1. SERVICE PRECAUTIONS
1.1 NOTES ON SOLDERING
1.2 SERVICE NOTICE
• 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.
Voltage Monitoring
This unit always monitors for power failure and will shut itself off immediately after an error is detected.
A power failure is indicated with flashing of the illumination LED of the channel fader for left side deck (deck A or C).
Other LEDs are unlit after an error is generated.
After the unit shuts itself off because of an error, disconnect the USB cable and wait at least 1 minute before
turning the unit back on.
Repair the unit according to the diagnostic procedures described in “5.3 VOLTAGE MONITORING.”
On Point-of-Sale Demo Mode
This product is provided with a Demo mode to be used when displayed on a stand in a shop.
Demonstrations with lighting of the LEDs on the control panel are automatically performed even if this product is connected
with a PC without the DJ application (VIRTUAL DJ LE) being started on the PC.
This mode will be established if no transmission or reception of MIDI signals is performed for 1 minute after the controller is
turned ON.
After VIRTUAL DJ LE is started, Normal Operation mode will be entered.
On the EEPROM on the IFPW ASSY
No program has been stored in the EEPROM (IC104) on the IFPWAssy (blank ROM) when it is supplied as a part for service.
After the EEPROM is replaced, be sure to copy the program for the USB controller to it. For details, see “8.2 HOWTO
PROGRAM COPY FOR USB CONTROLLER.”

3. BASIC ITEMS FOR SERVICE
3.1 CHECK POINTS AFTER SERVICING
3.2 JIGS LIST
Items to be checked after servicing
To keep the product quality after servicing, confirm recommended check points shown below.
No. Procedures Check points
1
Confirm that the customer complaint has been resolved.
If the problem pointed out by the customer occurs with a specific
source or operation, such as PC input, AUX/MIC input, Fader, or
Volume, input that specific source then perform that specific
operation for checking.
The customer complain must not be reappeared.
Audio and operations must be normal.
2Confirmation of operation of operating elements
Enter Service mode.
There must be no errors in operations of each button, Rotary
selector, Volume, Fader, Slider and JOG.

Set the POWER switch to OFF.
Check that the voltage of the V+VBUS
power line is in the range of 4.75–5.25 V.
If the voltage is outside the range of 4.75–5.25 V,
failure in the USB-bus power and its periphery
may be suspected. Check the USB cable and
USB connector.

HPLC Assy
Disconnect the cables from each Assy in
order to confirm which Assy’s power is
abnormal.
If the voltage returns to a normal level when the
cables from either the JACK Assy or HPJK Assy
are disconnected, the internal circuits of the
corresponding Assy may be defective. If the
voltage returns to a normal level when the cables
from the HPLC Assy are disconnected, either
the internal circuits of the HPLC Assy or the
circuit to which power is supplied from
V+5_HP_OUT inside the IFPWAssy may be
defective.
