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)”.
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 three or five 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.
C12/Cannot Copy
You tried to record a CD or MD with a format that the system does not support, such as a CD­ROM.
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 insert it again.
C14/Toc Error
The MD deck cannot read the disc information properly.
cReplace the MD. cErase all the recorded contents of the MD
using the All Erase function.
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. You cannot record a CD-R.
C71/Check OPT-IN
This appears momentarily because of the signal of the digital broadcast during recording.
cThere is no affect on the recorded contents. No component is connected to the DIGITAL
OPTICAL IN jack, or a digital component is not connected properly.
cConnect a digital component to the DIGITAL
OPTICAL IN jack properly using a digital connecting cable (not supplied).
The connected digital component is not turned on.
cSee the operating instructions supplied with
the connected component and confirm whether the component is turned on.
The digital connecting cable connected to the DIGITAL OPTICAL IN jack is pulled out, or the connected digital component is turned off during digital recording.
cConnect the cable, or turn on the digital
component.
E0001/MEMORY NG
There is an error in the internal data that the system needs in order to operate.
cConsult your nearest Sony dealer.

Notes on chip component replacement
Never reuse a disconnected chip component.
Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
Keep the temperature of the 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.
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous ra­diation exposure.
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.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 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.

SERVICING NOTES

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 objecti ve lens.
LASER DIODE AND FOCUS SEARCH OPERATION CHECK
Carry out the S curve check in CD section adjustment and check that the S curve waveforms is output three times.
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.

CLEANING OBJECTIVE LENS OF OPTICAL PICK-UP
In cleaning the objective lens of optical pick-up, be sure the following below.
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.
2. In cleaning, do not use a cleaner other than exclusive cleaning
liquid (KK-91 or isopropyl alcohol).
3. Wipe the objective lens spirally from center toward outside.
(See Figure A)
(Figure A)
4. Eject the disk, if loaded.
5. Disconnect the power cord from the socket to shut off the power
supply.
6. When cleaning the objective lens of optical pick-up in CD,
refer to CD BASE UNIT (BU-21BD53) on page 26 for removing CD BASE UNIT (BU-21BD53).
