INPORTANT 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 DLP 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 DLP 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.

CONVERGENCE AND FOCUS ADJUSTMENT

» Start the convergence and focus adjustments with the top panel removed but the power

on. Use the remote control to adjust the image. Take the following procedures.

1. Focusing the projection lens

(A) Replacing all the 3 LCD panels

1. Before replacing all the 3 LCD panels, project an image on the screen and bring it into focus.

2. Replace the LCD panels with new ones. But until the focus has been completely readjusted, be careful not to change the projection distance between the set and the screen, nor to move the projection lens focus and zoom rings.

Note:

If the focus is readjusted with a different positional relation, the relation between the projection distance and the screen size is affected. In other words, a short-distance image (40 WIDE for example) may get out of the focus range, or a long-distance image (300 WIDE for example) may come out of the focus.

(B) Replacing 1 or 2 of the 3 LCD panels

1. In adjusting the focus after replacement of one or two LCD panels, project an image on the screen and turn the projection lens focus ring to get the non-replaced LCD panel into focus.

2. But until the focus has been completely adjusted for the new LCD panels, be careful not to change the projection distance between the set and the screen, nor to move the projection lens focus and zoom rings.

3. If the projection distance has been changed or the projection lens readjusted, repeat the above steps 1 and

2. Focus adjustment

(A) Adjusting the G-LCD panel(Make this adjustment on the white-only screen.)

1. Adjustment in θX and Z directions . Loosen the lock screw "a" and insert an eccentric screwdriver into the notch and hole "a". Turn the screwdriver until the top, center and bottom on the screen get into focus. In adjusting this top-to-bottom focus, tighten the lock screws "b" and "c" to fix the θY direction adjustment. First get the right and left halves in balance. Then improve the accuracy while making the adjustment 2 below.

2. Adjustment in θY direction T emporarily tighten the lock screw "a" and loosen the lock screws "b" and "c". Insert the eccentric screwdriver into the notch and hole "c" for adjusting in the θY direction on the top of the screen. Insert the eccentric screwdriver into the notch and hole "b" for adjusting in the θY direction on the bottom of the screen.

3. Repeat the above steps 1 and 2 to finely adjust the focus. Finally tighten up all the lock screws.

Notes :

1 Carefully proceed with the focus adjustment because the adjusting directions are correlated. 2 In adjusting the convergence and focus, do not move the projection lens zoom and focus rings until the end

of all the adjustments.

(B) Adjusting the B-LCD panel (Do the same for the R-LCD panel.)

1. Take the same procedure as for the G-LCD panel focus adjustment. Note that the adjustment range is wider in the Z direction. If the convergence is quite different between the B-LCD and G-LCD panels, roughly adjust the convergence first and then the focus.

3. Convergence adjustment

» Use a crosshatch pattern signal for this adjustment.

Make the adjustment just for the G-LCD and the relevant colour.

1. Loosen the convergence lock screw "d".

2. Adjustment in Y and θZ directions Put a hex wrench in the Y and θZ direction adjustment zone.

3. Adjustment in X direction Put an eccentric cam adjusting wrench in the X direction adjustment zone.

4. With the G-LCD panel's screen center as refernce, adjust the R-LCD and B-LCD panels.

5. Finally tighten up the convergence lock screw "d". Notes :

1 The eccentric cam is used for convergence adjustment.

This means that the cam's turning and the linear movement are not always uniform.

2 This model is not equipped with the LCD image adjustment mechanism. This is because the cross-dichroic

prism is used for image formation. When the LCD panels all get into best focus, the images are almost completely converged.

Adjusting the optical axis of the mirrors (M1, M5 and M4/M6)

The optical axis must be readjusted if an eclipse happens with the R. G or B mirrors. Generally speaking, this adjustment is needed when any of the internal optical components has been replaced.

Adjustment procedure required when any of the panels has been replaced or the convergence has been adjusted

(1)Disconnect the flat cables of all the LCD panels. (2)Let the lamp light up. (3)To adjust the G mirror, shield the R and B mirrors with shielding plates (You can use a business card or the like to

block the light). (4)Loosen the lock screw of the M1 adjust lever. (5)Looking at the G image on the screen, turn or slide the M1 adjust lever until the eclipse on the screen disappears.

Tighten up the screw. (6)To adjust the R mirror, shield the G and B mirrors and adjust the M5 adjust lever. For the B mirror , shield the R and

G mirrors and adjust the M6 adjust lever.

(Take the same steps 4 and 5 above.) (7)Remove all the shielding plates to have a white image.

Make sure there is no eclipse.
