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.

Important Service and Safety Information

PRECAUTIONS FOR USING LEAD-FREE SOLDER

Components within this television use lead-free solder (Sn-Ag-Cu). Whenever soldering, look at the markings on boards and components within the television to determine the correct solder type according 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)

2. Troubleshooting / Flow Charts

Note: Reseat all cables, check fuse by AC plug, perform a clear or reset in factory mode and

retest before ordering parts.

Can’t power on your TV?

This TV is equipped with a safety fuse. In the event of an electrical storm or power outage the safety fuse is designed to protect your TV. If your TV has no power, check the fuse by prying the cover off, following the illustration below. If the fuse is blown, visit your local hardware store and ask for a 4A 250V - 5x20mm Time Lag Fuse (Slow Blow) to replace the fuse.

Having trouble with setting your Parental Controls (V-Chip)?

The factory preset password is 0000. This password must be used first before setting your own personal password. It is recommended that you keep your personal password in a safe place and away from children. In the event you loose your personal password the master password is 8202. The master password overrides all passwords. The master password can’t be changed and should be kept in a safe place away from children.

Having trouble with setting Picture-in-Picture settings? The Picture-in-Picture will not work using Component 1 and Component 2 as the input sources.

Factory Mode Procedure

(1) Power on TV. (2) Press volume up and channel up buttons on the TV simultaneously and release. (3) Power off TV with remote or power button to exit.
