1.1 SAFETY PRECAUTIONS
NOTICE : Comply with all cautions and safety related
notes located on or inside the cabinet and on the chassis.
The following precautions should be observed :
1. When service is required, even though the PDP UNIT
an isolation transformer should be inserted between the
power line and the set in safety before any service is
2. When replacing a chassis in the set, all the protective
devices must be put back in place, such as barriers,
nonmetallic knobs, adjustment and compartment
covershields, isolation resistor-capacitor, etc.
3. When service is required, observe the original lead
dress. Extra precaution should be taken to assure correct
lead dress in the high voltage circuitry area.
4. Always use the manufacture's replacement components.
Especially critical components as indicated on the
circuit diagram should not be replaced by other
Furthermore where a short circuit has occurred, replace
those components that indicate evidence of overheating.
5. Before returning a serviced set to the customer, the
service technician must thoroughly test the unit to be
certain that it is completely safe to operate without
danger of electrical shock, and be sure that no protective
device built into the set by the manufacture has become
defective, or inadvertently defeated during servicing.
Therefore, the following checks should be performed
for the continued protection of the customer and service
6. Perform the following precautions against unwanted
radiation and rise in internal temperature.
· Always return the internal wiring to the original styling.
· Attach parts (Ground, Rear Cover, Shield Case) surely
7. Perform the following precautions for the PDP panel.
· When the front case is removed, make sure nothing hits
the panel face, panel corner, and panel edge (so that
the glass does not break).
· Make sure that the panel vent does not break. (Check
that the cover is attached.)
· Handle the FPC connected to the panel carefully.
Twisting or pulling the FPC when connecting it to the
connector will cause it to peel off from the panel.
8. Pay attention to the following.
· Be sure to wire the fan. If the fan does not work, the
temperature will rise and cause the protection circuit
· When the front case is removed, infrared ray is radiated
and may disturb reception of the remote control unit.
· Pay extreme caution when the front case and rear panel
are removed because this may cause a high risk of
disturbance to TVs and radios in the surrounding.
