and mayvoid the warranty. If you are not qualified to perform the repair of this product properly and
safely, youshould not risk trying to do so and refer the repair to a qualified service technician.
WARNING !
THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1
BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR
CLASS 1.
A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS.
B
LASER DIODE CHARACTERISTICS
FOR DVD : MAXIMUM OUTPUT POWER : 5 mW
WAVELENGTH : 650 nm
FOR CD : MAXIMUM OUTPUT POWER : 5 mW
WAVELENGTH : 780 nm

1. Laser Interlock Mechanism
• Loading switch (S101 on the LOAB Assy) is used for interlock
mechanism of the laser.
When this switch turned ON in SW2 (CLOSE) side (OPEN signal is
0V and CLOSE signal is 3.5V), a laser becomes the status which can
completely oscillation.
Furthermore, the laser completely oscillates in the disc judgment and
disc playback.
When player is power ON state and laser diode is not completely
oscillating, 780nm laser diode is always oscillating by half power.
• Laser diode is driving with Q7 (650nm LD) and Q8 (780nm LD)
on the DVDM Assy.
Therefore, when short-circuit between the emitter and collector of these
transistors or the base voltage is supplied for transistors turn on, the
laser oscillates. (failure mode)
• In the test mode ∗ , there is the mode that the laser oscillates except
for the disc judgment and playback. LD ON mode in the test mode
oscillates with the laser forcibly.
The interlock mechanism mentioned above becomes invalid in this
mode.
2. When the cover is open, close viewing through the objective lens with
the naked eye will cause exposure to the laser beam.

5. PCB PARTS LIST
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.
When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).
560 Ω
56 x 10 1
RD1/4PU 5 6 1 J
561
47k Ω
RD1/4PU 4 7 3 J
47 x 10 3
473
0.5 Ω
RN2H R 5 0 K
R50

Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

• Calculation of the average error rate (ESC + "5" [Test mode remote control unit] keys)
The average of the last eight error rates is calculated and indicated in exponential notation. After the calculation is completed, "OK" or "NG" is
displayed. If "NG" is displayed, the disc tray will open (for both DVDs and CDs)
For DVDs: OK with 5.0e-4 or less, for CDs: OK with 7.6e-3 or less
• Indication of model information (ESC + CHAP keys)
The items from 12 to 15 of the TEST MODE Indications are displayed. However, in the indications, S in the standard test mode is changed to
CHIP VERSION, and M is changed to RF VERSION. For details, see 7.1.4.

7.1.6 METHOD FOR DIAGNOSING DEGRADATION OF THE LDS ON THE PICKUP ASSY
Case when this diagnosis is required :
When playback of any disc, including a test disc (DVD: GGV1025, CD: STD-905), cannot be performed
A
How to diagnose
In the case mentioned above, degradation of the laser diodes (LDs) mounted on the 03 SD Pickup Assy-S is suspected.
Measure the voltage between the two ends of one of the resistors mentioned below.
No playback of a DVD :
Measure the voltage between the two ends of R22 or R25 on the DVDM Assy.
If the voltage is 0.4 V or higher, the 650-nm LD is degraded.
If the measurements show degradation
of an LD, replace the 03 SD Pickup
Assy-S.
No playback of a CD :
Measure the voltage between the two ends of R21 or R26 on the DVDM Assy.
If the voltage is 0.4 V or higher, the 780-nm LD is degraded.

7.1.8 ID NUMBER AND ID DATA SETTING
Caution:
For the DVD players compatible with DVD-RW, for playback of a DVD-RW disc (CPRM), it is necessary that an individual ID
number and ID data are set for each player. If the ID number and ID data be not properly set in the manner described below,
future operations cannot be guaranteed. The ID number is written on the yellow label at the rear panel of the player.
If there is no yellow label, before downloading FLASH ROM, take note of the ID number set following the procedures
outlined in "ID Number Confirmation Mode" on the next page.
A
Note: Enter ID numbers while the unit is in Stop mode so that the values set will be immediately written to the flash ROM.
Setting an ID number or ID data is required in the
following case:
If "No ID Number!" or "NO ID DATA!" is displayed on the
TV screen and on the FL display for a few seconds
immediately after the power to the player is turned on or
during Stop mode.
5 After entering all 9 digits, if you press the SEARCH key, the
unit unconditionally sets the input number as the ID number.
Then the unit automatically enters Player's Data Input Mode.
(The SEARCH key is not accepted after all 9 digits have been
entered.)

unit returns to Step 2 without doing anything else. Each press
of this key after a number has been input deletes one digit.
Note: If a previous ID number and ID data, such as a factorypreset ID number and ID data, are maintained, the unit
enters ID Number Confirmation Mode when the above keys
are pressed. However, if only an ID number is maintained,
the unit enters ID Data Input Mode.
