IMPORTANT SERVICE NOTES (FOR U.S.A. ONLY)

BEFORE RETURNING THE AUDIO PRODUCT

(Fire & Shock Hazard)

Before returning the audio product to the user, perform the

following safety checks.

1. Inspect all lead dress to make certain that leads are not

pinched or that hardware is not lodged between the chassis

and other metal parts in the audio product.

2. Inspect all protective devices such as insulating materials,

cabinet, terminal board, adjustment and compartment covers

or shields, mechanical insulators etc.

3. To be sure that no shock hazard exists, check for leakage

current in the following manner.

* Plug the AC line cord directly into a 120 volt AC outlet.

* Using two clip leads, connect a 1.5k ohm, 10 watt resistor

paralleled by a 0.15µF capacitor in series with all exposed

metal cabinet parts and a known earth ground, such as

conduit or electrical ground connected to earth ground.

* Use a VTVM or VOM with 1000 ohm per volt, or higher,

sensitivity to measure the AC voltage drop across the

resistor (See diagram).

* Connect the resistor connection to all exposed metal parts

having a return path to the chassis (antenna, metal cabinet,

screw heads, knobs and control shafts, escutcheon, etc.)

and measure the AC voltage drop across the resistor.

All check must be repeated with the AC line cord plug connection

reversed.

Any reading of 0.3 volt RMS (this corresponds to 0.2 milliamp.

AC.) or more is excessive and indicates a potential shock

hazard which must be corrected before returning the audio

product to the owner.

Specifications for this model are subject to change without

prior notice.

0203 Open/Close SW High → Low not functioning

[Error during skip operation]

0302 Pickup-in SW is not detected

0306 During Disc 1 search, Open/Close SW or Clamp SW

or Disc SW do not change to low.

0307 Clamp SW Low → High not functioning

0308 Clamp SW High → Low not functioning

Since this CD system incorporates the following automatic

adjustment functions, readjustment is not needed when

replacing the pickup. Therefore, different PWBs and pickups

can be combined freely.

Each time a disc is changed, these adjustments are

performed automatically. Therefore, playback of each disc

can be performed under optimum conditions.

Items adjusted automatically

(1) Offset adjustment (The offset voltage between the head

amplifier output and the VREF reference voltage is

compensated inside the IC.)

* Focus offset adjustment

* Tracking offset adjustment

(2) Tracking balance adjustment (waveform drawing 12-2

EFBL)

(3) Gain adjustment (The gain is compensated inside the IC

so that the loop gain at the gain crossover frequency will

be 0dB.)

* Focus gain adjustment

* Tracking gain adjustment

• The indicated voltage in each section is the one measured

by Digital Multimeter between such a section and the chas-

sis with no signal given.

1. In the tuner section,

( ) indicates AM

< > indicates FM stereo

2. In the main section, a tape is being played back.

3. In the deck section, a tape is being played back.

( ) indicates the record state.

4. In the power section, a tape is being played back.

5. In the CD section, the CD is stopped.

• Parts marked with “ ” ( ) are important for

maintaining the safety of the set. Be sure to replace these

parts with specified ones for maintaining the safety and

performance of the set.

NOTES ON SCHEMATIC DIAGRAM

• Resistor:

To differentiate the units of resistors, such symbol as K and

M are used: the symbol K means 1000 ohm and the symbol

M means 1000 kohm and the resistor without any symbol is

ohm-type resistor. Besides, the one with “Fusible” is a fuse

type.

• Capacitor:

To indicate the unit of capacitor, a symbol P is used: this

symbol P means micro-micro-farad and the unit of the

capacitor without such a symbol is microfarad. As to

electrolytic capacitor, the expression “capacitance/withstand

voltage” is used.

(CH), (TH), (RH), (UJ): Temperature compensation

(ML): Mylar type

(P.P.): Polypropylene type

• Schematic diagram and Wiring Side of P.W.Board for this

model are subject to change for improvement without prior

notice.

