Schematics

VA0 PAL

CD Adjustments

CD p/n 610-5679-20, -21

Adjustment Preparation
Apply markings to the positions of the variable resistors before adjustment. If the adjustment are out of the specifications, the following symptoms may occur.
[Focus gain]
If the focus adjustment is too low the pickup lens will not be able to focus properly and the disk will not rotate. If the adjustment is too high portions of a track may be skipped and noise will increase.
[Tracking gain]
If the tracking adjustment is too low the drive is more susceptible to shocks or bumps, portions of a track may be skipped or the disk time counter may stop. If the adjustment is too high the pickup lens may oscillate leading to unstable or distorted sound. The focus and tracking adjustments are done so as to mutually satisfy conflicting characteristics.
6-3. Test equipment and tools necessary for adjustment
  1. Oscilloscope
  2. DC voltmeter
  3. Non-metallic adjustment screwdriver
  4. Test CD (A-BEC TCD-792A)
6-4. CD Drive Unit Adjustment Procedure
6-4-1. FE (Focus Error) bias adjustment and focus gain adjustment
  1. Connect the oscilloscope to test point FE IN as shown in Fig. 6-2.
  2. Turn the power switch on and set the CD drive to the stop mode.
  3. Adjust RI 14 (FE bias) so the DC voltage at the test point (FE IN) is 0V.
  4. Play the first track of the test CD and adjust R111 (Focus gain) so the DC voltage is -7mV.
6-4-2. FE balance and tracking gain adjustments
  1. Connect the oscilloscope to test point BP IN as shown in Fig. 6-3.
  2. Turn the power switch on and play the first track of the test CD.
  3. After play has begun, connect the TEST pin to GND.
  4. Adjust Rl04 (FE balance) so the center voltage of the waveform is 0V.
  5. Adjust R113 (tracking gain) so the amplitude of the waveform is 0.4V as in Fig. 6-4.
