SYSTEM CONTROLLER
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.

1) Precautions• This unit uses a single power supply (+5V) for the reg-
ulator. The signal reference potential, therefore, isconnected to REFO(approx. 2.5V) instead of GND.If REFO 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 REFO and GND together. It is especiallyimportant not to connect the channel 1 negativeprobe of the oscilloscope to REFO 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 REFO 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.
• Disc detection during loading and eject operations isperformed by means of a photo transistor in thisunit.Consequently, if the inside of the unit is exposedto a strong light source when the outer casing isremoved for repairs or adjustment, the following mal-functions may occur.
*During PLAY, even if the eject button ispressed,the disc will not be ejected and the unitwill remain in the PLAY mode.
*The unit will not load a disc.When the unit malfunctions this way, either re-posi-tion the light source, move the unit or cover the phototransistor.
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).
• Jump operation of TRs other than 100TR continuesafter releasing the key. CRG move and 100TR jumpoperations are brought into the “Tracking close” sta-tus when the key is released.
• Powering Off/On resets the jump mode to “1TR”, andthe 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 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, REFOUT• Disc • ABEX TCD-784• Mode • TEST MODE
• Checking Procedure1. 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 thefourth 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 anyimprovement. 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".

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
OR
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.

- 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).
