• Be sure the TV is vertical before turning on. To
avoid uneven picture uniformity do not power
on the TV with the panel facing down.
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 AC
power cord. Then press the power
button on the TV, and release it. Wait for
two minutes, and plug in the AC power
cord.
2
Refer to the Help menu by pressing
HELP
on the remote control.
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).
5
Perform the factory data reset.
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.
How to reset the TV to factory settings
WARNING: The reset will clear all of your
customized settings including the parental
lock setting.
• You can reset the TV to factory settings by
selecting [Factory data reset]. How to
select [Factory data reset], refer to the
Help Guide.
• To force factory data reset, unplug the AC
power cord. Press and hold
button on
the TV, then plug in the AC power cord.
• For security purposes, be sure to remove
all personal and account information
before discarding, selling or passing your
TV to someone else by: unlinking/
unregistering, signing out of and
deactivating all network services as well
as factory reset the TV.
The remote control does not function.
• Replace the batteries.
The parental lock password has been
forgotten.
• Enter 4357 for the PIN and enter the new
PIN.
The restricted profile password has been
forgotten.
• Perform the force factory data reset.
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 manually only when
image retention is particularly noticeable. As a
reference, perform it only once a year. Avoid
performing it more than once a year because it
may affect the usable life of the panel.
• Images that include clocks, logos and bright
colors (including white) easily cause image
retention. Avoid displaying these types of
images for long periods of time, otherwise
image retention may occur.
A white line appears on the screen.
• Panel refresh automatically runs after the
TV has been used for long periods of time
to reduce image retention. Panel refresh
starts after the TV is turned off and takes
about one hour to complete. A white line
may be displayed on the screen during
the Panel refresh. This is not a
malfunction of the TV.
