Troubleshooting.pdf | TroubleShooting Check the power source and initial state. Is electrity of 5V and 12V normally input after the connecting the power cable ? Y Do Y302 oscillate ? Y Dose the voltage of the 158pin of IC304 (initial power on) change from 5V to 0V ? Y Dose the voltage of the 58pin of IC304 change from 0V-5V-0V ? Y Is electricity of 3.3V normally output from the 3pin of IC103 ? Y When you transfer the P/U to the outer cycle, and turn the power on, dose it move to the inner one? Y TRAY IN/OUT ? Y LASER DIODE ON ? Y FOCUS UP/DOWN ? Y FOCUS LOCK ? Y DISC rotation? Y SPINDLE LOCK ? Y AUDIO OUTPUT ? N Refer to `NO AUDIO OUTPUT' N Refer to `NO SPINDLE MOTOR ROTATION' N N N Refer to `NO FOCUSE LOCK' N Refer to `NO LASER DIODE ON' N Refer to `Check TRAY OPEN / CLOSE' N N If the power of IC103(1pin) 5V is normal when you check, replace IC103. N Check out IC304(58pin) change from 0V-5V-0V. C201(11pin). N If the power of IC304(158pin) is normal when you check circuit. N If the power of Y302 is normal w |
