LCD-Related Symptoms
LCD FRU Replacement Notice
The TFT LCD for the computer contains many thin-film
transistors (TFTs). A small number of missing, discol-
ored, 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 background is:
SVGA : 5 or more bright dots, 5 or more dark
dots, or a total of 9 or more bright and dark dots.
XGA : 8 or more bright dots, 8 or more dark dots,
or a total of 9 or more bright and dark dots.
