HI Leo p, Thank you for purchasing the Samsung TU700D TV. I’m sorry to hear you’re experiencing a power cycling issue where your TV turns on and off repeatedly. Please try a few troubleshooting 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, then plug it back in. 4) If the power cycling allows enough time 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. The TV will likely need service if the issue persists after these steps. We back the TU700D with a 3-year limited manufacturer's warranty. You can see details of your warranty here: https://www.samsung.com/us/support/service/warranty/UN70TU700DFXZA Should you have additional questions or need to set up warranty service, please call us at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week.
