LCD replacement notice
The TFT LCD for the computer contains many thin-film
transistors (TFTs). A small number of missing, discolored,
or lighted dots (on all the time) 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 back-
ground is:
SVGA (12.1"): 5 or more bright dots, 5 or more dark
dots, or a total of 9 or more bright and dark dots.
XGA (14.1"/15.0"): 8 or more bright dots, 8 or more
dark dots, or a total of 9 or more bright and dark dots.
