CHECKS PRIOR TO PARTS REPLACEMENT AND ADJUSTMENTS

Before performing repairs, perform the following checks to determine the faulty locations up to a certain extent.
Details of the procedures are described in “5. Electrical Adjustments”.

Laser power check
(See page 25)

Temp check
(See page 25)

Measure if unsatisfactory:

• Clean the optical pick-up
• Adjust again
• Replace the optical pick-up

• Replace the optical pick-up

• Check for disconnection of the circuits around
D101 (BD board)
• Check the signals around IC101, IC151, CN102,
CN103 (BD board)

Note:

The criteria for determination above is intended merely to determine if satisfactory or not, and does not serve as the specified value for adjustments.
When performing adjustments, use the specified values for adjustments.

Criteria for Determination

(Unsatisfactory if specified value is not satisfied)

• 0.9 mW power

Specified value : 0.84 to 0.92 mW

• 7.0 mW power

Specified value : 6.8 to 7.2 mW

lop (at 7mW)

• Labeled on the optical pickup

Iop value ± 10mA

• Unsatisfactory if displayed as T=@@ (##) [NG”

NG
(@@, ## are both arbitrary numbers)
