Visit Sony support website (information
provided on the front cover of this manual).
When [A new TV system software update is
available...] message is displayed.
Sony strongly recommends you to update the
TV software by selecting [Update Now]. These
software updates improve your TV performance
or add new features.
The following screen with [Updating...] will
appear and the illumination LED flashes white
while software is updating.
Do not unplug the mains lead during the
software update. If you do, the software update
may not finish completely, and it may cause a
software malfunction. Software updates can
take up to 15 minutes.
When you plug in the TV, the TV may not be
able to turn on for a while even if you press
the power button on the remote control or

It takes time to initialize the system. Wait for
