Example Embodiment

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Such as figure 1 As shown, the method for automatically testing TV circuit board functions provided in the first embodiment of the present invention includes the steps:

[0028] 101. Connect the test bench containing the TV circuit board under test, the signal conversion and controller module, the control computer, and the signal generator in sequence, and the signal generator output terminal is connected to the test bench input terminal;

[0029] 102. The control computer sends a control command for turning on the TV circuit board under test to the signal conversion and controller module and controls to enter the first test channel, and then forwards the control command to the test through the signal conversion and controller module Station to make the TV circ...

Abstract

The invention discloses an automatic television circuit board function testing method and an automatic television circuit board function testing system. The system consists of a test board for arranging a television circuit board to be tested, a signal conversion and controller module, a control computer and a signal generator which are sequentially connected, wherein the output end of the signalgenerator is connected with the input end of the test board. In the method and the system, test data is transmitted to a computer for comparison test in a network transmission way by adopting a conventional television scheme with network and high-definition multimedia interface (HDMI) functions in combination with a signal conversion and control system consisting of a micro control unit (MCU) to cancel an image acquisition card and save test cost. The scheme provided by the invention supports multi-path HDMI input and further supports the simultaneous test of a plurality of platforms without additional system platforms, so system test difficulties and system cost are reduced.
