2. If there is no lightning protection device installed on the TV outdoor antenna during thunderstorms, it is easy to introduce lightning into the TV. The machine will instantly generate high temperature, which may cause fire or even explosion.
3. If the TV exceeds the service life (the current TV set has a service life of 8 years), the safety factor will continue to decrease as the service life approaches. This kind of TV is prone to spontaneous accidents such as spontaneous combustion or explosion.
