2. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in the appliance
have special safety related characteristics. These are
often not evident from visual inspection nor the
protection afforded by them necessarily can be obtained
by using replacement components rated for voltage,
wattage, etc. Replacement parts which have these
special safety characteristics are identified in this
Service Manual.

Electrical components having such features are
identified by marking with a on the schematics and
on the parts list in this Service Manual.
The use of a substitute replacement component which
does not have the same safety characteristics as the
PIONEER recommended replacement one, shown in the
parts list in this Service Manual, may create shock, fire,
or other hazards.

Product Safety is continuously under review and new
instructions are issued from time to time. For the latest
information, always consult the current PIONEER
Service Manual. A subscription to, or additional copies
of, PIONEER Service Manual may be obtained at a

(FOR USA MODEL ONLY)

1. SAFETY PRECAUTIONS

The following check should be performed for the
continued protection of the customer and service
technician.

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground
(water pipe, conduit, etc.) by connecting a leakage
current tester such as Simpson Model 229-2 or
equivalent between the earth ground and all exposed
metal parts of the appliance (input/output terminals,
screwheads, metal overlays, control shaft, etc.). Plug
the AC line cord of the appliance directly into a 120V
AC 60 Hz outlet and turn the AC power switch on. Any
current measured must not exceed 0.5 mA.

LASER DIODE CHARACTERISTICS

FOR DVD : MAXIMUM OUTPUT POWER : 5 mW
WAVELENGTH : 650 nm
FOR CD : MAXIMUM OUTPUT POWER : 7 mW
WAVELENGTH : 780 nm

∗ : See page 160, 161, 164, 165.

1. Laser Interlock Mechanism
The position of the switch (S4400,S4500) for detecting loading

completion is detected by the system microprocessor, and the
design prevents laser diode oscillation when the switch is not
in LPS1 terminal side (when the mechanism is not clamped
and LPS1 signal is high level.)
Thus, the interlock will no longer function if the switch is
deliberately set to LPS1 terminal side. (if LPS1 signal is low
level ).
In the SERVICE MODE∗ the interlock mechanism will not
function.

Laser diode oscillation will continue, if pin 3 (pin 5) of

AN22022A (IC102, IC902) on the SRV1,SRV2 Assy is
connected to GND, or else the terminals of Q102
(Q103), Q902(Q903) are shorted to each other (fault
condition).

2. When the cover is opened, close viewing of the objective lens

with the naked eye will cause exposure to a Class 1 laser
beam.

WARNING !

THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1
BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR
CLASS 1.
A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS.

• For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs
accompanied by reworking of soldering.

• Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 ºC.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 ºC in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of
the soldering iron.

Do NOT use a soldering iron whose tip temperature cannot be controlled.

Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting
temperatures (hard to melt/easy to harden).

The following lead-free solders are available as service parts:

• Parts numbers of lead-free solder:
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.

How to apply FL OIL is described below.

Make sure that the top end of the load spring is not higher than that of the shaft when it is inserted into the shaft. If it is,
turn the JOG dial a little so that the load gear and the gear of the JOG shaft will become properly engaged.

<Preparation>
Soak FL OIL into a sponge.
Dab a brush against the sponge to pick up oil.
Remove excess oil from the brush.

<Application of FL OIL>

1. Dab the brush against the sponge to pick up a little
oil with the brush.

2. With the brush, lightly apply oil from the base to the
tip of the shaft.

3. Apply oil from 4 directions, as shown below, at a time.
(NEVER replenish oil to the brush on the way.)

<Note>

1. NEVER apply oil more than 4 times to the shaft.
Avoid applying excess oil.

<TOP VIEW>

Apply oil from the 4 directions
indicated by the arrows ( ),
at a time.

<SIDE VIEW>

Apply oil from the base to the
tip of the shaft, as indicated by
the arrows ( ).

NGOK

Place the JOG smoother so that its convex surface faces the JOG smoother plate.

Note on gear insertion

When inserting the gear, do NOT forcibly push it.
Insert the gear while turning it slightly until it is properly
engaged.

