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 chip component replacement
· Never reuse a disconnected chip component.
· Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
The laser diode in the optical pick-up block may suffer electro-
static 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 HANDLING THE OPTICAL PICK-
UP BLOCK OR BASE UNIT
Laser Diode Properites
· Material: GaAlAs
· Wavelength: 780 nm
· Emission Duration: continuous
· Laser Output Power: less than 44.6 µW*
* This output is the value measured at a distance of 200 mm
from the objective lens surface on the Optical Pick-up Block.
CAUTION
Use of controls or adjustments or performance of
procedures other than those specified herein may
result in hazardous radiation exposure.

CONNECTION AT REPAIR
In repairing this set, connect as follows.
1-2.
FRONT PANEL SETTING
In repairing the front panel, make a setting through the procedure
give below.
Notes:
1. A flat cable and a switch flexible board connected between
liquid crystal module and display board are easily broken, thus
requiring extreme care when handling.
2. As only the removal procedure is given here, see "3. DISAS-
SEMBLY" for details.
Setting:
1. Remove the front panel from control unit.
2. Remove the front panel (ornament) assembly. At this time,
take care not to break the switch flexible board connected to
the display board.
3. Remove the switch flexible board from front panel (ornament)
assembly.
4. Under this condition, attach the front panel to the control unit,
and supply the power.
5. After completion of attachment, turn the power OFF once, and
tilt the liquid crystal module toward the front as shown below.
