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 SelfDiagnosis Function (Error History Display Mode).
The decks self-diagnosis function automatically checks the condition of the MD deck when an error occurs, then issues a three- or five-digit code and an error message on the display. If the code and message alternate, find them in the following table and perform the indicated countermeasure. Should the problem persist, consult your nearest Sony dealer.
Three- or fivedigit code/ Message C11/Protected Cause/Remedy The inserted MD is record-protected. , Take out the MD and close the recordprotect slot (page 14). You tried to record a CD with a format that the external device connected to the deck does not support, such as CD-ROM or video CD. , Remove the disc and insert a music CD. The recording was not made properly. , Set the deck in a stable surface, and repeat the recording procedure. The inserted MD is dirty (with smudges, fingerprints, etc.), scratched, or substandard in quality. , Replace the disc and repeat the recording procedure. The deck could not read the TOC on the MD properly. , Take out the MD and insert it again.
Three- or fivedigit code/ Message
Cause/Remedy The deck could not read the TOC on the MD properly. , Insert another disc. , If possible, erase all the tracks on the MD (page 32). The sound source is a copy of commercially available music software, or you tried to record a CD-R (Recordable CD). , The Serial Copy Management System prevents making a digital copy (page 52). You cannot record a CD-R. The sporadic appearance of this message is caused by the digital signal being recorded. This will not affect the recording.
E0001/ MEMORY NG
While recording from a digital component connected through the DIGITAL IN connector, the digital connecting cable was unplugged or the digital component turned off. , Connect the cable or turn the digital component back on. There is an error in the internal data that the deck needs in order to operate. , Consult your nearest Sony dealer. There is a problem with the optical pickup. , The optical pick-up may have failed. Consult your nearest Sony dealer.

4-9. AUTOMATIC SELF-DIAGNOSIS FUNCTION
This test mode performs CREC and CPLAY automatically for mainly checking the characteristics of the optical pick-up. To perform this test mode, the laser power must first be checked. Perform AUTO CHECK after the laser power check and Iop check. Procedure 1. Press the YES button. If LDPWR is displayed, it means that the laser power check has not been performed. In this case, perform the laser power check and Iop compare, and then repeat from step 1. 2. If a disc is in the mechanical deck, it will be ejected forcibly. DISC IN will be displayed in this case. Load a test disc (MDW-74/GA-1) which can be recorded. 3. If a disk is loaded at step 2, the check will start automatically. 4. When XX CHECK is displayed, the item corresponding to XX will be performed. When 06 CHECK completes, the disc loaded at step 2 will be ejected. DISC IN will be displayed. Load the check disc (MD) TDYS-1. 5. When the disc is loaded in step 4, the check will automatically be resumed from 07 CHECK. 6. After completing to test item 12, check OK or NG will be displayed. If all items are OK, CHECK ALL OK will be displayed. If any item is NG, it will be displayed as NG:xxxx. When CHECK ALL OK is displayed, it means that the optical pick-up is normal. Check the operations of the other spindle motor, thread motor, etc. When displayed as NG:xxxx, it means that the optical pick-up is faulty. In this case, replace the optical pick-up.
To check the emission of the laser diode during adjustments, never view directly from the top as this may lose your eye-sight.
5-3. PRECAUTIONS FOR USE OF OPTICAL PICKUP (KMS-260B)
As the laser diode in the optical pick-up is easily damaged by static electricity, solder the laser tap of the flexible board when using it. Before disconnecting the connector, desolder first. Before connecting the connector, be careful not to remove the solder. Also take adequate measures to prevent damage by static electricity. Handle the flexible board with care as it breaks easily.

5-4. PRECAUTIONS FOR ADJUSTMENTS
1) When replacing the following parts, perform the adjustments and checks with in the order shown in the following table. 2) Set the test mode when performing adjustments. After completing the adjustments, exit the test mode. Perform the adjustments and checks in group S of the test mode. 3) Perform the adjustments to be needed in the order shown. 4) Use the following tools and measuring devices. Check Disc (MD) TDYS-1 (Parts No. 4-963-646-01) Test Disk (MDW-74/GA-1) (Parts No. 4-229-747-01) Laser power meter LPM-8001 (Parts No. J-2501-046-A) or MD Laser power meter 8010S (Parts No. J-2501-145-A) Oscilloscope (Measure after performing CAL of prove.) Digital voltmeter Thermometer Jig for checking BD board waveform (Parts No. : J-2501-196-A) 5) When observing several signals on the oscilloscope, etc., make sure that VC and ground do not connect inside the oscilloscope. (VC and ground will become short-circuited.) 6) Using the above jig enables the waveform to be checked without the need to solder. (Refer to Servicing Note on page 6.) 7) As the disc used will affect the adjustment results, make sure that no dusts nor fingerprints are attached to it.

5-5. USING THE CONTINUOUSLY RECORDED DISC
* This disc is used in focus bias adjustment and error rate check. The following describes how to create a continuous recording disc. 1. Insert a disc (blank disc) commercially available. 2. Rotate the AMS knob and display CREC1 MODE. 3. Press the YES button again to display CREC1 MID. Display CREC (0300) and start to recording. 4. Complete recording within 5 minutes. 5. Press the MENU/NO button and stop recording. 6. Press the AEJECT button and remove the disc. The above has been how to create a continuous recorded data for the focus bias adjustment and error rate check. Note : Be careful not to apply vibration during continuous recording.
Checking Procedure: 1. Set the laser power meter on the objective lens of the optical pick-up. (When it cannot be set properly, press the m button or M button to move the optical pick-up.) Connect the digital volt meter to CN105 pin 1 (I+3V) and CN105 pin 2 (IOP). 2. Then, rotate the AMS knob and display LDPWR CHECK. 3. Press the YES button once and display LD 0.9 mW $. Check that the reading of the laser power meter become 0.84 to 0.92 mW. 4. Press the YES button once more and display LD 7.0 mW $. Check that the reading the laser power meter and digital volt meter satisfy the specified value. Specified Value : Laser power meter reading : 7.0 0.2 mW Digital voltmeter reading : Optical pick-up displayed value 10% (Optical pick-up label)
