9.2.4. Optical Pick-up Self-Diagnosis
The optical pickup self-diagnosis function and tilt adjustment check function have been included in this unit. When repairing, use
the following procedure for effective self-diagnosis and tilt adjustment. Be sure to use the self-diagnosis function before replacing
the optical pickup when "NO DISC" is displayed. As a guideline, you should replace the optical pickup when the value of the laser
drive current is more than 55.
Note:
