In severe cases, the TV may even be burned. Therefore, it is recommended that the user should dehumidify the room in time to maintain a relatively dry environment. Especially when lightning lightning, it is best to turn off the TV and unplug the power supply, because the lightning voltage is very high when the lightning strikes, and the voltage of the TV electronic components is relatively low, the induced voltage is introduced from the power line, and some of the electrons are instantaneously penetrated. element.
