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. PRECAUTIONS FOR USING LEAD-FREE SOLDER Components within this television use lead-free solder (Sn-Ag-Cu). Look at the markings on board and components within the television to determine the correct solder type and match to the table below: 5 LEAD-FREE (Pb-Free) CATEGORIES The following categories are meant to describe the Pb-free 2nd level interconnect terminal finish, component material, and/or the solder paste/solder used in board assembly: e1 - SnAgCu (shall not be included in category e2) e2 - Sn alloys with no Bi or Zn excluding SnAgCu e3 - Sn e4 - Precious metal (e.g., Ag, Au, NiPd, NiPdAu) (no Sn) e5 - SnZn, SnZnx (no Bi) e6 - contains Bi e7 - low temperature solder (. 150 °C) containing Indium (no Bi) e0, e8, e9 symbols are unassigned at this time. When repairing components soldered with lead-free solder, ONLY use lead-free solder that matches the symbol on the component. Using conventional lead solder may lead to damage or a short, which could result in fire, electric shock, or other hazards. Because the melting point of lead-free solder is higher than conventional lead solder, observe the following guidelines when soldering with lead-free solder: (1) Always use a dedicated soldering bit for different types of solder. If a different type of solder comes in contact with a lead-free solder bit, subsequent solder joints will no longer be lead free. Always clean the soldering bit after every use. (2) Keep the soldering bit in contact with the just long enough to confirm a good solder joint. Leaving the bit in contact with parts for an extended period may damage the components. (3) Because lead-free solder contains a higher concentration of tin, the tip of the soldering bit may be easily corroded or damaged. Do not leave the bit powered on for extended periods. When the tip of the soldering bit is blackened during use, clean the bit with steel wool or fine sandpaper. (0) 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. Table of Contents 1.
