I have a Sony Bravia KLV 46-BX450. It turns on automatically after a few seconds after I turn off it. When turn on, it says: ''TV has been turn on by On Timer" but according to the Manual Guide and the TV setting, there is no "On Timer". Now, I don't know how to turn off my TV. Please help me, thanks.

I did it but it doesn't work. And my TV firmware is non-upgradable because it's an old TV.
