1. Product Safety Servicing Guidelines
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.
5.Connection wires must be kept away from components with high voltage or high temperature.
6.If any fuse in this LCD TV receiver is blown, replace it with the FUSE specified in the chassis part list.
The lightning flash with arrowhead symbol, within an equilateral triangle is intended to alert the user to the presence of
uninsulated dangerous voltage within the products enclosure that may be of sufficient magnitude to constitute a risk of electric shock.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and
maintenance (servicing) instructions in the literature accompanying the set.

Many electrical and mechanical parts in the chassis have special safety-related characteristics. These characteristics are often passed unnoticed by a visual inspection. 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 and 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.
