1. Use of Active Subwoofer
1.1. Checking Player when Active Subwoofer isnot used
1. Thisunituses the active subwoofer to supplythe power of the
component, and the active subwoofer shouldbe connected to the
component to check operational conditions of the component.
2. Ifthe active subwoofer isnot availabledue to repairof the unit,
use the following equipment.

overseas domesticuse)
2. Safety Precautions
2.1. GENERALGUIDELINES
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, carryout the following leakage current checks to
prevent the customer from being exposed to shock hazards.
2.1.1. LEAKAGE CURRENTCOLD CHECK
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
7

reading must be . Figure 1
2.1.2. LEAKAGE CURRENTHOTCHECK (See Figure 1 .)
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
capacitors, between each exposed metallicpart on the set and a
good earth ground such as awater pipe, as shownin Figure 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 isoutside of the limits specified,
there isapossibilityof ashock hazard, and the equipment should
be repaired and rechecked before itisreturned to the customer.
3. Prevention of Electro Static Discharge (ESD) to
Electrostatically Sensitive (ES) Devices
Some semiconductor(solidstate) devices canbe damagedeasilybystatic electricity. 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).
1. Immediatelybefore handling anysemiconductor component or
8
PDFcreated withpdfFactoryProtrialversion www.pdffactory.com

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 aluminum
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 removal device. Some solder
removal devices not classified as "anti-static(ESDprotected)"
can generate electrical charge sufficient 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, aluminum 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 bodilymotions 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).

4. Before Repair and Adjustment (Using Active
Subwoofer)
Disconnect AC power, discharge PowerSupplyCapacitors C546~C549 through a 10 , 10 W
resistortoground.
DO NOTSHORT-CIRCUITDIRECTLY (witha screwdriverblade, forinstance), as this may
destroysolidstate devices.
Afterrepairs are completed, restore powergraduallyusing a variac, toavoidovercurrent.
Current consumption at AC 230 - 240 V, 50 Hz inNO SIGNALmode shouldbe ~ 420 mA (ForGS)
& ~620 mA (ForGN).
Current consumption at AC 100/110 V, 50/60Hz inNO SIGNALmode shouldbe ~835 mA (For
GC).
5. Protection Circuitry
The protection circuitrymayhave operatedif eitherof the following conditions are noticed:
-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.
6. Precaution of Laser Diode
