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-it- yourselfer. 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.

• 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.

• For checking of audio and operating elements, the DJ application (TRAKTOR) included with this product is used. TRAKTOR must be installed in your PC. For details on installation, see "5.4 HOW TO CHECK OPERATIONS USING THE TRAKTOR SOFTWARE." For connection of this product with a PC, be sure to use the supplied USB cable (registered jig tool), whose operation with this product is guaranteed.

Voltage Monitoring

This unit always monitors for power failure and will shut itself off immediately after an error is detected. All LEDs are unlit after an error is generated. After the unit shuts itself off because of an error, disconnect the AC adapter and 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.”

Limitations when the unit is operating on USB-bus power

There are some limitations in operations of this unit while it is operated on USB-bus power, as shown below.

• The JOG dial indicator does not light.

• Lighting of the indicators (excluding that for the JOG dial) becomes dim.

• The AUX IN and MIC connectors are disabled.

• The sound volume through the headphones is reduced.

On the EEPROM on the UCOM ASSY

No program has been stored in the EEPROM (IC2003) on the UCOM Assy (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 “8.4 Copying the Program for the USB Controller.”

Replacement of the MAIN_UCOM

When replacement of the MAIN_UCOM (IC701) is required, order a microcomputer dedicated for service (PEG850A8-K).

Loose connection /defective parts

UCOM Assy

Check that the audio signal is input to the ADC (IC303).

• If an audio signal is output, go to [3].

• If an audio signal is not output, go to [5].

3 UCOM Assy

Check the digital input signals to ADC (IC303).

• ADC_RST (IC303-13 pin)

• MIC_AUX_DATA (IC303-1,2 pins)

If the level of ADC_RST is L, check the connections of the MAIN_UCOM (IC701). If nothing is wrong with the connections, then the MAIN_UCOM (IC701) itself may be defective. If the MIC_AUX_DATA signal is not input, check the connections. If nothing is wrong with the connections, then the ADC (IC303) may be defective.

4 UCOM Assy

Check the connections of the USB_UCOM (IC202).

If nothing is wrong with the connections, then soldering of the USB_UCOM (IC202) or the USB_UCOM itself may be defective.

5 UCOM Assy

Check that the AIN_MUTE signal level is L (muting canceled).

If it is not L (muting canceled,) check Q509. If the symptom persists, soldering of the MAIN_UCOM (IC701) or the MAIN_UCOM itself is defective.

6 UCOM Assy

Check the connections between the SW AMP (IC301/IC302) and ADC (IC303) of the MAIN.

If the connections are properly made, soldering of the SW AMP (IC301/IC302) or the SW AMP itself is defective.

7 JACB Assy

Check that an audio signal is input to Pins 4 and 6 of the CN4402.

If a signal is input, go to [9]. If a signal is not input, identify the point where the audio signal is interrupted on the line from the AUX terminal (JA4401) to the CN4402. If an audio signal is interrupted at the periphery of the OP amp (IC4401/IC4402), soldering of the OP amp or the OP amp itself may be defective.

8 MICB Assy

Check that an audio signal is input to Pin 4 of the CN4601.

If a signal is input, go to [9]. If a signal is not input, identify the point where the audio signal is interrupted on the line from the MIC terminal (JA4601) to the CN4601. If an audio signal is interrupted at the periphery of the OP amp (IC4601), soldering of the OP amp or the OP amp itself may be defective.

9 UCOM Assy

Check the connections between CN302 (AUX)/CN303 (MIC) and SW AMP (IC301 /IC302).

If the connection is improperly made, correct it.

10 UCOM Assy

Check AUX_MIC_SEL.

• When AUX is selected: “H”

• When MIC is selected: “L”

If it is not, check Q301. If the symptom persists, soldering of the MAIN_UCOM (IC701) or the MAIN_ UCOM itself is defective.

No.

[7] Basic Operation Check of the MAIN_UCOM

Note: First, check if the voltage at each section is OK.

GRID Operation Check (No operation with keys, VRs, sliders, or LEDs)

UCOM Assy

Check the power to and the input/output waveforms of the GRID IC (IC702)

If the waveform is not proper, check the GRID line and the parts, such as resistors and capacitors. If the output waveform is not proper, check item [2]. If nothing is wrong with the parts, the GRID IC (IC702) or the MAIN_UCOM (IC701) may be defective.

2

UCOM Assy Assy corresponding to each key

Check the output waveform of the GRID IC (IC702), with the FFC cable of the UCOM Assy disconnected.

If the waveform returns to normal, the PCB Assy that is connected with the UCOM Assy via the FFC cable may be defective. If the waveform does not return to normal, the GRID IC (IC702) may be defective.

3

KEY Buffer operation (key input disabled)

UCOM Assy

Check the power supply to the KEY Buffer ICs (IC1101 and 1102) and the input/output waveforms when a key is pressed.

If the input waveform appears but the output waveform does not when a corresponding key is pressed, the KEY Buffer ICs (IC1101 and 1102) may be defective. If the input waveform does not appear when a corresponding key is pressed, check item [4].

No operation button is effective.

4

UCOM Assy Assy corresponding to each key

Check the connection of the FFC cable. Check also the key input circuit of the PCB Assy connected.

If the key input circuit of the board connected is normal, the KEY Buffer ICs (IC1101 and 1102) may be defective.
