- CD Player Service Precautions

1. For pickup unit(CXX1480) handling, please refer
to"Disassembly"(see page 38).
During replacement, handling precautions shall be
taken to prevent an electrostatic discharge(protection
by a jumper-solder).

2. During disassembly, be sure to turn the power off
since an internal IC might be destroyed when a con­nector is plugged or unplugged.

3. Please checking the grating after changing the pickup
unit(see page 35).

4. In this product, because the memory capacity of the
microcomputer is insufficient, the test mode is not
installed. However grating of the pickup unit can be
confirmed.

For resistors and capacitors in the circuit diagrams, their resistance values or
capacitance values are expressed in codes:

Ex. *Resistors
Code Practical value
123 12k ohms
103 10k ohms

*Capacitors
Code Practical value
103 0.01µF
101/10 100µF/10V

The > mark found on some component parts indicates
the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of
identical designation.

Symbol indicates a resistor.
No differentiation is made between chip resistors and
discrete resistors.

NOTE :

Symbol indicates a capacitor.

6. ADJUSTMENT

6.1 CD ADJUSTMENT

1) Precautions

• This unit uses a single power supply (+5V) for the reg­ulator. The signal reference potential, therefore, is
connected to VREF(approx. 2.1V) instead of GND.
If VREF and GND are connected to each other by mis­take during adjustments, not only will it be impossi­ble to measure the potential correctly, but the servo
will malfunction and a severe shock will be applied to
the pick-up. To avoid this, take special note of the fol­lowing.
Do not connect the negative probe of the measuring
equipment to VREF and GND together. It is especially
important not to connect the channel 1 negative
probe of the oscilloscope to VREF with the channel 2
negative probe connected to GND.
Since the frame of the measuring instrument is usual­ly at the same potential as the negative probe, change
the frame of the measuring instrument to floating sta­tus.
If by accident VREF comes in contact with GND,
immediately switch the regulator or power OFF.

• Always make sure the regulator is OFF when connect­ing and disconnecting the various filters and wiring
required for measurements.

• Before proceeding to further adjustments and mea­surements after switching regulator ON, let the player
run for about one minute to allow the circuits to stabi­lize.

• Since the protective systems in the unit's software are
rendered inoperative in test mode, be very careful to
avoid mechanical and /or electrical shocks to the sys­tem when making adjustment.

• The RFI and RFO signals are easy to oscillate because
of a wide band. When observing them, insert a resis­tor of about 1 kΩ to the series.

• This equipment will not guarantee the load ejection
operation when the mechanical unit is turned upside
down. In particular, if the ejection operation is incor­rectly performed and recovery is disabled, the recov­ery is enabled by resetting a product or turning ACC
off to on.

2) Test Mode
This mode is used for adjusting the CD mechanism
module of the device.

• Test mode starting procedure

Reset while pressing the 4 and 6 keys together.

• Test mode cancellation
Switch ACC, back-up OFF.

• After pressing the EJECT key, do not press any other
key until the disk is completely ejected.

• If the ] or [ key is pressed while focus search is in
progress, immediately turn the power off (otherwise
the actuator may be damaged due to adhesion of the
lenses).

DEH-1400,14

• Note :

The grating angle of the PU unit cannot be adjusted after the PU unit is changed. The PU unit in the CD mecha-

nism module is adjusted on the production line to match the CD mechanism module and is thus the best adjusted
PU unit for the CD mechanism module. Changing the PU unit is thus best considered as a last resort. However, if
the PU unit must be changed, the grating should be checked using the procedure below.

• Purpose :

To check that the grating is within an acceptable range when the PU unit is changed.

• Symptoms of Mal-adjustment :

If the grating is off by a large amount symptoms such as being unable to close tracking, being unable to perform

track search operations, or taking a long time for track searching.

• Method :

• Measuring Equipment • Oscilloscope, Two L.P.F.

• Measuring Points • E, F, VREF

• Disc • ABEX TCD-784

• Mode • TEST MODE

• Checking Procedure

1. In test mode, load the disc and switch the 5V regulator on.

2. The display will change, returning to "81" on the fourth press.

3. As shown in the diagram above, monitor the LPF outputs using the oscilloscope and check that the phase differ­ence is within 75° . Refer to the photographs supplied to determine the phase angle.

4. If the phase difference is determined to be greater than 75° try changing the PU unit to see if there is any
improvement. If, after trying this a number of times, the grating angle does not become less than 75° then the
mechanism should be judged to be at fault.

• Note

Because of eccentricity in the disc and a slight misalignment of the clamping center the grating waveform may be

seen to "wobble" ( the phase difference changes as the disc rotates). The angle specified above indicates the aver­age angle.

• Hint

Reloading the disc changes the clamp position and may decrease the "wobble".

6.3 ERROR MODE

- Error Messages

If a CD is not operative or stopped during operation due to an error, the error mode is turned on and cause(s) of the
error is indicated with a corresponding number. This arrangement is intended at reducing nonsense calls from the
users and also for facilitating trouble analysis and repair work in servicing.

(1) Basic Indication Method

1) When SERRORM is selected for the CSMOD (CD mode area for the system), error codes are written to DMIN (min­utes display area) and DSEC (seconds display area). The same data is written to DMIN and DSEC. DTNO remains
in blank as before.

2) Head unit display examples
Depending on display capability of LCD used, display will vary as shown below. xx contains the error number.

8-digit display 6-digit display 4-digit display

you can easily recall at any time. Here is a

list of the equalizer curves:

Display Equalizer curve

SBASS Super bass

PWRFL Powerful

NTRL Natural

VOCAL Vocal

CSTM Custom

FLAT Flat

• CSTM is an adjusted equalizer curve that

you create.

• When FLAT is selected no supplement or

correction is made to the sound. This is use-

ful to check the effect of the equalizer curves

by switching alternatively between

FLAT and

a set equalizer curve.

Press EQ to select the equalizer.

• If the equalizer has been previously set to

an equalizer curve other than PWRFL then

the title of that previously selected equalizer

curve will be displayed, such as SBASS,

the equalizer curve respectively.

• +6 – –6 is displayed as the equalizer curve

is increased or decreased.

• The actual range of the adjustments are

different depending on which equalizer

curve is selected.

Note

• If you make adjustments when a curve

other than CSTM is selected, the newly

adjusted curve will replace the previous

curve. Then a new curve with CSTM

appears on the display while selecting the

equalizer curve.
