SAFETY INFORMATION
IMPORTANT
THIS PIONEER APPARATUS CONTAINS
LASER OF CLASS 1.
SERVICING OPERATIONOF THE APPARATUS
SHOULD BE DONE 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)

1.3 SERVICE NOTICE
About the Flash ROM (IC12) and USB-LAN Conversion IC (IC602) in the MAIN Assy
Replacement of the Flash ROM (IC12) and USB-LANConversion IC (IC602) in the MAINAssy is not possible during service,
because writing of the MAC address on the production line is required and USB-LANConversion IC (IC602) has unique ID.
Therefore, the Flash ROM (IC12) and USB-LANConversion IC (IC602) are not supplied as a service part.
If the Flash ROM and USB-LANConversion IC are defective, replace the whole MAINAssy.
After replacing the the MAINAssy, writing of the serial number of the unit is required.
For details on how to write the serial number, see "8.3 WRITING THE SERIAL NUMBER OF THE UNIT."
About work required after replacement of the TM Assy 09SD-S
After replacement of the TM Assy 09SD-S, reset the LD lighting time to zero.
How to Reset: See "6Drive LD life manual input" in "[3] Various displayed 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
(IC12) in the MAINAssy. Therefore, after replacement of the MAINAssy, 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
MAINAssy 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 "6Drive LD life manual input" in "[3] Various displayed
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."
Before starting servicing
For prevention of electrical shock, before starting working on the product, be sure to wait at least 2 minutes after unplugging
the Power cord.
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 "gHow to Back Up and Restore the Settings" in "8.6 ITEMS FOR WHICH
USER SETTINGS ARE AVAILABLE."

SW POWER SUPPLY Assy Primary side electrical shock
The primary side of SW POWER SUPPLY Assy remains voltage long time, and the primary solder side can be seen.
So if you touch the primary solder side, it is possible to receive an electrical shock.
There is the red area below where we tend to receive an electrical shock.
Be sure to dischsarge the voltage of primary side to avoid receiving the electrical shock.
When discharging the above point, use the following discharge jig as needed.
While the charging voltage is left of both C4 and C5, either of checking LEDs turns on.
And if both of LED turns off, we can avoid receiving the electrical shock!!
When there is no above type LED, take measures the following method.
Step 1: After the power is turned off, wait 2 minutes.
Step 2: Connect the Register Jig and leave the unit as it is, for 10 seconds.
• Resister is all 10 kΩ(3W)
• Both of LED is LTL17KRH5D

5.2 FAILURE JUDGEMENT OF THE PICKUP ASSY
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 ONto 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.

Service mode.
See the section describing locations of defects in
this manual.
6.1 SERVICE MODE
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."
