Notes on safe handling of the plasma display
2. 1
Notes to follow during servicing
The work procedures shown with the Note indication are important for ensuring the safety of the
product and the servicing work. Be sure to follow these instructions.
product and the servicing work. Be sure to follow these instructions.
Before starting the work, secure a sufficient working space.
At all times other than when adjusting and checking the product, be sure to turn OFF the main
POWER switch and disconnect the power cable from the power source of the display (jig or the
display itself) during servicing.
POWER switch and disconnect the power cable from the power source of the display (jig or the
display itself) during servicing.
To prevent electric shock and breakage of PC board, start the servicing work at least 30 seconds after the
main power has been turned off. Especially when installing and removing the power supply PC board
and the SUS PC board in which high voltages are applied, start servicing at least 2 minutes after the
main power has been turned off.
main power has been turned off. Especially when installing and removing the power supply PC board
and the SUS PC board in which high voltages are applied, start servicing at least 2 minutes after the
main power has been turned off.
While the main power is on, do not touch any parts or circuits other than the ones specified.
The high voltage power supply block within the PDP module has a floating ground. If any
connection other than the one specified is made between the measuring equipment and the high
voltage power supply block, it can result in electric shock or activation of the leakage-detection
circuit breaker.

When installing the PDP module in, and removing it from the packing carton, be sure to have at least two
persons perform the work while being careful to ensure that the flexible printed-circuit cable of the PDP
module does not get caught by the packing carton.

When the surface of the panel comes into contact with the cushioning materials, be sure to confirm
that there is no foreign matter on top of the cushioning materials before the surface of the panel comes
into contact with the cushioning materials. Failure to observe this precaution may result in the surface
of the panel being scratched by foreign matter.

Be sure to handle the circuit PC board by holding the such large parts as the heat sink or transformer.
Failure to observe this precaution may result in the occurrence of an abnormality in the soldered areas.

Do not stack the circuit PC boards.
Failure to observe this precaution may result in problems resulting from scratches on the parts, the
deformation of parts, and short-circuits due to residual electric charge.
deformation of parts, and short-circuits due to residual electric charge.
Routing of the wires and fixing them in position must be done in accordance with the original routing
and fixing configuration when servicing is completed.
and fixing configuration when servicing is completed.
All the wires are routed far away from the areas that become hot (such as the heat sink). These
wires are fixed in position with the wire clamps so that the wires do not move, thereby ensuring
that they are not damaged and their materials do not deteriorate over long periods of time.
Therefore, route the cables and fix the cables to the original position and states using the wire
clamps.

Perform a safety check when servicing is completed.
Verify that the peripherals of the serviced points have not undergone any deterioration during
servicing. Also verify that the screws, parts and cables removed for servicing purposes have all
been returned to their proper locations in accordance with the original setup.
