Important Service and Safety Information
Service work should be performed only by qualified service technicians familiar with all safety
checks and these service guidelines:
ELECTRIC SHOCK HAZARD
Always disconnect AC power before servicing!
Never modify any circuit!
Never insert any objects into the holes in the TV case!
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.
NOTICE ABOUT REPLACEMENT PARTS
Many electrical and mechanical parts within LCD or plasma televisions are chosen for their
specific safety characteristics within the overall system. Replacing individual parts with
components rated for higher voltage or wattage can be dangerous!
Replacement parts must always be identical to those originally used in the television. Unauthorized substitute
parts may result in fire, electric shock, or other hazards.
