SAFETY PRECAUTION FOR SERVICE MANUAL

Precaution to be taken when replacing and servicing the Laser Pickup.

The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class 1 Requirements.
However, the following precautions must be observed during servicing to protect your eyes against exposure to the Laser beam.

(1) When the cabinet has been removed, the power is turned on without a compact disc, and the Pickup is on a position outer than

the lead-in position, the Laser will light for several seconds to detect a disc. Do not look into the Pickup Lens.
(2) The LaserPower Output of thePickup inside the unit andreplacement service parts have alreadybeen adjusted prior to shipping.
(3) No adjustment to the Laser Power should be attempted when replacing or servicing the Pickup.
(4) Under no circumstances look directly into the Pickup Lens at any time.
(5) CAUTION - Use of controls or adjustments, or performance of procedures other than those specified herein may result in

hazardous radiation exposure.

IMPORTANT SERVICE NOTES (FOR U.K. ONLY)

Before returning the unit to the customer after completion of a
repair or adjustment it is necessary for the following withstand
voltage test to be applied to ensure the unit is safe for the
customer to use.

Notes:

1. Description of the "FM IF Adjustment" is not carried on this Man­ual. It is because the IF coil in the FM front end section has been
best adjusted in the factory so that its further adjustment is not
needed at the field. When replacing the FM front end assembly, no
adjustment is needed either.

2. The parts in the FM front end section are prepared in a complete
unit, so you can't obtain each part individually.

CHAPTER 5. CIRCUIT DESCRIPTION

[1] 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 pico-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.

• The indicated voltage in each section is the one measured by Digi­tal Multimeter between such a section and the chassis 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.

CHAPTER 7. FLOWCHART

[1] Troubleshooting

1. When the CD does not function

The CD section may not operate when the objective lens of the optical pickup is dirty. 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.

Parts code

1. CD optical pickup Lens cleaner disc UDSKA0004AFZZ

HOW TO USE

1.

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.

2.

Place the CD cleaner disc onto the CD disc tray with the brush side down, then
press the play button.

3.

You will hear music for about 20 seconds and the CD player will automatically stop.
If it still play continuously, press the stop button.

Cleaning fluid

CAUTION

The CD lens cleaner should be effective for 30-50 operations, however if the
brushes become worn out earlier then please replace 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 contact with the eyes. In the event of this
happening then drink and / or rinse with clean water and seek medical advice.
The CD cleaner disc must not be used on car CD players or on computer CD-ROM
drives.
All rights reserved. Unauthorized duplicating, broadcasting and renting this product
is prohibited by law.

Cleaner disc

2. When a CD cannot be played

2.1. "E-CD01" is displayed.

1) Check the power to IC1 (LC78648E), the presence of the clock signal (16.9344 MHz) and the status of the RESET terminal (pin 67 on IC1).

2) Does the pickup move to the PICKUP-IN Switch (NSW1) position?
If (1) and (2) are OK, check the system microcomputer (especially the communication line with the DSP).

2.2. Pressing the CD operation key is accepted, but playback does not occur.

1) Focus-HF system check

2) Tracking system check

3) Spin system check

4) PLL system check

5) Others

Yes

No

"Initialization" is not possible. Data cannot be read. Check the VCO-PLL (Pin76~80 on IC1)

The tracking servo is not activated.
Check the peripheral circuits at pins 16, 17 and 22 on IC1, and
FFC1.

A normal jump operation cannot be completed or the beginning
of the track cannot be found.
Check the around pin 22 on IC1.

system.

(3) Spin system check.

Press the OPEN/CLOSE switch without inserting a disc, and
then try starting the play operation.

1. The turntable rotates a little?

Yes The spin driver circuit is OK.

(Waveform drawing Figure 5)

No

2. The turntable doesn't rotate. Check around pin 24 on IC1, pins 3 and 4 on IC2, and CNS3A/
CNS3B.

Check the PDO waveform. (Figure 6)

Check around pins 76~80 on IC1.

Figure 6

(5) Others.

The HF waveform is normal and the time is displayed normally,
but no sound is produced. Or the sound has dropouts.

Is pin 69 (C2F) on IC1 "L"? No There are too many error flags on a damaged disc which makes

error correction impossible.

Yes

1. When playing at normal speed.

Check the peripheral circuit at pin 39 (DOUT) on IC1 and the
waveform (Figure 7).

If OK, Check the unit.

Check again using a known good disc.
