• 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 SEEK UP and SEEK DOWN buttons, move the PU unit to the innermost track.

3. Press key 5 to close focus, the display should read "91". Press key 3 to implement the tracking balance
adjustment the display should now read "81". Press key 5 4 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
difference 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

- CD Test Mode

1) Precautions on Adjustment

• The unit employs a single voltage (+5V) for the
regulator, thus the reference potential of the signal is
RFOUT (approximately 2.5V) rather than GND.
Inadvertent contact of REFOUT and GND during
adjustment can result not only in disabling normal
potential measurement but also in exposing the
pickup to strong impacts due to malfunctioning of the
servo. Therefore, you are requested to observe the
following precautions.

• Make sure that the negative probe of the measuring
instrument is not connected to RFOUT or GND.
Special care must be exercised so that the channel 1
negative probe may not be connected to the
oscilloscope and the channel 2 negative probe to
GND. Since the frame of the measuring instrument is
usually at the same potential as the negative probe,
the frame of the measuring instrument must be
changed to floating status.
When RFOUT is inadvertently connected to GND, you
must immediately turn off the regulator or power
supply.

• The regulator must be turned off before mounting or
dismounting filters or wiring materials.

• You should not start adjustment or measurement
immediately after the regulator is turned on. It is
recommended to run the player for approximately
one minute so that it may stabilize.

• When the test mode is turned on, various protective
functions from the software become unavailable.
Thus, you must make sure that undesirable electric or
mechanical shocks are not be given to the system.

• This model employs a photo-transistor for detecting
discs at their loading or ejection. Thus, if its outer
case is removed during repair work and internal parts
are exposed to light of strong intensity, malfunctions
including the following can result:

∗ The eject button becomes inoperable during play.

Pressing the eject button does not eject a disc and
play is continued.

∗ Loading becomes unavailable.

If a malfunction is recognized, appropriate remedial
actions must be taken. Such actions include
changing the light source position, changing the unit
position and applying a cover to the photo-transistor.

• When you press the EJECT key to eject a disc, you
must not touch any other key until the ejection is
complete.

• If you press the TRACK UP or TRACK DOWN for the
focus search in the test mode, you must turn the
power off immediately. (Otherwise, the lens will be
forced to stick to the top or bottom, potentially
resulting in the burning of the actuator.)

2) Description of the Test Mode

• Turning on the Test Mode
See page 64.

• Ending the Test Mode
Apply the reset (the reset will be applied three
minutes after the power is turned from off).

• Operation of TR JUMPs (except 100TR) continues
after your finger has left the key. CRG, MOVE and
100TR JUMP are forced to the tracking close mode as
soon as the key is released.

• Turning the power on or off resets the JUMP MODE
to the Single TR.

Note 1:

Note 2:

The keys are inoperable as long as operation of the mechanism is continued.
When driving the CAMMOTOR in 31 → 30 → 10 (in REV direction),
the elevation position must be at the EJECT/LOAD position (the top position).

When the elevation is situated at the Note 1 position, move of any motor
other than the REV is disabled.
Before performing the elevation, make sure that the CAM SW (switch) is
set to a position between 22 and 20.
As a rule, driving of the ELV MOTOR must be started immediately after
the CAMSW indication has changed from 22 to 20.

Select CAMMOTOR using [3], then press the [TRACK DOWN] while the disc is being clamped (CAMSW state is 32).
The CAMSW status indication sequentially changes through 32→33→23→22.
When the disc to be ejected is not identical with the disc being clamped, select the [4 ] ELVMOTOR in the vicinity of where
the display changes from 22 to 20, then match the elevation to the disc to be ejected according to the following procedures:
After selecting ELVMOTOR, lower the elevation until the ELV position display becomes 01 (1st disc) using the [TRACK DOWN].
Drive the elevation up until the display is changed to 10 using the [TRACK UP] . This is the elevation where the second disk is situated.
The next display of 10 tells you the elevation of the 3rd disc. Repeating this operation allows you to establish an elevation
matching each disc. (When the elevation is driven from the 1st through 6th disc, the status display changes as
01→11→10→11→10→11→10→11→10→11→10.)
(When the disc to be ejected coincides with the disc being clamped, the above operations are not necessary.)
Select the [3] CAMMOTOR and then, using the [TRACK DOWN], drive it until the display changes from 20 (or 22) to 21 and 31.
Select the [4] ELVMOTOR, then drive the tray of the disc to be ejected up to the EJECT/LOAD position (using the [TRACK UP]).
Select the [6] CAM+LOADMOTOR, then drive it in the REV direction until the display changes from 31 to 30 and 10.
The door will open immediately before the display changes to 10 and part of the disc will be pushed out.
When 10 is displayed, select the [5] LOADMOTOR, then drive it in REV direction until the disc is completely ejected.

Exchange An error code indicating that exchange is judged to be necessary is entered.

Check An error code indicating that diagnosis is judged to be necessary is entered.

Unconnected Although registration is performed at ACC ON, there is no response when "Service Test" is started.

Old Ver Some error code is entered in the object old diagnostic Ver. equipment.

No Response Disconnection is occurring after "Service Test" has been started.

1 Equipment names Names are displayed including succeeding fitted components.
2 Test results Test results are displayed in the notation of "OK", "Check" and "Exchange".

* "Exchange", "Check" and "Old Ver" are displayed as switches, and "Communication

Diagnosis" and "Individual Diagnosis" are called according to the operation.

Calling the "Communication Diagnosis Detailed Information" or "Individual Diagnosis Detailed
Information" screen

• When test results are "Exchange", "Check" or "Old Ver", this display is used as a switch to switch to the detailed
display screen of "Communication Diagnosis" or "Individual Diagnosis" and to check the contents.

• If an "Individual Diagnosis" code is entered, the "Individual Diagnosis Detailed Information" screen is displayed.

• When an "Individual Diagnosis" code is not entered, the "Communication Diagnosis Detailed Information" screen is
displayed.
(Switching to both the detailed information screens is performed using the function key displayed on the screen.)

"Communication Diagnosis" detailed information screen

A "Communication Diagnosis" code is chosen and displayed in detail using the diagnostic code of the equipment
