– 46 –

If the level is not normal, check around pins 27~29 on IC1.

1. Is focus servo activated ? (Waveform drawing 46-2)

Pins 1~11 on IC1
Check the laser diode driver Q3 peripheral circuit.
Focus error circuit (pins 20 and 21 on IC1)

When a disc is loaded, start playback operation.

2. Does DRF change from "L" to "H" ?

Is the disc rotating ?

3. Is the HF waveform normal ? (Waveform drawing 46-3)

Check the spin system.

If the disc is spinning and a HF waveform is generated,
DRF will go H.

Figure 46-1

Check the laser diode driver Q3 peripheral circuit.

(1) Focus-HF system check.

Although a CD is inserted and the cover is closed, "NO
DISC" is displayed.

1. Does the pickup move to the PICKUP-IN Switch (SW4)

position ?

Sled motor (M2).

Press the OPEN/CLOSE switch (SW1) without inserting a
disc, and try starting the playback operation.

2. Does the focus (lens) move up and down ?
(Waveform drawing 46-1).

Check the focus peripheral circuit.

3. Is the laser lit ?

Spindle motor (M1).

4. Is the turntable rotating ?
