The reason may be the circuit problem: the circuit problem is a factor that greatly affects the TV work. When the circuit is short-circuited or the voltage is unstable, the TV will turn off and cannot be turned on. When the plug wire of the TV is in poor contact with the socket or either side is damaged, it will also affect the passage of current, resulting in the TV being turned off and turned on again. It is suggested that other household appliances can be used to check the circuit. If it is a circuit problem, check the circuit. If not, check whether the plug wire and socket are in poor contact. Or maybe the TV is burnt out: TV can also cause a sudden strike. There are many reasons for the fire, such as the flickering of the TV switch caused by the unstable circuit, and the long-term heating of the TV without good heat dissipation effect. At this time, the internal components of the TV were destroyed, so everyone had to ask the maintenance master for help. Or the TV is seriously aging: if you use the TV for a long time, the internal parts of the TV will be seriously worn out, and the function will fade or lose, so there is no way to support the normal work of the TV. In addition, if the TV is not used for a long time, the internal parts will be corroded by moisture, resulting in hardware damage and the phenomenon that the mobile phone cannot work. The problem of aging is inevitable. When using TV, it is best to choose regular overhaul and maintenance. If it is the most impossible to repair, it is recommended to replace the TV set.
