Sony RCD W500C  US Model Canadian Model COMPACT DISC RECORDER - Self diagnosis - Program setting - Circuit diagram

Self-diagnosis Function
When the self-diagnosis function is activated to prevent the player from malfunctioning, three character service numbers in a combination with a message appears in the display.
C12/ Cannot Copy:  You are trying to record a disc that cannot be played back in DECK-A or with an external device, such as CD-ROM or VIDEO CD.
• Remove the disc, and then insert a music CD for playback.
C13/ Rec Error:  Recording has not been completed successfully because of vibration.
• Relocate the unit in a place free of vibration and restart the recording again.
The disc you try to record is excessively dirty (such as oil stained or finger marked) or scratched. Or the disc is not normal.
• Replace the disc with another one and restart the recording again.
C14/TOC Error:  The unit did not read the TOC information.
• Insert other discs.
C41/Cannot Copy:  The sound source you are trying to record is a copy of commercial music software. Or you are trying to record on a CD-R/CD-RW digitally.
• Because of the restriction of the Serial Copy Management System, you cannot record a copy of commercial music software.  Neither can you record a CD-R/CD-RW digitally.
C71/ Din Unlock:  If this message is displayed momentarily, this is not an error. It is caused by the digital signal during recording.
During recording of a digital sound source, the connecting cable has been disconnected or the player of the sound source has turned off.
• Connect the cable or turn on the digital player.

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.  The emission check enables continuous checking of the S curve.
