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 [ENTER] key on the remote control to

change to solid [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 aver-

age of Y2 and Y3.

Y2 = ( Y2 + Y3 ) / 2 ± 2 [%]

Y3 = ( Y2 + Y3 ) / 2 ± 2 [%]

5. No.10 and No.11 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 [ENTER] key on the remote control 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 differ-

ence meter is used, the [∆](delta) mode

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 measure-

ment shown after this displays the devia-

tion 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

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

[No.17] and adjust their color coordinates start-

ing in order from the small number points.

This completes adjustments required for [MIN].

Note: Since excessive correction may lead to a

correction data overview during 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 adjust-

ment data set two 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 [ENTER] 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. Now measure the color coordinates of mea-

surement 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 start-

ing 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].)

CP-S245(CC9SMN)/CP-X255/ED-X8255(CC9XMN)/PJ656(CC9XM)

Adjustment procedure 2

(visual inspection)

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

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

If the background is [G] monochrome, press the

[ENTER] key on the remote control 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 inten-

sity 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] and [No.11]. Adjust the [R] and [B] of

each 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

No. 6 deviation range No. 7 deviation range No. 8 deviation range No. 9 deviation range

No. 14 deviation range No. 15 deviation range No. 16 deviation range No. 17 deviation range

6. Service points

6-1 Lead free solder [CAUTION]

This product uses lead free solder (unleaded) to help preserve the environment. Please read these

instructions before attempting any soldering work.

CAUTION

Always wear safety glasses to prevent fumes or molten solder from getting into the eyes. Lead free solder

can splatter at high temperatures (600˚C).

Lead free solder indicator

Printed circuit boards using lead free solder are engraved with an "F" or "LF".

Properties of lead free solder

The melting point of lead free solder is 40-50˚C higher than leaded solder.

Servicing solder

Solder with an alloy composition of Sn-3.0Ag-0.5Cu or Sn-0.7Cu is recommended.

Although servicing with leaded solder is possible, there are a few precautions that have to be taken. (Not

taking these precautions may cause the solder to not harden properly, and lead to consequent malfunctions.)

Precautions when using leaded solder

Remove all lead free solder from soldered joints when replacing components.

If leaded solder should be added to existing lead free joints, mix in the leaded solder thoroughly after the

lead free solder has been completely melted (do not apply the soldering iron without solder).

Servicing soldering iron

A soldering iron with a temperature setting capability (temperature control function) is recommended.

The melting point of lead free solder is higher than leaded solder. Use a soldering iron that maintains a high

stable temperature (large heat capacity), and that allows temperature adjustment according to the part being

serviced, to avoid poor servicing performance.

Recommended soldering iron:

Soldering iron with temperature control function (temperature range: 320-450˚C)

Recommended temperature range per part:

Part Soldering iron temperature

6-6 Lamp

WARNING

●

The projector uses a high-pressure mercury glass lamp. The lamp can break with a loud bang, or burn

out, if jolted or scratched, handled while hot, or worn over time. Note that each lamp has a different lifetime, and some may burst or burn out soon after you start using them. In addition, when the bulb bursts, it is possible for shards of glass to fly into the lamp housing, and for gas containing mercury to escape from the projector’s vent holes.

●

About disposal of a lamp • This product contains a mercury lamp; do not put it in the trash. Dispose of

in accord with environmental laws. For lamp recycling, go to www.lamprecycle.org. (in the US) For product disposal, contact your local government agency or www.eiae.org (in the US) or www.epsc.ca (in Canada).

• If the lamp should break (it will make a loud bang when it does), unplug the power cord from the outlet. Note that shards of glass could damage the projector’s internals, or cause injury during handling.

Disconnect

the plug

from the

power

outlet

• If the lamp should break (it will make a loud bang when it does), ventilate the room well, and make sure not to breathe the gas that comes out of the projector vents, or get it in your eyes or mouth.
