SAFETY PRECAUTIONS
Leakage Current Hot Check (See below Figure)
Plug the AC cord directly into the AC outlet.
Do not use a line Isolation Transformer during this check.
Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitor between a known good earth
ground (Water Pipe, Conduit, etc.) and the exposed metallic parts.
Measure the AC voltage across the resistor using AC voltmeter with 1000 ohms/volt or more
sensitivity.
Reverse plug of the AC cord into the AC outlet and repeat AC voltage measurements for each
exposed metallic part. Any voltage measured must not exceed 0.75 volt RMS, which is,
corresponds to 0.5mA.
In case any measurement is out of the limits specified, there is possibility of shock hazard and
the set must be checked and repaired before it is returned to the customer.

!! Important Safety Notice !!
Many electrical and mechanical parts in this chassis have special safety-related
characteristics.
These parts are identified by in the Schematic Diagram and Replacement Parts List.
It is essential that these special safety parts should be replaced with the same components
as recommended in this manual to prevent Shock, Fire, or other Hazards.
Do not modify the original design without permission of manufacturer.

SERVICING PRECAUTIONS
CAUTION!!
Before servicing receivers covered by this service manual, read and follow the SAFETY
PRECAUTIONS on page 3 of this publication.
General Servicing Precautions
1.Always unplug the receiver AC power cord from AC power source before;
ⓐRemoving or reinstalling any component, circuit board module or any other receiver assembly.
ⓑDisconnecting or reconnecting any receiver electrical plug or other electrical connection.
ⓒConnecting a test substitute in parallel with an electrolytic capacitor in the receiver.
CAUTION!! A wrong part substitution or incorrect polarity installation of electrolytic capacitors
may result in an explosion harzard.
2.Do not spray chemicals on or near this receiver or any of its assemblies.
3.Do not defect any plug/socket voltage interlocks with which receivers covered by this service
manual might be equipped.
4.Always connect the test receiver ground lead to the receiver chassis ground before
connecting the test receiver positive lead. Always remove the test receiver ground lead last.
5.Do not connect the test fixture ground strap to power supply heatsink in this receiver
Electrostatically Sensitive(ES) Devices
Some semiconductor(solid state) devices can be damaged easily by static electricity. Such
components commonly are called Electrostatically Sensitive(ES) Device.Examples
Circuit Board Foil Repair
Excessive heat applied to the copper foil of any printed circuit board will weaken the adhesive
that bonds the foil to the circuit board causing the foil th separate from or “lift-off” the board.
The following guidelines and procedures should be flollowed whenever this condition is
encountered.
At IC Connections
To repair a defective copper pattern at IC connections use the following procedure to install a
jumper wire on the copper pattern side of the circuit board.(Use this technique only on IC
connections.)
1.Carefully remove the damaged copper pattern with a sharp knife.(Remove only as much
copper as absolutely necessary.)
2.Carefully scratch away the solder resist and acrylic coating(if used) from the end of the
remaining coopper pattern.
3.Bend a small “U” in one end of a small guage jumper wire and carefully crimp it around the IC
pin.
4.Route the jumper wire along the path of the out-away copper pattern and let it overlap the
previously scraped end of the good copper pattern. Solder the overlapped area and clip off any
excess jumper wire.

Note!! :
ⓐIf the set is cold, there may be a small “flicker” when the set is switched on. This is
Normal, there is nothing wrong with the set.
ⓑif possible, use the VESA 640x480 PC video mode to obtain the best image quality for
your LCD TV. If used under the other resolutions, some scaled or processed pictures may
appear on the screen.
ⓒsome dot defects may appear on the screen, like Red, Green or Blue spot. However, this
will have no impact or effect on the monitor performance.
