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 mains
lead 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 unplug the TV and plug it in again,
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 10 to 20
seconds, then operate it again.
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.
