SECTION  1
SERVICING  NOTES
The laser diode in the optical pick-up block may suffer electro-
static break-down because of the potential difference generated
by the charged electrostatic load, etc. on clothing and the human
body.
During repair, pay attention to electrostatic break-down 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 emis-
sion, observe from more than 30 cm away from the objective lens.
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.
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur-
ing 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  HANDLING  THE  OPTICAL  PICK-UP
BLOCK  OR  BASE  UNIT
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra-
diation exposure.
This appliance is classified as a CLASS 1 LASER product.
The CLASS 1 LASER PRODUCT MARKING is located on
the rear exterior.
Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.
The following caution label is located inside the unit.
CAUTION
:
INVISIBLE    LASER    RADIATION    WHEN    OPEN    AND
INTERLOCKS   DEFEATED.    AVOID   EXPOSURE   TO   BEAM.

IC502  OF  VIDEO  BOARD
IC502 of the VIDEO board consists of the former type and new
type. The following table shows the differences between the two
types.
Only spare parts for the new type IC502 are supplied.
Units using the former IC502 will not function when replaced with
the new type without performing the following procedure.
Consequently, replace IC502 of units using the former type ac-
cording to the following procedure.
Table of Differences
Replacing Procedure
1. Remove IC402.
2. Solder JW421 and JW422, or short-circuit with a lead wire,
etc.
3. Replace IC502 with a new one.
