Hello, Bluewaterslide. Welcome to the Samsung Community — we’re thrilled to have you here! If your TV has been mysteriously powering off and on, there's a handy way to get to the bottom of it. You can check your TV’s Event Logs, which act like a behind-the-scenes diary of your device’s activity. These logs can reveal exactly why each power cycle happened — whether it was a scheduled update, a signal issue, or something else entirely. Here's how to access and diagnose them.
Press the Home button on your Samsung remote. Navigate to Settings. Go to Support. Select About This TV. Choose Event Logs.
Once you're in the Event Logs, look for the “Power-on Reason.” This will tell you what caused the TV to turn on. Common reasons include:
CEC Command – A connected device (like a Blu-ray player or game console) sent a signal to turn on the TV. Scheduled Power On – A timer or routine was set to power on the TV at a specific time. Network Wake-up – The TV received a signal from a networked device or app (like SmartThings). Power Button Pressed – Someone physically pressed the power button on the remote or the TV itself.
How to fix it based on the reason:
CEC Command: Go to Settings > General > External Device Manager and turn off Anynet+ (HDMI-CEC). Scheduled Power On: Go to Settings > General > System Manager > Time and disable any timers. Network Wake-up: Go to Settings > General > Network > Expert Settings and turn off Wake-on-LAN or Mobile Access. Power Button Pressed: This may have been accidental—no further action needed unless it keeps happening. Hope this helps!
