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.

4. Polaroid Display Cell Defect Specification
In some cases, a panel may have defective cells that cannot be controlled.
These defective cells can be categorized into two types;
(1) Non-lighting or dark cell defect: defect in which the cell is always off
(2) Non-extinguishing or bright cell defect: defect in which the cell is always on
The Polaroid Display Cell Defect Specifications below define the allowed limits for display cell defects and are
used as the criteria in determining whether an LCD panel is replaced.
7 or more defective pixels across the entire LCD screen Polaroid will repair (replace LCD panel) or replace the
TV.

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. Measurement points
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 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
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.
