XL-3000/3000C TROUBLESHOOTING When the CD does not function When the CD section does not operate when the objective lens of the optical pickup is dirty, this section may not operate. Clean the objective lens, and check the playback operation. When this section does not operate even after the above step is taken,check the following items. Remove the cabinet and follow the troubleshooting instructions.
PAGE 39
XL-3000/3000C Make sure that the disc is normal, and set the CD TEST MODE (STEP 1). Is the measured voltage as specified in circuit diagram? Check the main unit power supply circuit. No Yes Is "Er-CD01" displayed"? No Yes Move the pickup to most internal circumference side of disc. Turn the power off and reset the CD TEST MODE (STEP 1). Is "PU ERROR " not displayed? No Check the pattern between pin 58 (PU_IN) of IC701 and CNW803/CNS803. Check the between CNW803/CNS803 and PU-IN switch.
PAGE 40
XL-3000/3000C • Laser failure. Is +6.2V applied to the emiter of Q861 ? No Check the PWB pattern between emiter of Q607 and emiter of Q861. Yes Check the peripheral parts of IC804 and Q861. Is +5V applied to the collector of Q861 ? No Yes No Check the PWB pattern between collector of Q861 and pin 62 of IC802. No Check the PWB pattern between collector of Q861 and pin 1 of IC801.
PAGE 41
XL-3000/3000C • Focus servo sawtooth wave failure. Is sawtooh wave output to the pin 48 (FOO) of IC802 ? No IC802 is faulty. Yes 1.5~2.5sec Check the PWB pattern between emiter of Q607 and IC804. Is +6.2V applied to the pins 21 and 22 (VCC) of IC804 ? No Yes Is sawtooth wave obtained between pins 26 and 27 of IC804 ? No Yes Is +5V applied to the pin 7 (MUTE) of IC804 ? No Yes 1.5~2.5sec Check the PWB pattern between pin 7 of IC804 and pin 60 (CD STB) of IC701.
PAGE 42
XL-3000/3000C • HF error. Is output (tracking error signal) obtained at the pins 46 (TEI) and 47 (TEZI) of IC802 the CD TEST MODE "STEP 4" is changed to "STEP 5"? No Is output obtained at the pins 3 and No 8 of CNP802/CNW3. Optical pickup failure. Yes Yes test mode "step 4" Check the periphery of IC801. Check the PWB pattern between pin 12 (TEO) of IC801 and pins 46 and 47 of IC802. Is it normal ? test mode "step 5" TEI TEZI IC801 is faulty.
PAGE 43
XL-3000/3000C • Track search failure Does the sled motor run in FF/REW state when the SERVO TEST MODE "STEP1" is set? No Check as stated in item "SLED MOTOR OPERATION FAILURE". Yes Is the following wave output to the pin 49 (TRO) of IC802 during track search in normal playback? No IC802 failure. Yes TRO Is the following wave output to the pins 12 (TEO) of IC801 during track search in normal playback? No Yes TEO TEI Check the PWB pattern between pin 49 (TRO) of IC802 and pin 19 of IC804.
