1.1 Safety Precautions

SECTION 1
PRECAUTIONS
!
!
Burrs formed during molding may be left over on some parts of the chassis. Therefore, pay attention to such burrs in the case of preforming repair of this system.
Please use enough caution not to see the beam directly or touch it in case of an adjustment or operation check.
(No.MA165)1-5
Page 6

1.2 Preventing static electricity

Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs.
1.2.1 Grounding to prevent damage by static electricity
Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as CD players. Be careful to use proper grounding in the area where repairs are being performed.
(1) Ground the workbench
Ground the workbench by laying conductive material (such as a conductive sheet) or an iron plate over it before placing the traverse unit (optical pickup) on it.
(2) Ground yourself
Use an anti-static wrist strap to release any static electricity built up in your body.
(caption) Anti-static wrist strap
1M
Conductive material (conductive sheet) or iron plate
(3) Handling the optical pickup
• In order to maintain quality during transport and before installation, both sides of the laser diode on the replacement optical pickup are shorted. After replacement, return the shorted parts to their original condition. (Refer to the text.)
• Do not use a tester to check the condition of the laser diode in the optical pickup. The tester's internal power source can easily destroy the laser diode.

1.3 Handling the traverse unit (optical pickup)

(1) Before disconnecting the flexible wire from the connector CN101
on the flexible wire.
Caution:
If you do not follow this instruction, the DVD pickup may be damaged.
(2) Disconnect the flexible wire from the connector CN101 (3) Remove the solders from the short-circuit points on the flexible wire after replacing the DVD pickup. (4) Connect the flexible wire to the connector CN101

1.4 Important for laser products

!
1.CLASS 1 LASER PRODUCT
2.DANGER : Invisible laser radiation when open and inter
lock failed or defeated. Avoid direct exposure to beam.
3.CAUTION : There are no serviceable parts inside the
Laser Unit. Do not disassemble the Laser Unit. Replace
the complete Laser Unit if it malfunctions.
4.CAUTION : The CD,MD and DVD player uses invisible
laser radiation and is equipped with safety switches which
prevent emission of radiation when the drawer is open and
the safety interlocks have failed or are defeated. It is
dangerous to defeat the safety switches.
5.CAUTION : If safety switches malfunction, the laser is able
to function.
6.CAUTION : Use of controls, adjustments or performance of
procedures other than those specified here in may result in
hazardous radiation exposure.
Please use enough caution not to see the beam directly or touch it in case of an adjustment or operation check.

3.2.9 Removing the DVD pickup assembly (See Fig.17 to 19)
• Remove the mechanism control board.
(1) From the bottom of the body, turn the feed gear in the di-
rection of the arrow to move the DVD pickup outwards. (See Fig.17.)
(2) Remove the screw J attaching the thrust spring. (See
Fig.17.)
(3) Remove the DVD pickup assembly upward on the L.S.gear
side and release from sub shaft at joint r. Move the lead screw of the DVD pickup assembly in the direction of the arrow to release from joint s. (See Fig.18.)
Caution:
• When releasing the lead screw at joint s, the L.S.collar comes off at the end of the lead screw. When reas­sembling, reattach the L.S.collar to the lead screw and engage joint s. (See Fig.18.)
• When reattaching the L.S.collar, reattach it to the point s of the lead screw, and to the rod (M). Make sure that the L.S.collar is set on the rod (M) spring. (See Fig.18.)
(4) Remove the screw K attaching the rack spring/ rack plate
on the DVD pickup. (See Fig.19.)

ADJUSTMENT

4.1 Test instruments required for adjustment

(1) Digital oscilloscope (100MHz) (2) Jitter meter (3) Digital tester (4) Electric voltmeter (5) Tracking offset meter (6) Test Disc : VT501 or VT502 (7) Extension studs : STDV001-3P (8) Extension cable : EXTDV002-30P

4.3 Connection method

Connection procedure
(1) Attach the front chassis assembly to the main board. (2) Attach the heat sink and rear bracket to the main board. (3) Attach the extension studs to the DVD mechanism assembly. (4) Connect the DVD mechanism assembly and the main board with a extension cable.

4.2 Standard measuring conditions

Power supply voltage DC14.4V(11 to 16V)
Load impedance 4(2 Speakers connection) Line Output 20K
Caution:
Be sure to attach the heat sink and rear bracket onto the power amplifier IC and regulator IC respectively, before supply the power. If voltage is applied without attaching these parts, the power amplifier IC and regulator IC will be destroyed by heat.

4.4 Adjustment method for jitter

After replacing the pickup, set the unit in the service mode to display a jitter value on the LCD. Confirm that the jitter value measured with a jitter meter is within 12% of the jitter value displayed on the LCD. If it is within 12%, then adjustment is not necessary. If the measured jitter value is outside the 12% tolerance range, perform the following adjustments.
4.4.1 Adjustment procedure
(1) Connect each unit shown in Fig.1. (2) Set the unit to the service mode and display a jitter value (hex data) on the LCD. (3) Turn each of the screws a, b and c, by a half-turn per step, in the direction that reduces the jitter value in order to minimize it .
(Do not turn a screw more than a half turn at a time, but adjust the screws in the cycle of a b c a.)
(4) After completing the adjustment, secure the screws with screw lock paint.

4.5 Jitter value conversion table

Load the test DVD and set the unit to the service mode. A jitter value converted to the hex value is displayed on the LCD. Refer to the corresponding decimal notation value shown in the following Jitter Conversion Table. The adjustment is OK if the jitter value measured with a jitter meter is within 12% of the jitter value displayed on the LCD. If the measured jitter value is outside the 12% tolerance range, adjust it to minimize the difference between the measured value and the displayed value.
