I'm having trouble factory resetting my Samsung smart TV without a remote. I'm trying to set up my Xbox one and its connected via HDMI but when I go to the HDMI source on the smart TV it says: "there is no device connected" and don't even go to the channel. I have read about this online and people have said to factory reset the TV. But my Samsung Smart TV only has one button and that's the power button. Please help me. Thanks you.
