SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK­UP BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electro­static breakdown because of the potential difference generated by
the charged electrostatic load, etc. on clothing and the human body .
During repair, pay attention to electrostatic breakdown and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode emis­sion, observe from more than 30 cm away from the objectiv e lens.

US/Canadian model:

If the optical pick-up block is defective, please replace the whole
optical pick-up block.
Never turn the semi-fixed resistor located at the side of optical
pick-up block.

• Be careful not to apply force on the conductor when soldering
or unsoldering.

Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be dam­aged by heat.

Notes on handling discs

A dirty or defective disc may cause sound drop-outs during
playback. To enjoy optimum sound, handle the disc as
follows.

• Handle the disc by its edge, and to keep the disc clean,

do not touch the unlabeled surface. (fig.

• Do not stick paper or tape on the disc. (fig.

• Keep your discs in their cases or disc magazines when

not in use.
Do not expose discs to direct sunlight or heat sources
such as hot air-ducts. Do not leave discs in a car parked
in direct sunlight where there can be a considerable
rise in the temperature inside the car. (fig.

• Before playing, clean the discs with an optional
cleaning cloth. Wipe each disc in the direction of the

D

arrows. (fig.

Do not use solvents such as benzine, thinner,
commercially available cleaners or antistatic spray
intended for analog discs.

• Discs with special shapes (heart-shaped discs,

octagonal discs etc.) cannot be played on this unit.
Attempting to do so may damage the unit. Do not use
such discs.

Notes on discs

If you use the discs explained below, the sticky residue can
cause the disc to stop spinning and may cause malfunction
or ruin your discs.
Do not use second-hand or rental CDs that have a sticky
residue on the surface (for example from peeled-off stickers
or from ink, or glue leaking from under the stickers).

• There are paste residue. Ink is sticky. (fig.
Do not use rental CDs with old labels that are beginning to
peel off.

• Stickers that are beginning to peel away, leaving a

sticky residue. (fig.

Do not use your discs with labels or stickers attached.

• Labels are attached. (fig.

Notes on CD-R/CD-RW discs

• You can play CD-Rs/CD-RWs (recordable CDs/
rewritable CDs) designed for audio use on this unit
(fig.

• Some CD-Rs/CD-RWs (depending on the equipment
used for its recording or the condition of the disc) may
not play on this unit.

Remarques sur la manipulation des disques

Un disque sale ou défectueux peut provoquer des pertes de son
à la lecture. Manipuler le disque comme suit pour obtenir un
son optimal.

• Manipuler le disque par son arête et le maintenir dans un

état propre, ne pas le toucher sur la surface non
imprimée. (fig.

• Ne pas coller de papier ou de bande adhésive sur le
disque. (fig.

• Conservez vos disques dans leurs boîtiers ou des
pochettes de rangement lorsqu’ils ne sont pas utilisés.
Ne pas laisser les disques en plein soleil ou près d’une
source de chaleur comme des conduits d’air chaud. Ne pas
laisser les disques dans une voiture garée en plein soleil
car la température de l’habitacle risque d’augmenter
considérablement. (fig.

• Avant la lecture, essuyer les disques avec un chiffon de
nettoyage en option. Essuyer chaque disque dans le sens
des flèches. (fig.

Ne pas utiliser de solvants tels que de la benzine, du diluant,
des produits de nettoyage vendus dans le commerce ou de
vaporisateurs anti-statiques destinés aux disques
analogiques.

• Il n’est pas possible d’utiliser les disques de formes

spéciales (en forme de cœur ou octogonaux, etc.) avec cet
appareil. Vous risquez d’endommager l’appareil.
N’essayez jamais de lire ces disques.

Remarques sur les disques

Si vous utilisez les disques décrits ci-dessous, le résidu adhésif
risque de provoquer l’arrêt de la rotation du disque et
d’entraîner un dysfonctionnement ou d’endommager vos
disques.
N’utilisez pas de CD de seconde main ou de location qui
présentent des résidus adhésifs à la surface (par exemple
d’étiquettes décollées ou d’encre, de colle dépassant de
l’étiquette).

• Résidus de colle. L’encre colle. (fig.
N’utilisez pas de CD de location avec d’anciennes étiquettes
qui commencent à se décoller.

MECHANICAL ADJUSTMENT

• Elevator Height (Address) Adjustment

SECTION 4

Note: This adjustments is necessary when the system controller (IC201),

variable resistor (RV201), slider (R), slider (L), or chassis (ELV)
was replaced for any repair.

Connection:

power supply

(DC 14.4 V)

master unit

+

GND

BUS cable

compact disc changer

CONTROL connector
(CN901)

Adjustment Method:

1. Connect this set to the master unit (e.g. MDX-C7970/C7970R),
load a disc magazine, and place the set vertically as shown
below.

2. Connect the regulated power supply to the master unit, and
turn the power on.

3. Press the DISC button on the master unit and select DISC 5.

4. At this time, if the elevator shaft does not position between
comb teeth A and B at addresses 5 and 6 as shown below,
adjust the following.

5. Press repeatedly the DISC + and – buttons on the master unit
so that the elevator shafts moves from address 6 to address 5,
or from 5 to 6. At this time, adjust RV201 on the main board
so that the elevator shaft positions smoothly between comb
teeth A and B.

6. Further, place the set horizontally and make same adjustment
as mentioned above.

7. After adjustment at addresses 5 to 6 is finished, check all op­erations from addresses 1 to 10 with the set placed vertically
and horizontally respectively to confirm that the ele vator shaft
positions in a range between comb teeth A to B.

ELECTRICAL CHECK

CDX-656/656X

Note:

1. This check is performed with the set placed horizontally.

2. Power supply voltage: DC14.4 V (more than 3 A).

3. Be sure to use the disc “YEDS-18” parts code: 3-702-101-01, but only
when indicated.

Procedure:

1. Connect the oscilloscope to TP (RFO) and TP (VC) on the RF
board.

2. Put the set into play mode by loading the disc (YEDS-18).

3. Confirm that oscilloscope waveform is clear and check RF sig­nal level is correct or not.

Note:

Clear RF signal waveform means that the shape “◊” can be clearly distin­guished at the center of the waveform.

VOLT/DIV: 200 mV
TIME/DIV: 500 ns

When observing the eye pattern, set the oscilloscope to AC range
and raise the vertical sensitivity so that it may be easily seen.

2. Put the set into play mode by loading the disc (YEDS-18).

3. Press the . , > buttons on the master unit, and check the
traverse waveform*.

4. Confirm that the oscilloscope waveform is symmetrical on the
top and bottom in relation to 0 V dc, and check this level.

* Traverse waveform: This is the tracking error wave form appears

when crossing the track.
