The IC3, and IC11 in the DVD unit (X37-1100-03) are not replaceable components.
When these ICs are defective, replace the whole DVD mechanism assembly (X92-6160-00).
You cannot replace only the board.
TEST MODE is the same as DDX512.
Please refer to the service manual (DDX512: B53-0620-00).

CAUTIONS IN ASSEMBLING PANEL DRIVE MECHANISM (A10-5171)
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 be-
tween 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.

Mount the flat spring
while pressing it
towards the direction
shown with an arrow
so that there will be no
clearance.

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 de-
scribed 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 chas-
sis 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.

1. Flicker adjustment
●Condition
Video source: VIDEO
Video: RAMP
BRIGHT: MAX
MODE: FULL
●Adjustment procedure
qDisplay RAMP.
wRotate VR200: X35-496 until the leading edge of black
area reaches far right of the screen. As shown in the
next picture, the edge is now located at about 1/5 of the
screen width from the left of the screen. (At the comple-
tion of this adjustment, most of the screen will be in
black.)
The position where the adjustment is best completed
can be shown darkest and clearest.
Adjust it by confirming this area
Example: Keep rotating the VR200 so that the black area
is gradually expanded (to the right), and if you rotate the
VR200 too much, the black area will start shrinking. So
when you see the black area starts shrinking, rotate the
VR200 backward a bit to make the adjustment relatively
stable.
2. VCOM Amplitude and AGC and WB

●Adjustment Method
qInput 100% (white) in AV-IN.
wPress Auto Adjust on the Test Mode Main screen.
ePress Auto Adjust Start.

∗If the center of “+” mark wasn’t pressed accurately, press
Cancel to start over the adjustment.
Note
The touch panel adjustment data is finalized when the
touch stick is released from the mark.
Therefore, the Knack for Adjustment is not to release the
touch stick from the mark right after touching the center
of the “+” mark, but to confirm that the stick is exactly
on the center of the “+” mark while keeping touching the
screen. (If the stick is not exactly on the center of the
mark, move the stick onto the center of the mark while
keeping touching the screen.)
Then, quickly and vertically release the stick from the
screen.
