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 68, 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.)

Cautions to be taken when replacing the optical pickup
The optical pickup may break down due to the static
electricity of human body. Take proper protection measures
against static electricity before repairing the parts around
the optical pickup. (See the page describing the
PREVENTION OF STATIC ELECTRICITY DISCHARGE.)
1. Do not touch the areas around the laser diode and
electricity of human body. Take proper protection measures
against static electricity before repairing the parts around
the optical pickup. (See the page describing the
PREVENTION OF STATIC ELECTRICITY DISCHARGE.)
1. Do not touch the areas around the laser diode and
actuator.
2. Do not judge the laser diode with a tester. (The tester
will be damaged easily.)
3. It is recommended to use a destaticized soldering iron
for short-circuiting or removing the laser diode.

4. Solder the land of the flexible cable in the optical pickup.
Note:

•
• When using a soldering iron which is not
destaticized, short-circuit the terminal face of the
flexible case with a clip. After that, short-circuit
the land.
