SAFETY PRECAUTION
WARNING:
Service should not be attempted by anyone unfamiliar with the necessary precaution on this
receiver.The following are the necessary precaution to be observed before serving this chassis.
1.Since the power supply circuit of this receiver is directly connected to the AC power line ,an
Isolation transformer should be used during any dynamic service to avoid possible shock hazard.
2.When replacing a chassis in the cabinet, always be certain that all the protective devices are put
back in place, such as : non-metallic control knobs, insulating cover,shields, isolation resistor-
capacitor network etc.
3.When replacing parts or circuit boards, disconnect the power cord.
4.When replacing a high wattage resistor (oxide metal film resistor ) on the circuit board, keep the
resistor(1/2in) away from circuit board.
6.Connection wires must be kept away from components with high voltage or high temperature.
7.If any fuse in this LCD TV receiver is blown , replace it with the FUSE specified in the chassis
part list.

PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the chassis have special safety-related
characteristics.These characteristics are often passed unnoticed by a visual inspe-
ction.When replacement parts are required , be sure the service technician uses
replacement parts specified by us that have the same characteristics as the original
part. Unauthorized substitutions may result in fire , electric shock , injury to persons
or other hazards.This LCD TV product should be situated away from heat source such
as radiation,stoves,or other product that produce heat .

－The LCD panel is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
Lamp(CCFL) backlight system. The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive type display operating in the normally black mode. This TFT-LCD has a 32.0 inch
diagonally measured active display area with WXGA resolution (768 vertical by 1366 horizontal pixel array).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes.
Gray scale or the brightness of the sub-pixel color is determined with a 8-bit gray scale signal for each dot,
thus, presenting a palette of more than 16.7M(true) colors with 8Bit.
－The panel has been designed to apply the 8Bit LVDS interface.
－It is intended to support LCD TV, PCTV where high brightness, wide viewing angle, high color saturation,
and high color are important.
