How to troubleshoot the Samsung TV that keeps turning on by itself

The most common reasons for the TV to turn on by itself are having foreign matter around the power button of the remote control, external devices connected to the TV, and the settings. 

If the power button is stuck, clean the remote control.

 Check the Event logs

Sometimes abnormal power occurs due to external devices or the CEC command. In this case, by checking the TV history function, you can find what is making the TV turn on by itself.

Step 1. Go to Settings and select Support.

Step 2. Select About this TV then Event logs.

From the log history, you can figure out the reason for the issue, below are the possibilities reasons:

1.     “Power-on Reason” appears in the log history.

        If “Power-on Reason” appears in the log history with the below reason you could try the below:

·        “Power-on Reason, YouTube”: An app like YouTube or the SmartThings app on a device connected to the same AP could be the reason for the TV to turn on.

·        “Power-on Reason, Sensor”: Detected and operated by the brightness sensor set in Ambient Mode.

·        “Power-on Reason, WOL”: It means Wake On Lan, You should disable the Wake on LAN this way.

        Go to Control Panel > System > Power > Wake-on-LAN (WOL). Select Disable.

·        “Power-on Reason, BLE”: Check the Wake-up function on the devices paired with the TV by Bluetooth.

“CEC command” appears in the log history

• The CEC (Consumer Electronics Control) is a feature that enables you to control HDMI-connected devices with a single remote control.
• When an HDMI device activates, it may cause the TV to turn on. You can solve the issue by deactivating that feature.

Step 1. Go to Settings and select General.

Step 2. Select External Device Manager then enable Anynet+ (HDMI-CEC).

3.   “One Invisible Connection” appears in the log history.

Sometimes the TV turns on/off automatically when your connection is poor. In this case, disconnect and reconnect the One Invisible Connection or One Connect Cable to the TV and the One Connect Box. Ensure that the One Invisible Connection or One Connect Cable is not pinched or bent sharply.

If the above-mentioned methods do not work, there is also a factory reset that allows you to revert to the TV's original settings.

Step 1. Go to Settings and select General.

Step 2. Select Reset.
