13. Optical Pickup Self-Diagnosis and Replacement
Procedure
13.1. Self-diagnosis
This unit is equipped with the optical pickup self-diagnosis function and the tilt adjustment
check function. Follow the procedure described below during repair in order to perform self-
diagnosis and tilt adjustment effectively. Especially when “NODISC” is displayed, be sure to
apply the self-diagnosis function before replacing with an optical pickup. Replacement of
optical pickup generally requires when the present value of laser drive exceeds 45 (DVD) or 45
(CD).
Note:
Start diagnosis within three minutes after turning on the power (as diagnosis fails when the unit
becomes warm).
