SERVICE MANUAL

Caution

Be sure to read this manual before servicing. To assure safety from re, electric shock, injury, harmful

radiation and materials, various measures are provided in this HITACHI Multimedia LCD Projector. Be sure to

read cautionary items described in the manual to maintain safety before servicing.

Service Warning

(C7X)

1. When replace the lamp, to avoid burns to your ngers. The lamp becomes too hot.

2. Never touch the lamp bulb with a nger or anything else. Never drop it or give it a shock. They may cause

bursting of the bulb.

3. This projector is provided with a high voltage circuit for the lamp. Do not touch the electric parts of power

unit (main), when turn on the projector.

4. Do not touch the exhaust fan, during operation.

5. The LCD module assembly is likely to be damaged. If replacing to the LCD module assembly, do not hold

the FPC of the LCD module assembly.

6. Use the cables which are included with the projector or specied.

Adjustment procedure

1. First, adjust the G color.

2. Select GAMMA, SUB-CONTRAST, and G: in the

Adjust menu. If the background is white solid,

press the [MENU SELECT] key on the Remote

control transmitter to change to [G] monochrome in

the 28-tone grayscale.

3. Adjust GAMMA, SUB-CONTRAST, and G: in the

Adjust menu so that brightness of 28 steps is best.

4. Don’t adjust GAMMA, SUB-BRIGHT, and G: in the

Adjust menu. Because we want to keep the best

contrast ratio.

5. Then adjust colors R and B.

the 28-tone grayscale.

7. Adjust GAMMA, SUB-BRIGHT, R: and B: in the

Adjust menu so that low-brigtness white balance is

best.

8. Adjust GAMMA, SUB-CONTRAST, R: and B: in the

Preparations

1. Perform these adjustments after the white balance

adjustment described in Section 4-5.

2. Make a col o r uniformi t y adjustm e n t fo r the

following four tones.

MIN tone (approx. 10% input signal)

MID-L tone (approx. 21% input signal)

MID-H tone (approx. 50% input signal)

MAX tone (approx. 75% input signal)

3. Place the cursor on the tone to be adjusted in the

Adjust menu and press the [ ] key. This displays

the Adjust Tone menu at the bottom of the screen.

Select the major adjustment lattice point No. and

color, and then adjust them.

4. The major adjustment lattice point numbers (a total

of 17 points) corresponds to the major adjustment

lattice point positions in the diagram on the right.

The color uniformity of the entire screen can be

adjusted by adjusting the white balance for each of

the points starting in order from the low numbers.

5. Adjustment point No.1 should not be adjusted,

because it controls the brightness of the entire

screen.

6. To temporarily turn correction off, place the cursor

on “ON” in the Adjust Tone menu and press the

[ ] key. To turn it on again, place the cursor on

OFF in the Adjust Tone menu and press the [ ]

key.

7. Although this adjustment can also be made using

interna l signals, we will here use the [MENU

SELECT] key on the Remote control transmitter to

select the following two signals.

Solid monochrome adjustment color (use G color

adjustment when a color differential meter is

used).

Soli d white (use for adj ustment oth er than

above).

8. Reset color-shading correction before adjustment.

When 4 tones and all colors are to be reset,

place the cursor on [C.UNIF.] in the Adjustment

menu, pr e s s the [RESET] key and se l ect

[DEFAULT].

When only 1 tone is to be reset, place the cursor

on the tone to be reset, press the [RESET] key

and select [DEFAULT].

Single tone and monochrome resets cannot be

performed.

Major adjustment lattice point position

Adjustment procedure 1

(when a color differential meter is used)

1. First adjust [MID-L] tone [G:].

2. Select adjustment point [No.2][G:].

When the background is not [G] monochrome,

press the [MENU SELECT] key on the Remote

con t rol t ra ns mitt e r to c hang e to s ol id [ G ]

monochrome.

3. Measure the illumination at adjustment points No.

2, No.3, No.10 and No.11.

The values should be:

No.2 = Y2 [lx] No.10 = Y10 [lx]

No.3 = Y3 [lx] No.11 = Y11 [lx]

4. No.2 and No.3 adjustment point have the average

of Y2 and Y3.

Y2 = ( Y2 + Y3 ) / 2 ± 2 [%]

Y3 = ( Y2 + Y3 ) / 2 ± 2 [%]

5. No.10 and No.1 1 adjustment point have the

average of Y10 and Y11.

