The TFT LCD for the notebook computer contains many
thin-film transistors (TFTs). 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:
SVGA (12.1 in.): 5 or more bright dots, 5 or more
dark dots or a total of 9 or more bright and dark dots.
XGA (13.3 in.): 8 or more bright dots, 8 or more dark
dots or a total of 9 or more bright and dark dots.
