Be sure to disconnect the mains cord before adjusting the voltage selector.
Use a minus(-) screwdriver to set the voltage selector (on the rear panel) to the voltage setting for the
area in which the unit will be used. (If the power supply in your area is 117V or 120V, set to the
“127V” position.)
Note that this unit will be seriously damaged if this setting is not made correctly. (There is no voltage
selector for some countries, the correct voltage is already set.)
TOP PREVIOUS NEXT
Page 11
2 Before Repair and Adjustment
TOP PREVIOUS NEXT
Disconnect AC power, discharge Power Supply Capacitors C531~C534, C588~C589, C598~C599
and C954 through a 10Ω, 5W resistor to ground.
DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may
destroy solid state devices.
After repairs are completed, restore power gradually using a variac, to avoid overcurrent.
Current consumption at AC 110/127/220~230V, 50/60 Hz in NO SIGNAL (vol. min, at CD mode) &
AC 240 V, 50 Hz should be ~770mA and ~370mA respectively.

3 Protection Circuitry
TOP PREVIOUS NEXT
The protection circuitry may have operated if either of the following conditions are noticed:
● No sound is heard when the power is turned on.
● Sound stops during a performance.
The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative
speaker connection wires are
“shorted”, or if speaker systems with an impedance less than the indicated rated impedance of the
amplifier are used.
If this occurs, follow the procedure outlines below:
1. Turn off the power.
2. Determine the cause of the problem and correct it.
3. Turn on the power once again after one minute.
Note :
When the protection circuitry functions, the unit will not operate unless the power is first turned off
and then on again.

Page 14
4.1 General Guidelines
TOP PREVIOUS NEXT
1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts
which have been overheated or damaged by the short circuit.
2. After servicing, see to it that all the protective devices such as insulation barriers, insulation
papers shields are properly installed.
3. After servicing, make the following leakage current checks to prevent the customer from
being exposed to shock hazards.
4.1.1 Leakage Current Cold Check
4.1.2 Leakage Current Hot Check (See Figure 1)
TOP PREVIOUS NEXT
Page 15
4.1.1 Leakage Current Cold Check
TOP PREVIOUS NEXT
1. Unplug the AC cord and connect a jumper between the two prongs on the plug.
2. Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each
exposed metallic cabinet part on the equipment such as screwheads, connectors, control shafts,
etc. When the exposed metallic part has a return path to the chassis,the reading should be
between 1MΩ and 5.2MΩ.
When the exposed metal does not have a return path to the chassis, the reading must be ·.
Figure 1
TOP PREVIOUS NEXT
Page 16
4.1.2 Leakage Current Hot Check
(See Figure 1)
TOP PREVIOUS NEXT
1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this
check.
2. Connect a 1.5kΩ, 10 watts resistor, in parallel with a 0.15•F capacitor, between each exposed
metallic part on the set and a good earth ground such as a water pipe, as shown in Figure 1.
3. Use an AC voltmeter, with 1000 ohms/volt or more sensitivity, to measure the potential across
the resistor.
4. Check each exposed metallic part, and measure the voltage at each point.
5. Reverse the AC plug in the AC outlet and repeat each of the above measurements.
6. The potential at any point should not exceed 0.75 volts RMS. A leakage current tester
(Simpson Model 229 or equivalent) may be used to make the hot checks, leakage current must
not exceed 1/2 milliamp. In case a measurement is out ofthe limits specified, there is a
possibility of a shock hazard, and the equipment should be repaired and rechecked before it is
returned to the customer.

5 Prevention of Electro Static Discharge (ESD)
to Electrostatically Sensitive (ES) Devices
TOP PREVIOUS NEXT
Some semiconductor (solid state) devices can be damaged easily by electricity. Such components
commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are
integrated circuits and some field-effect transistorsand semiconductor “chip” components. The
following techniques should be used to help reduce the incidence of component damage caused by
electro static discharge (ESD).
1. Immediately before handling any semiconductor component or semiconductor-equiped
assembly, drain off any ESD on your body by touching a known earth ground. Alternatively,
obtain and wear a commercially available discharging ESD wrist strap, whichshould be
removed for potential shock reasons prior to applying power to the unit under test.
2. After removing an electrical assembly equiped with ES devices, place the assembly on a
conductive surface such as aluminium foil, to prevent electrostatic charge build up or exposure
of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
4. Use only an anti-static solder remover device. Some solder removal devices not classified as
“anti-static (ESD protected)” can generate electrical charge to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to
damage ES devices.
6. Do not remove a replacement ES device from its protective package until immediately before
you are ready to install it. (Most replacement ES devices are packaged with leads electrically
shorted together by conductive foam, aluminium foil orcomparable conductive material).
7. Immediately before removing the protective material from the leads of a replacement ES
device, touch the protective material to the chassis or circuit assembly into which the device
will be installed.
Caution
Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
8. Minimize body motions when handling unpackaged replacement ES devices. (Otherwise
harmless motion such as the brushing together of your clothes fabric or the lifting of your foot
Page 18
from a carpeted floor can generate static electricity (ESD) sufficient todamage an ES device).

