Hi Rail 179, If your TV turns on by itself, please try these troubleshooting steps. 1. Unplug the TV from the wall outlet or surge protector and leave it unplugged for 30 seconds. 2. Check the power cord to see if there is any visible damage. 3. Plug the TV power cord back into the wall outlet. If you were using a surge protector, bypass it for now and use a wall outlet. 4. Try to update the software. In some cases, a software update can correct the problem. There is a risk, however. If the TV turns off during the software update, it could damage the TV. Updates can take up to 30 minutes, depending on network speed, so if the TV is not turning off too frequently, try updating the software. 5. Disable the Power On with Mobile option. TVs that can connect to SmartThings can be turned on using compatible devices, sometimes automatically. However, if abnormal "power on" signals are sent through the wireless network, they will trigger this function and make the TV turn on. If you do not want this function, navigate to Settings > All Settings> General > Network > Expert Settings > Power On with Mobile, and turn the setting off. If the TV continues to turn on by itself continuously, please contact our Samsung Customer Support at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week. Our LiveChat agents are also available by clicking on the ‘Support’ link on our website. ~ Samsung Advisor
