ELECTRICAL PARTS LIST ...................................... 53 –3– 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. –4– OPTICAL PICK-UP FLEXIBLE BOARD SECTION 2 GENERAL –5– This section is extracted from instruction manual. –6– –7– SECTION 3 DISASSEMBLY Note : This set can be disassemble according to the following sequence.

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.

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.