After the JOG Assy is disassembled or JOG dial parts are replaced, be sure to measure the load on the JOG dial, as it may
have changed. (For details on how to measure the load on the JOG dial,
see “8.1 CONFIRMATION MODE AND ADJUSTMENT METHOD FOR LOAD ON THE JOG DIAL.”)

TYPES OF DISCS PLAYABLE ON THIS UNIT

• Playable discs will display one of the following logo marks on the disc label, packaging, or jacket:

About disc playback

This unit can play CD-R/CD-RW discs recorded in music CD (CD­DA) or CD graphics (CD-G) format, and CD-R/-RW, DVD-R/-RW,
DVD+R/+RW, and DVD±R dual layer discs recorded in MP3/AAC
file format.

The following discs cannot be played on this unit

CDs: DTS-CDs, photo-CDs, video-CDs, and unfinalized CDs
DVDs: DVD video, DVD audio, DVD-RAM, unfinalized DVDs, MPEG

moving picture files

Backup your discs!

Due to structural characteristics of CD-R/-RW, DVD-R/-RW,
DVD+R/+RW, and DVD±R dual layer media, if such discs are left
for extended periods in the pause (or cue standby) mode, they
become unplayable or difficult to play at that point on the disc. The
same symptom may occur if the loop function is used to repeat the
same section of a disc for an extremely large number of times.

When using discs holding important files or tracks, always make
backups first.

About copy-control CDs

This unit is designed to comply with music CD standards. We

cannot guarantee operation or performance when using discs that

do not comply with these standards.

[DualDisc] playback

This unit is designed to comply with music CD standards. We
cannot guarantee operation or performance when using discs that
do not comply with these standards.

About 8 cm single CDs

8 cm single CDs cannot be played on this unit. Also, do not
attempt to attach an 8 cm adapter to a disc and play it in this unit,
since the adapter may become detached during playback, causing
damage to the disc or player.

About CD-TEXT on music CDs

This unit supports CD-TEXT, and displays track titles, album titles,
and artist names recorded in CD-TEXT. Supported character codes
include ASCII, ISO-8859, MS-JIS, and Mandarin Chinese. When
multiple text data are recorded, the first text data is displayed.

NOTE

• CD-R/-RW, DVD-R/-RW, DVD+R/+RW, and DVD±R dual
layer discs recorded on a standalone recorder or computer
may not play properly on this unit for a variety of reasons,
including individual characte ristics of the disc, scratches
or soiling of the disc, or dirt or condensation on the player’s
laser lens.

• Discs recorded on a computer’s disc drive may not play
properly due to variations in the recording software settings
or computer environment. Besure to record discs in the
proper format (for details, consult the distributor of the
recording software application).

• For detailed information regarding the handling and use of
your disc media, consult the precautions and instructions
furnished with the discs.

• When connecting a USB storage device containing a large number of folders and files, some time may be required to read

in the device contents.

• When a connected USB storage device contains multiple partitions, only the initial partition can be used.

CAUTION

Depending on the device used, proper playback may not be possible with all USB storage devices.
Pioneer assumes no responsibility for any loss of data resulting from connecting any given USB device to this
unit.

• Proper operation may not be possible when a USB storage device is connected through a USB hub.

• Even if a USB hub is used to connect multiple USB storage devices, the second and later devices cannot be used.

• Operation cannot be guaranteed when using a USB storage device with installed flash card reader.

• When connecting a USB storage device utilizing two USB cables, connect both cables to this unit’s USB ports.

• If an electrical current stronger than the allowable current is applied to the unit’s USB1 port or USB2 port, the unit may stop

supplying power to the USB storage device, thus terminating transmission. In this case, a message will be displayed in the
center display of the unit, and the stop indicators for USB1 and USB2 will flash red simultaneously. To restore normal
operation, disconnect all USB storage devices connected to the unit, then hold either of the USB STOP buttons depressed
for two seconds or more. Avoid connecting the USB storage device from which the excess current was detected and other
USB storage devices connected through a bus-powered USB hub. If normal operation is not restored through this method,
turn the power of this unit off, and then turn it back on.

CAUTION

When disconnecting a USB storage device, always be sure to perform the STOP operation first. If the STOP
operation is not completed before disconnection, cue/loop memory and playlist update may not occur properly,
resulting in the loss of data. Also, the USB storage device may becomes unreadable, or other substantial damage
may occur. Always disconnect the USB storage device before turning off the power to this unit.

