Wiring Diagram Connector Functions Use caution when handling these components. Follow these directions carefully; never use metal instruments to pry apart the cabinet. Remove the 5 screws of main board and 5 screws of IP board. Follow these safety, servicing and ESD precautions to prevent damage and to protect against potential hazards such as electrical shock. For continued safety, do not attempt to modify the circuit board. Disconnect the AC power and DC power jack before servicing. It is essential that service technicians have an accurate voltage meter available at all times.
Check the calibration of this meter periodically. Inspect each lead dress to make certain that the leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the LED TV. Inspect all protective devices such as nonmetallic control knobs, insulating materials, cabinet backs, adjustment and compartment covers or shields, isolation resistorcapacitor networks, mechanical insulators, etc. Leakage Current Hot Check Figure :. Some electrical and mechanical parts have special safetyrelated characteristics which are often not evident from visual inspection.
The protection they give may not be obtained by replacing them with components rated for higher voltage, wattage, etc. Parts that have special safety characteristics are identified by on schematics and parts lists. Product safety is under review continuously and new instructions are issued whenever appropriate. Caution: Before servicing units covered by this service manual, read and follow the Safety Precautions section of this manual.
Note: If unforeseen circumstances create conflict between the following servicing precautions and any of the safety precautions, always follow the safety precautions. Some components are raised above the printed circuit board for safety. An insulation tube or tape is sometimes used. The internal wiring is sometimes clamped to prevent contact with thermally hot components. Reinstall all such elements to their original position. After servicing, always check that the screws, components and wiring have been correctly reinstalled.
Make sure that the area around the serviced part has not been damaged. Check the insulation between the blades of the AC plug and accessible conductive parts examples: metal panels, input terminals and earphone jacks. The insulation resistance between each blade of the AC plug and accessible conductive parts see above should be greater than 1 megohm. Some semiconductor solid state devices can be easily damaged by static electricity. Examples of typical ESD are integrated circuits and some field-effect transistors.
The following techniques will reduce the incidence of component damage caused by static electricity. Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge from your body by touching a known earth ground. Alternatively, wear a discharging wrist-strap device. After removing an ESD-equipped assembly, place it on a conductive surface such as aluminum foil to prevent accumulation of an electrostatic charge.
Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ESDs. Use only a grounded-tip soldering iron to solder or desolder ESDs. Use only an anti-static solder removal device. Do not remove a replacement ESD from its protective package until you are ready to install it.
Most replacement ESDs are packaged with leads that are electrically shorted together by conductive foam, aluminum foil or other conductive materials. Immediately before removing the protective material from the leads of a replacement ESD, touch the protective material to the chassis or circuit assembly into which the device will be installed. Caution: Be sure no power is applied to the chassis or circuit and observe all other safety precautions. Minimize body motions when handling unpackaged replacement ESDs.
