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.
This appliance is classified as a CLASS 1 LASER product. The
CLASS 1 LASER PRODUCT MARKING is located on the rear
exterior.
Laser component in this product is capable
of emitting radiation exceeding the limit for
Class 1.
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.
FOR DVD
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.
FOR MD
NOTES  ON  LASER  DIODE  EMISSION  CHECK
Never look into the laser diode emission from right above when
checking it for adjustment. It is feared that you will lose your sight.
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.
This caution
label is
located inside
the unit.
Ver 1.2
NOTE OF REPLACING THE DVD BOARD
When replacing the DVD board, since the adjustment value is not
set up correctly, “Drive Auto Adjustment” can’t be performed.
In this case, initialize Memory in the following procedures.
Procedure:
1. Set the DVD Service Mode. (See page 44)
2. Press the [2] key of the remote commander, and set the “DRIVE
MANUAL OPERATION”. (See page 49)
3. Press the [6]  key of the remote commander, and set the “6.
Memory Check”. (See page 51)
4. Press the [CLEAR] key of the remote commander, and initialize
Memory.
