1. Safety precautions for AC Cord (For GS only)
2. Before Use (Caution)
Be sure todisconnect the AC cordbefore adjusting the voltage selector.
Use a minus(-) screwdrivertoset the voltage selector(on the rearpanel) tothe voltage setting
forthe area inwhichthe unit will be used. (If the powersupplyinyourarea is 110-127V or220-
240V.)
Note that this unit will be seriouslydamagedif this setting is not made correctly. (There is no
voltage selectorforsome countries, the correct voltage is alreadyset.)
3. Before Repair and Adjustment
Disconnect AC power, discharge PowerSupplyCapacitors C5815, C5818, C9513, C9533, C9534,
C9816 and C9817 through a 10 , 5W resistortoground.
DO NOTSHORT-CIRCUITDIRECTLY (witha screwdriverblade, forinstance), as this may
destroysolidstate devices.
Afterrepairs are completed, restore powergraduallyusing a variac, toavoidovercurrent.
Current consumption at AC 100/110V at 50/60 Hz & AC 240V at 50Hz inNO SIGNAL(vol. min, at
CD mode) shouldbe ~500mA .
4. Protection Circuitry
The protection circuitrymayhave operatedif eitherof the following conditions are noticed:
5
PDFcreated withpdfFactoryProtrialversion www.pdffactory.com

-Nosound isheard when the power isturned on.
-Sound stops during aperformance.
The function of this circuitryis toprevent circuitrydamage if, forexample, the positive and
negative speakerconnection wires are
“shorted”, orif speakersystems withanimpedance less thanthe indicatedratedimpedance of
the amplifierare used.
If this occurs, followthe procedure outlines below:
1. Turn off the power.
2. Determine the cause of the problem and correct it.
3. Turn on the power once againafter one minute.
Note :
Whenthe protection circuitryfunctions, the unit will not operate unless the poweris first turned
off and thenon again.
5. Safety Precautions
5.1. General Guidelines
1. When servicing, observe the original lead dress. Ifashort circuit
isfound, replace all parts which have been overheated or
damaged bythe short circuit.
2. After servicing, see to itthat 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.
5.1.1. Leakage Current ColdCheck
1. Unplug the AC cord and connect ajumper between the two
prongs on the plug.
2. Measure the resistance value, with an ohmmeter, between the
jumpered AC plug and each exposed metalliccabinet part on the
equipment such as screwheads, connectors, control shafts, etc.
When the exposed metallicpart has areturn path to the chassis,
the reading shouldbe between 1M and 5.2M .
When the exposed metal does not have areturn path to the
chassis, the reading must be .

5.1.2. Leakage Current Hot Check / (See Figure1)
1. Plug the AC cord directlyinto the AC outlet. Donot use an
isolation transformer for thischeck.
2. Connect a1.5k , 10 watts resistor, inparallel with a0.15 F
capacitor, between each exposed metallicpart on the set and a
good earth ground such as awater pipe, as showninFigure 1.
3. Use an AC voltmeter, with 1000 ohms/voltor more sensitivity, to
measure the potential across the resistor.
4. Check each exposed metallicpart, and measure the voltage at
each point.
5. Reverse the AC plug inthe AC outlet and repeat each of the above
measurements.
6. The potential at anypoint shouldnot exceed 0.75 volts RMS. A
leakage current tester (Simpson Model 229 or equivalent) maybe
used to make the hot checks, leakage current must not exceed 1/2
milliamp. Incase ameasurement isout of the limits specified,
there isapossibilityof ashock hazard, and the equipment should
be repaired and rechecked before itisreturned to the customer.
6. Prevention of Electro Static Discharge (ESD) to
Electrostatically Sensitive (ES) Devices
Some semiconductor(solidstate) devices canbe damagedeasilybyelectricity. Such
components commonlyare calledElectrostaticallySensitive (ES) Devices. Examples of typical
ES devices are integratedcircuits and some field-effect transistors and semiconductor“chip”
components. The following techniques shouldbe usedtohelpreduce the incidence of
component damage causedbyelectrostatic discharge (ESD).
7
PDFcreated withpdfFactoryProtrialversion www.pdffactory.com

