4-8 Color uniformity adjustment
Preparations
1.
Perform these adjustments after the white balance
adjustment described in Section 4-7.
2. Make a color uniformity adjustment for the follow-
ing four tones.
MIN tone (approx. 4% input signal)
MID-L tone (approx. 14% input signal)
MID-H tone (approx. 25% input signal)
MAX tone (approx. 57% input signal)
3. Place the cursor on [C.UNIF.] in the FACTORY
MENU and press the [ ] key. This displays the
Adjust Tone menu at the bottom of the screen.
To choose the tone to be adjusted, press the [ ]
key and then use the [ ] or [ ] key.
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.
To temporarily turn correction off, place the
6.
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 transmitter
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 adjust-
ment.
When 4 tones and all colors are to be reset,
place the cursor on [C.UNIF.] in the FACTORY
MENU, press the [RESET] key and select
[DEFAULT].
When only 1 tone is to be reset, place the
cursor on the tone to be reset, press the

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
transmitter 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
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 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].)

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 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 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],
8.
[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.

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
Mounting (chips) on mounted PCB 320˚C±30˚C
Mounting (chips) on empty PCB 380˚C±30˚C
Chassis, metallic shield, etc. 420˚C±30˚C

6-7 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 in 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.
• 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.
HIGH VOLTAGE HIGH TEMPERATURE HIGH PRESSURE
• 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. In addi­tion, working in high places is dangerous.
• 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.
• Handle with care: jolting or scratching could cause the lamp bulb to burst during use.
• If the indicators or a message prompts you to replace the lamp (see the section “Related Messages” and “Regarding the indicator Lamps”), replace the lamp as soon as possible. Using the lamp for long periods of time, or past the replacement date, could cause it to burst. Do not use old (used) lamps; this is a cause of breakage.

6-9 Notice of AUTO adjustment
Use of AUTO adjustment with the image through RGB input optimizes V_POSI, H_POSI, H_SIZE and
H_PHASE automatically.
In case that projected image has dark tone around its peripheral, AUTO operation sometimes makes artifacts
in the image, shifts capture area and so on. Those failures are caused by period of image data is not exactly
distinguished to period of blanking on signal processing.
To avoid such phenomena, AUTO function should be used with the full size picture that has bright tone on its
peripheral.
Image when AUTO operates correctly
Note
1) The phenomenon at the failure of AUTO adjustment depends on resolution of input source, scene of pic-
ture etc.
2) There is no failure above in AUTO with video source through VIDEO, S-VIDEO or COMPONENT input. The
reason is why recognition of input signal’s standard does not need to search the capture range from input
signal itself.

(1) Send the request code Header + Command data (‘02H’+‘00H’+ type (2 bytes)+ ‘00H’+‘00H’) from the
computer to the projector.
(2) The projector returns the response code ‘1DH’+ data (2 bytes) to the computer.
Changing the projector settings (Set command)
(1) Send the setting code Header + Command data (‘01H’+‘00H’+ type (2 bytes) + setting code (2 bytes))
from the computer to the projector.
(2) The projector changes the setting based on the above setting code.
(3) The projector returns the response code ‘06H’ to the computer.
Using the projector default settings (Reset Command)
(1) The computer sends the default setting code Header + Command data (‘06H’+ ‘00H’+ type (2 bytes) +
‘00H’+‘00H’) to the projector.
(2) The projector changes the specified setting to the default value.
(3) The projector returns the response code ‘06H’ to the computer.
Increasing the projector setting value (Increment command)
(1) The computer sends the increment code Header + Command data (‘04H’+ ‘00H’+ type (2 bytes) +‘00H’+
‘00H’) to the projector.
(2) The projector in creases the setting value on the above setting code.
(3) The projector returns the response code ‘06H’ to the computer.
Decreasing the projector setting value (Decrement command)
(1) The computer sends the decrement code Header + Command data (‘05H’+ ‘00H’+ type (2 bytes) +‘00H’ +
‘00H’) to the projector.
(2) The projector decreases the setting value on the above setting code.
(3) The projector returns the response code ‘06H’ to the computer.
When the projector cannot understand the received command
When the projector cannot understand the received command, the error code ‘15H’ is sent back to the com-
puter.
Sometimes the projector cannot properly receive the command. In such a case, the command is not exe-
cuted and the error code ‘15H’ is sent back to the computer. If this error code is returned, send the same
command again.
When the projector cannot execute the received command.
When the projector cannot execute the received command, the error code ‘1cH’ + ‘xxxxH’ is sent back to the
computer. When the data length is greater than indicated by the data length code, the projector ignore the
excess data code.
Conversely when the data length is shorter than indicated by the data length code, an error code will be
returned to the computer.
NOTE • Operation cannot be guaranteed when the projector receives an undefi ned command or data.
• Provide an interval of at least 40ms between the response code and any other code. The projector outputs test data when the power supply is switched ON, and when the lamp is lit. Ignore this data.
• Commands are not accepted during warm-up.
