SERVICE NOTE
CAUTION
Use of controls or adjustments or performance of proce-
dures other than those specified herein may result in haz-
ardous radiation exposure.
Notes on Chip Component Replacement
Never reuse a disconnected chip component.
Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
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.
NOTES ON PICK-UP FLEXIBLE BOARD
The pick-up flexible board in this set is secured to the optical pick-up
with an adhesive tape. Once the tape is removed, an adhering force
becomes weak, and it cannot be reused.
Therefore, if the optical pick-up is replaced, replace also the pick-up
flexible board with a new one.
NOTES ON CLEANING THE OBJECTIVE LENS
Apply CD lens cleaner B-4 (Part No.:J-2501-000-A) to cotton swabs
(narrow type) (Part No.:J-2501-023-A) to be lightly wet. Use a force
(about 5 g) to make the objective lens in contact with the bottom
lightly, and clean the lens by spirals as following below.
Replace the cotton swab and repeat this cleaning two or three times.
SAFETY-RELATED  COMPONENT  WARNING!!
COMPONENTS  IDENTIFIED  BY  MARK  
!
  OR  DOTTED  LINE
WITH  MARK  
!
  ON  THE  SCHEMATIC  DIAGRAMS  AND  IN
THE  PARTS  LIST  ARE  CRITICAL  TO  SAFE  OPERATION.
REPLACE  THESE  COMPONENTS  WITH  SONY  PARTS  WHOSE
PART  NUMBERS  APPEAR  AS  SHOWN  IN  THIS  MANUAL  OR
IN  SUPPLEMENTS  PUBLISHED  BY  SONY.
cotton swabs

2-axis actuator
2-axis cover
slide base
surface of objective lens
Notes:
Do not force to push the objective lens. Otherwise, the plate spring
supporting the objective lens will be bent, causing a deteriorated RF
waveform.
Never touch anything other than the objective lens. Otherwise, a
significant deterioration occurs in the RF waveform.
