CD-C606/1900,CP-C606/1900 NOTES ON SCHEMATIC DIAGRAM • Resistor: To differentiate the units of resistors, such symbol as K and M are used: the symbol K means 1000 ohm and the symbol M means 1000 kohm and the resistor without any symbol is ohm-type resistor. Besides, the one with “Fusible” is a fuse type. • Capacitor: To indicate the unit of capacitor, a symbol P is used: this symbol P means micro-micro-farad and the unit of the capacitor without such a symbol is microfarad.

CD-C606/1900,CP-C606/1900 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 36
CD-C606/1900,CP-C606/1900 • When turntable fails to move. Is there following voltage input on the IC701 pin 41 in the specific state? When the CD mechanism is moved up: 0V In other states: 4.3V No Check the MECHA UP switch and the wiring from the IC701 pin 41 to the MECHA UP switch. Yes Is L output from the IC2 pin 27 during SEC when the disc skip switch is pressed? Check the wiring of IC2 pin 27 and Q51 pin 2. No OK Yes IC2 defective.

CD-C606/1900,CP-C606/1900 • The CD operating keys work. Check the Focus - HF system. Playback can be performed without a disc. Yes Does the pick-up move up and down twice? Focus search OK Yes No Does the output waveform of IC1(16)(FD) match that shown in Fig. 35-1? Check the area around IC3-CNP2. Yes No Check the IC1(50)(CLK) line, 4MHz. Check the microcomputer data on pins (51)(CL), (52)(DAT) and (53)CE. Focus search is performed two times when play operation is done without disc. 0.5s 0.
PAGE 38
CD-C606/1900,CP-C606/1900 • Check the tracking system. Check waveform of IC1 pin 7 (TE). The waveform shown in Fig. 36-1 appears, and no-disc state appears soon. Play is possible in TEST mode. Data cannot be read. Yes Yes Yes Tracking servo is inoperative. Yes Although IL is possible, Yes play is impossible. Check the VCO-PLL system. Check the periphery of IC 1 pin 8 to pin 15, and IC 5 to CNP2. Normal jump is impeded, and the program top cannot be reached.
