Replacing The System Board - IBM ThinkPad S30 Hardware Maintenance Manual

LCD FRU Replacement Notice
The TFT LCD (XGA 10.4–inch) 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 background is: 5 or more bright dots, 5 or more
dark dots, or a total of 9 or more bright and dark dots.
