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 the 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. 

CAUTION 

Use of controls or adjustments or performance of procedures 

other than those specified herein may result in hazardous radiation 

exposure. 

This appliance is classified as a CLASS 1 

LASER product. 

The CLASS 1 LASER PRODUCT 

MARKING is located on the rear exterior. 

The following caution label is located 

inside the unit. 

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 PUB- 

LISHED BY SONY.

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 

pick-up block. Therefore, when checking the laser diode emission, 

observe from more than 30 cm away from the objective lens. 

CLEANING OF OPTICAL PICK-UP LENS 

In cleaning the lens of optical pick-up, use the air blower. 

Never use a cotton swab for cleaning the lens of optical pick-up, 

which otherwise causes a trouble.

This set performs automatic adjustment for each disc, and therefore 

the set need not be adjusted when parts are replaced, but it 

requires checking following the description in this section, 4-1. 

IC AND FLUORESCENT DISPLAY TUBE CHECK and 4-2. 

AUTO CHECK. 

For the check, the test mode is used. Wrong setting causes a trouble, 

thus requiring extreme care. 

BU Electrical Adjustment Mode 

The BU electrical adjustment mode is used to check the S curve 

waveform, traverse waveform and RF waveform. After a disc is 

placed on the tray, each time the [ l AMS L] 

dial is pressed, 

the check mode is switched in order for S curve waveformt 

traverse waveformtRF waveform. 


After setting the test mode, rotate the [ lAMS L] 

dial to select 

“9C BU DENCHO” and press the [ l AMS L] 


“BU MEASURE” will be displayed if the BU electrical adjustment 

mode becomes active.
