4、ecause 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 a

5、nd should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emis- sion, observe from more than 30 cm aw

6、ay from the objective lens. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be dam- aged by heat. Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C dur- ing repairing. Do not

7、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. This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior. Laser compon

When this mode is activated, a mechanism

22、is kept in stop status and GFS is not monitored. A checking status is displayed with disc LEDs. Setting the Test Mode 1.Load a disc on the tray of disc 1 and have a disc chucked. 2.Turn off the power switch once, and connect TP (TEST) and TP (GND) on MAIN board, then again turn on the power switch.

23、3.Thus, the test mode is activated. Note:When the test mode is activated, disc LEDs are all turned off and GFS is not monitored. Button Input and Operation in Test Mode Table 4-1. BUTTON 6 OPEN/ CLOSE 1 6 OPEN/ CLOSE 2 6 OPEN/ CLOSE 3 OPERATION LED on DISC 1 turns on, normal focus gain is set, and C

24、LV is fixed to 12 cm. LED on DISC 2 turns on, tracking servo and sled servo are turned off. LED on DISC 3 turns on, and tracking balance value is displayed. Releasing the Test Mode 1.Turn off the power switch, and disconnect a short wire be- tween TP (TEST) and TP (GND) on MAIN board. 2.Thus, the se

25、t becomes ready for normal operation. Notes: 1.Use YEDS-18 disc (Part No.: 3-702-101-01) unless otherwise indicated. 2.Use the oscilloscope with more than 10 M impedance. 3.Clean an object lens by an applicator with neutral detergent when the signal level is low than specified value with the fol- lo

26、wing checks. 4.Adjust the focus bias adjustment when optical pick-up is re- placed. Focus Bias Adjustment This adjustment is to be done when the optical pick-up is replaced. Condition: This adjustment is performed with the set placed hori- zontally. Connection: + BD board TP (RF) TP (VC) oscilloscop
