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.
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
pick-up block. Therefore, when checking the laser diode emis-
sion, observe from more than 30 cm away from the objective lens.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur-
ing 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.
NOTES  ON  HANDLING  THE  OPTICAL  PICK-UP
BLOCK  OR  BASE  UNIT
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra-
diation exposure.
This appliance is
classified as a CLASS 1
LASER product. The
CLASS 1 LASER
PRODUCT MARKING
is located on the rear
exterior.
CAUTION
The use of optical instruments with this product will
increase eye hazard.
As the laser beam used in this CD/DVD Player is
harmful to eyes, do not attempt to disassemble the
cabinet. Refer servicing to qualified personnel only.
The following caution label is located inside the
apparatus.
NOTES ON MB BOARD EXCHANGE
If a MB board is exchanged, “DRIVE AUTO ADJUSTMENT’’
may be unable to be performed. In this case, initialize a memory
in the following procedure.
1.
Starting Test Mode (See page 11).
2.
Press the 2  button of remote commander to set the Drive
Manual Operation (See page 18).
3.
Press the 6 button of remote commander to set the Memory
Check (See page 20).
4.
Press the  [CLEAR]  button of remote commander to initialize a
memory.
