(J21-9716-03)

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 fl at 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 fl at 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 de-

scribed in the rest of this subsection.

Tilt drive gear train

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.

T-Rack-A Pin

Location of mark
on the Rack

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 fi x 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 refl ection 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.

(Slider -Slide section inside of the unit)

Stabilizer

PCB Holder

Hold and lift up the holder
with a pair of tweezers.

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.

4

These portions
tend to be get
caught.

Push the opposite side of
the PCB holder towards
the downside of the picture
and lift up the portions
that may get caught.

ADJUSTMENT

1. Flicker adjustment

Condition

●

Video source: VIDEO

Video: RAMP

BRIGHT: MAX

MODE: FULL

Adjustment procedure

●

Display RAMP.

q

Rotate VR200: X35-496 until the leading edge of black

w

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.

2. VCOM Amplitude and AGC and WB

Automatic adjustments

Adjustment Method

●

Input 100% (white) in AV-IN.

q

Press Auto Adjust on the Test Mode Main screen.

w

Press Auto Adjust Start.

e

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.

16

After the automatic adjustment, “Auto Set OK” will be

r

shown to indicate the completion of the adjustment.

∗ 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 confi rm that the stick is exactly

on the center of the “+” mark while keeping touching the
