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 SelfDiagnosis Function (Error History Display Mode).
C11 / Protected The MD is protected against erasure. p Remove the MD and slide the tab to close the slot (page 37). C12 / Cannot Copy You are attempting to record a CD with a format that the system does not support, such as CD-ROM. p C13 / REC Error Recording is not possible. p Move the system to a stable place and start recording over from the beginning. The MD is dirty or is scratched or the MD does not meet the standards. p Change the MD with another one and start recording over from the beginning. C13 / Read Error The MD cannot read the disc information correctly. p Eject the MD once, then insert it again. C14 / Toc Error The MD cannot read the disc information correctly. p Change the MD with another one. p Erase all the recorded contents of the MD using the Erase function on page 52. C41 / Cannot Copy This unit complies with the Serial Copy Management System (SCMS) which limits the number of digital copies that can be made of any given digital audio source (page 90). C71 / Check OPT-IN You tried to record from the digital component when no component is connected to OPTICAL IN jack or the digital component is not connected correctly. p Connect the digital component correctly to OPTICAL IN jack with a digital optical cable. The power of the connected digital component is off. p Turn on the digital component. E0001 / MEMORY NG The component has internal problems. p Consult your nearest Sony dealer. E0101 / LASER NG There is a problem with the laser pickup. p The laser pickup may be damaged. Consult your nearest Sony dealer.

Self-diagnosis Display

This system has the Self-diagnosis display function to let you know if there is a system malfunction. The display shows a code made up of three 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.

FORCED RESET

The system microprocessor can be reset in the following procedure. Use these procedure when the unit cannot be operated normally due to the overrunning of the microprocessor, etc. Procedure : 1. Disconnect the AC outlet. 2. Momentary short between BT901 pin 3 and BT901 pin # by lead wire. 3. Momentary short between C416 pin 3 and C416 pin # by lead wire.

RETRY CAUSE DISPLAY MODE
In this test mode, the causes for retry of the unit during recording can be displayed on the fluorescent indicator tube. During playback, the track mode for obtaining track information will be set. This is useful for locating the faulty part of the unit. The following will be displayed : During recording and stop : Retry cause, number of retries, and number of retry errors. During playback : Information such as type of disc played, part played, copyright. These are displayed in hexadecimal. Procedure: 1. Press the x button and DISPLAY button, CINEMA SPACE button. 2. When the mode is set, RTs 00c 00e 000 is displayed. 3. Press the MD REC button to start recording. Then press the MD u button and start recording. 4. To check the track mode, press the MD u button to start play. 5. To exit the test mode, press the @/1 button, and turn OFF the power. When TOC disappears, disconnect the power plug from the outlet. If the test mode cannot be exited, refer to Forced Reset on page 12.

Reading the Display: Convert the hexadecimal display into binary display. If more than two causes, they will be added. Example When 42 is displayed: Higher bit : 4 = 0100 t b6 Lower bit : 2 = 0010 t b1 In this case, the retry cause is combined of CLV unlock and ader5. When A2 is displayed: Higher bit : A = 1010 t b7+b5 Lower bit : 2 = 0010 t b2 The retry cause in this case is combined of access fault, IVR rec error, and ader5.

Reading the Display: Convert the hexadecimal display into binary display. If more than two causes, they will be added. Example When 84 is displayed: Higher bit : 8 = 1000 t b7 Lower bit : 4 = 0100 t b2 In this case, as b2 and b7 are 1 and others are 0, it can be determined that the retry cause is combined of emphasis OFF, monaural, original, copyright exists, and write allowed. Example When 07 is displayed: Higher bit : 0 = 1000 t All 0 Lower bit : 7 = 0111 t b0+b1+b2 In this case, as b0, b1, and b2 are 1 and others are 0, it can be determined that the retry cause is combined of emphasis ON, stereo, original, copyright exists, and write prohibited.

As loading related operations will be performed regardless of the test mode operations being performed, be sure to check that the disc is stopped before setting and removing it. Even if the MD Z button is pressed while the disc is rotating during continuous playback, continuous recording, etc., the disc will not stop rotating. Therefore, it will be ejected while rotating. Be sure to press the CLEAR button while REC IT is lit, and press the MD Z button while REC IT is off after the disc stops rotating. 4-1-1.

If the nonvolatile memory data is abnormal, E001/MEMORY NG will be displayed so that the MD deck does not continue operations. In this case, set the test mode promptly and perform the following procedure. Procedure 1. Set the test mode. (Refer to 4-2.) 2. Normally a message for selecting the test mode will be displayed. However if the nonvolatile memory is abnormal, the following will be displayed. INIT EEP? 3. Press the x button and MD Z button together while REC IT is off. 4. Move the multi-stick and select MDM-7B. 5. Press the MD REC MODE button while REC IT is lit. If the nonvolatile memory is successfully overwritten, the normal test mode will be set and a message to select the test mode will be displayed.
SECTION 5 MECHANICAL ADJUSTMENTS
Precaution 1. Clean the following parts with a denatured alcohol-moistened swab: record/playback heads pinch rollers erase head rubber belts capstan idlers 2. Demagnetize the record/playback head with a head demagnetizer. 3. Do not use a magnetized screwdriver for the adjustments. 4.
