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

The most common reasons for the TV to turn on by itself is having foreign matter around the power button of the remote control, external devices connected to the TV, and your settings. If the power button is stuck, clean the remote control. To check your external device connections, please follow the steps below. 

Sometimes abnormal power occurs due to external devices or the Consumer Electronics Control (CEC). In this case, by checking the TV history, you can find out what is causing the TV to turn on by itself.

Step 1. Go to the Menu and select Support.

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

If Power-on Reason appears in the Event Log, you can check why the TV turned on. Your TV can be powered on by mobile apps, sensors, BT, and voice. You can solve the problem by disconnecting or deactivating the connected devices that operate the TV.

• 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.

• Sensor - Detected and operated by the brightness sensor set in Ambient Mode.

• WOL - Turned on by eMac phy (Magic Packet) function.

• BLE - Turned on by the Wake up function of a Bluetooth device. 

2. “CEC command” appears in the log history

The CEC feature 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.

Home > Settings > General > External Device Manager > Anynet+ (HDMI-CEC)

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.

Home > Settings > General > Reset
