WARNING
This product may contain a chemical known to the State of California to cause cancer, or birth defects or other reproductive
harm.
Health & Safety Code Section 25249.6 - Proposition 65
This service manual is intended for qualified service technicians; it is not meant for the casual do-ityourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained
to properly and safely repair complex products such as those covered by this manual.
Improperly performed repairs can adversely affect the safety and reliability of the product and may
void the warranty. If you are not qualified to perform the repair of this product properly and safely, you
should not risk trying to do so and refer the repair to a qualified service technician.
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 120 V
AC 60 Hz outlet and turn the AC power switch on. Any
current measured must not exceed 0.5 mA.
ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL
SHOCK HAZARD AND MUST BE CORRECTED BEFORE
RETURNING THE APPLIANCE TO THE CUSTOMER.
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 nominal
charge from PIONEER.

• 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.

This unit will automatically enter Demo mode if it is left unoperated for 10 minutes in Normal Operation mode, and a
demonstration with LED illumination will start.
To cancel this mode, operate any control or button of this unit.
To disable Demo mode, change the setting in the Utility settings. (For details, refer to the operating instructions.)
About Demo Mode
When replacement of the LED & COVER Assy is required, the Windows Lens must be detached, because the Windows Lens is attached to
the WHEEL Assy with double-back tape, which is attached around the outer periphery of the Windows Lens as a tube, and the LED & COVER
Assy is placed in between them.
Once the Windows Lens is detached, the double-back tape cannot be reused. The Windows Lens may not be reused either, because it may
be scratched, depending on the manner in which it was detached.
When replacement of the WHEEL Assy is required, the Windows Lens must also be detached and may not be reused.
Note that when replacement of the following Assys are required, replace them together with the parts mentioned below.
Double-back tape is supplied with the WHEEL Assy.
· When the LED & COVER Assy is to be replaced: Double-back tape (TWIN ADHESIVE) (must), Windows Lens (if necessary)
· When the WHEEL Assy is to be replaced: Windows Lens (if necessary)
(2) When replacing the LED & COVER Assy or WHEEL Assy of the JOG dial section
When the USB JACK in the DSP PCB Assy is to be replaced, the USB fixing bracket (USB fixed plate) must be detached
together with it. To detach them, remove the solder from the JACK and USB fixed plate.
For improvement of durability, the JACK and USB fixed plate were glued with adhesive for the products of the initial
production. (See the photo on the left below.)
In this case, replace the USB JACK together with the USB fixed plate.
The shape of the USB fixed plate has been modified so that it no longer requires adhesive for locking.
(See the photo on the right below.)
The USB fixed plate for service is the one after this modification.
The numbers of the products that have the older version of the USB fixed plate (fixed with adhesive) is as shown below:
DDJ-SX/UXECB: 2,000
DDJ-SX/SVYXE8: 418
DDJ-SX/FLPXE: 572

Will be tested fluctuation of voltage (A/D conversion value) which is made each Fader and Rotary volume by Master level
indicator.
[Overview]
Knobs under test operation are filled blue as below.
Test subjects to move by turning right / left-turn Rotary selector.
A/D conversion value observation start/reset by push the Rotary selector.
[Knobs under test operation]
1 Choose the test subject by turn left and right Rotary selector.
The LED is lit with the following turns every 1 click.
2 You can see what knob/fader is selected by Lighting LED on each button as shown in the above figure.
For example ,LED to test "SAMPLER VOLUME" fader is "MASTER CUE" button's LED.
3When targeted knob is decided, push the Rotary selector and start observation of A/D conversion value.
Get the A / D conversion value immediately after the start. It will be reference value.
*A/D conversion value to be monitored is Raw data.
4 Start monitoring and later to monitor the A/D conversion value, do the following actions depending on its value with
Master level indicator.
[Test detail]
• For failure judgment of the rotary VRs
As a guide, amplitude values higher than +4 or lower than -4 may be judged as failure.
The VRs can be set to any position during measurement. Possible symptoms are shown below.
• The volume changes arbitrarily.
• Interrupted sound leakage occurs even if the volume is decreased to the minimum at the Master or Booth Monitor.
• The MIDI signal is output even if the corresponding VR is not operated.
• For operation check of a rotary VR after replacement

5 By pushing the Rotary selector while monitoring the conversion value A/D, it is possible to reset the state of the fluctuations
of the past.
Ex.)
1. Turn EQ HI knob (for DECK 1) to the position you want to
measure.
7. More time has elapsed, Master level indicator is lit as
follows: become the value 758 of the A/D.
8. More time has elapsed, To maintain the above display
759 even though the value of the A/D.
9. More time has elapsed, Master level indicator is lit as
follows: become the value 757 of the A/D.
10. Off all the LED on Master level indicator When you push
the Rotary selector, and this value will be new reference
value.
2. Turned right 11 clicks Rotary selector.
→ "FX1 assign" LED of the DECK 1 is lit.
3. Start A/D conversion value monitoring to push Rotary
selector. If A/D value of push the Rotary selector is 760,
to monitor the amount of change in the value of A/D as
a reference value 760.
4. After a while, Master level indicator is lit as follows:
become the value 763 of the A/D.
5. More time has elapsed, to maintain the above display
762 even though the value of the A/D.
6. More time has elapsed, Master level indicator is lit as
follows: become the value 764 of the A/D.

NOTES: - Parts marked by “NSP” are generally unavailable because they are not in our Master Spare Parts List.
-
The > mark found on some component parts indicates the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of identical designation.
-
Although the cables that are directly mounted on each PCB Assy are listed individually as electrical parts of the
corresponding PCB Assy in the parts list, those cables are included with each PCB Assy for service when it is supplied.
