This SHARP projector uses a LCD (Liquid Crystal Display)
panel. This very sophisticated panel contains 786,432 pix-
els (
×
 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 accept-
able tolerances that the equipment must conform to.
This unit has some inactive pixels within acceptable toler-
ances which may result in inactive dots on the picture
screen. This will not affect the picture quality or the life ex-
pectancy of the unit.
* Temporary noise may be visible with vertical frequencies above 100Hz if OSD functions are activated.
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 0.15µF 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 Projector have
special safety-related characteristics.
These characteristics are often not evident from visual
inspection, nor can protection afforded by them be

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 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

NOTE TO SERVICE
PERSONNEL
 UV-RADIATION PRECAUTION
The light source,  metal halide lamp,  in the projector
emits small amounts of UV-Radiation.
AVOID DIRECT EYE AND SKIN EXPOSURE.
To ensure safety please adhere to the following:
1. Be sure to wear sun-glasses when servicing the
projector with the lamp
turned “on” and the top
enclosure removed.
2. Do not operate the lamp outside of the lamp housing.
3. Do not operate for more than 2 hours with the
enclosure removed.
UV-Radiation and Medium Pressure
Lamp Precautions
1. Be sure to disconnect the AC plug when replacing
the lamp.
2. Allow one hour for the unit to cool down before
servicing.
3. Replace only with same type lamp. Type BQC-
XGC50X//1 rated 85V/250W.
4. The lamp emits small amounts of UV-Radiation,
avoid direct-eye contact.
5. The medium pressure lamp involves a risk of
explosion. Be sure to follow installation instructions
described below and handle the lamp with care.

Lamp
Reflector
Comme de petites quantités de radiation UV sont
émises par une ouverture entre le couvercle du con-
duit et le botier de la lampe,il est recommandé de
placer le CAPUCHON D'OPTIQUE sur l'ouverture
pendant l'entretien pour éviter une exposition des
yeux et la peau.
Since small amounts of UV-Radiation are emitted
from an opening between the duct cover and the
lamp housing, it is recommended to place the LENS
CAP on the opening during servicing to avoid eye
and skin exposure.
DANGER !  –– Never turn the power on without the
lamp to avoid electric-shock or damage of the
devices since the stabilizer generates high voltages
at its start.
UV-RADIATION PRECAUTION (Continued)
Lamp Replacement
Note:
Since the lamp reaches a very high temperature
during units operation replacement of the lamp
should be done at least one hour after the power
has been turned off.  (to allow the lamp to cool off.)
Installing the new lamp, make sure not to touch the
lamp (bulb) replace the lamp by holding its reflector
2
.
[Use original replacement only.]
DANGER !  –– Ne jamais mettre sous tension sans
la lampe pour éviter un choc électrique ou des
dommages des appareils car le stabilisateur génère
de hautes tensions à sa mise en route.

Remplacement de la lampe
Remarque:
Comme la lampe devient très chaude pendant le
fonctionnement de l’unité, son remplacement ne doit
être effectué au moins une heure après avoir coupé
l’alimentation (pour permettre à la lampe de refroidir).
En installant la nouvelle lampe, s’assurer de ne pas
toucher la lampe (ampoule).  Remplacer la lampe en
tenant son réflecteur