Normal Style mode:
The MEP-7000 (Control Unit and Drive Unit) is connected.

Manipulator Style mode:
The SEP-C1 (only the Control Unit) is connected.

You can check if communication via USB ports is properly performed between the PC that is connected via the PC connec­tor of this unit and this unit in two ways: The PC connector via which the PC is connected is the one on the Drive Unit if you
are using Normal Style mode, and it is the one on the Control Unit if you are using Manipulator Style mode. Before connect­ing the PC to this unit, the dedicated driver software (with the utility program for version indication) must be installed on the
PC. For details on how to install it, refer to “About the Driver Software” in the Operation Manual of the MEP-7000.

Confirmation with the utility program for version indication

If the driver software is installed properly on the PC, the utility program for version indication becomes operable. While you
install the driver software (referring to “About the Driver Software” in the Operation Manual of the MEP-7000) if the firmware
version is displayed in the dialog box, that signifies that the PC and this unit are communicating properly via USB.

Confirmation with the Device Manager

After the driver software has been properly installed on the PC and this unit is connected to the PC, the devices that are
framed in the figures below will be added to the list of hardware in the Device Manager. If all the indicated devices are
displayed properly, that signifies that the PC and this unit are communicating properly via USB.

In this troubleshooting section, causes and defective points can be searched for from symptoms.
It is recommended to perform auto device diagnosis and to check the status LEDs and error codes
before disassembling the product, in order to infer failure points.

See “[3] POWER DELIVERY” in “4.3 BLOCK DIAGRAM” for details on the power supply system of each block.

For details on the waveforms whose numbers are described in this section, see “10.29 WAVEFORMS,”
where detailed information such as the points at which to measure waveforms is described
(the same waveform numbers are used in “10 SCHEMATIC DIAGRAM” and “11 PCB CONNECTION DIAGRAM”).

There are 2 play styles, according to how the product is used.
Depending on the play style, items to be checked for the control unit differ.

1. Normal Style (Control Unit + Drive Unit)

2. Manipulator Style (Control Unit + PC)
For details on the play styles, refer to the operation manual of the MEP-7000.

*1

PRO DJ screen

If operation stops at the point at which the PRO DJ logo*1 is displayed in Normal Style mode, communication between the
control and drive units has not been established.
Upon startup, a signal is output from the North CPU (IC601) of the control unit to the FPGA (IC301) of the drive unit, then
returned from the FPGA to the North CPU to establish communication.

Has the updating of the firmware
for the drive unit failed?

Check the defective point with the
Status LEDs on the SMAIN Assy.

Check if the FFC cables that
connect the SMAIN and SJACK
Assys are securely connected
and if there is breakage in the
FFC cables.

Check the waveforms of the
signals shown below that are
output from the SJACK Assy to
the FPGA (IC301) on the SMAIN
Assy in order to confirm in which
point communication is
interrupted.
From the control unit to the
drive unit:

• BRDG_CLK

• BRDG_FS

• BRDG_CS#

• KEY_DATA
From the drive unit to the
control unit:

• DISP ASSY_DATA1

• DISP ASSY_DATA2

If updating failed, operation stops at the point
at which the PRO DJ logo is displayed after
startup, and the LED for the USB STOP key
flashes repeatedly.
See [4] in “8.3 UPDATING/RECOVERY OF
FIRMWARE.”

If any point is judged as NG,
see “[8] Auto Device Diagnosis/Status LEDs” in
this section.
If the Status LEDs flash continuously, go to [4].

If a connection is loose, firmly connect the
cable.
If there is breakage, replace the cable.

If a signal sent from the control unit to the drive
unit is not input to the JA13 jack on the SJACK
Assy either, the control unit may be defective.
Go to [6].
Check the input/output signals to/from the
buffer ICs (IC303 and IC306) on the SMAIN
Assy. If no signal is output even if there is an
input signal, the ICs may be defective or
improperly mounted. Resolder the ICs, and if it
does not resolve the problem, replace the ICs.
If no signal is input to the buffer ICs (IC303 and
IC306), connection between the SJACK and
SMAIN Assys is poor. Resolder the corre­sponding ICs.

