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)

3. 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, replace with a 4 A 250 V – 5 x 20 mm Time Lag Fuse (Slow Blow) 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.

5. Before Returning This Product to the User
Before returning this product to the user, always perform the following safety checks:
(1) Inspect all wiring to be sure no wires are pinched between the chassis or any metal parts.
(2) Inspect all protective devices for proper installation, including non-metallic controls, insulation materials, cabinet
backs, compartment covers, and shields.
(3)Verify that no shock hazard exists on any part of the chassis, especially any metal components including cable
connection points, chassis hardware, or antennas (if equipped). Use the following procedure:
a.
Plug the AC cord directly into a 120 V AC outlet.
b.
Create a test circuit consisting of a 1.5k ohm, 10
watt resistor paralleled by a 0.15 µF capacitor.
c.
Using an AC voltmeter (sensitivity of 5000 ohm per
volt or higher), measure the voltage drop across
the test circuit between all exposed metallic parts
and a known earth ground. Measurement points
include antenna, metal cabinet parts, screw heads,
and metal knobs or controls.
can vary slightly even between revisions of the
same model, so always conduct a thorough review
of the chassis to locate metal points that a user
may touch.
d.
Any voltage reading of 0.375 Vrms AC (0.25
mArms) or higher indicates a potential shock
hazard. THIS CONDITION MUST BE
CORRECTED BEFORE RETURNING THE
PRODUCT TO THE USER!
e.
Repeat the above checks with the AC polarity
reversed. A non-polarized adapter is required to
reverse the polarity; DO NOT LEAVE THIS
ADAPTER WITH THE USER! Under normal
operation the product must use the proper polarity.

6. Disassembly Procedure
Note: Before disassembly of any part the TV, make sure t he 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.

outlined in the section,
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.
