1. SAFETY INFORMATION
(Printed on the Rear Panel)
LABEL CHECK
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.
LASER DIODE CHARACTERISTICS
FOR DVD : MAXIMUM OUTPUT POWER : 5 mW
WAVELENGTH : 655 nm
FOR CD :
MAXIMUM OUTPUT POWER : 5 mW
WAVELENGTH : 785 nm
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.
Additional Laser Caution
1. Loading-status detection switch (S101 on the LOAB assy) are detected
by the microprocessor (IC601 in the DVDM assy).
• To permit the laser diode to oscillate, it is required to set the loading-
status detection switch for the clamp position (the center terminal of S101
is shorted to +3V).
When the voltage of IC101-pin 20 is +3V and IC601 (microprocessor) -
pin 83 is +3V, 650nm laser diode for DVD oscillates in the DVDM Assy.
When the voltage of IC101-pin 20 is +3V and IC601 (microprocessor) -
pin 83 is 0V (GND), 780nm laser diode for CD oscillates 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 (S252 ON in the KEYB
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.

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

Note:
Be sure to enter the ID number in Stop mode.
Use the service remote control (GGF1067) for operations. Only opening/closing of the tray are performed from the player.
It is necessary with a player with DVD-audio compatibility to set an individual number (ID number) and ID data. If the number and data are
not set correctly with the following procedure, operations in the future may not be guaranteed. You will find the ID number to be set on the

RF count value to use the disc distinction. It compares
threshold value of 14 and 15 and distinguishes the disc.
14. Disc distinction threshold value (DVD and CD)
Threshold value of the disc distinction. Distinguish it from
DVD if bigger than this value, and distinguish it from CD if
small.
1 Indication Method of The Mechanism Controller Debugging Screen
A debugging screen of the mechanism controller is indicated when pressing the test mode remote control unit [GGF1067] in
order of the and buttons.
