Abstract

The invention discloses a method for determining a reason of black screen of a display, which comprises the following steps: when detecting that a player plays a video, snapshooting a display pictureof the display at preset time intervals; judging whether a black screen occurs on the display or not according to the picture obtained by snapshot; when the black screen of the display occurs, obtaining a log file of a player in a set range taking the black screen occurrence time as a reference, the black screen occurrence time being determined according to the time corresponding to the picture obtained by the snapshot; and determining the reason of black screen of the display according to the log file. The invention further discloses a device and a computer readable storage medium, and the problem that in the prior art, the reason for system display black screen is difficult to determine is solved.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to a method, device and computer storage medium for determining the cause of a black screen of a display. Background technique [0002] As broadband enters thousands of households, the application of smart terminals to play videos through the network is becoming more and more extensive. For example, smart TVs use the network to play videos. [0003] However, the system may display a black screen during video playback. The traditional method is to restore the smart terminal to factory settings or unplug the power. In addition, there are various reasons for the black screen of the smart terminal. By restoring the factory settings or Unplugging the power does not necessarily restore it to normal. At this time, developers need to spend a lot of time detecting and locating the cause of the black screen on the smart terminal, which brings troubles to users and develo...
