LCD-Related Symptoms
Important
The TFT LCD for the notebook computer contains
over 2,359,296 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 background is 21 or
more.
