1. Since it's on for 15 minutes head to the connections to the internet and turn that off or unplug the Ethernet cable.
2. Read the product manual and try all resets there.
3. Check your warranty and how where you bought it since Costco and CC's may extend the warranty period.
Hello!
Recently, our Samsung TV has been turning on after being turned off. We have tried removing ALL remote batteries (as we have several Samsungs in the house now) and have turned it off both with the remote and at the TV itself. The controls don't seem to be stuck anywhere that I can find, and it is quite a random occurrence, only happening every once in awhile. It will turn off automatically after 15 minutes, which is a setting that I had set, but immediately turns itself back on. Because of the positioning of our tiny living room, unplugging the TV from the outlet is a chore, and I was hoping someone could have some advice as to how to fix this problem. I'm at my wits end, and I apologize if there is another discussion that I could not find.