1. Immediatelybefore handling anysemiconductor component or
semiconductor-equipped assembly, drainoff anyESDon your
bodybytouching aknownearth ground. Alternatively, obtainand
wear acommerciallyavailabledischarging ESDwrist strap, which
shouldbe removed for potential shock reasons prior to applying
power to the unitunder test.
2. After removing an electrical assemblyequipped with ES devices,
place the assemblyon aconductive surface such as aluminium
foil, to prevent electrostaticcharge buildup or exposure of the
assembly.
3. Use onlyagrounded-tipsoldering iron to solder or unsolder ES
devices.
4. Use onlyan anti-staticsolder remover device. Some solder
removal devices not classified as “anti-static(ESDprotected)”
can generate electrical charge to damage ES devices.
5. Donot use freon-propelled chemicals. These can generate
electrical charges sufficient to damage ES devices.
6. Donot remove areplacement ES device from its protective
package until immediatelybefore you are readyto install it. (Most
replacement ES devices are packaged with leads electrically
shorted together byconductive foam, aluminium foil or
comparableconductive material).
7. Immediatelybefore removing the protective material from the
leads of areplacement ES device, touch the protective material to
the chassisor circuitassemblyinto which the device will be
installed.
Caution
Besure no power isapplied to the chassisor circuit, and observe
all other safetyprecautions.
8. Minimize bodymotions when handling unpackaged replacement
ES devices. (Otherwise harmless motion such as the brushing
together of your clothes fabricor the lifting of your foot from a
carpeted floor can generate staticelectricity(ESD)sufficient to
damage an ES device).

7. Handling the Lead-free Solder
7.1. About lead free solder (PbF)
Distinction of PbF P.C.B.:
P.C.B.s (manufactured) using leadfree solderwill have a PbF stampon the P.C.B.
Caution:
-Pb free solder has ahigher melting point than standard solder;
Typicallythe melting point is50 -70°F (30 -40°C)higher. Please
use ahigh temperature soldering iron. Incase of soldering iron
with temperature control, please set itto 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 completelyremove all of
the solder on the pins or solder area, and be sure to heat the
soldering points with the Pb free solder until itmelts enough.
8. Precaution of Laser Diode

followings:
1. Donot disassemblethe optical pick up unit, since radiation from

2. Donot adjust the variableresistor on the pick up unit. Itwas
alreadyadjusted.
3. Donot look at the focus lens using optical instruments.
4. Recommend not to look at pick up lens for along time.

9. Cautions to be taken when handling Optical Pickup
The laserdiode usedinside optical pickup couldbe destroyeddue tostatic electricityas a
potential difference is causedbyelectrostatic loaddischargedfromclothes orhumanbody.
Handling the parts carefullytoavoidelectrostatic destruction during repair.
9.1. Handling Optical Pickup
1. Donot impact on optical pickup as the unitstructurallyuses an
extremelyprecise technology.
2. Short-circuitthe flexiblecableof optical pickup remove from the
circuitboard using ashort-circuitpinor clipinorder to prevent
laser diode from electrostaticdestruction (Refer to Fig. 9.1and
Fig. 9.2)
3. Donot handleflexiblecables forciblyas thismaycause snapping.
Handlethe parts carefully(Refer to Fig. 9.1)
4. Anew optical pickup isequipped with an anti-staticflexiblecable.
After replacing and connecting to the flexibleboard, cut the anti-
staticflexiblecable. (Refer to Fig. 9.1)

9.2. Replacing Precautions for Optical Pickup Unit
DVD/CD Optical Pickup
The optical pickup bywhichpart supplywas carriedout attaches the short cliptothe flexible
boardforlaserdiode electrostatic discharge damage prevention. Please remove the short clip

and be sure tocheck that the short land is open, before connecting. (Please remove solder,
whenthe short land short-circuits.)
9.3. Grounding for Preventing ElectrostaticDestruction
1. Human bodygrounding
Use the anti-staticwrist strap to discharge the staticelectricity
accumulated inyour body. (Refer to Fig. 9.2)
2. Work place grounding
Place aconductive material (conductive sheet) or iron board
where optical pickup isplaced. (Refer to Fig. 9.2)
Note :
Keep your clothes awayfrom optical pickup as wrist strap does not
release the staticelectricitycharged inclothes.
