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

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.

Laser component in this product is capable of emitting radiation exceeding the limit for Class 1.

Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be damaged by heat.

Flexible Circuit Board Repairing

• Keep the temperature of 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.

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.

This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior.

This caution label is located inside the unit.

CAUTION

Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

Iop DATA RECORDING AND DISPLAY WHEN OPTICAL PICK-UP AND NON-VOLATILE MEMORY (IC195 OF BD (MD) BOARD) ARE REPLACED

The Iop value labeled on the optical pick-up can be recorded in the non-volatile memory. By recording the value, it will eliminate the need to look at the value on the label of the optical pick-up. When replacing the optical pick-up or non-v olatile memory (IC195 of BD (MD) board), record the Iop value on the optical pick-up according to the following procedure.

Record Precedure:

1. In the power ON state, set the function to MD, and while pressing the DISPLAY and x buttons together, press V-GROOVE .

2. Move the Multi stick to display “[Service]”, and press the PUSH ENTER button.

3. Move the Multi stick to display “Iop Write” (C05), and press the PUSH ENTER button.

4. The display becomes “Ref=@@@.@” (@ is an arbitrary number) and the numbers which can be changed will blink.

5. Input the Iop value written on the optical pick-up. To select the number : Move the Multi stick. To select the digit :Press the MD REC MODE button while REC IT is lit.

6. When the PUSH ENTER button is pressed, the display becomes “Measu=@@@.@” (@ is an arbitrary number).

7. As the adjustment results are recorded for the 6 value. Leave it as it is and press the PUSH ENTER button.

8. “Complete!” will be displayed momentarily. The value will be recorded in the non-volatile memory and the display will become “Iop Write” (C05).

Display Precedure:

1. In the power ON state, set the function to MD, and while pressing the DISPLAY and x buttons together, press V-GROOVE .

2. Move the Multi stick to display “[Service]”, and press the PUSH ENTER button.

3. Move the Multi stick to display “Iop Read” (C26).

4. “@@.@/##.#” is displayed and the recorded contents are displayed. @@.@ : indicates the Iop value labeled on the optical pick-up. ##.# : indicates the Iop value after adjustment

5. To end , press the NAME EDIT/CHARACTER button while REC IT is lit, or press the MD REC MODE button to display “Iop Read” (C26).

CHECKS PRIOR TO PARTS REPLACEMENT AND ADJUSTMENTS

Before performing repairs, perform the following checks to determine the faulty locations up to a certain extent. Details of the procedures are described in “6 Electrical Adjustments”.

• 6-6-2. Laser power check (see page 41)

• 6-6-3. Iop Compare (see page 41)

• 6-6-4. Auto Check (see page 42)

Note:

The criteria for determination above is intended merely to determine if satisfactory or not, and does not serve as the specified value for adjustments. When performing adjustments, use the specified values for adjustments.

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 BT900 pin 3 and BT900 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 e xit the test mode, press the @/1 button, and turn OFF the po wer . When “TOC” disappears, disconnect the power plug from the outlet. If the test mode cannot be exited, refer to “Forced Reset” on page 12 .

from MC version, GC version, VC version, CD version, CDM version, ST version, TC version, TA version, TM version and BR version in this order, and returns to the model number and destination display.

5. When DISC 3 is pressed while the version numbers are being

displayed except model number and destination, year, month and day of the software creation appear. When DISC 3 is pressed again, the display returns to the software version display . When DISC 1 is pressed while year, month and day of the software creation are being displayed, the year, month and day of creation of the software versions are displayed in the same order of version display.

6. Press DISC 2 button, and the key check mode is activated.

7. In the key check mode, the fluorescent indicator tube displays

“K 0 VO 0 STICK N”. Each time a button is pressed, “K 0” value increases. Howev er, once a b utton is pressed, it is no longer taken into account. “VO 0” value increases like 1, 2, 3 ... if rotating VOLUME knob in “+” direction, or it decreases like 0, 9, 8 ... if rotating in “–” direction. Moving the stick changes the “STICK N” display. When moved up : “STICK When moved down : “STICK r” When moved to the left : “STICK T” When moved to the right : “STICK t”
