- 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 con-

nector 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.

ANTENNAJACK

For resistors and capacitors in the circuit diagrams, their resistance values orcapacitance 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 indicatesthe importance of the safety factor of the part.Therefore, when replacing, be sure to use parts ofidentical designation.

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

NOTE :

Symbol indicates a capacitor.No differentiation is made between chip capacitors anddiscrete capacitors.

6. ADJUSTMENT

6.1 CD ADJUSTMENT

1) Precautions• This unit uses a single power supply (+5V) for the reg-

ulator. The signal reference potential, therefore, isconnected to VREF(approx. 2.1V) instead of GND.If VREF and GND are connected to each other by mis-take during adjustments, not only will it be impossi-ble to measure the potential correctly, but the servowill malfunction and a severe shock will be applied tothe pick-up. To avoid this, take special note of the fol-lowing.Do not connect the negative probe of the measuringequipment to VREF and GND together. It is especiallyimportant not to connect the channel 1 negativeprobe of the oscilloscope to VREF with the channel 2negative probe connected to GND.Since the frame of the measuring instrument is usual-ly at the same potential as the negative probe, changethe frame of the measuring instrument to floating sta-tus.If by accident VREF comes in contact with GND,immediately switch the regulator or power OFF.

• Always make sure the regulator is OFF when connect-ing and disconnecting the various filters and wiringrequired for measurements.

• Before proceeding to further adjustments and mea-surements after switching regulator ON, let the playerrun for about one minute to allow the circuits to stabi-lize.

• Since the protective systems in the unit's software arerendered inoperative in test mode, be very careful toavoid mechanical and /or electrical shocks to the sys-tem when making adjustment.

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

• This equipment will not guarantee the load ejectionoperation when the mechanical unit is turned upsidedown. In particular, if the ejection operation is incor-rectly performed and recovery is disabled, the recov-ery is enabled by resetting a product or turning ACCoff to on.

2) Test ModeThis mode is used for adjusting the CD mechanismmodule of the device.

• Test mode starting procedureReset while pressing the 4 and 6 keys together.

• Test mode cancellationSwitch ACC, back-up OFF.

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

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

• 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 adjustedPU unit for the CD mechanism module. Changing the PU unit is thus best considered as a last resort. However, ifthe 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 performtrack 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 Procedure1. 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 differ-

ence 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 themechanism should be judged to be at fault.

• NoteBecause of eccentricity in the disc and a slight misalignment of the clamping center the grating waveform may beseen to "wobble" ( the phase difference changes as the disc rotates). The angle specified above indicates the aver-age angle.

• HintReloading 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 (min-

utes 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.
