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