CD-C831W ADJUSTMENT • FM Notes: 1: Description of the "FM IF Adjustment" is not carried on this Manual. It is because the IF coil in the FM front end section has been best adjusted in the factory so that its further adjustment is not needed at the field. When replacing the FM front end assembly, no adjustment is needed either.
CD-C831W TEST MODE • Setting the test mode Any one of test mode can be set by pressing several keys as follows. + + TEST: CD operation test • TEST mode Function — CD test mode Setting of TEST mode Indication of CD TST mode (Fig. 11-1) IL is not performed. OPEN/CLOSE operation is manual operation. The pickup can be moved by using the ( LASER ON Tracking on the spot. SERVO OFF PLAY key input ) or ( ) key. Tracking on the spot.
CD-C831W 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-C831W 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-C831W • When the turntable fails to stop. 5V Is from 2.5V 5 V till 2.5V down pulse (approx. 300 ms) 0V No input into the IC701 pin 21 when the turntable is rotating? Check the SWM3 and the wiring from the IC701 pin 21 to the SWM3. Yes Is there following voltage input on the IC701 pin 21 in the specific state? When the CD mechanism is moved up: 0V In other states: 4.3V No Check the MECHA UP SW and the wiring from the IC701 pin 21 to the MECHA UP SW. Yes Check IC2 pin26 the periphery.
CD-C831W • 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. No OK IC2 defective.
CD-C831W • 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.37-1, 2)? Check the periphery of IC1 pins 41 and 42. Level is abnormal. Yes Yes Check the spin system.
CD-C831W • 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, IC3 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. 38).
