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 DISCSPlease use the following test discs for the check on the CD section.
YDES-18 (Part No. 3-702-101-01) PATD-012 (Part No. 4-225-203-01)
SAFETY-RELATED COMPONET 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.
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostat-ic 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 fl exible board is easily damaged and should be handled with care.
NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focused on the disc refl ective 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.
CAUTIONUse of controls or adjustments or performance of procedures other than those specifi ed 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-fi xed resistor located at the side of optical pick-up block.

UNLEADED SOLDERBoards 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 MARKUnleaded 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 fl ow)
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.
This label is located on the bottom of the chassis.

SECTION 1SERVICE NOTE
EXTENSION CABLE AND SERVICE POSITIONWhen 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).
NOTE FOR REPLACEMENT OF THE SERVO BOARDWhen 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.

When indicating parts by reference num-ber, please include the board name.
Note:• Due to standardization, replacements in
the parts list may be different from the parts specifi ed in the diagrams or the com-ponents used on the set.
• -XX and -X mean standardized parts, so they may have some difference from the original one.
• Items marked “*” are not stocked since they are seldom required for routine ser-vice.
Some delay should be anticipated when ordering these items.
• CAPACITORS uF: �F
• COILS uH: �H• RESISTORS All resistors are in ohms. METAL: Metal-fi lm resistor. METAL OXIDE: Metal oxide-fi lm resistor. F: nonfl ammable• SEMICONDUCTORS In each case, u: �, for example: uA. . : �A. . , uPA. . , �PA. . , uPB. . : �PB. . , uPC. . , �PC. . , uPD. . : �PD. .
The components identifi ed by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specifi ed.
