UV-RADIATION PRECAUTION

The light source, metal halide lamp, in the LCD projector emits small amounts of UV-Radiation.

A VOID DIRECT EYE AND SKIN EXPOSURE.

To ensure safety please adhere to the following:

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 CLMPF0042DE01 rated 75V/265W.

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.

Lamp 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.) Installing the new lamp, make sure not to touch the lamp (bulb) replace the lamp by holding its reflector

2. [Use original replacement only.]

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

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 lamp LED 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 of f 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 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 the main power switch (located on the side of the unit). The lamp operating hourmeter is now reset to zero. T urn on the 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, and SHARPNESS at MAX. Hold down the SOUND DOWN and ENTER keys for longer than 3 seconds. By doing this, 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 2000 hours. 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 the

screen.

Hold down the “ADJ.|”, “ADJ."” and “ENTER” keys at once.

CONVERGENCE AND FOCUS ADJUSTMENT

» Start the convergence and focus adjustments with the top cabinet and the signal shield

removed but the power on. Use the remote control gun 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 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 zoom rings. 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 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 distance 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 (θY direction) . Loosen the lock screws "b" and "c" and insert the eccentric screwdriver into the notch and hole "b". Turn the 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 2

(

below.

2. Top-center-bottom focus adjustment (θX 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-tobottom focus, temporarily tighten the lock screw "b" to fix the θY 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.

3. B-LCD panel adjustment (the same for the R-LCD panel)

(A) Focus adjustment

» T ake the same procedure as for the G-LCD panel focus adjustment. Note that the adjustment range is small

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.

(B) Convergence adjustment

» Use a crosshatch pattern signal for this adjustment.

Make the adjustment just for the G-colour and the relevant colour. (1) Loosen the convergence lock screw "d". (2) With the G-LCD panel’s screen center as reference, adjust the B-LCD panel in the X, Y and θZ directions. (3) Finally tighten up the convergence lock screw "d".

)

XV-Z1E/A

Note :

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 dichroic prism

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

Replacing the LCDs

With the top cabinet removed

(1)Remove the output shield. (2)Disconnect the LCD flat cable from the output PWB connector. (3)Remove the lock screws "b" and "c". Detach the R/B adjusting plate or the G adjusting plate together with the LCD

panel. (4)Separate the LCD panel from the adjusting plate. (5)Mount a new LCD panel in the reverse order of the above steps (1), (2), (3) and (4).

~ Readjust the convergence and focus. Note that the G LCD panel needs no convergence adjustment and has

a small adjustment range in the Z direction.
