Troubleshooting
General troubleshooting for issues like: black
screen, no sound, frozen picture, TV does not
respond, or network is lost, do the following
steps.
1
Restart your TV by pressing the power button
on the remote control for about five seconds.
The TV will restart. If the TV does not recover,
try unplugging the mains lead then press the
power button on the TV and release it. Wait
for two minutes, and plug in the mains lead.
Or, press the power button on the TV for
about 40 seconds until the TV turns off.

Refer to the Help menu shown below.
3
Connect your TV to the Internet and perform
a software update. Sony recommends you to
keep your TV software updated. Software
updates provide new features and
performance improvements.
4
Visit Sony support website (information
provided at the end of this manual).
When you plug in the 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.
It takes time to initialize the system. Wait for
about one minute, then operate it again.
The remote control does not function.
• Replace the batteries.
The parental lock password has been
forgotten.
• Enter 9999 for the PIN and enter the new PIN.
The screen becomes darker while watching
TV.
• If the whole image or part of the image
remains still, the screen brightness will be
gradually reduced to prevent image retention.
This is not a malfunction of the TV.
You are concerned about image retention.
If the same image is displayed repeatedly or for
long periods of time, image retention may
occur. To reduce image retention, we
recommend that you turn off the TV normally by
pressing the power button on the remote
control or the TV.
Note
• Perform Panel refresh only when image retention is
particularly noticeable. Avoid performing Panel
refresh more than once a year because it may affect
the usable life of the panel.
• Images that include clocks, logos and bright colours
(including white) easily cause image retention. Avoid
displaying these types of images for long periods of
time, otherwise image retention may occur.
The message [Panel refresh did not finish...] is
displayed.
When i) the TV is turned on or ii) the mains lead
is unplugged during the Panel refresh, the Panel
refresh is not completed. Please avoid the
above two conditions during the Panel refresh.

Guide.
