SAFETY INFORMATION

A

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 trainedto 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.

B

C

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 : 650 nm

FOR CD : MAXIMUM OUTPUT POWER : 5 mW

WAVELENGTH : 780 nm

LABEL CHECK

Location: Printed on the Rear Panel

WARNING !

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 loadingstatus detection switch for the clamp position (the center terminal of S101 is shorted to +3V). When the voltage of IC101-pin 20 is +3V, IC601 (microprocessor)

-pin 83 is +3V and IC601-pin 84 is +3V, 650nm laser diode for DVD oscillates in the DVDM Assy.

When the voltage of IC101-pin 20 is +3V, IC601 (microprocessor)

-pin 83 is 0V (GND) and IC601-pin 84 is +3V, 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 (S104 ON in the FLKY 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.

∗ : See page 70.

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%).

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

Cautions:

Because there is not a Spacer for height adjustment in adjustment after the second time, will keep it at need. (This parts is Traverse mechanism exclusive use of a model for 2001 years)

Put a spacer between a Tangential (or Radial) adjustment screw and Mechanism Base and turn each screw to adjust the height. (Refer to "6.1 ADJUSTMENT ITEMS AND LOCATION".)

7.1 DIAGNOSIS

7.1.1 ID NUMBER AND ID DATA SETTTING

A

Entering the ID Number and ID Data for Players with DVD-Audio and DVD-RW Compatibility

It is necessary with a player with DVD-audio and DVD-RW 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 yellow label on the rear panel.

Important: If no yellow label is found on the rear panel, write down the specified ID number by checking it according to "How to confirm the ID number" shown below.

The Input is Necessary When:

B

• Downloading FLASH-ROM is finished. (The latest version must be downloaded when a repair is made.)

• "No ID Number" is displayed on the screen or FL display immediately after the power is turned on or in Stop mode.

• If "No ID DATA" is displayed, the ID data must be entered.

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. Use Disc No. : GGV1084

How to Input the ID Number and ID Data

1

C

To enter the input mode, press ESC + STEREO in a status with no ID number set, such as after FLASH-ROM downloading.

2

As number input is enabled when the unit enters the input mode, input the 9-digit ID number. (The entered number is also displayed on the FL display.)

7.1.2 SELF-DIAGNOSIS FUNCTION OF PICKUP DEFECTIVE

This unit can confirm the laser diode current value (DVD: 650nm, CD: 780nm) of pickup on the Test Mode screen. (Press the ESC → TEST keys in order on the test mode remote control unit (GGF1067) to enter the test mode.)

A

It's effective in case of the following condition.

Symptom

• Indicates "No Disc" in FL display.

• Player does not playback, etc..

Procedure of Self-Diagnosis

1 Enter the Test mode. 2 When diagnosing the 650nm laser diode:

B

Press the → keys in order, and turn on the laser diode (It light-up for nine seconds.). When diagnosing the 780nm laser diode: Press the → keys in order, and turn on the laser diode (It light-up for nine seconds.).

When let it turn on once again after performed 2 once, After pressed REP.B key once 650nm: Press the → keys in order 780nm: Press the → keys in order

3 Confirm the indicated value of the laser diode current (LDI). (Refer to following figure.)

TEST 1

TEST 4