Y10 = ( Y10 + Y11 ) / 2 ± 2 [%]

Y11 = ( Y10 + Y11 ) / 2 ± 2 [%]

6. Then adjust [MID-L] tone [R] and [B].

When the background is [G] monochrome, press

the [MENU SELECT] key on the Remote control

transmitter to change to solid white.

7. Measure the color coordinates of adjustment point

[No.1] and make a note of them.

Assume that they are x = x1, y = y1.

Note: When the CL-100 color and color difference

meter is us e d , the [ ](delta ) mo d e is

convenient. When adjustment point [No.1]

color coordinate has been selected, set the

slide switch on the side to [ ](delta) while

holding down the [F] button on the front

panel. The measurement shown after this

displays the deviation from measurement

point 1.

8. Measure the color coordinates of measurement

point [No.2] and adjust [No.2][R:] and [B:] so that

the coordinates are as follows.

x = x1 ± 0.005 , y = y1 ± 0.010

CP-X430W

9. Similarly, measure adjustment points [No.3] to

[No.17] and adjust their color coordinates starting

in order from the small number points.

This completes adjustments required for [MIN].

Note: Since excessive correction may lead to a

correction data overview dur ing internal

calculations, use the following values for

reference.

[No.2] to [No.5] ± 40 or less

[No.6] to [No.9] ± 50 or less

[No.10] to [No.13] ± 70 or less

[No.14] to [No.17] ± 120 or less

10. Then adjust [MIN] tone [G] so that the adjustment

data set three times as much as [MID-L] tone [G].

This completes [G] color adjustments.

11. Then adjust [MIN] tone [R] and [B].

Select [No.2] [B:] and press the [MENU SELECT]

key on the Remote control transmitter to change to

solid white.

12. Measure the color coordinates of adjustment point

[No.1] and make a note of them.

Assume that they are x = x1, y = y1.

13. N o w m ea s u r e th e c ol or co o r di na te s o f

measurement point [No.2] and adjust [No.2][R:]

and [B:] so that the coordinates are as follows.

x = x1 ± 0.005 , y = y1 ± 0.010 (Target)

x = x1 ± 0.020 , y = y1 ± 0.040

14. Similarly, measure adjustment points [No.3] to

[No.17] and adjust their color coordinates starting

in order from the small number points.

This completes [MIN] tone adjustments.

15. Now make similar adjustments for [MID-H] tone.

(Adjust [MID-H] tone [G] so that the adjustment

data set half as many as [MID-L] tone [G].)

16. Now make similar adjustments for [MAX] tone.

(Adjust [MAX] tone [G] so that the adjustment data

set half as many as [MID-L] tone [G].)

Adjustment procedure 2

(visual inspection)

1. First adjust [MIN] tone [G:].

2. Select [No.2] [G:].

If the background is [G] monochrome, press the

[MENU SEL ECT] key on the Rem ote con trol

transmitter to change to solid white.

3. View measurement point [No.2] and [No.3].

Lower the [G] color intensity only of the color point

whose [G] color is more intense than measurement

point [No.1].

4. View measurement point [No.10] and [No.11].

Lower the [G] color intensity only of the color point

whose [G] color is more intense than measurement

point [No.1], and raise the intensity of the point

whose color intensity is lower than measurement

point [No.1].

5. Now adjust the [MIN] tone for colors [R] and [B].

6. View measurement points [No.2], [No.3], [No.10]

an d [No.1 1 ] . Adjust the [ R ] and [ B ] of e ach

measurement point so that they have the same

color as measurement point [No.1].

Adjustment technique:

First, adjust [B:] of the point whose color is to be

adjusted so that it approximates that of [No.1]. If

[R:] is low at this time, the image will have cyan

cast, in which case [R:] is increased. On the other

hand, if [R:] is excessive, the image will have a

magenta cast, in which case [R:] is decreased.

Overall, a cyan cast makes it easy to see color shading.

7. Next, view measurement points [No.4], [No.5],

[No.12], [No.13] and make similar adjustments.

Then adjust measurement points [No.6], [No.7], [No.8],

[No.9], [No.14], [No.15], [No.16] and [No.17].

This completes the [MIN] tone adjustments.

9. Make similar another three tones as described in

steps 1 to 8 above.

No. 2 deviation range No. 10 deviation range No. 3 deviation range No. 11 deviation range

No. 4 deviation range No. 12 deviation range No. 5 deviation range No. 13 deviation range
