What to do when Samsung TV keeps turning on and off?
For your convenience, there are many ways for your TV to connect with other devices and automatically turn on or off when needed. However, if your TV is turning off and on continuously, there are one or two simple actions you can take to fix it. The first step is unplugging the TV from the power source.
Unplug the TV from the wall outlet or surge protector and leave it unplugged for 30 seconds.
If you were using a surge protector, bypass it for now and use a wall outlet.
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 by the following steps:
- Go to Settings.
- Select Support.
- Click on Software Update and the Update Now.
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.
Important: By default, some HDMI devices are set to turn the TV on when they turn on. This feature is Anynet+, also known as HDMI-CEC, and allows you to control both devices with your TV remote. If you want to turn on your devices separately, you can turn off Anynet+ in Settings > General > External Device Manager, but you will no longer be able to use your TV remote for both devices.
