When servicing an LCD or plasma TV, always observe the following safety guidelines:
• Wear a grounding (ESD) wrist strap, and use a grounded or dissipative work mat.
• Use a stable and strong work surface that is large enough to hold components you might remove.
• When removing components that are attached with a cable, unplug the cable before removing the
screws to avoid damaging the cable.
• Use a magnetized screwdriver for removing screws.
• To help keep track of screws, place each component’s screws next to the component on your work
surface.
ELECTROSTATIC DISCHARGE (ESD)
Components inside an LCD or plasma TV are sensitive to static electricity. Before servicing the TV, follow these
guidelines:
• Avoid static-causing surfaces such as carpeted floors, plastic, and packing foam.
• Remove replacement components from their antistatic bags only when you are ready to use them. Do
not lay components on the outside of antistatic bags because only the inside of the bags provide
electrostatic protection.
• Always hold components by their edges. Avoid touching the edge connectors. Never slide components
over any surface.
• Wear a grounding wrist strap (available at most electronics stores) and attach it to a bare metal part of
your workbench or other grounded connection.
• Touch a bare metal surface on your workbench or other grounded object before touching any
components.
