LCD-related symptoms

Symptom-to-FRU index

Important: The TFT LCD for the notebook computer contains many thin-film transistors (TFTs). The presence of a small number of dots that are missing, discolored, or always lighted is characteristic of TFT LCD technology, but excessive pixel problems can cause viewing concerns. The LCD should be replaced if the number of missing, discolored, or lighted dots in any background is as follows:

Minimum quantity of defective pixels required for LCD replacement on June 2006 or later manufactured ThinkPad

WXGA+, SXGA+,	5	8	10
WSXGA+

Notes:

1.Lenovo will not provide replacement if the LCD is within specification as we cannot guarantee that any replacement LCD will have zero pixel defects.

2.A bright dot means a pixel is always on (white or color.)

3.A dark dot means a pixel is always off (black color.)

4.One pixel consists of R, G, B sub-pixels.
