XV-SA70BK/XV-SA75GD
(3) Traverse movement NG 1.Defective traverse driver *Has the voltage come between terminal of CN101 "1" and "2" ? 2.Defective BTL driver (IC271) *Has the motor drive voltage gone out to IC271"17" or "18"? 3.Has the control signal come from servo IC or the microcomputer? *Is it "H" while the terminal of IC271"9"(STBY1) ? *TRSDRV Is the signal input? (IC201 "51") 4.TRVSW is the signal input from microcomputer? (IC401 "50") (4) Focus ON NG * Is FE output ? --- Pattern, IC101 * Is FODRV signal sent ? (R279) --- Pattern, IC201 "5" * Is driving voltage sent ? IC271 "13", "14" --- If NG, pattern, driver, mechanical unit . * Mechanical unit is defective. (5) Tracking ON NG * When the tracking loop cannot be drawn in, TE shape of waves does not settle. * Mechanical unit is defective. Because the self adjustment cannot be normally adjusted, the thing which cannot be normally drawn in is thought. * Periphery of driver (IC271) Constant or IC it self is defective. * Servo IC (IC201) When improperly adjusted due to defective IC. (6) Spindle CLV NG * IC101 -- "35"(RF OUT), "30"(ARF-), "31(ARF+). * Does not the input or the output of driver's spindle signal do the grip? * Has the tracking been turned on? * Spindle motor and driver is defective. * Additionally, "IC101 and IC201" and "Mechanism is defective(jitter)", etc. are thought.
(7) Address read NG * Besides, the undermentioned cause is thought though specific of the cause is difficult because various factors are thought. Mechanism is defective. (jitter) IC201, IC301, IC401. The disc is dirty or the wound has adhered. (8) Between layers jump NG (double-layer disc only) Mechanism defective Defect of driver's IC(IC271) Defect of servo control IC(IC201)
