When checking the emission of the laser diode during adjustments, never view directly downwards as this may lead to blindness.
Precautions for Using Optical Pick-up (KMS-280A)
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.

Flexible Circuit Board Repairing · Keep the temperature of the 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. 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.
SAFETY-RELATED COMPONENT WARNING!! COMPONENTS IDENTIFIED BY MARK ! OR DOTTED LINE WITH MARK ! ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION.

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 DOOR OPEN switch (S801) with tape.

SECTION 2 SELF-DIAGNOSTIC
2-1. GENERAL
This set uses the self-diagnostic system in which if an error occurs in playback/recording 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. 2) Remote controller LCD
