●The IC106 in the DIGITAL I/O UNIT (X88-2020-11) is not a replaceable component.
In case of defective of this IC, replace the entire unit (X88-2020-11).
●The IC5, IC21, and IC60 in the DVD unit (X37-1120-03) are not replaceable components.
In case of defective of any of these ICs, replace the DVD mechanism assembly. (The IC5 has a device key, which shall be
made consistent with the S/No. of the mechanism assembly after replacement. Thus you cannot replace only the board.)
In assembling the Traverse UD arm, Drive cam assembly,
Drive gear 5 and Drive gear 4C, align register marks on
these components.

Observe the instructions described in this document when
you are going to replace the parts or components that are
shown in this document.
1. Replacement of motor flat spring
• When mounting the flat spring that shall be in contact
with the worm gear, press the spring toward the direction
shown with an arrow so that there will be no gap between
the tip of the gear and the spring and then mount the
spring. The gear shall be pressure-inserted into the
motor.
• Note that there are two motors. Above operation of
mounting the flat spring is required on both of them.

2. Phase matching among gears
• Monitor tilt is driven under the control of the
rotary sensor and the phase matching among
gears and sensor is required.
The procedure for the phase matching is
described in the rest of this subsection.
1) Align the mark on the rack with the pin. (When
the monitor is folded down at 0 degree, the
rack is located at the position where the mark
and pin are aligned.
2) Insert the gear while keeping aligning the rack
pin with the notched section on the tilt gear 7.
3) Pre-assemble the tilt motor bracket assembly
(BKT Assy).
4) Align the notch on the sensor BKT with the
concave section of the sensor in the Assy.
5) While keeping the conditions stated in 3) and
4), insert the tilt motor BKT Assy transversally,
and fix the motor.

3. Insertion of slider
• This subsection describes cautions for inserting the
slider (slide section inside of the unit) into the outer
chassis.
1) On the rail at the left side of the slider, there is a part
called a stabilizer that is used to minimize play in right
and left sides.
The slide is made of resin. (Note that the rail is shown
at the right side of the slider in the picture.)
When inserting the slider, press the stabilizer towards
the direction shown with a blue arrow and insert it into
the groove on the rail.
2) PCB holder is pushed out towards the downside
of the picture due to the spring force and thus the
chassis and photo reflection sheet may be get caught
by the holder during the assembly.
Insert the slider while slightly lifting up the holder with
a pair of tweezers or any other similar device.
3) Insert the gear after confirming that the both of D
shaft gears at the right and left sides of the slider are
aliened with the tip of the right and left racks on the
chassis.
(Otherwise the slider will be inserted sidelong.
(Slider -Slide section inside of the unit)

PCB Holder
These portions
tend to be get
caught.
Hold and lift up the holder
with a pair of tweezers.
Push the opposite side of
the PCB holder towards
the downside of the picture
and lift up the portions
that may get caught.
