In a very few cases, you could see fine dots on
the screen while you’re viewing the TV. Those
dots are deactivated pixels and do not affect the
performance and reliability of the TV.
Generated Sound
Cracking noise A cracking noise that occurs when
watching or turning off the TV is generated by
plastic thermal contraction due to temperature
and humidity. This noise is common for products
where thermal deformation is required.
Electrical circuit humming/panel buzzing
A low level noise is generated from a high-speed
switching circuit, which supplies a large amount of
current to operate a product. It varies depending
upon the product. This generated sound does
not affect the performance and reliability of the

Take care not to touch the ventilation openings.
When watching the TV for a long period, the
ventilation openings may become hot. This does
not affect the performance of the product or cause
defects in the product.
Do not install this product on a wall if it could be
exposed to oil or oil mist. This may damage the
product and cause it to fall.
If the TV feels cold to the touch, there may be a
small flicker when it is turned on. This is normal;
there is nothing wrong with TV. Some minute dot
defects may be visible on the screen, appearing as
tiny red, green, or blue spots. However, they have
no adverse effect on the TV’s performance. Avoid
touching the LCD screen or holding your finger(s)
against it for long periods of time. Doing so may
produce some temporary distortion effects on the
screen.
Preventing image burn or burn-in
on your TV screen
If a fixed image displays on the TV screen for
a long period of time, it will be imprinted and
become a permanent disfigurement on the screen.
This is image burn or burn-in and not covered by
the warranty.
If the aspect ratio of the TV is set to 4:3 for a long
period of time, image burn may occur on the
letterboxed area of the screen.
Avoid displaying a fixed image on the TV screen
for a long period of time (2 or more hours for LCD,
1 or more hours for the Plasma TV) to prevent
image burn.

CHILD SAFETY:
PROPER TELEVISION PLACEMENT MATTERS
THE CONSUMER ELECTRONICS INDUSTRY CARES
• Manufacturers, retailers and the rest of the consumer electronics industry are committed to
making home entertainment safe and enjoyable.
• As you enjoy your television, please note that all televisions – new and old- must be supported on
proper stands or installed according to the manufacturer’s recommendations. Televisions that
are inappropriately situated on dressers, bookcases, shelves, desks, speakers, chests, carts, etc.,
may fall over, resulting in injury.
TUNE IN TO SAFETY
• A LWAY S follow the manufacturer’s recommendations for the safe installation of your television.
• A LWAY S read and follow all instructions for proper use of your television.
• NEVER allow children to climb on or play on the television or the furniture on which the television
is placed.
• NEVER place the television on furniture that can easily be used as steps, such as a chest of
drawers.
• A LWAY S install the television where it cannot be pushed, pulled over or knocked down.
• A LWAY S route cords and cables connected to the television so that they cannot be tripped
over, pulled or grabbed.
WALL OR CEILING MOUNT YOUR TELEVISION
• A LWAY S contact your retailer about professional installation if you have any doubts about your
ability to safely mount your television.
• A LWAY S use a mount that has been recommended by the television manufacturer and has a
safety certication by an independent laboratory (such as UL, CSA, ETL).
• A LWAY S follow all instructions supplied by the television and mount manufacturers.
• A LWAY S make sure that the wall or ceiling where you are mounting the television is appropriate.
Some mounts are not designed to be mounted to walls and ceilings with steel studs or cinder
block construction. If you are unsure, contact a professional installer.
• Televisions can be heavy. A minimum of two people is required for a wall or ceiling mount
installation.
MOVING AN OLDER TELEVISION TO A NEW PLACE IN
YOUR HOME
• Many new television buyers move their older CRT televisions into a secondary room after the
purchase of a at-panel television. Special care should be made in the placement of older CRT
televisions.
• A LWAY S place your older CRT television on furniture that is sturdy and appropriate for its size
and weight.
• NEVER place your older CRT television on a dresser where children may be tempted to use the
drawers to climb.
• A LWAY S make sure your older CRT television does not hang over the edge of your furniture.
