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 A C voltage
drop across the resistor (See Diagram).

» All checks must be repeated with the AC plug

connection reversed. (If necessar y, 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.

Precautions for using lead-free solder

1 Employing lead-free solder

"PWBs" of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on the
PWBs and service manuals. The alphabetical character following LF shows the type of lead-free solder.

Example:

L Fa

Indicates lead-free solder of tin, silver and copper.

2 Using lead-free wire solder

When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional
lead wire solder may cause damage or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40°C, we recommend y ou
to use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldering bit,
contact our service station or service branch in your area.

3 Soldering

As the melting point of lead-free solder (Sn-Ag-Cu) is about 220°C which is higher than the conventional lead solder
by 40°C, and as it has poor solder wettability, you may be apt to keep the soldering bit in contact with the PWB for
extended period of time. Ho we v er, since the land may be peeled off or the maximum heat-resistance temperature of
parts may be exceeded, remove the bit from the PWB as soon as you confirm the steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to turn on
and off the power of the bit as required.
If a different type of solder stays on the tip of the soldering bit, it is allo yed with lead-free solder. Clean the bit after
every use of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.

Be careful when replacing parts with polarity indication on the PWB silk.
