LCD anomaliesGo to : Pixel anomalies
A certain number of pixel anomalies are inherent in liquid crystal display technology and vary by many factors, including type of
technology.
Many anomalies observed by customers are considered normal or are the result of lint or dust particles resting on the front of the
display. It is important to understand what type of anomaly a customer sees in order to determine whether further analysis is
necessary. In many cases all that may be necessary is a gentle cleaning of the display face using the provided cleaning cloth.
IMPORTANT : Providing a replacement display to satisfy a customer may not be effective because the
replacement display may have more or different types of visible anomalies than the original display,
and still be within specifications.
Knowledge Base Article 22194 can be indicated to customers as public explanation from Apple side.
Industry standards used by all manufacturers are specifying a certain number of minor defects, as generally accepted or
creating an acceptable situation. This means that the level of quality in the industry includes some level of pixel-defect.
The following sentences can be used with customers’ complains
Copied from SONY documentation (Sony VAIO web Support)
• High precision technology is used to manufacture these LCDs to maintain a high standard of operation. However in all LCD
panels there may be a small number of pixels that do not change color. This is a normal occurrence for all LCD displays from all
manufacturers and should not be noticeable or objectionable under normal operation.
• Sometimes the pixels are noticeable only during booting or on an all white or all black screen.
• The LCD screen is manufactured using high precision technology. However, there may be some tiny black spots and/or bright
spots (red, blue or green in colour) that constantly appear on the LCD screen. These spots occur normally in the manufacturing
process and do not effect the recorded picture in any way. Effective number of pixels is 99.99% or more.
Copied from COMPAQ documentation (Compaq FAQ on Compaq’s web Support)
• Note that if you have the smallest number of dead pixels, your replacement display panel may have more, use your judgement
before deciding that you have a defective panel.
Copied from DELL documentation (Dell web : http://support.euro.dell.com/fr/fr/kb/document.asp?DN=FA1018431)
• The liquid crystal display (LCD) screens built into portable computers and flat-panel monitors are manufactured using rigid
quality control standards. These manufacturing standards ensure that the LCD screen is clear and viewable.
• During the manufacturing process, it is not uncommon for one or more pixels to be fixed in an unchanging state. The visible
result is a fixed pixel that appears as an extremely tiny discolored spot, either a dark spot or a bright spot.
Copied from TOSHIBA documentation (Toshiba web Support)
• Due to current manufacturing methods and the high number of transistors in the TFT Color LCD, a few nonconforming pixels
may be visible. There are over a million transistors in a typical TFT screen. When any one of those transistors is not lighting as
designed, the pixel is called nonconforming. Nonconforming pixels typically appear as tiny colored dots (red, blue, green, etc.)
or as black dots in contrast to the projected background color of the LCD module.
• Quality inspections, performed by the LCD module manufacturers, include limits for nonconforming pixels. Nonconforming pixel
limits (10 to 18 pixels) are set solely by the LCD module manufacturers and not by specific computer manufacturers. These
limits are defined by the manufacturing processes and are specific to screen characteristics which include :
* physical size of module.
* display type (SVGA, XGA, VGA).
* screen resolutions available.
• LCD Module manufacturers continually strive to upgrade processes used in manufacturing as well as the Quality Specifications
which include the limits on nonconforming pixels allowed for LCD modules for use in portable computer displays.
(End
Pixel anomalies
When speaking with Apple Technical Support, it may be necessary to use a pocket microscope, jeweler's loupe, or other
magnifying device to properly identify and count each subpixel anomaly.
Displaying all white, red, green, and blue screens makes locating and viewing pixel anomalies easier.
A subpixel that is always on should be referred to as a bright subpixel anomaly. A subpixel that is always off should be referred
to as a dark subpixel anomaly.
When necessary, portable and display products may be dispatched for evaluation by the Apple Repair Center.

10. Touch a metal surface on the inside of the computer to discharge any static electricity, as shown (Figure 5).
Important : To avoid electrostatic discharge damage, always ground yourself by touching the computer’s framework before
you touch any parts or install any components inside the computer. To avoid static electricity building back up in your body,
do not walk around the room until you have completed the installation and closed the computer.
Removing the Installed Memory Card
1. If your computer has the optional AirPort Card installed, unlatch the flexible wire holder that secures the card (Figure 6).
2. Use the pull-tab on the card to remove it from the slot. (You do not need to disconnect the antenna.)
Note : To avoid scratching the computer’s case, place a sof t cloth between the AirPort Card and the surface of your iBook.
3. If an AirPort Card is not installed, unlatch the flexible wire holder to release the AirPort Card antenna cable.
4. Remove the screws that secure the RAM shield (Figure 7).

5. Lift the RAM shield out of the computer. Carefully pulling up on the wire holder may help to remove the shield (Figure 8).
6. Locate the installed memor y card and brackets that secure the card on both sides (Figure 9).
7. Carefully spread the brackets apart until the card releases on each side. Pull the card up and out of the memory slot.
Installing the Replacement Memory Card
1. Line up the notch in the replacement memory card with the small tab in the memor y slot. Hold the card at a 30-degree

2. Gently push the top of the card down until the brackets snap onto both sides of the memory card to lock it into place
(Figure 11).
3. Insert the RAM shield (Figure 12).
4. Verif y that the end of the wire of the wire holder (where it is attached to the RAM shield, on the keyboard side) does not
catch on the side of the compartment. The screw holes on the shield and computer should align and the shield should lay
uniformly flat.
5. Verif y that the AirPort antenna cable routes through the notch in the RAM shield without pinching.
6. Replace the RAM shield screws.
7. If you do not have an AirPort Card, flip down the wire holder over the AirPort Card antenna cable and secure it by inserting
the prongs of the holder into the slots in the RAM shield (Figure 13).
