SECTION 1 SERVICING NOTE • When repairing this device with the power on, if you remove the MAIN board or open the upper panel assy, this device stops working. In this case, you can work without the device stopping by fastening the hook of the open/close detect switch (S801) with tape.

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 avove when checking it for adustment. It is feared that you will lose your sight. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (LCX-2R) 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.

Tape MAIN board S801

• This set is designed to perform automatic adjustment for each adjustment and write its value to EEPROM. Therefore, when EEPROM (IC802) has been replaced in service, be sure to perform automatic adjustment and write resultant values to the new EEPROM. (Refer to page 20.) laser-tap

• Replacement of CXD2660R (IC502) and CXR701081 (IC801) used in this set requires a special tool. Therefore, they cannot be replaced.

SECTION 4 TEST MODE 4-1. OUTLINE • This set provides the Overall adjustment mode (Assy mode) that allows CD and MO disc to be automatically adjusted when in the test mode. In this overall adjustment mode, the protect switch is detected to judge the disc, CD or 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. • The keys in the description refer to the keys on both set and remote commander unless otherwise specified. Though LCD display shows the LCD of the remote commander, same contents are also displayed on the LCD of the set.

4-2. TEST MODE 4-2-1. Setting Method of Test Mode There are two different methods to set the test mode: 1 Short BP801 (TEST) on the MAIN board with a solder bridge (connect pin y; of IC801 to the ground). Then, turn on the power. – MAIN

2 In the normal mode, turn on the HOLD switch on the set. While pressing the x key on the set, press the following remote control keys in the following order: > t > t . t . t > t . t > t . t X t X

4-2-2. Operation in Setting the Test Mode • When the test mode becomes active, first the display check mode is selected. (Press x key once, when the display check mode is not active.) • Other mode can be selected from the display check mode. • When the test mode is set, the LCD repeats the following display.

4-6. SELF-DIAGNOSIS DISPLAY MODE

• This set uses the self-diagnosis system in which if an error occurs in recording/playback mode, the error is detected by the model control and power control blocks of the microprocessor and information on the cause is stored as history in EEPROM. By viewing this history in test mode, it helps you to analyze a fault and determine its location. Total recording time has been recorded as optical pick-up using time, and it is compared with the total recording time in the self-diagnosis display mode to find when an error occurred. Clear both total recording time and the time in self-diagnosis display mode, when the optical pick-up was replaced. 1. Setting the test mode. (See page 13) 2. Press the MENU . key on the set or press the [DISPLAY] key on the remote commander activates the self-diagnosis display mode where the LCD display as shown below. LCD display

Press the X key or [REC] key on the set during display of self-diagnosis data when clearing the self-diagnosis data, or during display of total recording time when clearing the total recording time. Thus, “ClrOK?” will be displayed on the LCD, and press the same key again, and when self-diagnosis data is cleared “ErrCLR” is displayed and the data is cleared. Also when total recording time is cleared, “ RecT O” is displayed and it is cleared.

Press the [T MARK] or [DISPLAY] key on the remote commander for several seconds activates the key check mode where all segments of LCD turn OFF. (At the last two digits of DOT section, AD value of remote commander key line is displayed in hexadecimal) 3. When each key is pressed, it is displayed on the LCD, implying that it was successfully checked as shown below. However, for the slide switch on the set, it is not checked unless it is reciprocated. * The key pressed to enter the key check mode was already checked at that time. Set key Key

SECTION 5 ELECTRICAL ADJUSTMENTS

5-1. OUTLINE

5-4. NV RESET

• In this set, automatic adjustment of CD and MO can be performed by entering the test mode. (See page 13) However, before starting automatic adjustment, the memory clear, power adjustment and temperature adjustment must be performed in the manual mode. • The keys in the description refer to the keys on both set and remote commander unless otherwise specified. Though LCD display shows the LCD of the remote commander, same contents are also displayed on the LCD of the set.

• Setting method of NV reset 1. Select the manual mode of test mode, and set mode number 021NV Reset. LCD display

2. Press the X key. LCD display

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 • Laser power meter LPM-8001 (Part No. : J-2501-046-A) • Digital voltmeter 3.

13. To clear the data in overall adjustment mode, set the manual mode and change the mode number 021 (Res NV) to reset the NV. (See page 14) 14. When both CD and MO overall adjustments are OK, set the manual mode and clear the clock data. For the microprocessor version 1.20 or later, set the mode number 043 (Resume).

Check Method : 1. Select the manual mode of test mode, and set the laser power adjusting mode. (mode number 010) 2. Press the . key continuously until the optical pick-up moves to the most inward track. 3. Open the cover and set the laser power meter on the objective lens of the optical pick-up. 4. Press the N key, and set the laser MO read adjustment mode. (mode number 011) 5. Check that the laser power meter reading is 0.81 ± 0.08 mW. 6. Check that the voltage between TP1001 and TP1002 at this time is below 44 mV. 7. Press the N key, and set the laser CD read adjustment mode. (mode number 012) 8. Check that the laser power meter reading is 0.97 ± 0.10 mW. 9. Check that the voltage between TP1001 and TP1002 at this time is below 44 mV. 10. Press the N key, and set the laser MO write adjustment mode. (mode number 013) 11. Check that the laser power meter reading is 4.95 ± 0.50 mW. 12. Check that the voltage between TP1001 and TP1002 at this time is below 80 mV. 13. Press the x key. 14. Release the test mode.

Note: In the mode number 043 (Resume), “Res***” display cannot be seen because of too fast processing.
