SECTION 1

SERVICING NOTE

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.

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.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (LCX-4R)

The laser diode in the optical pick-up block may suffer electrostatic break-down easily. When handling it, perform soldering bridge to the laser-tap on the flexible board. Also perform measures against electrostatic break-down sufficiently before the operation. The flexible board is easily damaged and should be handled with care.

• In performing the repair with the power supplied to the set, removing the MAIN board causes the set to be disabled. In such a case, fix a convex part of the open/close detect switch (S806 on MAIN board) with a tape in advance. Handle the FLEXIBLE board (overwrite head) with care, as it has been soldered directly to the MAIN board. In repairing the component side of MAIN board, connect the FLEXIBLE board (overwrite head) and the MAIN board with the lead wires in advance. (See page 8)

• Replacement of CDX2671-204GA (IC801) used in this set requires a special tool.

• On the set having the microcomputer version 1.000, some adjusted values were set in the manual mode at the shipment, but these data will be cleared when the NV is reset. Therefore, on the set having the microcomputer version 1.000, change the adjusted values following the Change of Adjusted Values immediately after the NV was reset. (See page 18)

• If the nonvolatile memory was replaced on the set, the modified program data must be written to the nonvolatile memory . In such a case, write the modified data that meets the microcomputer version following the patch data rewriting procedure at the replacement of nonvolatile memory. (See page 23)

TEST MODE

4-1. Outline

• This set provides the Overall adjustment mode that allows CD and MO discs to be automatically adjusted when in the test mode. In this overall adjustment mode, the disc is discriminate between CD and MO, and each adjustment is automatically executed in order. If a fault is found, the system displays its location. Also, the manual mode allows each individual adjustment to be automatically adjusted.

4-2. Setting Method of T est Mode

There are two different methods to set the test mode: 1 Short TAP801 (TEST) on the MAIN board with a solder bridge

(connect pin 3 of IC801 to the ground). Then, turn on the power.

MAIN BOARD (SIDE B)

4-3. Operation in Setting the Test Mode

• When the test mode becomes active, first the display check mode is selected.

• Other mode can be selected from the display check mode.

4-4. Releasing the Test Mode

For test mode set with the method 1: Turn off the power and open the solder bridge on T AP801 (TEST) on the MAIN board. Note: Remove the solders completely. Remaining could be shorted

with the chassis, etc. For test mode set with the method 2: Turn off the power. Note: If electrical adjustment (see page 18) has not been finished

completely, always start in the test mode. (The set cannot

start in normal mode)

4-8. Self-Diagnosis Result Display Mode

This set uses the self-diagnostic function system in which if an error occurred during the recording or playing, the mechanism control block and the power supply control block in the microcomputer detect it and record its cause as history in the nonvolatile memory. By checking this history in the test mode, you can analyze a fault and determine its location. Total recording time is recorded as a guideline of how long the optical pickup has been used, and by comparing it with the total recording time at the time when an error occurred in the selfdiagnosis result display mode, you can determine when the error occurred. Clear both self-diagnosis history data and total recording time, if the optical pickup was replaced.

ELECTRICAL ADJUSTMENTS

5-1. Outline

• In this set, automatic adjustment of CD and MO can be performed by entering the test mode (see page 12). However, before starting automatic adjustment, the memory clear, power supply adjustment, and laser power check must be performed in the manual mode.

• A key having no particular description in the text, indicates a set key.

• For the LCD display, the LCD display on the set is shown.

5-2. Precautions for Adjustment

1. Adjustment must be done in the test mode only.

After adjusting, release the test mode.

2. Use the following tools and measuring instruments.

• Test CD disc TDYS-1 (Part No. : 4-963-646-01)

• SONY MO disc available on the market

• Digital voltmeter

• Laser power meter LPM-8001

(Part No. : J-2501-046-A)

Therefore, on the set having the microcomputer version 1.000, modify the adjusted values through the following procedure immediately after the NV was reset.

1. Item numbers in which the adjusted values are to be modified Item number 832 Item number 862 Item number 871 Item number 872

2. Adjusted values modifying procedure

1) Select the manual mode of the test mode, and set item number 832 (see page 13).

5-10. Patch Data Rewriting When Nonvolatile

Memory was Replaced

When the microcomputer in this set is replaced with a different version of microcomputer, it is needed to initialize the modified program data in the nonvolatile memory and write specific modified data for the new version in the memory. If the microcomputer is replaced with a different version, the patch data should be rewritten as performed when the nonvolatile memory is replaced. For a version where the method to write patch data is not described, the modified data should be initialized as specified below:

• Initial set of modified data

Common note on Printed Wiring Board:

• Y : parts extracted from the conductor side.

• : Pattern from the side which enables seeing.

(The other layer’s patterns are not indicated.)

Caution: Pattern face side: Parts on the pattern face side seen from the (Side B) pattern face are indicated. Parts face side: Parts on the parts face side seen from the (Side A) parts face are indicated.

• Main board is four-layer printed board. However, the patterns of layers 2 and 3 have not been included in this diagrams.

Replacement of IC801 on main board

requires a special tool.

• Lead Layouts

Lead layout of conventional IC CSP (chip size package)

surface

Common note on Schematic Diagram:

• All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums.

• All resistors are in Ω and 1/ specified.

• % : indicates tolerance.

• C : panel designation.

Note:

The components identi-

fied by mark 0 or dotted line with mark 0 are critical for safety.

Replace only with part

number specified.

• A : B+ Line.

• Total current is measured with Minidisc installed.

• Power voltage is dc 3V and fed with regulated dc power supply from external power voltage jack.

• Voltage and waveforms are dc with respect to ground under no-signal conditions. no mark : PB ( ) : REC

• Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal production tolerances.

• Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances.

• Circled numbers refer to waveforms.

• Signal path.

E : PB k : REC (ANALOG) l : REC (DIGITAL)

: Impossible to measure

∗

W or less unless otherwise

Note:

Les composants identifiés par une marque 0 sont critiques pour la sécurité. Ne les remplacer que par une piéce portant le numéro spécifié.
