Troubleshooting
In order to keep your TV software up-to-
date, it is necessary to download the latest
software information via the digital
broadcasting system or internet and to
update the software. Select [Update Now]
to start a software update. The illumination
LED flashes white while the software is
updating. Do not unplug the AC power cord
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 30
minutes. If you do not wish to update the
software automatically, press
HOME and
select [Help]

[System software update]

[Automatic software download]

[Off].
When you plug in 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, because it takes time to initialize the
system. Wait for about one minute, then
operate it again. When you turn on by
pressing the power button on the remote
control or the TV, it takes some time to turn
on the illumination LED and for the remote
control to be functional.
When the illumination LED is flashing red,
count how many times it flashes (interval
time is three seconds).
If the illumination LED flashes red, reset the
TV by disconnecting the AC power cord for
two minutes, then turn on the TV.
If the problem persists, contact Sony
Customer Support (information provided
on the front cover) with the number of
times the illumination LED flashes red
(interval time is three seconds). Disconnect
the AC power cord, and contact Sony
Customer Support.
When the illumination LED is not
flashing, check the items as follows.
You can also refer to [Troubleshooting] in

problem persists, contact Sony Customer
Support (information provided on the front
cover).
