1. Cautions for Backlight Lamp Unit Replacement
The backlight lamps used in the listed Liquid Crystal Display (LCD) modules are
consumables. Follow the included replacement procedures when replacing these
components.
Disconnect AC power before starting the replacement procedure. The high
voltage applied to the backlight lamps produces an electrical shock hazard if
caution is not used when servicing this area.
Backlight lamp units are fragile and caution should be used when handling.
Ferrite cores are attached to the backlight lamp units with double-sided adhesive
tape. Use caution when removing these ferrite cores, as excessive force may
cause damage.
Where possible, replace backlight lamp units in a clean and dust-free environment.
3. Removing INV Cover and INV Board (HOT Side / GND Side)
3-1. Remove the return FFC connected to the INV board.
5. Replacing Lamp Units
5-1. Remove the old lamp units from the lamp clip, and replace them with new ones.
Be very careful not to break the lamp units when detaching/reattaching them. Keep
dust off the units.
Note: The seven lamp direct illumination system uses 14 CCFTs
(Cold Cathode Fluorescent Tubes) to provide backlighting for
the LCD display.
6. Assembly
6-1. Follow the lamp unit removal instructions in reverse order to re-assemble
the backlight lamp assembly. (Section2-5).
Assembly Cautions
Handle fragile lamp units with extreme caution.
Replace lamp units in a dust-free environment.
Do not bend or pinch flat cables when installing the panel unit.
Ferrite core may be damaged even by a slight shock. Attach ferrite cores
very carefully.
Connect the connectors securely to the INV board.
