Television set failure processing device and television set

Abstract

The invention discloses a television set failure processing device and a television set. The television set failure processing device comprises a power management module, a reset module, a CPU module, a voltage processing module and a key processing module. The power management module outputs a first voltage to supply power when alternating current is supplied to the television set; the reset module automatically generates a reset control signal and outputs the reset control signal to the CPU module for reset; after the CPU module is reset, a response to a key signal output by the key processing module is given, control signals corresponding to a high electric level and a low electric level are output, and therefore the power management module is controlled to output a second voltage with the corresponding voltage value; The voltage processing module monitors the voltage value of the second voltage and automatically generates a reset control signal to control the reset module when the voltage value is smaller than a threshold voltage value; when the key processing module monitors that the time when a reset key is pressed is longer than threshold time, the reset control signal is automatically generated to control the reset module. The television set failure processing device is good in flexibility and stability, simple in structure, low in cost, and high in adaptability and reliability.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a television fault processing device and the television. Background technique [0002] With the development of TV technology, smart TVs are rapidly popularized. Due to the powerful functions and complex structure of smart TVs, crashes will inevitably occur during use. After a crash, the TV is generally restored to normal by means of an AC switch. This is because the general TV has an AC mechanical switch, and it is more convenient to use this method. However, installing an AC mechanical switch will increase the cost, and there are special requirements for the installation position of the AC mechanical switch, which not only increases the difficulty of designing the TV, but also affects its overall appearance. Canceling the AC mechanical switch has become a trend in the development of TV sets. At present, some TVs use a pluggable AC interface instead of an AC mechanical swi...
