Precautions for Using Optical Pick-up (LCX-2E) As the laser diode inside the optical pick-up damages by static electricity easily, solder the laser tap of the Optical pick-up flexible board when handling. Also take the necessary measures to prevent damages by static electricity. Handle the Optical pickup flexible board with care as it breaks easily.

SECTION 1 SERVICING NOTE

1) 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 switch (MAIN board S809) with tape.

MAIN board S809

2) This set is designed to perform automatic adjustment for each adjustment and write its value to EEPROM. Therefore, when EEPROM (MAIN board IC802) has been replaced in service, be sure to perform automatic adjustment and write resultant values to the new EEPROM. Refer to section 4 Test Mode (page 10) for details.

SECTION 2 GENERAL

This section is extracted from instruction manual.

SECTION 4 TEST MODE

4-1. GENERAL
When entered in the TEST MODE, this set provides the Overall Adjustment mode which allows CD and MO discs to be automatically adjusted. In the Overall Adjustment mode , the system discriminates between CD and MO discs, performs adjustments in sequence automatically, and displays the faulty location if any fault is found. In the Manual mode, selected adjustments can be performed automatically. The attached remote control is used to operate the TEST MODE. Unless otherwise specified in the text, the key means that on the remote control. Remote control LCD

SECTION 8 ELECTRICAL PARTS LIST
NOTE: Due to standardization, replacements in the parts list may be different from the parts specified in the diagrams or the components used on the set. -XX and -X mean standardized parts, so they may have some difference from the original one. RESISTORS All resistors are in ohms. METAL:Metal-film resistor. METAL OXIDE: Metal oxide-film resistor. F:nonflammable Abbreviation FR : France model Ref. No. Part No. Description Items marked * are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these items. SEMICONDUCTORS In each case, u : , for example: uA. : A. uPA. : PA. uPB. : PB. uPC. : PC. uPD. : PD. CAPACITORS uF : F COILS uH : H The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified.
Les composants identifis par une marque 0 sont critiques pour la scurit. Ne les remplacer que par une pice portant le numro spcifi. When indicating parts by reference number, please include the board.
