  • Page 29 XL-560,570/C 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 "PU ERROR" displayed"? Move the pickup to most internal circumference side of disc.
  • Page 30 XL-560,570/C • Laser failure. Is +6.2V applied to the emiter of Q861 ? Check the PWB pattern between pin 16 of CNS602 and emiter of Q861. Check the peripheral parts of IC804 and Q861. Is +5V applied to the collector of Q861 ?
  • Page 31 XL-560,570/C • Focus servo sawtooth wave failure. IC802 is faulty. Is sawtooh wave output to the pin 48 (FOO) of IC802 ? 1.5~2.5sec Check the PWB pattern between pin 16 of CNS602 and IC804. Is +6.2V applied to the pins 1 and 30 (VCC) of IC804 ?
  • Page 32 XL-560,570/C • HF error. Is output (tracking error signal) obtained at the pins 46 (TEI) Optical pickup failure. Is output obtained at the pins 2 and and 47 (TEZI) of IC802 the CD TEST MODE "STEP 4" is 5 of BI802/CNS802 changed to "STEP 5"?
  • Page 33 XL-560,570/C • Track search failure Does the sled motor run in FF/REW state when the SERVO Check as stated in item "SLED MOTOR OPERATION FAILURE". TEST MODE "STEP1" is set? Is the following wave output to the pin 49 (TRO) of IC802 IC802 failure.
