NOTE TO SERVICE PERSONNEL

UV-RADIATION PRECAUTION

The light source, metal halide lamp, in the LCD

projector emits small amounts of UV-Radiation.

AVOID DIRECT EYE AND SKIN EXPOSURE.

To ensure safety please adhere to the following:

1. Be sure to wear sun-glasses when servicing theprojector with the lampturned on and the topenclosure removed.

2. Do not operate the lamp outside of the lamp housing.

3. Do not operate for more than 2 hours with theenclosure removed.

UV-Radiation and Medium PressureLamp Precautions1. Be sure to disconnect the AC plug when replacing

the lamp.2. Allow one hour for the unit to cool down before

servicing.3 . Rep lace only w i th same type lamp. Type

CLMPF0042DE01 rated 75V/265W.4. The lamp emits small amounts of UV-Radiation, avoiddirect-eye contact.

5. The medium pressure lamp involves a risk ofexplosion. Be sure to follow installation instructionsdescribed below and handle the lamp with care.

Lamp Replacement

Note:Since the lamp reaches a very high temperature duringunits operation replacement of the lamp should bedone at least one hour after the power has been turnedoff. (to allow the lamp to cool off.)Installing the new lamp, make sure not to touch thelamp (bulb) replace the lamp by holding its reflector2.

[Use original replacement only.]

DANGER ! Never turn the power on withoutthe lamp to avoid electric-shock or damage of thedevices since the stabilizer generates high voltagesat its start.

CONTROLLING THE TOTAL OPERATING HOURS OF THE LAMP

The following control is carried out when the lamp has been used for 1900 hours and 2000hours.

1. After 1900-hour use

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 1,900-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 1,900-hour point. Now the lampLED indicator changes from green to red.

2. After 2000-hour use

When the power is turned on, "LAMP" appears in the on-screen display for about 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 thescreen for 5 minutes at the very 2000-hour point. Five minutes later, the power turns itself off and the unit isinterrupted. (The lamp LED indicator stays red since the 1900-hour point.)If you try to turn on the power three times after the 2000-hour point, the unit remains off.

3. When the 2000-hour point comes up, take the following steps.

Replace the lamp with new one. While holding down both the "VOL."" and "ADJ."" keys on the unit, turn on themain power switch (located on the side of the unit). The lamp operating hourmeter is now reset to zero. Turn onthe unit and make sure the time display shows "0000H".

4. Displaying the total operating hours of the lamp (used to check the total time)

Change the STATUS3 data settings: PICTURE at 0, BRIGHT at MAX, COLOR at MIN, TINT at MIN, andSHARPNESS at MAX. Hold down the SOUND DOWN and ENTER keys for longer than 3 seconds. By doingthis, the total operating hours will be displayed on the screen.

RESETTING THE LAMP OPERATING HOUR COUNTER

The unit is designed to keep its power off when the lamp has been used for 1900 and 2000hours. This is to protect the lamp fixture. Replace the lamp with new one and take the

following resetting procedure.

Resetting the lamp operating hour counter

1. Hold down the ENTER, ADJ." and ADJ.| buttons on the unit, and turn on the main power switch(located above the AC inlet).

2. Now the unit is turned on and the lamp operating hour counter is reset to zero. 000H appears on thescreen.

CONVERGENCE AND FOCUS ADJUSTMENT

Start the convergence and focus adjustments with the top cabinet and the signal shieldremoved but the power on. Use the remote control gun to adjust the image. Take thefollowing 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 panels with new ones. But until the focus has been completely readjusted, be careful not to

change the distance between the set and the screen, nor to move the projection lens focus and zoomrings.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 getout of the focus range, or a long-distance image (300 WIDE, for example) may come out of 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 turnthe 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 thedistance between the set and the screen, nor to move the projection lens focus and zoom rings.(If the distance has been changed or the projection lens readjusted, repeat the above steps 1 and 2.)

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

1. Right-and-left focus adjustment (Y direction) .Loosen the lock screws "b" and "c" and insert the eccentric screwdriver into the notch and hole "b". Turnthe screwdriver until the right and left halves on the screen get into focus.First get the right and left halves in balance. Then improve the accuracy while making the adjustment 2below.

2. Top-center-bottom focus adjustment (X and Z directions).Loosen the lock screws "a" and "c" and insert the eccentric screwdriver into the notch and hole "a" or "c".Turn the screwdriver until the top, center and bottom on the screen get into focus. In adjusting this top-to-bottom focus, temporarily tighten the lock screw "b" to fix the Y direction adjustment.

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

Note :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) Convergence adjustment The G-LCD panel has no convergence adjustment mechanism. Use this panel as convergence adjustment

reference.

Convergence and Focus Adjustments Mechanism

Note :

1 The eccentric cam is used for convergence adjustment. This means that the cams turning and the linearmovement are not always uniform.

2 This model is not equipped with the LCD image adjustment mechanism. This is because the dichroic prismis used for image formation. When the LCD panels all get into the best focus, the images are almost

completely converged.
