It's a full manual. All the parts are in there. I haven't found the problem yett, but I am working on it; hope I can rebuild the part myself. To make it more secure and unbreakable this time. Because the part has failed several times before and costs a lot to let it be repaired.
Thanks so much for this rich illustrated and parted manual.

I downloaded the document. The manual was complete, well scanned and everything was legible. I could zoom in see what I needed to know. There's not much more that you can ask.

Ottima qualità grafica e completo nelle notizie. Costo abbastanza contenuto.

Laser Current ABEX Test Disc DC Voltmeter Check TCD-784 across R101 on CD P.C.B.
1. Turn ON the power and load a test disc. (To load the test disc, press the Open/Close button of the CD Player.) 2. Play back the test disc and calculate the current flowing into R101 on the CD P.C.B. Ass'y from the following formula. Voltmeter Value I(Measured) = = oo.o mA R101 (10 Ohms) Example: 510.3 (mV) I(Measured) = 10 (ohms) 3. Check that the I(Measured) obtained in 2 and the rated current value (IOP) shown on the label are almost the same. [How to read IOP on the label] The shaded "OOO" on the label shows the IOP. If "OOO" is 475, the IOP is 47.5mA. NOTE: The calculated current (I(Measured)) = 51.03 mA

should be in a range of 30 to 60 mA. If the value is large, the pickup will be defective. 4. Stop the test disc.
2 EFM Signal Adjustment ABEX Test Disc Oscilloscope TCD-784 between pin 1 of TP101 and GND on CD P.C.B. � 1. Play back the first track of the test disc. 2. Be sure that the peak-to-peak value of the EFM waveform is approx. 1V.
Approx. 1Vp-p
Oscilloscope Setting: AC Mode, 0.2 V/div, 0.5 µs/div 3. Stop the test disc and eject it.
