1. When the color wheel unit has been replaced
2. When the color wheel sensor has been replaced
3. When the optical drive unit has been replaced (if a deviation from normal setting is found)
4. When the F/E PWB has been replaced (if a deviation from normal setting is found)

●

1. Personal computer (run on Windows 95/98)
2. RGB cable
3. Dedicated application program (white.exe program commonly used for both models UP and U2)
4. Wrench (5 mm)
5. Projection screen (normally white)

Note:  During the adjustment, be careful not to touch the lamp and other hot components.

●

 Procedure

1. Adjustment should be done with the top cover and

the front panel removed.

2. Connect the projector to the PC (RGB mode).
3. Start up the dedicated application program

(white.exe) on the PC.

4. Press the "6" key on the keyboard.  After the pattern

shown in Fig. 1 at right has appeared, press the
"R" key to get the red image displayed for checking.
Check the other colors as well (*1).

5. When part of the image does not appear in red,

loosen the wheel screw shown in Fig. 2 below and
slide the wheel sensor up or down.  Fix the wheel
sensor again at the position where the color
deviation disappears.

6. Finally press the "Q" key on the keyboard to finish

the program.

●

1:The basic black and white patterns are registered in the numeric keys 0 thru 9 on the keyboard.  The colors can be

changed to any of White(W), Black(K), Red(R), Green(G), Blue(B), Magenta(M) and Cyanic(C).

1. Personal computer (run on Windows 95/98)
2. Projection screen (normally white)
3. Light distribution point display program (Lumens.exe program commonly used for both models UP and U2)
4. Illumination meter

●

 Measuring lumen value

Connect the projector to the PC, and starts lighting.
Start up the light distribution point display program
(Lumens.exe) on the PC.  Make the room dark.  (A
darkroom is recommended.)  Measure the illuminance
at the nine points shown at right.  Put the measured
illuminance into the following equation to obtain the
lumen value.

Lumen value (L)

= (Average illuminance of 9 points) x (Projected area in m

2

)

={(P1+P2+ • • • +P9) / 9} x (A xB)

● 

Put the measured illuminance into the following equation to obtain the evenness of illuminance.

Evenness of illuminance (%) = (The lowest illuminance measured out of 9 points) / (Average illuminance of 9 points)

= [MIN.(P1~P9) / {(P1+P2+ • • • +P9) / 9}] x 100

● 

Put the measured illuminance into the following equation to obtain the peripheral illuminance ratio.

Peripheral illuminance ratio (%) = (Average illuminance at P1, P3, P7 and P9) / (Illuminance at P5)

= {(P1+P3+P7+P9) / 4} / P5] x 100

The factory settings are as follows.

Model PG-M10X

Lumen value: Min. 500 Lm

Evenness of illuminance: Min. 50%

Peripheral illuminance ratio: Min. 80%

Model PG-M10S

Lumen value: Min. 500 Lm

Evenness of illuminance: Min. 50%

Peripheral illuminance ratio: Min. 80%

Color wheel
Once disassembled, this part may
need readjustment.

DMD assembly
This assembly can be disassembled. But be care-
ful not to allow dust and fingerprint on it. Otherwise
the images may be adversely affected.

Condenser lens ass'y

Spherical
mirror

Cylinder mirror

Do not separate the spherical
mirror and cylinder mirror from
the lens base (46).

If the condenser lens or mirror has not
been correctly adjusted, there will be
shades on the projection screen.
(Usually shades appear on the right-
hand edge or at the bottom right cor-
ner of the screen.)

The lamp housing has a built-in thermostat which puts out the lamp when the temperature becomes 110°C.
Similarly, the power supply unit and lamp driver have thermostats which terminate power supply and driver operation
when the temperature reaches 120°C and 115°C, respectively.

The lamp will not light up unless the lamp cover is mounted.

When the lamp fails to light up, the status LED indicator starts flickering.  Different flickering intervals help identify
the cause.  (Refer to the figure at right and the table below.)

OFF (kept off)

ON (kept on)

Flickers with a cycle of one
second (0.5 sec. ON and
0.5 sec. OFF)

Flickers with a cycle of 4
seconds (2 sec. ON and 2
sec. OFF)

Flickers with a cycle of 8
seconds (4 sec. ON and 4
sec. OFF)

Flickers with a cycle of 12
seconds (6 sec. ON and
6sec. OFF)

Normal condition

Total lamp timer has exceeded
1000 hours.

Lamp cover is not mounted cor-
rectly.

Temperature protector is acti-
vated.

Temperature protector still acti-
vated. Power may fail to come
on if the main power switch is
turned on just after it has turned
off.

Lamp light-up voltage error de-
tector is activated.

Fan is nor running.

Lamp fails to light up.

Replace the lamp with new one, and reset the
total lamp timer.

Mount the lamp cover correctly.

If room temperature is too high, relocate the pro-
jector to cooler area.  If the projector's internal
temperature rises abnormally, check the cool-
ing fan vent hole and the unit's bottom vent hole.
Clean them if they are clogged.

Wait for one minute, and try again to turn on the
power switch.

Wait for one minute, and try again to turn on the
power switch.

Check the fan.

Wait for one minute or longer, and try again to
turn on the power switch.  Make internal check
if the condition is not improved.
