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 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 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

"Front-R/C, LED, DVi-TANi, terminal 2,Rear-R/C and key 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 you to use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldening bit, contact our service station or service ranch 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 wettabillty, 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 of f or the maximum heat-resistance temperature of parts may be excoeded, remove the bit from the PWB as soon as you conurm the steady soldering condition. Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to tum 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 after every use of it. When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.

Becareful when replacing parts with polarity indication on the PWB silk.

Function Light source. DC-driven high-pressure mercury vapor lamp. Used to absorb ultraviolet and infrared rays. Used to let the source light through the color filter and to separate it into R, G and B colors. Used to make for uniform light beams. Used to collect the light from the rod lens into the DMD chip. Used to reflect the light from the relay lenses against the DMD chip. Used to introduce the light from the reflector over the effective surface of the DMD chip. When the micromirror gets tilted (ON) as specified, the reflected light is guided to the projection lens. Used to turn on and off the micromirror in response to the ratio of color components at each dot and thus to reflect the incoming light accordingly. Used to enlarge the light from the DMD chip and to get the light projected on the screen.

Distinction between long and short focal length lens

• Long focal length lens: focus ring width: about 18 mm | XV-Z90U

• Short focal length lens: focus ring width: about 27 mm | DT-200 Caution when repairing without top cabinet To repair this set without top cabinet, attach the left side body beforehand. (Since the exhaust heat gets in around the set and the temperature sensor detects it giving the TEMP error and the lamp goes off.)
