Repair Work Safety and Safety Checks
When performing any servicing, basic safety precautions should always
be followed, including the following:
(1) Be careful of high temperature sections.
Do not touch the lamp immediately after it has been used. It will be extremely hot.
(2) Observe cautions.
Some parts require careful handling at the time of servicing.
Cautions about these parts are indicated in the labels or by marking on the cabinet, chassis,
or parts. Be sure to observe these cautions and cautions in the Instruction Manual.
(3) Be careful of electrical shock.
When the power is turned on and maintenance service is performed with the cover
removed, be sure to wear a pair of gloves. Be sure to disconnect the plug when replacing
parts.
(4) Use specified parts only.
Parts used in this product are selected from safety point of view, such as of inflammable or
voltage resistant characteristics. Therefore, use only specified parts for replacement.
(5) Put parts and wirings back after servicing.
Some parts make use of insulation materials such as tubing and tape for the sake of safety.
Some other parts are mounted in a floated state from the PCB.
In addition, internal wiring is laid properly by clamp or the like to avoid contact with
heating parts and high-voltage parts.
Be sure to put them back as before.
(6) Perform safety check after servicing.
Check that screws, parts, and wiring removed for servicing are put back in position.
Check that other components have not been damaged during servicing.
Check insulation between an external metallic sections and the blade of the plug before the
power is turned on.
-ii-
How to perform insulation check
Unplug the equipment from the outlet and disconnect all the wires and cables connected to
the equipment. Then, check that the insulation resistance between each plug and the
externally exposed metallic sections (Note) of respective terminals is 10 MΩ or larger, using
a 500V insulation resistance meter.
Note) Externally exposed metallic sections: VIDEO input terminal, S-VIDEO input

3. Function Descriptions of Replacement Parts
3.1 Replacement Parts
For the numbers in the parentheses at the left of part names, refer to the description given in
the same Item No. in “3.2 List of Replacement Parts”.
3.1.1 First Category Replacement Parts
(101) ASC-02PKG
The ASC-02PKG has Video input/output
terminals, Audio input/output terminals, and RS232C input terminals and outputs a video input
signal to the ASM-02PKG. This board generates
voltages used by the ASM-02PKG.
(102) ASM-02PKG
The ASM-02PKG has a main CPU on it and
controls the whole unit. This board processes all
the video signals and outputs them to ASO02PKG.
(103) ASO-02PKG
The ASO-02PKG is an interface between
components in the unit. This board processes all
the video signals and outputs them to the Optical
Engine. This board has a sub-CPU on it and
controls the unit during the Standby mode.
-4-
(104) Main Power Supply (MPF1615)
This is a main power supply of the LPX100
projector and supplies electric power to
components of the unit.
(105) Lamp Power Supply (PHG151G10)
Power Supply to turn on the projection lamp.

colors. And verify that the vertical lines are not tinted in the all white crosshatch
pattern.
• Next, in the gray-scale pattern, adjust CLDLY to minimize the faint vertical stripes.
• Display a gray-scale pattern of each of R, G, and B in one color, and then adjust the
color with LCD2(Adjust GA4)CK-PHASE to minimize the vertical stripes on the
projected image.
Be aware that a ghost image may be formed depending on the adjustment value.
• Display a gray-scale pattern of each of R, G, and B in one color, and verify that
there are no faint vertical stripes on the projected image.
If vertical stripes are observed, adjust the colors with LCD1(CXA/6050)NRS so
that no stripes will appear.
