Safety precautions * General details 1) When providing service, pay attention to the basic wiring and if you see a short circuit, you must replace all parts overheated or damaged by the short circuit. 2) After the service, check if the all elements for protection with insulation layer, insulation paper and shield R-C composite element are well assembled. 3) When not watching the TV for a long period of time, unplug the power cord. 4) Because the high voltage goes through the power (SMPS) when the TV is operating, it is dangerous from electric shock to operate the TV with the back cover open. Repairing must only be done by a repair technician who has adequate knowledge about the high voltage. 5) After completing the service, the repair technician must inspect the following electric current leakage to protect the user from electric shock. 6) Always check if all the internal protection devices are installed. If there is a protection plate, directly install it. 7) After completely assembling the set, plug the AC line cord to the power outlet. Set the power switch to on and then turn it off. Measure the current between the earth (GND) and antenna, metal parts, projected metal parts such as screw heads. The measured current should not exceed 3.5mA. 8) Never change the design or add to the design of the device or electric circuit for this set. If you add to the design, it can cause danger to the safety. Also if you change the design or add to the design, the manufacturer's warranty would be ineffective. 9) If the parts, material or the wiring seem to be overheated or damaged, immediately replace the parts in accordance with the original specification. Always understand the root cause of the overheating or damage and correct the danger factors if possible. 10) Some electric circuit parts and device parts have special safety related characteristics that cannot be judged with the eye. If you replace the parts with a different part with higher voltage, wattage etc, it will lose the safety characteristics and protection function. Therefore you must use the same part as the one installed as much as possible. 11) After the repair, always check if the screw, part and wiring are correctly installed. Check if the adjacent area
