Here are circuit diagrams
if there is damage, I recommend using this part of the
a complete list of circuit boards and components
Disc Sensor Adjustment Be sure to perform this adjustment after sensor adjustment in MECHANICAL ADJUSTMENT. Connection:
MAIN board CN506 D.S GND T.P D.S: Pin 1 T.P: Pin 3 GND: Pin 2 oscilloscope
5. Rotate the DISC/CHARACTER knob in the counterclockwise direction and the disc table starts to rotate in the same direction. Check that the waveform at this time is the same as that in step 4. If larger by a considerable extent, rotate the DISC/CHARACTER knob in the clockwise direction and the disc table starts to rotate in the same direction. Repeat from step 4. 6. Rotate RV501 of the MAIN board and adjust so that the H and L portions of the D.S waveform become the same.
Waveform:
D.S
D.S
Adjust so that these widths become the same.
Adjustment Location: MAIN board
P.T
1. Connect the oscilloscope to Pins 1, 2, and 3 of CN506 of the MAIN board. 2. Check that no discs are loaded in the unit. 3.
