IMPORTANT

THIS PION EER APPARATUS CON TA IN S LASER OF CLASS 1. SERVICING OPERATION OF THE APPARATUS SHOULD BE DON E BY A SPECIALLY INSTRUCTED PERSON.

Additional Laser Caution

1. Laser Interlock Mechanism The position of the switch (S9002) 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 test mode ∗ the interlock mechanism will not function. Laser diode oscillation will continue, if pin 5 (pin 3) of AN22022A (IC7002) on the SRVB Assy is connected to GND, or else the terminals of Q7002 (Q7001) 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.

For DVD Wave length (typ) : 655 nm Operation output : 3 mW CW, Class 1 Maximum output : Class 1 (Under fault condition) For CD Wave length (typ) : 790 nm Operation output : 4.5 mW CW, Class 1 Maximum output : Class 1 (Under fault condition)

• 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.

The part listed below is difficult to replace as a discrete component part. When the part listed in the table is defective, replace whole Assy.

JOG FL DEL1058

As the JOG FL is integrated with the FL Holder (DNF1735) with the aid of two pieces of double-back tape (Z12-016), first remove the integrated JOG FL and FL Holder, attach a new JOG FL and an FL Holder, using two pieces of double-back tape, then mount them together. (Note: As the integrated JOG FL and FL Holder are exactly the same parts as those for the CDJ-2000, you can handle them in the same manner as with the CDJ-2000.)

About the PNLB and CNCT Assys

The PNLB Assy and CNCT Assy are wired with jumper leads. The PNLB Assy (Part No. DWX3338) is supplied as a service part with the CNCT Assy connected. The CNCT Assy is not supplied individually as a service part.

About the Flash ROM (IC3) in the MAIN Assy

Replacement of the Flash ROM (IC3: DYW1814) in the MAIN Assy is not possible during service, because writing of the MAC address on the production line is required. Therefore, the Flash ROM (IC3) is not supplied as a service part. If the Flash ROM is defective, replace the whole MAIN Assy.

About work required after replacement of the Traverse Mechanism Assy (09SD)

After replacement of the traverse mechanism Assy (09SD), reset the LD lighting time to zero. How to Reset: See "7 Drive LD life reset" in "[3] Indication of various information" in "6.1 SERVICE MODE."

About transfer of the accumulated LD lighting time data after replacement of the MAIN Assy

This unit is equipped with self-diagnostic functions for the drives in Service mode. The service-life check for the laser diode (for CDs/DVDs) among the self-diagnostic functions uses the accumulated lighting time for judgment. If it is 7,000 hours or less, the laser diode is judged as OK. The accumulated lighting time of the LD is stored in the Flash ROM (IC3: DYW1814) in the MAIN Assy. Therefore, after replacement of the MAIN Assy, the accumulated lighting time of the LD is cleared and proper judgment will not be possible after that. To avoid such a situation, when replacement of the MAIN Assy is required, transfer the LD accumulated lighting time data. Before replacement, confirm the drive LD lighting time in Service mode and take note of the time value. After replacement is finished, enter Service mode then change the drive LD lighting time value to what you noted. For details on how to confirm and change the LD lighting time, see "8 Drive LD life manual input" in "[3] Indication of various information" in "6.1 SERVICE MODE."

About the self-diagnostic functions for the drives

This unit has self-diagnostic functions for the drives in Service mode. Use the self-diagnostic functions to check the drives if the problem symptom pointed out by the customer is a malfunction related to the drives or if a drive-related error is logged in the error history. For details on the self-diagnostic functions for the drives, see "[5] Drive Self-Diagnosis" and "[6] Contents of Drive Self-Diagnosis" in "6.1 SERVICE MODE."

About the iPod cable supplied with this unit

An iPod cable is supplied with this unit. Be sure to use the iPod cable supplied with this unit to connect an iPad with this unit in order to determine the cause of a charging problem with an iPad. Do not use the standard cable supplied with iPhones for this purpose, because it does not meet the specifications required for iPads (a voltage drop may result, because it is thin). The iPod cable supplied with this unit has been registered as service jig.

About backup of the UTILITY settings

As this unit is provided with user-settable UTILITY settings (such as the Play mode setting,) it is recommended that you back up the settings before starting repair. The settings can be stored for backup in a USB memory device or an SD card. For details on how to back up and restore data, see "g How to Back Up and Restore the Settings" in "8.5 ITEMS FOR WHICH USER SETTINGS ARE AVAILABLE ."

Measure the voltage at the probe pad on the SRVB Assy (see the photo below), using a tester. ∗ To check lighting of each LD, follow the procedure indicated in "[7] Checking the servo operations of the drive unit" in "6.1 SERVICE MODE." ∗ Note that the LD may be degraded if the probes of a tester are applied to or pulled away from the probe pad with the LD ON.

Check method

Directly measure the resistance value of the actuator, using a tester. * Before measuring, short-circuit the LD short-circuit pads. Note that the LD may be degraded if connection/disconnection of CN7001 is performed with the LD short-circuit pads open.

• Focus side Disconnect* the FFC connected to the CN7001 then measure the resistance value between FFC pins 23 and 24.

• Tracking side Disconnect* the FFC connected to the CN7001 then measure the resistance value between FFC pins 21 and 22.

Check method

1. With the LD OFF, apply the probes of a tester to the reference probe pad (LDCHK) and 78CHK (CD side) or 65CHK (DVD side).

2. With the probes kept applied to the above-mentioned pads, turn the LD ON to measure the voltage between them.

3. After measurement, turn the LD OFF (ALL OFF) then pull the probes away.

4. Calculate the current value by dividing the measured voltage value by the resistance value mentioned below. (For CDs: R7008 = 22 ohms, For DVDs: R7007 = 12 ohms)

Procedures

If the calculated current value exceeds the maximum value, the LD has been degraded

Failure judgment:

A value out of the range of the specifications is judged as failure.

In this section, causes of failure, diagnostics points, and corrective measures can be searched for according to symptoms. Before disassembling this unit, it is recommended to infer a failure point by performing a status check and referring to the error code. For the relationship of each power-supply and signal system, see “4. BLOCK DIAGRAM,” and “10. SCHEMATIC DIAGRAM.” If software of the product is updated before performing diagnostics, check that software updating has been performed properly before proceeding to diagnostics. If software updating has not been performed properly, update the software, following the instructions in [9] Firmware update of “6.1 SERVICE MODE.”
