Preparation of Servicing
The laser diode used for a pickup head may be destroyed with external static electricity.
Moreover, even if it is operating normally after repair, when static electricity discharge is
received at the time of repair, the life of the product may be shortened.
Please perform the following measure against static electricity, and be careful of destruction
of a laser diode at the time of repair.
• Place the unit on a workstation equipped to protect against static electricity, such as
conductive mat.
• Soldering iron with ground wire or ceramic type is used.
• A worker needs to use a ground conductive wrist strap for body.
Servicing Environment
1. This LCD TV should be used only with the power source type identified on the package
and on the user's guide.
2. Service the LCD TV in a room with low humidity and free of dust.
3. Place the LCD TV on a stable, level surface. Subjecting the LCD TV to a drop or sharp
impact may cause severe damage to thin glass, plastic surface materials, and internal
components.
4. If necessary, clean the LCD TV with a slightly damp cloth using clean water. Disconnect
the LCD TV from the power source before cleaning. Do not use ammonia-based
cleaning products.
5. In the event that the powered LCD TV rapidly heats, or emits unusual smells or noises,
immediately disconnect the unit from the power source.
6. To avoid electrical hazard, make sure that the LCD TV is fully assembled—the casing
closed and all the screws tightened completely—before plugging it in for testing.
7. The LCD TV's internal components may be damaged by electrostatic discharge (ESD).
Carry out repairs in an ESD-protected workshop. If no such workshop is available,
wear an antistatic wrist strap or touch a highly conductive metal object.
8. Before opening the housing, disconnect the LCD TV from all power sources and
remove all peripheral cables. If the LCD TV has not been disconnected from the power
outlet before being opened, there is a danger to life through electric shock. There is
also a risk of damage to the components.
