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.
The following screen with [Updating…] will
appear while 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 the Help
Guide or perform self-diagnosis by selecting
[Help]
[Self diagnostics]. If the problem
persists, contact Sony Customer Support
(information provided on the front cover).
