the HDMI cable.

Furthermore, this means you can use your TV remote to control a connected Blu-ray player or game console.

For example, the play, pause and skip functions on the TV remote control will control video and audio playback from the Blu-ray player.

In addition, the devices can also automatically switch inputs on the TV. Therefore, your Blu-ray player can tell the TV to switch to the HDMI input it is connected to when you turn it on.

Moreover, many devices are set at the factory to automatically turn on the TV when they are turned on. Samsung calls this feature Anynet+, which is the name they give to HDMI-CEC.

Consequently, if your TV turns on by itself unexpectedly, HDMI-CEC is likely the cause. As a result, you should check your device settings to see if the auto power on feature can be disabled to prevent unwanted activation of the TV.

If you want to disable the HDMI Auto On feature on your Samsung TV, you can follow these steps:

• Firstly, press the Menu button and navigate to Settings, followed by System.

• Secondly, select HDMI-CEC and set Device Auto On, Device Power On, and TV Auto On all to Off.

This should prevent your TV from switching inputs or turning on devices when you don’t want it to.
