3 Precaution of Laser Diode
4
SL-CT582VEE

The laser diode in the traverse deck (optical pick-up) may break
down due to potential difference caused by static electricity of
clothes or human body.
So, be careful of electrostatic breakdown during repair of the
traverse deck (optical pick-up).
4.1. Handling of traverse deck
(optical pick-up)
1. Do not subject the optical pick-up to static electricity as it is
extremely sensitive to electrical shock.
2. To protect the laser diode against electrostatic breakdown,
be sure that the short land of the flexible board (FFC board)
should be short-circuit by solder before pulling out the FFC.
Then inserting a short pin or similar object into the tip of the
flexible board.
(Refer to Fig. 4-1.)
3. Take care not to apply excessive stress to the flexible board
(FFC board).
4. Do not turn the variable resistor (laser power adjustment). It
has already been adjusted. (Refer to Fig. 4-1.)
Fig. 4-1.
4.2. Caution when replacing
traverse deck
The new traverse deck short-circuits by the short pin, the foil
(B) and short lands to protect the laser diode against
electrostatic breakdown. Be sure to replace to new one
following procedures.
1. Remove the short pin from the FFC, and then connect it to
the connector.
2. Cut the foil (B). (Refer to Fig. 4-1.) (Take care not to make
contact with cutting point each other.)
3. Unsolder the short lands. (Refer to Fig. 4-1.)
4.3. Grounding for electrostatic
breakdown prevention
4.3.1. Human body grounding
Use the anti-static wrist strap to discharge the static electricity
from your body. (Refer to Fig. 4-2.)
Fig. 4-2.
4.3.2. Work table grounding
Put a conductive material (sheet) or steel sheet on the area
where the traverse deck (optical pick-up) is placed, and ground
the sheet. (Refer to Fig. 4-3.)
Fig. 4-3.
Caution:
The static electricity of your clothes will not be grounded
through the wrist strap.
So take care not to let your clothes touch the traverse deck
(optical pick-up).

1. the waveform or voltage of the focus servo circuit is
correct, and
2. the optical pick-up returns to the normal state by
exchanging the traverse deck.
Follow the below steps when E4 is displayed.
(Cause: Focus gain (FGC) is set beyond the limit.)
· Check if
1. the waveform or voltage of the focus servo circuit is
correct,
2. the focus coil of the optical pick-up is correct (around 8
ohms), and
3. the optical pick-up returns to the normal state by
exchanging the traverse deck.
The followings are the contents of the automatic adjustment
result displays (Self-Check Function).
button.
4. Press the (STOP/TURN OFF) button once.
5. An automatic adjustment result is displayed on the LCD.
Follow the below steps when EF is displayed.
(Cause: All adjustments (TGC, FGC, TBC, FBC) are set
beyond the limit.)
· Check if
1. the optical pick-up returns to the normal state by
exchanging the traverse deck, and
2. the waveform or voltage of the servo ICs are correct.
Note:
It is not always necessary to exchange the traverse
deck when an error message is displayed.
Be sure to check if the circuit is defective or not before
