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)”.
SELF-DIAGNOSIS FUNCTION
Self-diagnosis display
This system has a Self-diagnosis display
function to let you know if there is a system
malfunction. The display shows a code made
up of 3 or 5 letters and a message alternately to
show you the problem. To solve the problem
refer to the following list. If any problem
persists, consult your nearest Sony dealer.
C11/Protected
The MD is protected against erasure.
cRemove the MD and slide the tab to close the
slot (see page 19).
C12/Cannot Copy
You tried to record a CD or MD with a format that
the system does not support, such as a CD-ROM.
cRemove the disc and turn off the system once,
then turn it on again.
C13/REC Error
Recording could not be performed properly.
cMove the system to a stable place, and start
recording over from the beginning.
The MD is dirty or scratched, or the MD does not
meet the standards.
cReplace the MD and start recording over from
the beginning.
C13/Read Error
The MD deck cannot read the disc information
properly.
cRemove the MD once, then load it again.
C14/Toc Error
The MD deck cannot read the disc information
properly.
c Replace the MD.
Erase all the recorded contents of the MD using
All Erase Function (see page 35).
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) or CD-RW (ReWritable
CD).
c The Serial Copy Management System prevents
making a digital copy (see page 57). You cannot
record a CD-R or CD-RW.
C71/Check OPT-IN
This appears momentarily because of the signal of
the digital broadcast during recording.
c There is no affect on the recorded contents.
No component is connected to the DIGITAL
OPTICAL IN jack, or a digital component is not

SERVICING NOTE
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 pickup block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
FOR MD
