provided on the front cover of this manual).
When [A new TV system software update is

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

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
the TV.
It takes time to initialize the system. Wait for
