The TV is a very complicated machine. As long as one of the components or welding points fails, the whole machine will not work normally or at all. Therefore, the maintenance of the TV is very important. Good maintenance can avoid major accidents and reduce the damage to the TV.
It should be checked whether the power supply voltage of the TV matches the local power grid voltage.
2. Choose an appropriate location
Because the structure of the house reflects the TV signal, the signal strength is different at different locations in the same room. Therefore, when possible, an appropriate location should be selected to make the TV signal the strongest and the ghost to be the smallest, so as to improve the viewing effect.
The signal is weak, and the indoor antenna has little effect. Consider choosing an appropriate outdoor antenna; to prevent lightning strikes, you should install a lightning arrester or a line switch.

Please turn off the power and unplug it immediately. When it is confirmed that it is abnormal, do not continue to use it. Please ask a professional for inspection and repair.

Before the thunderstorm arrives, unplug the power plug and antenna to prevent lightning strikes. According to the national "Three Guarantees" regulations, the lightning striker is not covered by the free warranty.
