Abstract

The invention is applicable for the technical field of televisions, and provides a method for turning on a television and the television. The television comprises a master system and a power module, and also comprises a detection circuit and a standby management microcontroller, wherein the detection circuit is used for detecting a signal input status of a signal source input port of the television in real time when the television is in a standby mode, and transmitting a detection result to the standby management microcontroller; and the standby management microcontroller is used for controlling the power module, and controlling the power module to execute a power-on operation when the detection circuit detects that a signal is input at the signal source input port. The input signal source is switched to the signal source input port having signal input after the television is started. The technical scheme brings convenience and simplicity to a user to operate the television and meets the requirements of the user.

Description

technical field [0001] The invention belongs to the technical field of televisions, and in particular relates to the technology of controlling the television on and off. Background technique [0002] Existing TVs can receive signals input from multiple sources, such as video and audio signals input from a set-top box, video and audio signals input from a DVD player, etc., which creates a problem: when the input source changes, it needs to switch TV to the input port corresponding to the current source. [0003] In order to simplify the user's operation, the existing TV can automatically switch according to the change of the signal source. The realization principle is: the TV system detects in real time whether there is signal input at each source input port, such as judging the line and field synchronization pulse of the video signal. to confirm whether there is a signal input. When the TV system detects that a certain input port has a source input, it will automatically j...
