Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270°C during
repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.
Notes on Chip Component Replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be
damaged by heat.

SERVICE NOTE
• NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by
the charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
• NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
• To Check the Laser Diode and Focus Search Operation
Open the upper panel. Turn on the power without a disc while
the main board S801 (OPEN) is ON (or T AP802 is shorted). Then,
observe the objective lens and check that the following operations are performed.
1.Scatterd light of laser beams is seen.
2. Check for vertical movements (five) of the objective lens (with
movement of the PU on the inner circumference).

• Moisture Resistant Treatment
Be sure to perform the following work when the cabinet and ring
have been replaced in servicing :
Apply SONY grease SGL-505 (7-662-010-04) to the ring at the
points specified in the figure with an applicator or other means.

• Before Replacing the Optical Pick-Up Block
Please be sure to check throughly the parameters as par the “Optical Pick-Up Block Checking Procedures” (Part No.: 9-960-027-
11) issued separately before replacing the optical pick-up block.
Note and specifications required to check are given below.
• FOK output : IC601 eg pin
When checking FOK, remove the lead wire to disc motor.
When checking FOK value, remove the lead wire to disc
motor.
• RF signal P-to-P value : 0.35 - 0.65 Vp-p
• The repairing grating holder is impossible.
