Procedure (DVD Section)
9.1. 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 "NO DISC" 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 55.

Start diagnosis within three minutes after turning on the power (as
diagnosis fails when the unit becomes warm).
