    THEORY THEORY This section covers what Liquid Crystals are and how an LCD Display works. LIQUID CRYSTALS In school you learned that matter has three distinct states; solid, liquid, and gas. However, there are states of matter that may fall between these states, like liquid crystals. Basically they are crystals that hold their orientation (shape) but can flow similar to liquids.

    THEORY LCD VERSUS CRT One disatvantage LCDs have is having fixed pixels which makes it more difficult to scale video than a CRT. A CRT can change the pixel size by adjusting the size of the beam, LCDs use a processor called a Scalar. LCDs feature their best picture quality at their native resolution (or max res) and CRTs feature good Scaled...

  • Page 39: Disassembly

    DISASSEMBLY DISASSEMBLY Models 23" and under have a similar internal layout and disassembly procedure. Therefore, the following disassembly instructions are divided into two parts. The first part covers the smaller screen LCDs (10"-23") and the other two parts cover large Sscreen LCDs (30” and up). The large screen disassembly instructions are broken into to two parts since some large screen models have a different internal layout.
  • Page 40 DISASSEMBLY Note: This model contains many screws. During each level of disassembly, keep the screws separated to ease reassembly. If desired, mark the screws and screw hole with different colored markers while disassembling. 1) Remove the cover and the stand. 2) Remove the back cover.
