With a Sony TV, there are Discrete power commands in the database, even though your original TV remote only has one power buton to cycle through Power On and Power Off.  In the setup select Devices, your TV, select Settings, select Adjust Power, select I want to turn this TV off when not in use, select One button for On and another button for Off, then for Power On select I don't have the original remote, but I know what he command is then from the drop down list of commands select PowerOn, do the same for Power Off and select PowerOff command from the list of commands, when you are done be sure you Update your remote.
