PDP Module Handling
When there is need to replace a broken PDP module
which is the displaying device from the Plasma display
unit, consider the following:
1. When carrying the PDP module, two persons
should stand at both shorter-edge sides of the
glass-panel and transport it with their palms. Avoid
touching the Flexible Printed Circuits or the chip
tube on the corner of the glass-panel. Handle only
by the surface of the glass panel.
2. When carrying PDP module, watch surrounding
objects, such as tables, and also do not carry it
alone since it may be dangerous and it will be dam-
aged due to excessive stress to the module (glass-
panel).
3. Please do not stand the module with the edge of
the glass-panel on the table since this might result
in damage to the glass-panel and/or flexible print-
ed circuits due to excessive stress to the module
(glass-panel).
Precautions during Servicing
A. Parts identified by the (
#
) symbol are critical for
safety.
Replace only with part number specified.
B. In addition to safety, other parts and assemblies
are specified for conformance with regulations ap-
plying to spurious radiation. These must also be
replaced only with specified replacements.
Examples: RF converters, RF cables, noise block-
ing capacitors, and noise blocking filters, etc.
C. Use specified internal wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
D. Use specified insulating materials for hazardous
live parts. Note especially:
1) Insulation Tape
2) PVC tubing
3) Spacers
4) Insulators for transistors.
E. When replacing AC primary side components
(transformers, power cord, etc.), wrap ends of
wires securely about the terminals before solder-
ing.
F. Observe that the wires do not contact heat produc-
ing parts (heatsinks, oxide metal film resistors, fus-
ible resistors, etc.)
G. Check that replaced wires do not contact sharp
edged or pointed parts.
H. Also check areas surrounding repaired locations.
I. Use care that foreign objects (screws, solder drop-
lets, etc.) do not remain inside the set.
J. When connecting or disconnecting the internal
connectors, first, disconnect the AC plug from the
AC supply outlet.
