1. SAFETY PRECAUTIONS
1.1. 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, make the following leakage current checks to
prevent the customer from being exposed to shock hazards.
1.1.1. 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 thechassis,
the reading shouldbe between 1M and 5.2M . / When the
exposed metal does not have areturn path to the chassis, the
reading must be .

Figure 1
1.1.2. 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 isoutsideof the limits specified,
there isapossibilityof ashock hazard, and the equipment should
be repaired and rechecked before itisreturned to the customer.
2. 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 transistorsand semiconductor"chip"
components. The following techniques shouldbe usedtohelpreduce the incidence of
component damage causedbyelectrostatic discharge (ESD).
1. Immediatelybefore handling anysemiconductor component or
semiconductor-equipped assembly, drainoff anyESDon your
4

bodybytouching aknownearth ground. Alternatively, obtainand
wear acommerciallyavailabledischargingESDwrist 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 alminum 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, alminum foil or comparable
conductivematerial).
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 hamless motion such as the brushing
together of your clothes fabricor the lifting of your foot from a
carpeted floor can generate staticelectricity(ESD)sufficient
todamage an ES device).

3. PRECAUTION OF LASER DIODE
4. HANDLING PRECAUTIONS FOR TRAVERSE DECK
The laserdiode inthe optical pickup maybreak downdue topotential difference causedby
static electricityof clothes orhumanbody.
Sobe careful of electrostatic break downduring repairof the optical pickup.
4.1. Handling of optical pickup
1. Donot subject the optical pickup to staticelectricityas itis
extremelysensitive to electrical shock.
2. To prevent the breakdownof the laser diode, an antistatic
shorting pinisinserted into the flexibleboard (FPCBoard). /
When removing or connecting the short pin, finish the job inas
short times as possible.
3. Becareful not to applyexcessive stress to the flexibleboard (FPC
6

Board).
4. Donot turn the variableresistor (Laser power adjustment). / Ithas
alreadybeen adjusted.
4.2. Grounding for electrostaticbreakdownprevention
1. Human bodygrounding / Use the antistaticwrist strap to
discharge the staticelectricityfrom your body.
2. Work tablegrounding / Put aconductive material (sheet) or steel
sheet on the area where the optical pickup isplaced and ground
the sheet.
Caution
The staticelectricityof your clothes will not be grounded through
the wrist strap. So take care not to let your clothes touch the
optical pickup.

7.1. Self-diagnosis
As a newfeature, this unit has an“optical pick-up problemdiagnosis function” and “a tilt
adjustment confirmation function” built in. Use the following procedure toefficientlydetermine
the problemand adjusttilt.If "NO DISC" is displayed, before exchanging the optical pick-up,
carryout problemdiagnosis first. If the present laserdriving current is over55, the optical pick-
up mayneedtobe exchanged.

Note:
Carryout diagnosiswithin3minutes of turning the uniton. (The
player’scurrent can increase as itwarms up, so turn the unitoff
and allow itto cool downbefore diagnosis.)
7.2. Cautions to BeUsed Before Replacing the Optical Pickup Unit
and SpindleMotor Assembly
Before replacing the optical pickup unit and spindle motorassembly, check the total using
hours foreachof them. The checking method is as follows:

Cautions tobe takenwhenreplacing the optical pickup
The optical pickup maybreak downdue tothe static electricityof humanbody. Take proper
protection measures against static electricitybefore repairing the parts around the optical
pickup. (See the page describing the PREVENTION OFSTATIC ELECTRICITYDISCHARGE.)
1. Donot touch the areas around the laser diode and actuator.
2. Donot judge the laser diode with atester. (The tester will be
damaged easily.)
3. Itisrecommended to use adestaticized soldering iron for short-
circuiting or removing the laser diode. (Recommended soldering
iron) HAKKO ESDProduct
4. Solder the land of the flexiblecableinthe optical pickup.
Note:
-When using asoldering iron which isnot destaticized, short-circuit
the terminal face of the flexiblecase with aclip. After that, short-
circuitthe land.
-After the repairing work iscompleted, remove the solder according
to the correct procedure showninthisTechnical Guide.
