11、erated 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
12、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 emission, observe from more than 30 cm away from the objective lens. LASER DIODE
13、AND FOCUS SEARCH OPERATION CHECK Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveform is output three times. WRITING OF FOCUS/TRACKING AUTO GAIN DATA General CD palyers using digital servo ICs automatically adjust the focus/tracking gain each time the disc is
14、changed. In this unit, the gain of the standard disc (YEDS-18) is written in the non-volatile memory (IC203:X24C01S) of the servo board so that the gain need not be re-adjusted when changing discs. Therefore, if the servo board, IC203 of the servo board, or optical pick-up has been replaced, be sure
15、 to write the auto gain data. 1. Connect TP (ADJ: Pin 3 of CN515) to GND (Ground), and turn ON the POWER switch. 2. Insert the test disc (YEDS-18). (The TOC data of the disc will be read.) This memorizes the auto gain data of the test disc. Note: If the disc is replaced without turning OFF the power
16、, the auto gain data of the last disc inserted will be memorized. If the POWER switch is turned ON without connecting TP (ADJ) to GND, the auto gain data will not be memorized when the disc is inserted, and the data memorized the last time will be taken as the focus/tracking data. FLUORESCENT INDICA
17、TOR TUBE FULL LIGHTING MODE 1. Connect TP (AFJ:Pin 2 of CN515) to GND (Ground), and turn ON the POWER switch. 2. The bridge check (check for short-circut between pins of the S RAM (IC202 of the servo board) is performed, and all the FL tubes light up if there is no bridge. 3. When a key other than t
18、he p(stop) key is pressed, the correspond- ing FL tubes lights up. Each time the p(stop) key is pressed, all the FL tubes light up.
