IMPORTANT SERVICE SAFETY NOTES (for USA)
CService 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.
SAFETY NOTICE
Many electrical and mechanical parts in DMD™
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
DVM

TEST PROBE
components having such features are identified by " "
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.
CAUTION: FOR CONTINUED PROTECTION
AGAINST A RISK OF FIRE REPLACE ONLY
WITH SAME TYPE F701 (6.3A, 250V)
• Use an AC voltmeter having with 5000 ohm per volt,
or higher, sensitivity or measure the AC voltage drop
across the resistor.
• Connect the resistor connection to all exposed metal
parts having a return to the chassis (antenna, metal
cabinet, screw heads, knobs and control shafts,
escutcheon, etc.) and measure the AC voltage drop
across the resistor.
All checks must be repeated with the AC cord plug
connection reversed. (If necessary, a nonpolarized
adaptor plug must be used only for the purpose of
completing these checks.)
Any reading of 0.75 V peak (this corresponds to 0.5
mA peak AC.) or more is excessive and indicates
a potential shock hazard which must be corrected
before returning the monitor to the owner.
BEFORE RETURNING THE PROJECTOR:
(Fire & Shock Hazard)
Before returning the receiver to the user, perform
the following safety checks:
1. Inspect all lead dress to make certain that leads are
not pinched, and check that hardware is not lodged
between the chassis and other metal parts in the
projector.
2. Inspect all protective devices such as non-metallic
control knobs, insulation materials, cabinet backs,
adjustment and compartment covers or shields,
isolation resistor-capacitor networks, mechanical
insulators, etc.
3. To be sure that no shock hazard exists, check for
leakage current in the following manner.
• Plug the AC cord directly into a 120 volt AC outlet. (For
North America)
• Plug the AC cord directly into a 110 ~ 240 volt
AC outlet, and connect the DC power cable into
the projector's DC jack. (Do not use an isolasion
transformer for this test). (For Others)
• Using two clip leads, connect a 1.5k ohm, 10 watt
resistor paralleled by a 0.15µF capacitor in series
with all exposed metal cabinet parts and a known
earth ground, such as electrical conduit or electrical
ground connected to an earth ground.

AVIS POUR LA SECURITE
De nombreuses pi es, électriques et mécaniques, dans
les projecteur à DMD™ présentent des caractéristiques
spéciales relatives à la sécurité, qui ne sont souvent
pas évidentes à vue.
Le degré de protection ne peut pas re nécessairement
augmentée en utilisant des pi es de remplacement
étalonnées pour haute tension, puissance, etc.
Les pi es de remplacement qui présentent ces
caractéristiques sont identifiées dans ce manuel;
les pi es électriques qui présentent ces particularités
sont identifiées par la marque " " et hachurées dans
la liste des pi es de remplacement et les diagrammes
schématiques. Pour assurer la protection, ces pi es
doivent re identiques à celles utilisées dans le circuit
d’origine. L’utilisation de pi es qui n’ont pas les m es
caractéristiques que les pi es recommandées par l’
usine, indiquées dans ce manuel, peut provoquer des
électrocutions, incendies ou autres accidents.
PRECAUTION: POUR LA PROTECTION
CONTINUE CONTRE LES RISQUES D'INCENDIE,
REMPLACER LE FUSIBLE PAR UN FUSIBLE DE
MEME TYPE F701 (6.3A, 250V)
•Utiliser un voltm re CA d'une sensibilité d'au moins
5000Ω/V pour mesurer la chute de tension CA en
travers de la résistance.
•Toucher avec la sonde d'essai les pi es métalliques
exposées qui présentent une voie de retour au
châssis (antenne, coffret métallique, t e des vis,
arbres de commande et des boutons, écusson, etc.)
et mesurer la chute de tension CA en-travers de la
résistance. Toutes les vérifications doivent re refaites
apr avoir inversé la fiche du cordon d'alimentation. (Si
nécessaire, une prise d'adpatation non polarisée doit
re utilisée dans le but de terminer ces vérifications.)
La tension de pointe mesuée ne doit pas dépasser
0.75V (correspondante au courant CA de pointe de
0.5mA).Dans le cas contraire, il y a une possibilité
de choc électrique qui doit re supprimée avant de
rendre le récepteur au client.

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:
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 40ºC, we recommend
you 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 220ºC which is higher than the conventional lead
solder by 40ºC, 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. However, 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 solder-
ing 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 alloyed with lead-free solder. Clean the bit af-
ter 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.
LFa
Indicates lead-free solder of tin, silver and copper.

RESETTING THE TOTAL LAMP TIMER
About the lamp indicator
■When the remaining lamp life becomes 5% or less, (yellow) and “Change The Lamp” will be
displayed on the screen. When the percentage becomes 0%, it will change to (red), the lamp will
automatically turn off and then the projector will automatically enter standby mode. At this time, the
lamp indicator will illuminate in red.
■If you try to turn on the projector a fourth time without replacing the lamp, the projector will
not turn on.
About the temperature warning indicator
If the temperature inside the projector increases, due to blockage of the air vents, or the setting location,
“” will illuminate in the lower left corner of the picture. If the temperature keeps on rising, the lamp
will turn off and the temperature warning indicator will blink, the cooling fan will run, and then the projec-
tor will enter standby mode. After “ ” appears, be sure to perform the measures described on page
53.
Lamp indicator
■The warning lights (power indicator, lamp indicator and temperature warning indicator) on the
projector indicate problems inside the projector.
■If a problem occurs, either the temperature warning indicator or the lamp indicator will illuminate
red, and the projector will enter standby mode. After the projector has entered standby mode,
follow the procedures given below.

• If the temperature warning indicator illuminates, and the projector enters s tandby mode, follow the
pos s ible s olutions above and then wait until the projector has c ooled down c ompletely before plug-
ging in the power cord and turning the power back on. (At least 10 minutes.)
• If the power is turned off for a brief moment due to power outage or some other cause while using
the projec tor, and the power s upply rec overs immediately after that, the la mp indic ator will illumi-
nate in red and the lamp may not be lit. In this case, unplug the power cord from the AC outlet,
replac e the power c ord in the AC outlet and then turn the power on again.
• The cooling fan keeps the internal temperature of the projector constant and this function is con-
trolled a utomatic ally. The s ound of the c ooling fa n ma y c ha nge during opera tion bec a us e the fan
speed may change and this is not a malfunction.
• D o not unplug the p ower c ord a fte r the proje c tor ha s entere d s ta ndby mode a nd while the c ooling
fan is running. The cooling fan runs for about 90 s econds.
