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. 

Check that your remote control does not have any foreign matter around the power button of the remote control. If the power button is stuck, clean the remote.

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 the Menu and select Support.

Step 2. Click About TV and check the Event logs.

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.

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)

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

Sometimes the TV turns on/off automatically when your connection is poor (AOC Tilt). In this case, thoroughly check all of the cable connections between the TV and One Connect Box (if in use).

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.

To reset your TV, head to Home > Settings > General > Reset
