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 perfor m 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 metal part and a known good earth ground.
Measure the AC voltage across the resistor with the AC
voltmeter.
Move the resistor connection to each exposed metal part,
particularly any exposed metal part having a return path to
the chassis, and meausre the AC voltage across the resistor.
Now, reverse the plug in the AC outlet and repeat each
measurement. Voltage measured any must not exceed 0.75 V
AC (r.m.s.). This corresponds to 0.5 mA AC (r.m.s.).

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 m ust 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.

In regard with component parts appearing on the silk-screen pr inted side (parts side) of the PWB diagrams, the
parts that are printed over with black such as the resistor ( ), diode ( ) and ICP ( ) or identified by the " "
mark nearby are critical for safety.
When replacing them, be sure to use the parts of the same type and rating as specified by the manufacturer.
(Except the J and C version)

MX-G50

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

In the equipment which uses optical pick-up (laser diode), optical pick-up is destroyed by the static electricity of
the work environment.
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.

(caption)
Anti-static wrist strap

Conductive material
(conductive sheet) or iron plate

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

Attention when CD mechanism assembly is decomposed

*Please refer to "Disassembly method" in the text for pick-up and how to
detach the CD mechanism assembly.

1. Remove the CD changer unit.

2. Remove the CD changer mechanism.

3. Solder is put up before the card wire is removed from the pickup unit
connector on the CD mechanism assembly.
(When the card wire is removed without putting up solder, the CD pick-up
assembly might destroy.)

4. Please remove solder after connecting the card wire with the pickup unit
connector when you install picking up in the substrate.

Maintenance of laser pickup

(1) Cleaning 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 diode
When the life of the laser diode has expired,
the following symptoms will appear.

1. The level of RF output (EFM output:ampli
tude of eye pattern) will below.

Is the level of

RFOUT under

1.1V 0.2Vp-p?

YES

O.K

NO

Replace it.

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.

(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.

Check the eye-pattern at TP1.

Finish.

Functions

Crystal resonator connection
(4.5MHz/7.2MHz)

Serial data input : FMIN is selected when DVS is set to 1.
The input frequency range is from 10 to 160MHz.
The signal is passed through a built-in divide-by-two prescaler
and then supplied to the swallow counter.
A1 though the range of divisor setting is from
272 to 65, 535, the actual divisor is twice the setting since
there is also a built-in divide-by-two prescaler.

Serial data input : AMIN is selected when DVS is set to 0.
Serial data input : When SNS is set to 1 :
The input frequency range is form 2 to 40MHz
The signal is supplied directly to the swallow counter.
The range of divisor setting is from 272 to
65, 535 and the actual divisor will be the value set.
Serial data input : When SNS is set to 0 :
The input frequency ranges is from 0.5 to 10MHz.
The signal is supplied directly to a 12-bit
programmable divider.
The range of divisor setting is from 4 to 4,095 and the
actual divisor will be the value set.

Functions

Used as the synchronization clock when serial data is input
to the LC72131 (DI ), or when serial data is output (DO).

Inputs serial data sent from the controller to the LC72131M.

Output serial data sent from the LC72131M to the controller.
The content of the output data is determined by the serial
data DOCO to DOC2.

The LC72131M power supply (VDD=4.5 to 5/5V)
The power on reset circuit operates when power is first applied.

The LC72131M ground.

Dedicated output pins
The output states are determined by BO1 to BO4 in the
serial data.
'Data"=0:Open
=1:Low
The pins go to the open state after the power-on reset.
An 8Hz time base signal can be output from BO1 when TBC
in the serial data is set to 1.
Note that the ON impedance of the BO1 pin is higher than
that of the other pins (BO2 to BO4)

Pins used for both input and output
The input or output state is determined by bits IOC1 and IOC2
in the serial state.
'Data"=0:Input port
=1:Output port
When specified for use as an input port :
The input state is transmitted to the controller through the
DO pin.
'Input state"=Low:data value 0
=High:data value 1
When specified for use as an output port :
The output state is determined by bits IO1 and IO2 in the
serial sate.
'Data"=0:Open
=1:Low
These pins go to the input port state after the power-on reset.

PLL Charge pump output
When the frequency generated by dividing the Local oscillator
frequency by N is higher than the reference frequency,
a high level will be output from the PD in. similarly, when that
frequency is lower, a low level will be output.
The PD pin goes to the high impedance state when the
frequencies agree.

The MOS transistor used for the PLL active Low-pass filter.

IF counter

The input frequency range is from 0.4 to 12MHz.
The signal is supplied directly to the IF counter.
The result from the IF counter MBS is output through
the DO pin.
There are four measurement periods: 4, 8, 32 or 64ms.
