IMPORTANT SERVICE SAFETY NOTES
n Service work should be performed only by qualified service technicians who are
thoroughly familiar with all safety checks and servicina auidelines as follows:
BEFORE RETURNING THE PROJECTOR:
(Fire & Shock Hazard)
Before returning the projector to the user, perform
the following safety checks:
1.
2.
3.
0
0
Inspect lead wires are not pinched between the
chassis and other metal parts of the projector.
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.
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 0.15uF capacitor in parallel
between all exposed metal cabinet parts and earth
ground.
WARNING
1. For continued safety, no modification of any circuit
should be attempted.
2. Disconnect AC power before servicing.
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 “A”
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.
De nombreuses pieces, electriques et mecaniques, dans
AVIS POUR LA SECURITE
les projecteur a LCD presentent des caracteristiques
speciales relatives a la securite, qui ne sont souvent
pas evidentes a vue.
Le degre de protection ne peut pas etre necessairement
augmentee en utilisant des pieces de remplacement
etalonnees pour haute tension, puissance, etc.
Les pieces de remplacement qui presentent ces
caracteristiques sont identifiees dans ce manuel;
les pieces electriques qui presentent ces particularites
sont identifiees par la marque “A” et hachurees dans la
liste des pieces de remplacement et les diagrammes
schematiques. Pour assurer la protection, ces pieces
doivent etre identiques a celles utilisees dans le circuit
d’origine. L’utilisation de pieces qui n’ont pas les memes
caracteristiques que les pieces recommandees par
I’usine, indiquees dans ce manuel, peut provoquer des
electrocutions, incendies ou autres accidents.

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
CLMPF0053DE05 rated 65V/155W.
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.
-WLamp 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.)

n Cleaning the lenses and reflectors
1. Lens cleaner
l Cleaning liquid:
Change the mixture ratio of alcohol and ether depending on ambient
temperatures. Make sure that the liquid evaporates from the lens
surface immediately after you rub it: This is the best ratio. The more
ether is used, the quicker the liquid evaporates.
l Method:
Use well-washed bleached cotton cloth or cleaning paper available
on the market. Damp the bleached cotton cloth with the liquid, and
hold the lens sandwiched in the cloth with your thumb and the index
finger. Turn the lens and wipe the surface clean from the center
outward to collect dust. Be careful not to rub the coated surface too
strong.

H Controlling the total operating hours of the lamp
The following control is carried out when the lamp has been used for 1900 hours and 2000 hours.
1. After 1900-hour use
2. After 2000-hour use
3.
4..
When the power is turned on, “LAMP” appears in the on-screen display for about 1 minute (flashing in yellow)
and the lamp LED indicator lights up in red.
When the 1900-hour point comes up during use of the unit, the “LAMP” display starts flashing in yellow on the
screen for 1,minute at the very 1900-hour point.
Now the lamp LED indicator changes from green to red.
When the power is turned on, “LAMP” appears in the on-screen display for 5 minutes (flashing in red) and the
lamp LED indicator lights up in red. Five minutes thereafter, the power turns itself off and the unit is interrupted.
When the 2000-hour point comes up during use of the unit, the “LAMP” display starts flashing in red on the
screen for 5 minutes at the very 2000-hour point. Five minutes later, the power turns itself off and the unit is
interrupted. (The lamp LED indicator stays red since the 1900-hour point.)
If you try to turn on the power twice after the 2000-hour point, the unit remains off.
When the 2000-hour point comes up, take the following steps.
Replace the lamp with new one. While holding down both the “VOLUME Y’ and “SELECT/ADJ v” Keys on the
unit, turn on the main power switch (located on the back of the unit). The lamp operating hourmeter is now reset
to zero. Turn on the unit and make sure the time display shows “OOOOH”.
Displaying the total operating hours of the lamp
Change the STATUS3 data settings: PICTURE at 0, BRIGHT at MAX, COLOR at MIN, TINT at MIN, and
SHARPNESS at MAX. Hold down the SOUND DOWN and ENTER keys for longer than 2 seconds. By doing
this, the total operating hours will be displayed on the screen.
