1.1 Safety Precautions
SECTION 1
Important Safety 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.

1.2 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 DVD 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 conducti ve sheet) or an iron plate over it before placing the
traverse unit (optical pickup) on it.
(2) Grou nd yourself
Use an anti-static wrist strap to release any static electricity built up in your body.
(caption)

1M
Conductive material
(conductive sheet) or iron plate
(3) Handling the optical pickup
• In order to maintain quality during transport and before insta llation, both sides of the lase r diode on the replacement o ptical
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) I t is not possib le 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 CDpickup may be destroyed by static electricity.)
• In the assembly, be sure to remove solder from the short land after connecting the flexible wire.

3.3 Maintenance of laser pickup
(1) Cl eaning the pick up lens
Before you replace the pick up, please try to clean the lens
with a alcohol soaked cotton swab.
(2) Life of the laser di ode
When the life of the laser diode has expired, the following
symptoms will appear.
• The level of RF output (EFM output:ampli tude of eye
pattern) will be low.
Is RF output
1.0
±
0.35Vp-p?
NO
Replace it.
YES
O.K
(3) Semi-fixed resistor on the APC PC board
The semi-fixed resistor on the APC printed circuit board
which is attached to the pickup is used to adjust the laser
power.Since this adjustment should be performed to match
the characteristics of the whole optical block, do not touch
the semi-fixed resistor. If the laser power is lower than the
specified value,the laser diode is almost worn out, and the
laser pickup should be replaced. If the semi-fixed resistor
is adjusted while the pickup is functioning normally,the l aser pickup may be damaged due to excessive current.
3.4 Replacement of laser pickup
Turn off the power switch and, disconnect the power cord
from the ac outlet.
Replace the pickup with a normal one. (Refer to
"Pickup Removal" on the previous page)
Plug the power cord in, and turn the power on.
At this time,check that the laser emits for about 3seconds
and the objective lens moves up and down.
Note: Do not observe the laser beam directly.
Play a disc.
Check the eye-pattern at TP1.
Finish.
