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
from the TV 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). Press the
 button on the TV to turn it off, 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).
