INSPECTION -visually check all parts for: solder bridges or splashes, backwards or missing component orientation. B. POWER SUPPLY VOLTAGES 1. CR105-21V 2. CR102+21 3. CR302-5V 4. CR301+5V 5. CR104-12V 6. CR103+12V 7. R305-12V 8. R301+12V 9. C202+5V C. DAC OFFSETS CALIBRATION -maximum 6mV 1. Measure DC voltage of J404A to J404B LGND. Divide 5127 by this number choose the closest factory select resistor value in K OHMS for 311 (if neg.) on R 313 (if pos.). 2. Measure DC voltage of J403A to J403B RGND. Divide 5127 by this number and choose the closest factory select resistor value in K OHMS for R 306 (if neg.) or R 308 (if pos.). D. CHECK ANALOG AUDIO OUTPUT SIGNAL CDP .3 CDP .3 DISPLAY PCB Class - 15 A. INSPECTION -visually check all parts for: solder bridges or splashes, backwards or missing components, component orientation. B. FUNCTION 1. Switch on unit. 2. Insert HDCD disk. 3. Press switch buttons if all are working according to their functions. 4. LED must light during play. 5. Check remote control.
