Self-diagnosis function
(When letters/numbers appear in the
display)
When the self-diagnosis function is activated to
prevent the system from malfunctioning, a five-
character service number (e.g., C 13 00) with a
combination of a letter and digits appears on
the screen. In this case, check the following
table.
C:13:00
First three
characters of
the service
number
Cause and/or
corrective
action
C 13
The disc is dirty.
, Clean the disc with a soft cloth
(see page 70).
C 31
The disc is not inserted correctly.
, Re-insert the disc correctly.
To prevent a malfunction, the
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

HCD-GX90D/RV800D
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.
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.
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.
