    11. Checking the reset port Pin 81 of IC202, pin 124, 186 of IC501 and pin 12 of IC503 are related to RESET. We can know whether IC is intialized or not through those ports. The waveform shows the status when the reset signal works normally. If the /M-RESET is abnormal, then check the front u-com(IC901) and replace it /M-RESET (Pin124 of IC501) DSP_RST (Pin 81 of IC202)

    13. Checking the track jump TE and TACT signals are output respectively from pin 54 and pin 34 of IC 202 during a normal play. SLED signal is output pin 29 of IC 202 and flow into pin 15 and pin 18 of IC 201 to operate a sled motor when to skip chapters or to scan.

  • Page 18: The Status Focus And Spindle Motor

    15. The status Focus and spindle motor The waveform is to display F+ signal from pin 9 IC201 and SPM+ from pin 10 IC201. F+ is used to control a focus actuator of pick - up and SPM+ is used to operate a spindle motor. So, we can know the position of the acuator and the speed and rotating direction of the spindle motor through those signals.
