Preparations

1.

Perform these adjustments after the adjustments

described in the section 4-6.

2. Make a color uniformity adjustments for the

following tones.

MIN tone (approx. 7% input signal)

MID-1 tone (approx. 14% input signal)

MID-2 tone (approx. 21% input signal)

MID-3 tone (approx. 29% input signal)

MID-4 tone (approx. 36% input signal)

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.

To temporarily turn correction off, place the

cursor on [C.UNIF.] in the Adjust Tone menu and

press the [ ] key. The ON/OFF menu appears.

Place the cursor on [ON] with the [ ] key and

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

cursor on [OFF] and press the [ ] key.

7. Although this adjustment can also be made

using internal signals, we will here use the

[ENTER] key on the remote control to select the

following two signals.

Solid monochrome adjustment color (use G

color adjustment when a color differential

meter is used).

Solid white (use for adjustment other than

above).

8. Reset color-shading correction before

adjustment.

When resetting all values of 8 tones and all

colors, place the cursor on [C.UNIF.] in the

FACTORY MENU, press the [RESET] key and

select RESET in the dialog.

When resetting only 1 tone, place the cursor

on the tone such as MID-1 to be reset, press

the [RESET] key and select RESET in the

dialog.

Adjustment procedure 1

(When a color differential meter is used)

1. First adjust the [MID-1] 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

switch 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 points have the

average of Y2 and Y3.

Y2 = ( Y2 + Y3 ) / 2 ± 2 [%]

Y3 = ( Y2 + Y3 ) / 2 ± 2 [%]

5. No.10 and No.11 adjustment points have the

average of Y10 and Y11.

Y10 = ( Y10 + Y11 ) / 2 ± 2 [%]

Y11 = ( Y10 + Y11 ) / 2 ± 2 [%]

6. Then adjust the [MID-1] tone [R] and [B].

When the background is [G] monochrome,

press the [ENTER] key on the remote control to

switch 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 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

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

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

[MID-1].

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 the [MIN] tone [G] so that the

adjustment values are two times as much as

MID-1] tone [G] values.

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

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-2] tone.

(Adjust [MID-2] tone [G] so that the adjustment

data set half as many as [MID-1] tone [G].)

16. Now make similar adjustments for [MID-3],

[MID-5], [MAX] tones. (It is not necessary to

adjust the [G] data in these tones.)

17. After completing the step 16, set the value of

the [MID-4] tone [R]: [No.2] to the mean of the

values of the [R]: [No.2] in the [MID-3] and

[MID-4] tones.

18. Set all the values for the [No.2] to [No.17] of

the [MID-4] tone [R] and [B] in the same way as

the step 17.

19. Finally, set the data of the [MID-6] tone [R] and

[B] using the values of the [MID-5] and [MAX]

tones in the same way as the [MID-4] tone [R]

and [B] adjustments in the step 17 and 18.

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

If the background is [G] monochrome, press the

[ENTER] key on the remote control to switch 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] 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.

8.

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 adjustments for other tones,

except the [MID-4] and [MID-6] tones, as

described in steps 1 to 8 above.

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.

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

Mounting (chips) on mounted PCB 320˚C±30˚C

Mounting (chips) on empty PCB 380˚C±30˚C

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 life-

time, 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

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.

• 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.

• Before replacing the lamp, turn the projector off and unplug the power cord, then wait at least
45 minutes for the lamp to cool suffi ciently. Handling the lamp while hot can cause burns, as
well as damaging the lamp.

• Never unscrew except the appointed (marked by an arrow) screws.

• Do not open the lamp cover while the projector is suspended from above. This is dangerous,
since if the lamp’s bulb has broken, the shards will fall out when the cover is opened.

• Do not use the projector with the lamp cover removed. At the lamp replacing, make sure that
the screws are screwed in fi rmly. Loose screws could result in damage or injury.

• Use only the lamp of the specifi ed type.

• If the lamp breaks soon after the fi rst time it is used, it is possible that there are electrical

problems elsewhere besides the lamp. If this happens, contact your local dealer or a service
representative.

• Handle with care: jolting or scratching could cause the lamp bulb to burst during use.

• Using the lamp for long periods of time could cause it dark, not to light up or to burst. When
the pictures appear dark, or when the color tone is poor, please replace the lamp as soon as
possible. Do not use old (used) lamps; this is a cause of breakage.
