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 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 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) from the TV 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]
[Self Diagnostics]. If the
problem persists, have your TV serviced by
qualified service personnel.
