• 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 SEEK UP or SEEK 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 83.

• Ending the Test Mode
Apply the reset (the reset will be applied two 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.

No sound is reproduced even if Tracking Closes, because the
STS IC is not controlled during the test mode.

•

•

•

For all TR jumps (except for 100TR jump), the track jump operation continues even after the key is
released. For the CRG Move and 100TR jump, the tracking closes at the same time when the key is released.
With the Power Off/On, the Jump Mode is reset to the Single TR(91).
To exit from the test mode, reset the unit. (All modes are completely reset about 2 minutes after the Power is turned off.)

Note:

• If [SEEK UP] or [SEEK DOWN] key is pressed during Focus search, turn off the power
immediately to prevent the actuator's damage caused by the lens stuck.

During the mech operation, each key input is ignored.
When the ELV position is '11'(*Note 1), the other motors cannot be moved.
For elevation, the CAMSW should be at the state *Note 2 as shown above.
Basically, right after the display for the CAM SW changes from 22 to 20, drive the ELV MOTOR.)
When the CAM MOTOR is moved in the REV mode (31 → 30 → 10),
the Elevation should be at the EJECT/LOAD position.

Press the [3] key to select the CAM MOTOR, and drive the CAM MOTOR from the CLAMP position (CAMSW:32) for the REV direction.
The CAMSW display changes as 32→33→23→22.
If the disc clamped is not the disc to be ejected, around the shifting point between 22 and 20,
press the [4] key to select the ELV MOTOR and to position the elevation to the disc to be ejected.
After selecting the ELV MOTOR, first be sure to move the Elevation down (in the REV direction) till the ELV position display shows 01 (Disc 1).
When the Elevation is moved upward (in the FWD direction), the first indication of 10 shows the position of Disc 2, and the second indication
of 10 shows that of Disc 3.
Therefore, you can detect the position of the elevation by counting the number of the indication '10'.
(Ex: When the elevation moves from Disc 1 to Disc 6, the display changes as follows:01→11→10→11→10→11→10→11→10→11→10.)
(If the disc to be ejected has been clamped, step 2 is not necessary.)
Press the [3] key to select the CAM MOTOR, drive the CAM MOTOR in the REV direction till the indication changes from 20 (or 22)
to the shifting point between 21 and 31.
Press the [4] key to select the ELV MOTOR, and move the tray for the disc to be ejected to the EJECT/LOAD position (in the FWD direction).
(When the elevation is positioned at the top after moving in the FWD direction (the indication: 10), this is called the EJECT/LOAD position.)
Press the [6] key to select the CAM+LOAD MOTORS, and move the motor in the REV direction until the display changes from 31 to the
shifting point between 30 and 10.
When the display becomes 10, the door opens and the disc is slightly pushed out.
When the display becomes 10, press the [5] key to select the LOAD MOTOR. Drive the motor in the REV direction to eject the disc completely.
