This is the second Manual I have ordered from owner-manuals, I give it five stars because it is exactly what I expected given the age of the equipment. So the contents look a bit aged and the pictures a bit grainy, it fulfills my needs and I am glad I can still get hold of them.

thank u so much for this manual that was so cheap that i thought it was a scam but i gambled anyway because it was too good of a deal to pass up and behold,the manual has everything and details of everything even the screws and im still amazed and very happy with my manual .so take my word and jump on it before they realize how cheap they selling thier manuals..thank you so much for taking time to read my thoughts

Figure 1 1. Does the pickup move to the PICKUP-IN Switch (SW1A) position? No Sled motor (M2A).
Yes 2. Does the focus (lens) move up and down? (Waveform drawing Figure 1)
No
Check the focus peripheral circuit.
Yes 3. Is the laser lit? No Check the laser diode driver Q1 peripheral circuit.
Yes 4. Is the turntable rotating? No Spindle motor (M1A).
When a disc is loaded, start playback operation.
1. Is focus servo activated? (Waveform drawing Figure 2)
No
Pins 7~11, 13,19 and 20 on IC1 Check the laser diode driver Q1 peripheral circuit.
Yes 2. Does DRF change from "L" to "H"?
No
Is the disc rotating?
No
Check the spin system. If the disc is spinning and a HF waveform is generated, DRF will go H.
Yes 3. Is the HF waveform normal? (Waveform drawing Figure 3) No If the level is not normal.
