Example Embodiment

[0035] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0036] The invention provides a method for detecting power feeding of a television, with reference to figure 1 In an embodiment, the method for detecting power feeding of a television includes the following steps:

[0037] Step S110: Obtain the polarization voltage and the DiSEqC communication command transmitted by the satellite tuner; the polarization voltage is the voltage output by the MCU-controlled power supply circuit. Specifically, the MCU outputs an output polarization voltage command to the channel demodulator. Then control the power supply circuit to output the corresponding polarization voltage, or the MCU directly controls the power supply circuit to output the control command of the polarization voltage. The DiSEqC communication command is the command output by the MCU control channel demodulator, specif...

Abstract

The invention discloses a TV feed detection method. The TV feed detection method comprises the following steps of, by a TV, obtaining a polarization voltage transmitted by a satellite tuner; detecting the obtained polarization voltage and a DiSEqC communication command through a detection circuit; and if the detected polarization voltage and the DiSEqC communication command are normal, judging that a power supply circuit is normal. The invention also discloses a TV. After entering a detection mode, the obtained polarization voltage and the DiSEqC communication command are detected by the detection circuit, and the power supply circuit is judged to be normal when the polarization voltage and the DiSEqC communication command are detected to be in normal conditions, so that the TV can detect the state of the power supply circuit at the interior thereof automatically. Accordingly, the workflow of human detection is simplified, the operation time is saved, and the user experience is further improved.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a television set and a method for detecting power supply of the television set. Background technique [0002] The main board receiving circuit of satellite TV is usually divided into three parts: satellite TV tuner, channel demodulator and satellite power supply circuit. When the user is using satellite TV, when the feed circuit is abnormal, or the external satellite receiving antenna is short-circuited or disconnected, the user cannot watch satellite TV. Therefore, the factory needs to detect this when producing satellite TV. Whether the circuit functions of the three modules are normal. The existing detection method simply detects through special external equipment, so the detection efficiency is low. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as ...
