Important Safety Notice

Read and understand all instructions before you use your TV. If damage is caused by failure to follow instructions,

the warranty does not apply.

Safety

 Risk of electric shock or fire!

 Never expose the TV to rain or water. Never place liquid containers. Such as vases, near the TV. If liquids

are split on or into the TV, disconnect the TV from the power outlet immediately. Contact Philips Consumer

Care to have the TV checked before use.

 Never place the TV, remote control or batteries near naked flames or other heat source, including direct

sunlight. To prevent the spread of fire, keep candles or other flames away from the TV, remote control and

batteries at all time.

 Never insert objects into the ventilation slots or other openings on the TV.

 When the TV is swiveled ensure that no strain is exerted on the power cord. Strain on the power cord can

loosen connections and cause arcing.

 Risk of short circuit or fire!

 Never expose the remote control or batteries to rain, water or excessive heat.

 Avoid force coming onto power plugs. Loose power plugs can cause arcing or fire.

 Risk of injury or damage to the TV!

 Two people are required to lift and carry a TV that weights more than 25 kg.

 When stand mounting the TV, use only the supplied stand. Secure the stand to the TV tightly. Place the TV

on a flat, level surface that can support the combined weight of the TV and stand.

 When wall mounting the TV, use only a wall mount that can support the weight of the TV. Secure the wall

mount to a wall can support the combined weight of the TV and wall mount. Koninklijke Philips Electronics

N.V. bears on responsibility for improper wall mounting that result in accident, injury or damage.

 Risk of injury to children! Follow these precautions to prevent the TV from toppling over and causing injury to

children:

 Never place the TV on a surface covered by a cloth or other material that can be pulled away.

 Ensure that no part of the TV hangs over the edge of the surface.

 Never place the TV on tall furniture (such as a bookcase) without anchoring both the furniture and TV to the

wall or a suitable support

 Educate children about the dangers of climbing on furniture to reach the TV.

 Risk of overheating! Never install the TV in a confined space. Always leave a space of at least 4 inches around

the TV for ventilation. Ensure curtains or other objects never cover the ventilation slots on the TV.

 Risk of damage to the TV! Before you connect the TV to the power outlet, ensure that the power voltage

matches the value printed on the back of the TV. Never connect the TV to the power outlet if the voltage is

different.

 Risk of injury, fire or power cord damage! Never place the TV or any objects on the power cord.

 To easily disconnect the TV power cord from the power outlet, ensure that you have full access to the power

cord at all times.

Meridian 4

 When you disconnect the power cord, always pull the plug, never the cable.

 Disconnect the TV from the power outlet and aerial before lightning storms. During lightning storms, never touch

any part of the TV, power cord or aerial cable.

 Risk of hearing damage! Avoid using earphones or headphones at high volumes or for prolonged periods of

time.

 If the TV is transported in temperatures below 5℃, unpack the TV and wait until the TV temperature matches

room temperature before connecting the TV to the power outlet.

Screen Care

 Avoid stationary images as much as possible. Stationary images are images that remain on-screen for

extended periods of time. Examples include: on-screen menus, black bars and time displays. If you must use

stationary images, reduce screen contrast and brightness to avoid screen damage.

 Unplug the TV before cleaning.

 Clean the TV and frame with a soft, damp cloth. Never use substances such as alcohol, chemicals or household

cleaners on the TV.

 Risk of damage to the TV screen! Never touch, push, rub or strike the screen with any object.

 To avoid deformations and color fading, wipe off water drops as soon as possible.

4.3 Pixel Defect Policy

Philips strives to deliver the highest quality products.

We use some of the industry's most advanced

manufacturing processes and practice stringent quality

control. However, pixel or sub pixel defects on a flat

monitor panel are sometimes unavoidable. No

manufacturer can guarantee that all panels will be free

from pixel defects, but Philips guarantees that any

monitor with an unacceptable number of defects will be

repaired or replaced under warranty. This notice

explains the different types of pixel defects and defines

acceptable defect levels for each type. In order to

qualify for repair or replacement under warranty, the

number of pixel defects on a monitor panel must

exceed these acceptable levels. For example, no more

than 0.0004% of the sub pixels on a monitor may be

defective. Furthermore, Philips sets even higher quality

standards for certain types or combinations of pixel

defects that are more noticeable than others. This

policy is valid worldwide.

Pixels and Sub pixels

A pixel, or picture element, is composed of three sub

pixels in the primary colors of red, green and blue.

Many pixels together form an image. When all sub

pixels of a pixel are lit, the three colored sub pixels

together appear as a single white pixel. When all are

dark, the three colored sub pixels together appear as a

single black pixel. Other combinations of lit and dark

sub pixels appear as single pixels of other colors.

Types of Pixel Defects

Pixel and sub pixel defects appear on the screen in

different ways. There are two categories of pixel

defects and several types of sub pixel defects within

each category.

Bright Dot Defects: Bright dot defects appear as

pixels or sub pixels that are always lit or 'on'. That is, a

bright dot is a sub-pixel that stands out on the screen

when the monitor displays a dark pattern.

These are some types of bright dot defects:

13

Meridian 4

One lit red, green or blue sub pixel

Two adjacent lit sub pixels:

- Red + Blue = Purple

- Red + Green = Yellow

- Green + blue = Cyan (Light Blue)

Three adjacent lit sub pixels (one white pixel)

Note:

A red or blue bright dot must be more than 50 percent

brighter than neighboring dots while a green bright

dot is 30 percent brighter than neighboring dots.

Black Dot Defects: Black dot defects appear as pixels

or sub pixels that are always dark or 'off'. That is, a

dark dot is a sub-pixel that stands out on the screen

when the monitor displays a light pattern. There are

some types of black dot defects:

Proximity of Pixel Defects

Because pixel and sub pixels defects of the same type

that are near to one another may be more noticeable,

Philips also specifies tolerances for the proximity of

pixel defects.

Pixel Defect Tolerances

In order to qualify for repair or replacement due to pixel

defects during the warranty period, a Philips flat

monitor panel must have pixel or sub pixel defects

exceeding the tolerances listed in the following tables.
