BenC: Thank you for purchasing the Samsung TU7000 TV. I am sorry to hear that you are experiencing a power cycling issue where your TV is turning itself on and off repeatedly. Please try a few trouble-shooting steps that may help solve the issue: 1) Check the power cable for damage and proper connection. 2) If the cable is bent, broken, kinked, pinched, pressed excessively (possibly by a heavy object on top of it) or damaged, this is likely the cause of the issue. Replace the cable. 3) Unplug the TV from the wall outlet for 30 seconds, and then plug it back in. 4) If the power cycling allows enough time in between powering on and off, try updating the TV to the latest firmware. 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) TVs which 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 > General > Network > Expert Settings > Power On with Mobile, and turn the setting off. If the issue persists after these steps, then the TV will need service. Please contact us so that we can better investigate your issue and assist you towards a solution or replacement. 1-800-SAMSUNG (ask for TVs), available 8AM -12AM EST, 7 days a week Or visit us on the Samsung website and click on the ‘Support’ link in the upper right corner of the homepage for: 1) Contact Us Options (LiveChat, Remote Support, Facebook, Twitter) 2) Product Support 3) Manuals and Downloads 4) Warranty Info 5) Product Registration: Registering your product gives you access to easy warranty support, convenient opt-in to special promos and offers, faster troubleshooting and service, and quick notification of system updates 6) Samsung Community: A great resource for getting help from Samsung moderators and customers and more 7) …and more product, repair, order, and care options ~ Samsung Solutions
