About TV Temperature
When the TV is used for an extended period, the panel surrounds
become warm. You may feel hot when touching there by the
hand.

Precautions

Viewing the TV
• View the TV in moderate light, as viewing the TV in poor light or
during long period of time, strains your eyes.
• When using headphones, adjust the volume so as to avoid
excessive levels, as hearing damage may result.
OLED Screen
• Although the OLED screen is made with high-precision
technology and 99.99 % or more of the pixels are effective,
black dots may appear or bright points of light (white, red, blue,
or green) may appear constantly on the OLED screen. This is a
structural property of the OLED screen and is not a malfunction.
• Do not push or scratch the front filter, or place objects on top of
this TV set. The image may be uneven or the OLED screen may
be damaged.
• The screen and cabinet get warm when this TV set is in use. This
is not a malfunction.
• When disposing of your TV be sure to follow your local laws and
regulations.
Handling and cleaning the screen surface/
cabinet of the TV set
Be sure to unplug the AC power cord (mains lead) connected to
the TV set from AC power outlet (mains socket) before cleaning.
To avoid material degradation or screen coating degradation,
observe the following precautions.
• To remove dust from the screen surface/cabinet, wipe gently
with a soft cloth. If dust is persistent, wipe with a soft cloth
slightly moistened with a diluted mild detergent solution.
• Never spray water or detergent directly on
the TV set. It may drip to the bottom of the
screen or exterior parts and enter the TV
set, and may cause damage to the TV set.
• Never use any type of abrasive pad,
alkaline/acid cleaner, scouring powder, or volatile solvent, such
as alcohol, benzene, thinner or insecticide. Using such materials
or maintaining prolonged contact with rubber or vinyl materials
may result in damage to the screen surface and cabinet
material.
• Do not touch the TV if your hand is covered in any chemical
substance such as hand cream or sunblock.
• Periodic vacuuming of the ventilation openings is
recommended to ensure proper ventilation.
• When adjusting the angle of the TV set, move it slowly so as to
prevent the TV set from moving or slipping off from its table
stand.
Optional Equipment
Keep optional components or any equipment emitting
electromagnetic radiation away from the TV set. Otherwise
picture distortion and/or noisy sound may occur.

a place subject to direct sunlight, or a damp room.
Protecting the TV Screen (OLED TV)
Precautions to Protect the Screen from
Damage
Image retention
OLED TV's are susceptible to image retention (burn-in) due to the
characteristics of the materials used. Image retention may occur if
images are displayed in the same location on the screen
repeatedly or over extended periods of time. This is not a
malfunction of the TV. Avoid displaying images that may cause
image retention.
The following are examples of images that may
cause image retention:
• Content with black bars either on the top and bottom and/or
the left and right sides of the screen. (for example, Letterboxed,
4:3 screen, Standard definition)
• Static images such as photos.
• Video games that might have static content in some part of the
screen.
• On-screen menus, programme guides, channel logos etc.
• Static content from applications.
• On-screen tickers, such as those used for news and headlines.
To reduce the risk of image retention:
• Sony recommends that you turn off the TV normally by pressing
the power button on the remote control or the TV.
• Fill the screen by changing [Wide mode] to eliminate the black
bars. Select [Wide mode] other than [Normal].
• Turn off the OSD (On Screen Display) by pressing the
button, and turn off the menus from connected equipment. For
details, refer to the instruction manuals for the connected
equipment.
• Avoid displaying static images with bright colours (including
white), clocks or logos on any portion of the screen.
• Set the picture settings based on the ambient conditions. The
Standard Picture is recommended for home use and when
viewing content that often displays the station logos, etc.
The TV has following features to help reduce/ prevent image
retention.
Panel refresh
Panel refresh will automatically run to adjust the uniformity of the
TV screen after it has been in use for long periods of time. Panel
refresh can also be performed manually and should only be used
if image retention is very noticeable or you see the following
message: [Panel refresh did not finish...]
Caution:
• The Panel refresh function may affect the panel. As a reference,
perform the Panel refresh only once a year, do not perform it
more than once a year as it may affect the usable life of the
panel.
• Panel refresh 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.
• Panel refresh will only work when the room temperature is
between 10 ºC and 40 ºC.
Pixel shift
Automatically moves the image on the screen to prevent image
retention.
Other feature
The screen brightness is automatically reduced when displaying
still images, clocks, bright colours or logos etc.
