Hi Costcobuyer, Thanks for sharing your experience. If your TV is powering on by itself, there are a few settings and external triggers to review: 1. Power On with Mobile – Your TV may be connected to the SmartThings app or other networked devices. To stop wake signals, turn this feature off: Settings > All Settings > Connection > Network > Expert Settings > Power On with Mobile = Off 2. Check for Active Timers – Go to Settings > All Settings > General & Privacy > System Manager > Time > Timer Settings, then disable any On Timers or Sleep Timers 3. Anynet+ (HDMI-CEC) – If your TV is connected to external HDMI devices, one of them may be triggering power-on behavior. To disable this feature: Settings > All Settings > General & Privacy > External Device Manager > Anynet+ (HDMI-CEC) = Off 4. Software Update – Make sure your TV is up to date: Settings > Support > Software Update > Update Now If you’ve ruled out all the above and your TV still powers on unexpectedly, try unplugging it for 30 seconds. Should the issue continue, please call Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat is available under the ‘Support’ link on our website. ~ Samsung Advisor
