Page 36: Troubleshooting
XL-1500W 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.
Page 37 XL-1500W 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. Is "Er-CD01" displayed"? Move the pickup to most internal circumference side of disc.
Page 38 XL-1500W • Laser failure. Is +7.2V applied to the pin 1 of CNW805 ? Check the PWB pattern between emitter of Q605 and CNP805/ CNW805. Check the peripheral parts of ZD801,C820 and C821. Is +5V applied to the cathode side of ZD801 ?
Page 39 XL-1500W • Focus servo sawtooth wave failure. IC801 is faulty. Is sawtooh wave output to the pin 33 (FOO) of IC801 ? 1.5~2.5sec Check the PWB pattern between pin emitter of Q605 and IC803. Is +7.0V applied to the pins 21 and 22 (VCC) of IC803 ?
Page 40 XL-1500W • HF error. Is output (tracking error signal) obtained at the pins 31 (TEI) Optical pickup failure. Is output obtained at the pins 3 and and 32 (TEZI) of IC801 the CD TEST MODE "STEP 4" is 8 of CNP801/CNW801.
Page 41 XL-1500W • Track search failure Check as stated in item "SLED MOTOR OPERATION FAILURE". Does the sled motor run in FF/REW state when the SERVO TEST MODE "STEP1" is set? Is the following wave output to the pin 34 (TRO) of IC801 IC801 failure.
