Troubleshooting; Troubles And Solutions - Sony Bravia KDL-75W850C Reference Manual

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 主菜单 and
select [Help] t [System software
update] t [Automatic Software
Download] t [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 (mains lead) for two
minutes, then turn on the TV.
If the problem persists, contact your
dealer or Sony service centre with
the number of times the
Illumination LED flashes red
(interval time is three seconds).
Disconnect the AC power cord
(mains lead), and inform your
dealer or Sony service centre.
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] t [Self
Diagnostics]. If the problem
persists, have your TV serviced by
qualified service personnel.
