- CD Player Service Precautions
1. For pickup unit(CXX1311) handling, please refer
to"Disassembly"(see page 55).
During replacement, handling precautions shall be
taken to prevent an electrostatic discharge(protection
by a short pin).
2. During disassembly, be sure to turn the power off
since an internal IC might be destroyed when a connector is plugged or unplugged.
3. Please checking the grating after changing the service pickup unit(see page 46).
- When the Repair is Complete
When the repair is complete, make the CD mechanism
ready for transportation
implementing the following procedures:
1. Press the changer side 1 and 4 simultaneously to turn
the ACC on.
2. As the ACC is turned on, the disc indicator blinks in
red.
3. When the blinking is stopped, the mechanism is
ready for the transportation.
4. Attach the Transportation Bracket (CNC7878). Now
you can transport it.(See the figure below) (The
Bracket used on the CDX-PD6/UC is recommended
for the transportation purpose.)

• 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 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 TRK+ and TRK- buttons, move the PU unit to the innermost track.
3. Press key F9 to close focus, the display should read "91". Press key F8 to implement the tracking balance adjustment the display should now read "81". Press key F9 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 photot-ransistor 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 TRK+ or TRK– 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
Adjustment of this unit is done in parallel with the CD
control unit (KEH-P7000 or a head unit conforming to
the IP-BUS specifications), thus key operations for
adjustments are done from the unit. Taking the
example of the KEH-P7000, the following describes
how to turn on the test mode and operate the keys.
The keys referred to in the following are those used
on the KEH-P7000.
• Turning on the Test Mode
Press the [4] and [6] keys simultaneously to turn on
the ACC and the backup.
• 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.

Select CAMMOTOR using [F.7], then press the [TRK–] 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 [F.8] 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 [TRK-].
Drive the elevation up until the display is changed to 10. 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
