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.
1-4 (No.MA101)

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) Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit. (2) Cut off the shorted part of the flexible cable using nippers, etc. after replacing the optical pickup. For specific details, refer to the
replacement procedure in the text. Remove the anti-static pin when replacing the traverse unit. Be careful not to take too long a
time when attaching it to the connector. (3) Handle the flexible cable carefully as it may break when subjected to strong force. (4) It is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn it.

1.4 Attention when traverse unit is decomposed

*Please refer to "Disassembly method" in the text for the CD pickup unit.
• Apply solder to the short land before the flexible wire is disconnected from the connector on the CD pickup unit. (If the flexible wire is disconnected without applying solder, the CD pickup may be destroyed by static electricity.)
• In the assembly, be sure to remove solder from the short land after connecting the flexible wire.

1.5 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.

ADJUSTMENT

4.1 Adjustment method

4.1.1 Test instruments required for adjustment
(1) Digital oscilloscope (100MHz) (2) Jitter meter (3) Digital tester (4) Digital multi meter (For voltage measurement) (5) Electric voltmeter (6) Frequency counter (7) Tracking offset meter (8) Test Disc : VT501 or VT502 (9) Extension studs : STDV001-3P
(10) Extension cable : EXTAV70X-50PF
4.1.3 Connection method
When confirming the mechanism movement, connect each unit shown in Fig.1.
Connection procedure
(1) Connect the front panel assembly to the main board. (2) Attach the extension studs to the DVD mechanism assembly. (3) Connect the DVD mechanism assembly and the main board with a extension cable. (4) Connect the hideaway unit and the main board with an attached cable. (5) Fix the mechanism cover with tape in the top drive unit. (6) Hang the mechanism cover on the rear bracket. (7) Spread the wooden boards under the top drive unit in order to put it up shown in Fig.1. (8) Attach the display unit to the top drive unit.
4.1.2 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.

4.1.5 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 12.0% of the jitter value displayed on the LCD. If it is within 12.0%, then adjustment is not necessary. If the measured jitter value is outside the 12.0% tolerance range, perform the following adjustments.
4.1.5.1 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.

(No.MA101)1-37
4.1.6 Jitter value conversion table
Load the test disc 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 12.0% of the jitter value displayed on the LCD. If the measured jitter value is outside the 12.0% tolerance range, adjust it to minimize the difference between the measured value and the displayed value.

4.2.10 Touch panel manual operation proofreading procedure
Procedure 1 Proofreading
(1) Set the main unit in a touch panel proofreading mode. (2) Push the center of the figure of a cross in a circle of green (81h to 89h) on the panel in turn.
a) Push for each 3 points of the upper part of 81h and 82h and 83h with a thumb of the right hand (or, left hand) on the
panel from a direction.
b) Push 84h with a thumb of the left hand from the left course.
c) Push 85h with the middle finger of the right hand or the middle finger of the left hand from center direction. d) Push 86h with a thumb of the right hand from the right course. e) Push for each 3 points of the lower part of 87h and 88h and 89h with a thumb of the right hand (or, left hand) under the
panel from a direction. (3) When proofreading was completed normally, OK is displayed. (4) Repeat since a beginning when NG was displayed. (5) After proofreading completion, turn off the power supply and confirm it again.
Procedure 2 Confirmation
(1) Switch on the main unit and turn the main unit into normal movement. (2) Push a screen key of GUI and set the main unit in the mode that "NAME" is displayed in the right bottom. (3) Push "NAME" in order to let a screen display a keyboard of British number and push all keys in order to confirm misrecognition. (4) When misrecognition occurred, proofread it since a beginning.
