1. Before Repair and Adjustment

Disconnect AC power, discharge PowerSupplyCapacitors C501, C604, C608, C906 & C908

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 230V, 50 HzinNO SIGNALmode

shouldbe ~150 mA.

2. 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.

5. Handling the Lead-free Solder

5.1. 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.

6. Handling Precautions For Traverse Deck

The laserdiode inthe traverse deck (optical pickup) maybreak downdue topotential difference

causedbystatic electricityof clothes orhumanbody.

So, be careful of electrostatic breakdownduring repairof the traverse deck (optical pickup).

Handling of CD traverse deck (optical pickup)

1. Donot subject the traverse deck (optical pickup) to static

electricityas itisextremelysensitive to electrical shock.

2. The short land between the No.4(LD)and No.5(GND)pins on the

flexibleboard (FFC)isshorted with asolder build-up to prevent

damage to the laser diode.

3. Take care not to applyexcessive stress to the flexibleboard (FPC

board).

4. Donot turn the variableresistor (laser power adjustment). Ithas

alreadybeen adjusted.

Grounding forelectrostatic breakdownprevention

1. Human bodygrounding

Use the anti-staticwrist strap to discharge the staticelectricity

from your body.

2. Work tablegrounding

Put aconductive material (sheet) or steel sheet on the area where

the traverse deck (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

traverse deck (optical pickup).

Caution whenReplacing the Optical Pickup :

The traverse has ashort point shorted with solder to protect the

laser diode against electrostatics breakdown. Besure to remove

the solder from the short point before making connections.

7. Caution for AC Mains Lead

8. Operation Check and Main Component

Replacement Procedures

“ATTENTION SERVICER”

Some chassiscomponents mayhave sharp edges. Becareful when

disassembling and servicing.

1. Thissection describes procedures for checking the operation of

the major printed circuitboards and replacing the main

components.

2. For reassemblyafter operation checks or replacement, reverse

the respective procedures.Special reassemblyprocedures are

described onlywhen required.

3. Select items from the following index when checks or

replacement are required.

4. Refer the Parts No. on the page of "MainComponent Replacement

Procedures", ifnecessary.
