gear D clockwise (Figure 4) to move the CD mechanism to tray
No.3 position.This is confirmed by checking the gear up down
board position by the marking as indicated on the main chassis as
shown in Figure 5.

Perform steps 1, 2, 9 and 10 of the disassembly method to remove the
CD changer mechanism.
3.1. How to remove CD Disc (See Fig. 2~5)
1. When CD is at play position (Figure 2), rotate reduction gear C
clock-wise as shown in Figure 3 Until disc tray is at stock position,
then rotate further to eject the disc tray so that CD can be removed
from the tray.

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.
• The number 1 to 12 are waveform number shown in page 5-2.

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.
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

Check the TE waveform at pin 17 on IC1.
If the waveform shown in Figure 4 appears and soon after NO
DISC appears ?
Yes
No
"Initialization" is possible, but play is not possible ?
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.

(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 ?
YesThe 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.

When a disc is loaded, start play operation.
The HF waveform is normal, but the TOC data cannot be read.
Check the PDO waveform. (Figure 6)
Check around pins 76~80 on IC1.

(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" ?NoThere are too many error flags on a damaged disc which makes
error correction impossible.
Yes
