6、is intended for qualified service technicians ; it is not meant for the casual do- it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual.Improperly performed repairs

7、can adversely affect the safety and reliability of the product and may void the warranty. If you are not qualified to perform the repair of this product properly and safely, you should not risk trying to do so and refer the repair to a qualified service technician. WARNING ! THE AEL (ACCESSIBLE EMIS

8、SION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR CLASS 1. A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS. LASER DIODE CHARACTERISTICS FOR DVD : MAXIMUM OUTPUT POWER : 5 mW WAVELEN

9、GTH : 650 nm FOR CD :MAXIMUM OUTPUT POWER : 5 mW WAVELENGTH : 780 nm Additional Laser Caution : See page 80. 1. Laser Interlock Mechanism Loading switch (S101 on the LOAB Assy) is used for interlock mechanism of the laser. When this switch turned ON in SW2 (XCLOSE) side (OPEN signal is 0V and XCLOSE

10、 signal is 3.5V), a laser becomes the status which can completely oscillation. Furthermore, the laser completely oscillates in the disc judgment and disc playback. When player is power ON state and laser diode is not completely oscillating, 780nm laser diode is always oscillating by half power. Lase

11、r diode is driving with Q101 (650nm LD) and Q102 (780nm LD) on the DVDM Assy. Therefore, when short-circuit between the emitter and collector of these transistors or the base voltage is supplied for transistors turn on, the laser oscillates. (failure mode) In the test mode , there is the mode that t

12、he laser oscillates except for the disc judgment and playback. LD ON mode in the test mode oscillates with the laser forcibly. The interlock mechanism mentioned above becomes invalid in this mode. 2. When the cover is open, close viewing through the objective lens with the naked eye will cause expos

13、ure to the laser beam.
