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.
Flexible Circuit Board Repairing
• Keep the temperature of 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.
Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.
This appliance is classified as
a CLASS 1 LASER product.
The CLASS 1 LASER
PRODUCT MARKING is
located on the rear exterior.
This caution
label is located
inside the unit.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 
0
 OR DOTTED LINE WITH
MARK

 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.
Self-diagnosis Function
(When letters/numbers appear in the
display)
The self-diagnosis function is activated to
prevent the system from malfunctioning. In
this case, a five-character service number
(e.g., C 13 00) with a combination of a letter
and digits appears on the screen and the
front panel display. Refer to the following
table.
First three

number
C 13
The disc is dirty.
, Clean the disc with a soft
cloth (page 8).
C 31
The disc is not inserted
correctly.
, Re-insert the disc
correctly.
E XX
To prevent a malfunction, the
(xx is a number) system has performed the self-
diagnosis function.
, Contact your nearest Sony
dealer or local authorized
Sony service facility and
give the 5-character
service number.
Example: E 61 10
C:13:00
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.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
Carry out the “S curve check” in “CD section adjustment” and check
that the S curve waveform is output several times.

ejection cam on the bottom surface. Therefore, the screw thread is
easily damaged. To prevent this damage, turn it carefully.
1
 Turn the cam in the direction of the arrow.
2
 Pull-out the disc tray.

• CLEANING THE OPTICAL PICK-UP
Note 1: 
In cleaning the lens, do not apply an excessive force
   As the optical pick-up is vulnerable, application of
   excessive force could damage the lens holder.
Note 2: 
In cleaning, do not use a cleaner other than exclusive
   cleaning liquid. (KK-91 or isopropyl alcohol)
Note 3: 
Wipe the obujective lens spirally from center toward
    outside. (See Figure A)
(Figure A)

• MOVEMENT CONFIRMATION BY THE REMOTE
  CONTROLLER OF OTHER MODELS
Signal code of the attached remote controller may vary in the
generation of CD/DVD player.
The signal code of FUNCTION, BAND, ST/MONO and
MEMORY is different with the remote controller for DAV-S400
and the remote controller for DAV-S550/S880/C770/C990.
Be careful when you confirm by the remote controller of the different
model.
