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
3

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.
5

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).
7

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.

“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.
