SAFETY-RELATED COMPONENT WARNING!
COMPONENTS IDENTIFIED BY MARK 0OR DOTTED LINE
WITH MARK 0ON 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.
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.
TEST DISCS
Please use the following test discs for the check on the CD
section.
YEDS-18 (Part No. 3-702-101-01)
PATD-012 (Part No. 4-225-203-01)
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electro-
static 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.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radia-
tion exposure.
If the optical pick-up block is defective, please replace the whole
optical pick-up block.
Never turn the semi-fixed resistor located at the side of optical
pick-up block.

TABLE OF CONTENTS
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 °C higher
than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

SECTION 1
SERVICE NOTE
EXTENSION CABLE AND SERVICE POSITION
When repairing or servicing this set, connect the jig (extension
cable) as shown below.
• Connect the MAIN board (CN701) and the SERVO board
(CN401) with the extension cable (Part No. J-2502-076-1).
SERVO BOARD

MAIN BOARD
CN701 J-2502-076-1
NOTE FOR REPLACEMENT OF THE SERVO BOARD
When repairing, the complete SERVO board (Part No.
A-1555-002-A) should be replaced since any parts in the SERVO
board cannot be repaired.
NOTE FOR REPLACEMENT OF THE USB CONNECTOR
(CN902)
To replace the USB connector requires alignment.
1. Insert the USB connector into the front panel.
2. Place the KEY board on the front panel and align the terminals
of the USB connector with the holes in the KEY board.
3. Solder the four terminals of the connector.
NOTE FOR THE 20-PIN CONNECTOR (CN901)
Do not use alcohol to clean the 20-pin connector (CN901) connect-
ing the front panel with the main body.
Do not touch the connector directly with your bare hand. Poor con-
tact may be caused.
