NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic 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 emission, 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 damaged by heat.
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.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation 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.

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 according to the following procedure.
Table of Differences

JW421, JW422 NO MOUNT MOUNT
IC402 MOUNT NO MOUNT
R413, 421, 422 MOUNT NO MOUNT
X401 MOUNT NO MOUNT
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.
