!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.

Safety precaution

!Please use enough caution not to see the beam directly or touch it in case of an

adjustment or operation check.

Preventing static electricity

1.Grounding to prevent damage by 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.

2.About the earth processing for the destruction prevention 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.

2-1 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.

2-2 Ground yourself

Use an anti-static wrist strap to release any static electricity built up in your body.

3. Handling the optical pickup

1. 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.)

2. 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.

4.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

Soldering

Attention when traverse unit is decomposed

1.Solder is put up before the card wire is removed from connector on

the CD substrate as shown in Figure.

(When the wire is removed without putting up solder, the CD pick-up

assembly might destroy.)

2.Please remove solder after connecting the card wire with

when you install picking up in the substrate.

*Please refer to "Disassembly method" in the text for pick-up and how to

detach the substrate.

Maintenance of laser pickup

(1) Cleaning the pick up lens

Befor you replace the pick up, please try to

clean the lens with a alcohol soaked cotton

swab.

(2) Life of the laser diode (Fig.1)

When the life of the laser diode has expired,

the following symptoms wil appear.

(1) The level of ARF output (EFM output:ampli

tude of eye pattern) will be low.

Replacement of laser pickup

Is ARF output

1.1 0.15Vp-p? Replace it.

NO

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 laser

pickup may be damaged due to excessive current.

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 ARF.

Finish.
