LCD-Related Symptoms
Important
The 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.
