Unpacking and Repacking the Plasma Panel
Panel Replacement Precautions
Handling
Use extreme care when handling the Plasma Display Panel. Due to the size and
fragility, it is recommended that two individuals handle the Plasma Panel to avoid
accidental damage.
The glass used in the plasma panel is thin, and its structure is extremely susceptible to
impact. Rough handling of the unit can crack the glass or cause pixel defect errors. Be
sure to transport the panel in the upright position. The unit is designed to absorb force
vertically not horizontally.
Numerous flexible printed leads with extremely soft structure are used around the panel.
Be very careful during handling not to damage these by pulling, bending, or subjecting
them to excessive force. When inserting a ribbon cable into a socket, verify that the
cable is straight. Angled insertion can create an electrical short circuit and permanently
damage the panel.
High Voltage
Plasma Display Panels use a high voltage power supply. Disconnect the AC from the
unit and wait one minute for the voltage to dissipate.
Static
Anti-static measures should be applied, especially when connecting and disconnecting
the ribbon cables.
Scratches
A protective sheet is attached to the back of the replacement panel to prevent scratches
and accumulation of debris. Be sure to remove the protective sheet and wipe the
surface with a soft cloth before installation.
Assembly
A low torque setting is recommended when installing screws in the panel assembly.
Preparation of the new panel
1) The replacement panel is shipped in a special
shipping crate. Retain this crate to return the
defective panel.
