1. SAFETY INFORMATION

This service manual is intended for qualified service technicians ; it is not meant for the casual do-it­yourselfer. 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.

IMPORTANT
THIS PIONEER APPARATUS CONTAINS
LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUCTED PERSON.

LASER DIODE CHARACTERISTICS
FOR DVD : MAXIMUM OUTPUT POWER : 7 mw

FOR CD : MAXIMUM OUTPUT POWER : 5mW

WAVELENGTH : 650 nm

WAVELENGTH : 780 – 785 nm

Additional Laser Caution

1. Inside detection switch (S201 on the SMEB assy) and loading­status detection switch (S9503 on the MOT OR assy) are detected
by the microprocessor (IC501 in the DVDM assy).

• To permit the laser diode to oscillate, it is required to set the
inside detection switch for the inside position (S201 : ON) and to
set the loading-status detection switch for the clamp position (the
center terminal of S9503 is shorted to +5V). The 650 nm laser
diode for DVD oscillation will contin ue if pin 19 of IC101 is shorted
to +5V (fault condition) in the DVDM assy.
The 780 nm laser diode for CD oscillates if pin 20 of IC101 is
shorted to +5V in the DVDM assy.
In the test mode ∗ , the laser diode oscillates when microproces­sor detects a PLAY signal, or when the PLAY key is pressed
(S132 ON in the FLKB assy), with the above requirements satis­fied.

2. When the cover is open, close viewing through the objective lens
with the naked eye will cause exposure to the laser beam.

∗ : Refer to the service guide RRV2004.

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 × 10

47k Ω→47 × 103→ 473 ........................................................RD1/4PU 4 7 3 J

0.5 Ω→R50 .....................................................................................RN2H

1 Ω→1R0 ..................................................................................... RS1P

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

5.62k Ω→ 562 × 10

located on the player’s front panel. The remote control can be
used up to 7 m from the player and within a 30° angle each side of
the sensor.
¶ Exposing the remote sensor to direct sunlight or strong light

may cause faulty operation.
