NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.

Laser component in this product is capable of emitting radiation exceeding the limit for Class 1.

This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior.

CAUTION

Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be

damaged by heat.

Flexible Circuit Board Repairing

• Keep the temperature of soldering iron around 270˚C during repairing.

• Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering or unsoldering.

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

SECTION 4

TEST MODE

[MC Cold Reset]

• The cold reset clears all data including preset data stored in the

RAM to initial conditions. Execute this mode when returning the set to the customer.

Procedure:

1. Press three buttons x , DISPLAY , and DISC 5 simultaneously.

2. The fluorescent indicator tube displays “COLD RESET” and

the set is reset.

[CD Ship Mode]

• This mode moves the pickup to the position durable to vibra-

tion. Use this mode when returning the set to the customer after repair.

Procedure:

1. Press ?/1 button to turn the set ON.

2. Press V-GROOVE button and ?/1 button simultaneously.

3. After the "STANDBY" display blinks six times, a message

“LOCK” is displayed on the fluorescent indicator tube, and the CD ship mode is set.

[MC Hot Reset]

• This mode resets the set with the preset data kept stored in the

memory. The hot reset mode functions same as if the power cord is plugged in and out.

Procedure:

1. Press three buttons x , DISPLAY , and DISC 1 simultaneously.

2. The fluorescent indicator tube becomes blank instantaneously,

and the set is reset.

[CD Service Mode]

• This mode can run the CD sled motor freely. Use this mode, for

instance, when cleaning the pickup.

Procedure:

1. Press ?/1 button to turn the set ON.

2. Select the function “CD”.

3. Press three buttons x , DISPLAY , and Z 3 simultaneously.

4. The CD service mode is selected.

5. With the CD in stop status, turn the shuttle knob clockwise to

move the pickup to outside track, or turn the shuttle knob counter-clockwise to inside track.

6. To exit from this mode, perform as follows:

1) Move the pickup to the most inside track.

2) Press three buttons in the same manner as step 2.

Note: • Always move the pickup to most inside track when exiting from

this mode. Otherwise, a disc will not be unloaded.

• Do not run the sled motor excessively, otherwise the gear can be chipped.

[VACS ON/OFF Mode]

• This mode is used to switch ON and OFF the VACS (Variable Attenuation Control System).

Procedure:

Press the PUSH ENTER and x buttons simultaneously. The message “VACS OFF” or “VACS ON” appears.

[Change-over of MW Tuner Step between 9 kHz and 10 kHz]

• A step of MW channels can be changed over between 9 kHz and 10 kHz.

Procedure:

1. Press ?/1 button to turn the set ON.

2. Select the function “TUNER”, and press TUNER/BAND

button to select the BAND “MW”.

3. Press ?/1 button to turn the set OFF.

4. Press MODE SELECT and ?/1 buttons simultaneously, and

the display of fluorescent indicator tube changes to “MW 9 k STEP” or “MW 10 k STEP”, and thus the channel step is changed over.

[GC Test Mode]

• This mode is used to check the software version, FL tube, LED, keyboard and VACS.

Procedure:

1. Press three buttons x , DISPLAY , and DISC 2 simultaneously.

2. LEDs and fluorescent indicator tube are all turned on.

3. When you want to enter the software version display mode,

press DISC 1 . The model number and destination are displayed.

4. Each time DISC 1 is pressed, the display changes starting

from MC version, GC version, VC version, CD version, CDM version, ST version, TC version, TA version, TM version and BR version in this order, and returns to the model number and destination display.

5. When DISC 3 is pressed while the version numbers are being

displayed except model number and destination, year, month and day of the software creation appear. When DISC 3 is pressed again, the display returns to the software version display. When DISC 1 is pressed while year, month and day of the software creation are being displayed, the year, month and day of creation of the software versions are displayed in the same order of version display.

6. Press DISC 2 button, and the key check mode is activated.

7. In the key check mode, the fluorescent indicator tube displays

“K 0 VO 0 STICK N”. Each time a button is pressed, “K 0” value increases. However, once a button is pressed, it is no longer taken into account. “VO 0” value increases like 1, 2, 3 ... if rotating VOLUME knob in “+” direction, or it decreases like 0, 9, 8 ... if rotating in “–” direction. Moving the stick changes the “STICK N” display. When moved up : “STICK When moved down : “STICK r” When moved to the left : “STICK T” When moved to the right : “STICK t”

8. Also when DISC 3 is pressed after lighting of all LEDs and FL

tubes, value of VACS appears.

9. To exit from this mode, press three buttons in the same manner

as step 1, or disconnect the power cord.

R”

[MC Test Mode]

• This mode is used to check operations of the respective sections of Amplifier, Tuner, CD and Tape.

Procedure:

1. Press the ?/1 button to turn on the set.

VIDEO CD COLOR-BARS MODE

On this mode, the data of the color-bars signal as a picture signal and the 1kHz sine wave signal as a sound signal are output by the mechanism control microcomputer (IC502) for video CD signal check. When measurement of the voltage and waveform on the VIDEO board, perform it in this mode. For reference, the color-bars signal can be observed at J302 (VIDEO OUT) and the sound signal can be observed at J101 (VIDEO/MD (AUDIO) OUT) using an oscilloscope.

1. Connect the lead wire to both ends of the land of SL503 of the VIDEO board.

2. Press the ?/1 button to turn ON the power. Press FUNCTION button to select CD.

3. After 2 or 3 seconds later, connect the lead wire.
