KVT-819DVD/829DVD /829DVDY/839DVD
The IC106 in the DIGITAL I/O UNIT (X88-2020-14) is not a replaceable component.
In case of defective of this IC, replace the entire unit (X88-2020-14).
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.)
MICROCOMPUTER’S TERMINAL DESCRIPTION, TEST MODE, ADJUSTMENT are the same as KVT-719DVD.
Please refer to the service manual (KVT-719DVD: B53-0507-00).

GEAR POSITION IN A DVD MECHANISM

In assembling the Traverse UD arm, Drive cam assembly,
Drive gear 5 and Drive gear 4C, align register marks on
these components.
Inscriptions (register marks) on gears Align 6 marks as shown in the figure
Traverse UD arm
Drive cam assembly
Drive gear 5 Do not forcibly press gears to engage their teeth but freely let the gears fall under their own weight and engage their teeth.

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 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 fl at spring is required on both of them.
Tilt drive gear train

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

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.
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
chassis 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.
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.
