PROTECTION OF EYES FROM LASER BEAM DURING SERVICING

This set employs laser. Therefore, be sure to follow carefully the instructions below when servicing.

WARNING!!

WHEN SERVICING, DO NOT APPROACH THE LASER EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS NECESSARY TO CONFIRM LASER BEAM EMISSION. BE SURE TO OBSERVE FROM A DISTANCE OF MORE THAN 30cm FROM THE SURFACE OF THE OBJECTIVE LENS ON THE OPTICAL PICK-UP BLOCK.

s Caution: Invisible laser radiation when

open and interlocks defeated avoid exposure to beam.

s Advarsel: Usynlig laserståling ved åbning,

når sikkerhedsafbrydere er ude af funktion. Undgå udsættelse for stråling.

VAROITUS!

Laiteen Käyttäminen muulla kuin tässä käyttöohjeessa mainitulla tavalla saataa altistaa käyt-täjän turvallisuusluokan 1 ylittävälle näkymättömälle lasersäteilylle.

VARNING!

Om apparaten används på annat sätt än vad som specificeras i denna bruksanvising, kan användaren utsättas för osynling laserstrålning, som överskrider gränsen för laserklass 1.

CAUTION

Use of controls or adjustments or performance of procedures other than those specified herin may result in hazardous radiation exposure.

ATTENTION

L’utillisation de commandes, réglages ou procédures autres que ceux spécifiés peut entraîner une dangereuse exposition aux radiations.

ADVARSEL

Usynlig laserståling ved åbning, når sikkerhedsafbrydereer ude af funktion. Undgå udsættelse for stråling.

This Compact Disc player is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT label is located on the rear exterior.

Precaution to replace Optical block

(KSS-213F)

Body or clothes electrostatic potential could

ruin laser diode in the optical block. Be sure

ground body and workbench, and use care the

clothes do not touch the diode.

1) After the connection, remove solder shown in right figure.

NOTE ON BEFORE STARTING REPAIR

1. Forced discharge of electrolytic capacitor of power supply block

When repair is going to be attempted in the set that uses relay circuit in the power supply block, electric potential is kept charged across the electrolytic capacitors (C101, 102) even though AC power cord is removed. If repair is attempted in this condition, secondary defect can occur. In order to prevent the secondary trouble, perform the following measures before starting repair work.

Discharge procedure

1 Remove the AC power cord.

11 22

2 Connect a discharging resistor at an end of lead wire that

has clips at both ends. Connect the other end of the lead wire to metal chassis.

3 Contact the other end of the discharging resistor to the

positive (+) side (+VH) of C101. (For two seconds)

4 Contact the same end of the discharging resistor as step

3 to the negative (-) side (-VH) of C102 in the same way.

(For two seconds)

5 Check that voltage across C101 and C102 has decreased

to 1 V or less using a multimeter or an oscilloscope.

Select a discharging resistor referring to the following table.

Charging voltage (V) Discharging

(C101, 102) resistor (Ω)

25-48 100 3 87-A00-247-090

49-140 220 5 87-A00-232-090

Note: The reference numbers (C101, C102) of the electrolytic capacitors can change depending on the models. Be sure to check the

reference numbers of the charging capacitors on schematic diagram before starting the discharging work.

2. Check items before exchanging the MICROCOMPUTER

Be sure to check the following items before exchanging the MICROCOMPUTER. Exchange the MICROCOMPUTER after confirming that the MICROCOMPUTER is surely defective.

2-1. Regarding the HOLD terminal of the MICROCOMPUTER

When the HOLD terminal (INPUT) of the MICROCOMPUTER is “H”, the MICROCOMPUTER is judged to be operating correctly. When this terminal is “L”, the main power cannot be turned on. Therefore, be sure to check the terminal voltage of the HOLD terminal before exchange. When the MICROCOMPUTER is not defective, the HOLD terminal can also go “L” when the POWER AMPLIFIER has any abnormalities that triggers the abnormality detection circuit on the MAIN C. B. that sets the HOLD terminal to “L”.

• Good or no good judgement of the MICROCOMPUTER

1 Turn on the AC main power.

11 22

2 Confirm that the main power is turned on and the HOLD terminal of the MICROCOMPUTER keeps the “H” level or not.

22 33

3 When the HOLD terminal is “L” level, the abnormality detection circuit is judged to be working correctly and the

MICROCOMPUTER is judged to be good.

– 4 –

Page 5

In such a case, check also if the POWER AMPLIFIER circuit or power supply circuit has any abnormalities or not.

2-2. Regarding reset

There are cases that the machine does not work correctly because the MICROCOMPUTER is not reset even though the AC power cord is re-inserted, or the software reset (pressing the STOP key + POWER key) is performed. When the above described phenomenon occurs, it can lead to wrong judgement as if the MICROCOMPUTER is defective and to exchange the MICROCOMPUTER. In such a case, perform the forced-reset by the following procedure and check good or no good of the MICROCOMPUTER.

1 Remove the AC power cord.

FRONT C.B

FRONT C.B

2 Short both ends of the electrolytic capacitor C113 that is connected to VDD of the MICROCOMPUTER with tweezers.

22 33

3 Connect the AC power cord again. If the MICROCOMPUTER returns to the normal operation, the MICROCOMPUTER is

good.

Note: The reference number or MICROCOMPUTER pin number of transistor (Q110) and electrolytic capacitor (C113) can change depending

on the models. Be sure to check the reference numbers on schematic diagram before starting the discharging work.

2-3. Confirmation of soldering state of MICROCOMPUTER

Check the soldering state of the MICROCOMPUTER in addition to the above described procedures. Be sure to exchange the MICROCOMPUTER after surely confirming that the trouble is not caused by poor soldering but the MICROCOMPUTER itself.

CD TEST MODE

1. How to Activate CD Test Mode

While pressing and holding the function button, insert the AC plug. When the test mode starts, the message, “TEST” appears on the display.

2. How to Cancel CD Test Mode

Press the POWER button or remove the AC plug. * The test mode is cancelled by other function keys during play.

3. Function and Usage of CD Test Mode

No Mode Button for Display Operation Contents

Activation

1 Start Mode All lights are All FL are lit. • FL check

lit. • Microcomputer check

2 Search Mode STOP button Reading • Laser diode is lit during the • APC circuit check

mode. • Laser current measurement

• Focus search continuous • Focus-search waveform check operation. *1 • Focus-error waveform check

• Spindle motor continuous kick. (DRF is ignored during search

mode)

3 Play Mode PLAY button Normal • Normal playback. • All servo circuits check

• Focus search continues if • DRF check TOC READ cannot be read.

4 Traverse PAUSE Normal • Tracking Servo OFF/ON. • Tracking balance check

Mode button The OFF/ON operation repeats

each time the PAUSE button is pressed.

5 Sled Mode FF button TEST • PU moves to inner track. *2

At the same time, the lens is • Sled circuit check kicked to inner track. • Tracking circuit check

RWD button TEST • PU is moves to outer track. *2 • Mechanism operation check

At the same time, the lens is • PU check kicked to outer track.

6 Spindle Mode REC button All lights are • When the button is pressed, • Spindle circuit check

lit. the spindle motor operates in • Spindle motor check

forward rotation (rough speed). Then, the button is pressed again, it operates in reverse rotation. When the button is pressed again, operation stops.

*1 … When focus search operates continuously more than 10 minutes, the protection circuit may start due to generation of heat in the

driver IC. If this happens, turn off the power, leave the unit for a while, and then, restart.

*2 … Carefully monitor the gear against damage, as the sled motor rotates while the FF or RWD button is pressed even when the

pickup is located at innermost or outermost.
