SELF-DIAGNOSIS FUNCTION
The self-diagnosis function consists of error codes for customers which are displayed automatically when errors occur, and error codes which
show the error history in the test mode during servicing. For details on how to view error codes for the customer, refer to the following box
in the instruction manual. For details on how to check error codes during servicing, refer to the following “Procedure for using the Self-
Diagnosis Function (Error History Display Mode)”.
Procedure for using the Self-Diagnosis Function (Error History Display Mode).
Note: Perform the self-diagnosis function in the “error history display mode”in the test mode. The following describes the least required
procedure. Be careful not to enter other modes by mistake. If other modes are entered accidentally, press the MENU/NO button to
exit the mode.
1. Connect the mains lead to the mains while pressing the DIMMER , FUNCTION , and xbuttons together, then release the DIMMER,
FUNCTION , and xbuttons simultaneously. While the test mode is set. “[Check]”will be displayed.
2. Move ./> left and right to display “[Service]”and press the ENTER/YES button.
3. Move ./> left and right to display “Err Display”.
4. Press the ENTER/YES button to enter the error history mode. “op rec tm”will be displayed.
5. Select the item to be displayed or executed using ./> .
6. Press the REC MODE button to display the selected item.
7. Press the REC MODE button another time to return to step 4.
8. Pressing the MENU/NO button displays “Err Display”and exits the error history display mode.
9. To exit the test mode, press the REPEAT button. This sets the standby state and ends the test mode.
C41/Cannot Copy
The sound source is a copy of a commercially
available music software, or you tried to record a
CD-R (Recordable CD).
cThe Serial Copy Management System prevents
making a digital copy (Refer to Operating
Instruction on page 48). You cannot record a

SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0OR DOTTED LINEWITH
MARK 0ON 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.
CAUTION
Use of controls or adjustments or performance of procedures
otherthanthosespecified 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.
FOR CD
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.
