•Hot caution mark
This mark appears on parts of the circuit board to
indicate that they become hot. When the display is
turned on, or even after a short time after the power is
turned off, touching such parts may cause burns. Before
working on such parts, be sure to remove the power
cord, and do not touch them.
•

.
•
Disassembly and assembly are basically carried out with the monitor screen facing
down. To protect the screen from damage, insert pole made of styrofoam between
the display and the workbench (see page 7).
•
Be sure to use a proper screwdriver bit that fits to the screw head.
•
Follow the tightening torque specified in this manual when fastening screws.
•
Use a commercially-available antistatic wrist strap when touching a circuit board.
•
Connect and remove connectors carefully to avoid damaging connectors and cables.
•
Return all components and wiring to their original conditions. For safety reasons,
some components use insulation material, such as tubing and taping, while others
are mounted off the printed circuit board. Internal wires are run in a way to prevent
them from making contact with heat-source and high-voltage components (such as
by using clamps). Be sure to return them to their original conditions.
•
Do not disassemble any parts not listed in the disassembly instructions of this
service manual. Also, do not disconnect cables and connectors.
•
Wear gloves for preventing you from injury when removing a frame.