The unit starts up normally but freezes up after a short time.

Check that the signals mentioned
in [4]
are input or output to/from the
FPGA (IC301).

Check if the cables that connect
the DJACK and NJACK Assys
and NMAIN and NJACK Assys
are securely connected and if
there is breakage in the cables.

Check the waveforms of the
signals shown below that are
output from the NORTH CPU
(IC601) to JA2400 on the DJACK
Assy in order to confirm in which
point communication is
interrupted.
From the control unit to the drive
unit:

• BRDG_CLK

• BRDG_FS

• BRDG_CS#

• KEY_DATA
From the drive unit to the control
unit:

• DISP ASSY_DATA1

• DISP ASSY_DATA2

If no signal is output even if there is an input
signal,check the mounting status of the FPGA
(IC301).
If it is properly mounted, the port connector
may bedefective; replace it.
If no signal is input in the first place, connec­tion is poor.
Resolder the connectors.

If a connection is loose, firmly connect the
cables.
If there is breakage, replace the cable.

Check the input/output signals to/from the
buffer IC on the NJACK Assy. If no signal is
output even if there is an input signal, check
the mounting status of the IC. If the IC is
properly mounted, it is defective; replace the
IC.
If no signal is output from the NORTH CPU
(IC601)
either, check the mounting status of the IC. If
the IC is properly mounted, the port connector
is defective;
replace it.

Check if the FFC cables that
connect the SMAIN and SRV 1/2
Assys are securely connected
and if there is breakage in the
FFC cables.

If a connection is loose, firmly connect the
cable.

[4] LD (Laser Diode) Status

The degree of degradation of the laser diode (LD) mounted on the Traverse mechanism (TM) of the DVD/CD drive
can be measured using change in the current value and accumulated time of light emission (LD degradation diagnosis).
The result of diagnosis from a viewpoint of the LD current value is used for defect judgment of the Pickup Assy.
See “5.4 DEFECT JUDGMENT OF THE PICKUP ASSY.”

Diagnosis from a viewpoint
of the LD current value

Diagnosis from a viewpoint
of the accumulated time
of light emission

The LD current value at the factory (INITIAL VALUE) and accumulated time of LD light emission are stored
in the main flash memory (SMAIN) of the drive unit.

INITIAL VALUE

CURRENT VALUE

The LD current value that was written at the product
inspection line at the factory is displayed as the initial
value for this unit. Or, an LD current value that was
rewritten in the past, following the procedures described
in “8.2 RESET OF DVD/CD DRIVE DATA ,” is displayed.

The LD current value is automatically measured each
time this unit is turned on. The measured value is
displayed as the “CURRENT VALUE.”
(This value will not be written to memory.)

0000~9999 Current (mA)

If the ambient (environmental) temperature has been high, or if damaged or dirty
discs have been used for an extended period of time, the LD may be damaged. In
such a case, the LD current value will change from the one that was stored in
memory at the factory for the first time. Using this mode, an approximate degree of
degradation of the LD can be judged.
*How to proceed with degradation diagnosis with the LD current value is described
separately.

When discs in good condition are played back with this unit under ambient
(environmental) temperature of 35 , the LD has a service life of 7,000 hours.
Even if the usage time exceeds 7,000 hours, it is not required to replace the LD if
the above-mentioned LD current value is normal.

Note: If the SMAIN Assy on which the data on the TM (initial value of the LD current and accumulated time of

LD light emission) have been recorded is replaced, refer to “8.4 MANUAL INPUT OF DVD/CD DRIVE DATA.”

Note: If the TM is replaced, the data on the new TM must be written to the SMAIN Assy of this unit.

For details on how to write the data, see “8.2 RESET OF DVD/CD DRIVE DATA.”

By using the test-pattern data stored in the main flash memory (NMAIN) of the control unit or video encoder, a check of the
output signals to the center display (LCD) and a monitor connected via MONITOR OUT of this unit can be performed.
Checking of the center display for lit and dark cells and dirt can also be performed.

If an image is disturbed or no video signal is output, by switching between the Function 1 and 2 keys, a defective point
on the image process path can be identified.
