10 SELF-DIAGNOSIS FUNCTION AND SERVICE MODE
10.1. Optical Pickup Breakdown Diagnosis
As a new feature, this unit has an “optical pick-up problem diagnosis function” and “a tilt adjustment confirmation function” built in.
Use the following procedure to efficiently determine the problem and adjust tilt. If "NO DISC" is displayed, before exchanging the
optical pick-up, carry out problem diagnosis first. If the present laser driving current is over 63, the optical pick-up may need to be
exchanged.
Note:
Carry out diagnosis within 3 minutes of turning the unit on. (The player's current can increase as it warms up, so turn the unit off
and allow it to cool down before diagnosis.)
