1. This design of this product contains special hardware and many circuits and components specially
for safety purposes. For continued protection, no changes should be made to the original design
unless authorized in writing by the manufacturer. Replacement parts must be identical to those
used in the original circuits. Services should be performed by qualified personnel only.
2. Alterations of the design or circuitry of the product should not be made. Any design alterations of
the product should not be made. Any design alterations or additions will void the manufacturer`s
warranty and will further relieve the manufacture of responsibility for personal injury or property
damage resulting therefrom.
3. Many electrical and mechanical parts in the products have special safety-related characteristics.
These characteristics are often not evident from visual inspection nor can the protection afforded
by them necessarily be obtained by using replacement components rated for higher voltage,
wattage, etc. Replacement parts which have these special safety characteristics are identified in
the Parts List of Service Manual. Electrical components having such features are identified by
shading on the schematics and by ( ) on the Parts List in the Service Manual. The use of a
substitute replacement which does not have the same safety characteristics as the recommended
replacement parts shown in the Parts List of Service Manual may create shock, fire, or other
hazards.
4. The leads in the products are routed and dressed with ties, clamps, tubings, barriers and the
like to be separated from live parts, high temperature parts, moving parts and/or sharp edges
for the prevention of electric shock and fire hazard. When service is required, the original lead
routing and dress should be observed, and it should be confirmed that they have been returned
to normal, after re-assembling.
5. Leakage currnet check (Electrical shock hazard testing)
After re-assembling the product, always perform an isolation check on the exposed metal parts
of the product (antenna terminals, knobs, metal cabinet, screw heads, headphone jack, control
shafts, etc.) to be sure the product is safe to operate without danger of electrical shock.
Do not use a line isolation transformer during this check.
Plug the AC line cord directly into the AC outlet. Using a "Leakage Current Tester", measure
the leakage current from each exposed metal parts of the cabinet , particularly any exposed
metal part having a return path to the chassis, to a known good earth ground. Any leakage
current must not exceed 0.5mA AC (r.m.s.)
Alternate check method
Plug the AC line cord directly into the AC outlet. Use an AC voltmeter having, 1,000 ohms
per volt or more sensitivity in the following manner. Connect a 1,500 10W resistor paralleled by
a 0.15 F AC-type capacitor between an exposed

1. This equipment has been designed and manufactured to meet international safety standards.
2. It is the legal responsibility of the repairer to ensure that these safety standards are maintained.
3. Repairs must be made in accordance with the relevant safety standards.
4. It is essential that safety critical components are replaced by approved parts.
5. If mains voltage selector is provided, check setting for local voltage.

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.
MX-S6MD
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.
1.1. 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/MD players.
Be careful to use proper grounding in the area where repairs are being performed.
1.1.1. Ground the workbench
1. 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.
1.1.2. Ground yourself
1. Use an anti-static wrist strap to release any static electricity built up in your body.
(caption)
Anti-static wrist strap
Conductive material
(conductive sheet) or iron plate
1.1.3. 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.
1.2. 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

Replacement of laser pickup
(MD)
Change the MD pickup by referring to
"Removing the MD pickup" in the
disassembly method.
1. Cleaning of pickup lens
(1) Prior to changing the pickup, clean the pickup lens.
(2) For cleaning the lens, use the following cotton swab after
mearsing it in alcohol.
Product No : JCB-B4 Manufacturer : Nippon Cotton Swab
2. Confirmation of the service life of laser
diode when the service life of the laser
diode has been exhausted, the following
symptoms will appear.
Set the pickup to [TEST] mode according
to the procedures described in the
adjustment method.
Adjust the laser power.
(1) Recording will become impossible.
(2) The RF output (EFM output and eye-pattern amplitude)
will become lower.
Completion the disc.
(3) The drive current required for light emitting of laser diode
will be increased.
Confirm the service life according to the following flow chart.
Completion of changing the MD pickup.

CAUTION
Since this system is designed to perform magnetic
recording, the laser power ten times or over of the
conventional MD player will be output. Therefore, be
sure to perform not only adjustment and operation
of this system so carefully as not to directly look at
the laser beam or touch on the body.
YES
O.K.
3. Method of measuring the drive current
of laser diode
When the voltage measured at each side of R337,
it become 120mV or over, the service life of laser
diode is judged to have been exhausted.

4.Semi-solid state resistors on the
APC board.
The semi-solid state resistor on the APC board
attached to the pickup is used for adjusting the laser
power. Since these resistor should be adjusted in
pair according to the characteristics of the optical
block, be sure not touch on the resistors.
Since the service life of the laser diode will be
exhausted when the laser power is low, it is
necessary to change the pickup.
Meanwhile, do not pickup.
Otherwise, the pickup will be damaged due to over
current.

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 specified
value, the laser diode is almost worm out,
and the pickup should be replaced.
If the semi-fixed resistor is adjust while the
pickup is functioning normally, the laser
