CD-CH1000 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.
CD-CH1000 Check in the CD test mode. STEP 1 Does the display "E-CD01" appear? Yes No Does the pickup move to the inner/outer position using the 'UP'/'DOWN' key? Check the line of PU-IN SW. Check from pin 2 of CNP6 via pin 25 of CNP1 to pin 94 of IC901. No Check the line of the slide control. Check from pins 3 and 4 of CNP6 via pins 17, 18 and 22 of IC5 to pin 40 of IC2. No Check from pins 7 and 8 of CNP5 via Q4 and pins 6 and 7 of IC6 to pin 38 of IC2.
