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. No differentiation is made between chip capacitors and discrete capacitors.

1) Precautions

• This unit uses a single power supply (+5V) for the regulator. The signal reference potential, therefore, is connected to REFO(approx. 2.5V) instead of GND. If REFO 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 REFO and GND together. It is especially important not to connect the channel 1 negative probe of the oscilloscope to REFO 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 REFO 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.

• Disc detection during loading and eject operations is performed by means of a photo transistor in this unit.Consequently, if the inside of the unit is exposed to a strong light source when the outer casing is removed for repairs or adjustment, the following malfunctions may occur.

*During PLAY, even if the eject button is

pressed,the disc will not be ejected and the unit will remain in the PLAY mode.

*The unit will not load a disc. When the unit malfunctions this way, either re-position the light source, move the unit or cover the photo transistor.

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).

• Jump operation of TRs other than 100TR continues after releasing the key. CRG move and 100TR jump operations are brought into the “Tracking close” status when the key is released.

• Powering Off/On resets the jump mode to “1TR”, and the automatic adjustment value to the initial value.

• Note : The grating angle of the PU unit cannot be adjusted after the PU unit is changed. The PU unit in the CD mechanism 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, REFOUT

• Disc • ABEX TCD-784

• Mode • TEST MODE

• Checking Procedure

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

2. Using the ] and [ buttons, move the PU unit to the innermost track.

3. Press key 3 to close focus, the display should read "91". Press key 2 to implement the tracking balance adjust-

ment the display should now read "81". Press key 3 2 times. The display will change, returning to "81" on the fourth press.

4. 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.

5. 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".

7. GENERAL INFORMATION

7.1 DIAGNOSIS

7.1.1 TEST 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.

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

ERROR–xx ERR–xx E–xx

Err–xx

(2) Error Code List

Code Class Displayed error code Description of the code and potential cause(s)

10 Electricity Carriage Home NG CRG can't be moved to inner diameter.

CRG can't be moved from inner diameter.

→ Failure on home switch or CRG move mechanism.

11 Electricity Focus Servo NG Focusing not available.

→ Stains on rear side of disc or excessive vibrations on REWRITABLE.

12 Electricity Spindle Lock NG Spindle not locked. Sub-code is strange (not readable).

→ Failure on spindle, stains or damages on disc, or excessive vibrations.

Subcode NG A disc not containing CD-R data is found. Turned over disc are found,

though rarely.

→ Failure on home switch or CRG move mechanism.

RF AMP NG An appropriate RF AMP gain can't be determined.

→ CD signal error.

17 Electricity Setup NG APC protection doesn't work. Focus can be easily lost.

→ Damages or stains on disc, or excessive vibrations.

30 Electricity Search Time Out Failed to reach target address.

→ CRG tracking error or damages on disc.

A0 System Power Supply NG Power (VD) is ground faulted.

→ Failure on SW transistor or power supply (failure on connector).

Remarks: Mechanical errors are not displayed (because a CD is turned off in these errors).

Unreadable TOC does not constitute an error. An intended operation continues in this case.

A newly designed head unit must conform to the example given above.

Upper digits of an error code are subdivided as shown below:

1x: Setup relevant errors, 3x: Search relevant errors, 3x: Search relevant errors, Ax: Other errors.

DEH-2350,1350

- New Test Mode

S-CD plays the same way as before.

If an error such as off focus, spindle unlocking, unreadable sub-code, or sound skipping occurs after setup, its

cause and time occurred (in absolute time) are displayed.

During setup, operational status of the control software (internal RAM: CPOINT) is displayed.

These displays and functions are prepared for enhancing aging in the servicing and efficiency of trouble analysis.

(1) Shifting to the New Test Mode

1 Turn on the current test mode by starting the reset from the key. 2 Select S-CD for the source through the specified procedure including use of the [SOURCE] key, and inserting the

disc. Then, press the [Jump Mode Selector] key while maintaining the regulator turned off.

3 After the above operations, the new test mode remains on irrespective of whether the S-CD is turned on or off.

You can reset the new test mode by turning on the reset start.

* With some products, the new test mode can be reset through the same operations as that employed for shifting to

the STBY mode (while maintaining the Acc turned off).
