CD-C422/C422C/C2800/C2800C TROUBLESHOOTING (CD SECTION) 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-C422/C422C/C2800/C2800C • When the CD tray fails to open or close. Is there following voltage input in specific state of IC701 pin 19? Open state: 0V Close state: 0V Intermediate state between open state and close state: 4.3V Check the OPEN CLOSE SW and the wiring from the IC701 pin 19 to the OPEN CLOSE SW. No Yes Is H output to IC2 pin 24 or 25 for 7 seconds when the OPEN/ CLOSE key is pressed?IC91 is defective. Replace it. Check the wiring of the IC2 pins 24 and 25, IC91 pins 1 and 3.

CD-C422/C422C/C2800/C2800C • Playback can only be performed when a disc is loaded. Is the Focus servo active? (Can you hear it working?) No Check the laser diode driver. Check the area around IC1(16) - (21) (focus servo circuit). No If the disc is not turning, the DRF should not change to "H". Yes Yes Does the DRF signal change from "L" to "H"? Check the spin system. Yes Yes No Is HF waveform normal (see the Fig.34-1, 2)? Check the periphery of IC1 pins 41 and 42. Level is abnormal.

CD-C422/C422C/C2800/C2800C • Checking the spin system. Play operation is performed without disc. Yes Yes The turntable rotates a little. The spin driver circuit is normal. No Yes The turntable fails to rotate or rotates at high speed. Check the periphery of IC1 pins 23 to 27, pin 39, and pin 40, IC2 pin 12 and pin 13, IC5 to CNP3. • Checking the VCO-PLL system Play operation is performed when disc exits. Yes Although HF waveform is normal, TOC data cannot be read. Yes Check PDO waveform (Fig. 35).
