Troubleshooting; Troubles And Solutions - Sony BRAVIA KDL-75W855C Guide De Référence

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] 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 in red,
count how many times it flashes (interval
time is three seconds).
If the illumination LED flashes red, reset the TV
by disconnecting the 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 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.
