There were some software issues so call it in and ask about it. They will likely have you reset it and there are models that require Sam to do remote resets. As Samsung decided to implement a remote reset only they can perform that.

Hi,
From last few days my UE40F6320 40 Inch Full HD 1080p 3D Slim LED Smart WiFi TV is switching on by itself when on stand by mode. Whenever it does so, screen went black and sourrce change to "TV". Where as when I use "HDMI1" all the time.
It is changing to "TV" mode while on "HDMI1" while we are watching it.
Any idea what is causing it? Does it need any software update? or something faulty?
