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.

Laser Diode Properites

• Material: GaAlAs

• Wavelength: 780 nm

• Emission Duration: continuous

• Laser Output Power: less than 44.6 µW*
* This output is the value measured at a distance of 200 mm

from the objective lens surface on the Optical Pick-up Block.

CAUTION

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

DISC MAGAZINE GETTING OUT PROCEDURE
ON THE POWER SUPPL Y IS OFF

Remove the CASE (LOWER) assembly beforehand

1) Press the lever (ML) assy to arrow direction.

2) Removal the magazine assy.

Note: Take out the magazine only when the tray is completely within the

magazine. If the disk or tray is sticking out, turn on the power and
eject the magazine.

Flexible Circuit Board Repairing

• Keep the temperature of the soldering iron around 270 ˚C dur­ing repairing.

• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).

• 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.

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:

BUS cable

CDX-727

Adjustment Method:

1. Connect this set to the master unit (e.g. MDX-C670/
C670RDS), 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 elevator shaft
positions in a range between comb teeth A to B.

Procedure:

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

2. Put the set into play mode by loading the disc.

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.

2. Put the set into play mode by loading the disc.

3. Press the = AMS + button, and check the tra verse wav e­form*.

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

• FOCUS GAIN ADJUSTMENT
(COARSE ADJUSTMENT)

This adjustment is to be performed when replacing the following
parts.

• Optical Pick-up Block

• RV14

[RF BOARD] – Conductor Side –

CNJ12

• When gain is lowered...

The set does not play because of no focus operation.

• When gain is highered...

Operation noise is heard due to a scratch or a dust, then opera­tion will be unstable.

RV14

IC11

Procedure:

1. Set RV14 (RF board) to the standard position.

2. Check that there is not an abnormal amount of operation noise
(white noise) from the 2-axis devise. If there is, turn RV14
slightly clockwise.

Note:

The components identi­fied by mark ! or dotted
line with mark ! are criti­cal for safety.
Replace only with part
number specified.

Note:

Les composants identifiés par
une marque ! sont critiques
pour la sécurité.
Ne les remplacer que par une

• U : B+ Line.

• H : adjustment for repair.

• Power voltage is dc 14.4V and fed with regulated dc power

supply from CD changer controller.

• Voltages and waveforms are dc with respect to ground

under no-signal conditions.
no mark : CD PLAY

: Impossible to measure

∗

• Voltages are taken with a VOM (Input impedance 10 MΩ).

Voltage variations may be noted due to normal produc­tion tolerances.

• Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal produc­tion tolerances.

• Circled numbers refer to waveforms.
