Note: Before disassembly of any part the TV, make sure the power is OFF, and the power cord is removed from the wall outlet. Allow time for power within all system boards to discharge before you begin disassembly. Never insert any objects into the vent holes in the TV case.

Note: Before returning this product to the end user, you must follow the steps outlined in the section, Before Returning This Product to the User, on page 16. This procedure ensures that the chassis will not cause electric shock.

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.
