Disassembly cleaning
Disassembly cleaning method should only be performed when the unit is considerable
dirty and cannot be sufficiently cleaned by air spraying alone.
Be sure to readjust the optical system after performing disassembly cleaning.
1. Remove the cabinet top and main units following to “Mechanical Disassemblies”.
2. Remove the optical base top following to “Optical Unit Disassemblies”. If the LCD

Part 2: Repair Information
2-17
After long periods of use, dust and other particles will accumulate on
the LCD panel, prism, mirror, polarized glass, lens, etc., causing the
picture to darken or color to blur. If this occurs, clean the inside of
optical unit.
Remove dust and other particles using air spray. If dirt cannot be
removed by air spray, disassemble and clean the optical unit.
WARNING
The surface of the optical components consists of multiple dielectric
layers with varying degrees of refraction. Never use organic solvents
(thinner, etc.) or any kind of cleanser on these components.
Since the LCD panel is equipped with an electronic circuit, never use
any liquids (water, etc.) to clean the unit. Use of liquid may cause the
unit to malfunction.
CAUTION
Use a commercial (inert gas) air spray designed for cleaning camera
and computer equipment. Use a resin-based nozzle only. Be vary
careful not to damage optical parts with the nozzle tip. Never use any
kind of cleanser on the unit. Also, never use abrasive materials on the
unit as this may cause irreparable damage.