6.1 About lead free solder (PbF)
TOP PREVIOUS NEXT
Distinction of PbF P.C.B.:
P.C.B.s (manufactured) using lead free solder will have a PbF stamp on the P.C.B.
Caution:
● Pb free solder has a higher melting point than standard solder; Typically the melting point is
50 - 70°F (30 - 40°C) higher. Please use a high temperature soldering iron. In case of
soldering iron with temperature control,please set it to 700 ± 20°F (370 ± 10°C).
● Pb free solder will tend to splash when heated too high (about 1100°F/600°C).
● When soldering or unsoldering, please completely remove all of the solder on the pins or
solder area, and be sure to heat the soldering points with the Pb free solder until it melts
enough.

TOP PREVIOUS NEXT
This word combines the abbreviations of Matsushita Electric Industrial Co. Ltd. and High
Performance Media Access Technology, and is a trademark of Microsoft Corporation. The products
with the HighMAT logo shown below are made according to the HighMATstandard.
HighMAT is a format that allows users to save digital contents such as photographs, audio, and
images on a CD. This gives consistency in the way of reading data when general consumer products
(such as DVD players) and PCs are used, and thus, itis easy to operate for the user.

12.2 Why use HighMAT?
TOP PREVIOUS NEXT
Up to now, there was no harmonized standard from playing digital content stored in CD-ROM
formats (including CD-R) on consumer products like DVD players.Therefore, we used to have
problems such as follow:
● There was no common play list or attached information on contents, which is called metadata.
● The data compression method differed according to the equipment.
● As the number of CD-ROMs recorded increased retrieved the contents became more difficult.
● Because display and operation methods were different depending on the equipment, the play
order of the content on the same disc could change.

12.3 The advantages of using HighMAT
TOP PREVIOUS NEXT
Applying the HighMAT standard will solve the following problems and will improve usability.
● It will create a common user interface for both PC and consumer products.
● Regardless of the types of consumer products, such as DVD players, portable CD players, car
stereos, and micro computers, a consistent way to pay for digital content will be created and it
will make it easier to retrieve data.
Page 34
● You can also play digital content on the disc, which was created in accordance with the
HighMAT format with a conventional CD-ROM player.

TOP PREVIOUS NEXT
How to distinguish Laser destruction/damage
Confirmation 1
Remove cover of mechanism block so that you will see the lens of optical pickup.
Confirm emission of laser at the moment when power switch is turned on.
If there is no laser emission, laser diode is faulty.
Confirmation 2
While holding “Pause” and “Open/Close” button, press “Display” button on the remote controller.
Unit display laser current on FL.
From the reading of display, you can judge if laser diode is damaged or not.
Reading on the right side should be less than 70. If reading is more than 70, laser is damaged.
Page 41
How to confirm if Optical Pickup is OK
Confirmation 1
1. Confirmation of jitter value with test disc. (Refer below for how to check jitter)
2. Lens cleaning.
3. Reconfirm jitter value.
4. Perform tile adjustment. (Refer to tilt adjustment)
5. Reconfirm jitter value. (To confirm jitter value, while pressing “Pause” and “Open/Close”
button, press numeric “5” on remote controller.)
Unit display jitter value on FL.
Confirmation 2
If servo is very unstable due to optical error and you cannot confirm jitter value, clean the lens and
check appearance of pick up unit (cutting coil of actuator, etc), then check circuitry.

Optical pickup could be damaged due to the static electricity discharged from human body. Wear
proper protection gear against static electricity during optical pickup and its peripheral repair. (Refer
to “Cautions to Be Taken When HandlingOptical Pickup”.)
● Do not touch laser diode, actuator and their peripherals.
● Do not check laser diode with a tester and such. (The tester will be destroyed.)
● For short-circuiting or removing laser diode, the use of an anti-static soldering iron is
recommended. (Recommended model: HAKKO ESD product)
● Solder the land of the flexible cable in the optical pickup.
Note:
If an anti-static soldering iron is not available, short-circuit the terminal surface of the flexible cable
and then the land using a clip or equivalent device.
