This SHARP projector uses LCD (Liquid Crystal Display)panels.These
very sophisticated panels contain 786,432 pixels (
×
RGB)TFTs (Thin
Film Transistors).As with any high technology electronic equipment
such as large screen TVs,video systems and video cameras,there
are certain acceptable tolerances that the equipment must conform
to.
This unit has some inactive TFTs within acceptable tolerances which
may result in illuminated or inactive dots on the picture screen.This
will not affect the picture quality or the life expectancy of the unit.
If you have any questions about this matter,please call toll free 1-888-
GO-SHARP (1-888-467-4277). U.S.A.ONLY
Specifications are subject to change without notice.

IMPORTANT SERVICE SAFETY NOTES (for USA)
Ë
Service work should be performed only by qualified service technicians who are
thoroughly familiar with all safety checks and servicing guidelines as follows:
WARNING
1. For continued safety,  no modification of any circuit
should be attempted.
2. Disconnect AC power before servicing.
BEFORE RETURNING THE PROJECTOR:
(Fire & Shock Hazard)
Before returning the projector to the user,  perform
the following safety checks:
1. Inspect lead wires are not pinched between the
chassis and other metal parts of the projector.
2. Inspect all protective devices such as non-metallic
control knobs, insulating materials, cabinet backs,
adjustment and compartment covers or shields,
isolation resistor-capacity networks, mechanical
insulators, etc.
3. To be sure that no shock hazard exists, check for
current leakage in the following manner:
»
Plug the AC cord directly into a 120-volt AC outlet,
(Do not use an isolation transformer for this test).
»
Using two clip leads, connect a 1.5k ohm, 10 watt
resistor paralleled by a 0.15
µ
F capacitor in parallel
between all exposed metal cabinet parts and earth
ground.
»
Use an AC voltmeter with sensitivity of 5000 ohm per
volt.,  or higher,  sensitivity to measure the AC voltage
drop across the resistor (See Diagram).
»
All checks must be repeated with the AC plug
connection reversed.  (If necessary,  a non-polarized
adapter plug must be used only for the purpose of
completing these checks.)
Any reading of 0.3 volts RMS (this corresponds to
0.2 milliamp. AC.) or more is excessive and indicates
a potential shock hazard which must be corrected
before returning the unit to the owner.

SAFETY NOTICE
Many electrical  and  mechanical parts in LCD Projector
have special safety-related characteristics.
These characteristics are often not evident from visual
inspection, nor can protection afforded by them be
necessarily increased by using replacement components
rated for higher voltage, wattage, etc.
Replacement parts which have these special safety
characteristics are identified in this manual; electrical
components having such features are identified  by “
å
and  shaded  areas in the Replacement Parts Lists and
Schematic Diagrams.  For continued protection,
replacement parts must be identical to those used in the
original circuit.  The use of a substitute replacement parts
which do not have the same safety characteristics as
the factory recommended replacement parts shown in
this service manual, may create shock,  fire or other
hazards.
AVIS POUR LA SECURITE
De nombreuses pièces, électriques et mécaniques, dans
les projecteur à LCD présentent des caractéristiques
spéciales relatives à la sécurité,  qui ne sont souvent
pas évidentes à vue.
Le degré de protection ne peut pas être nécessairement
augmentée en utilisant des pièces de remplacement
étalonnées pour haute tension, puissance,  etc.
Les pièces de remplacement qui présentent ces
caractéristiques sont identifiées dans ce manuel;
les pièces électriques qui présentent ces particularités
sont identifiées par la marque “
å
” et hachurées dans la
liste des pièces de remplacement et les diagrammes
schématiques.  Pour assurer la protection, ces pièces
doivent être identiques à  celles  utilisées dans le circuit
d’origine.  L’utilisation de pièces qui n’ont pas les mêmes
caractéristiques que les pièces recommandées par
l’usine, indiquées dans ce manuel, peut provoquer des
électrocutions, incendies ou autres accidents.
WARNING: The bimetallic component has the primary
conductive side exposed. Be very careful in
handling this component when the power is on.
AVERTISSEMENT: La composante bimétallique dispose du
conducteur primaire dénudé. Faire
attention lors de la manipulation de cette
composante sous tension.
