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.
The following screen with [Updating...] will
appear while software is updating.
Updating...
Do not unplug the AC power cord (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] [System
software update] [Automatic software
download] [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 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.