1. CD optical pickup Lens cleaner disc UDSKA0004AFZZ

TROUBLE SHOOTING

When the CD does not function

When the CD section does not operate when the objective lens of the optical pickup is dirty, this section may not operate. Clean

the objective lens, and check the playback operation. When this section does not operate even after the above step is taken, check

the following items.

Remove the cabinet and follow the trouble shooting instructions.

"Track skipping and/or no TOC (Table Of Contents) may be caused by build up of dust other foreign matter on the laser pickup

lens. Before attempting any adjustment make certain that the lens is clean. If not, clean it as mentioned below."

Turn the power off.

Gently clean the lens with a lens cleaning tissue and a small amount of isopropyl alcohol.

Do not touch the lens with the bare hand.

HOW TO USE

CAUTION

Cleaner Fluid

Cleaner disc

Using the brush in the cleaner cap, apply 1 or 2 drops of the cleaning fluid to the

brush on the CD cleaner disc which has the mark next to it.

Place the CD cleaner disc onto the CD disc tray with the brush side down,then

press the play button.

You will hear music for about 20 seconds and the CD player will automatically stop.

If it continuous to tum, press the stop button.

The CD lens cleaner should be effective for 30-50 operations, however if the

brushes become worn out earlier then please the cleaner disc.

If the CD cleaner brushes become very wet then wipe off any excess fluid with a soft

cloth.

Do not drink the cleaner fluid or allow it to come in contact with the eyes. In the

event of this happening then drink and / or rines with clean water and seek medical

advice.

The CD cleaner disk must not be used on car CD players or on computer CD ROM

drives.

(1) Check the power to IC2 (LC78641E), the presence of the clock signal (16.93 MHz) and the status of the RESET terminal

(pin 71 on IC2).

(2) Did the pickup move to the PICKUP-IN Switch (SW4) position?

If (1) and (2) are OK, check the system microcomputer (especially the communication line with the DSP).

2. Pressing the CD operation key is accepted, butplayback does not occur.

(1) Focus-HF system check

(2) Tracking system check

(3) Spin system check

(4) PLL system check

(5) Others

If the level is not normal, check around pins 27~29 on IC1.

1. Is focus servo activated? (Waveform drawing 36-2)

Pins 1~11 on IC1

Check the laser diode driver Q3 peripheral circuit.

Focus error circuit (pins 20 and 21 on IC1)

When a disc is loaded, start playback operation.

2. Does DRF change from "L" to "H"?

Is the disc rotating?

3. Is the HF waveform normal? (Waveform drawing 36-3)

Check the spin system.

If the disc is spinning and a HF waveform is generated,

DRF will go H.

Check the laser diode driver Q3 peripheral circuit.

(1) Focus-HF system check

Although a CD is inserted and the cover is closed, "NO

DISC" is displayed.

1. Did the pickup move to the PICKUP-IN Switch (SW4)

position?

Sled motor (M2)

Press the OPEN/CLOSE switch (SW1) without inserting a

disc, and try starting the playback operation.

2. Does the focus (lens) move up and down?

(Waveform drawing 36-1).

Check the focus peripheral circuit.

3. Is the laser lit?

Spindle motor (M1).

4. Is the turntable rotating?

Is pin 35 (C2F) on IC2 "L"?

Yes

The HF waveform is normal and the time is displayed

normally, but no sound is produced. Or the sound has

dropouts.

(5) Others

There are too many error flags on a damaged disc which

makes error correction impossible.

Check again using a known good disc.

1. When playing at normal speed

Check the peripheral circuit at pin 37 (DOUT) on IC2 and

the waveform (Figure 38-2).

If both 1. and 2. are OK.

When a disc is loaded, start play operation.

(4) PLL system check

The HF waveform is normal, but the TOC data cannot be

read.

Check the PDO waveform. (Figure 38-1)
