Zusammenfassung: | The utility model discloses an LED television test circuit and a test device, the LED television test circuit comprises a light-emitting module current test circuit, the light-emitting module current test circuit is provided with a plurality of first resistors and first contacts arranged in one-to-one correspondence with the plurality of first resistors; one end of each first resistor is used for being electrically connected with a preset power source, the other end of each first resistor is used for being electrically connected with a corresponding preset light bar, and each first contact is electrically connected to the two ends of the corresponding first resistor. And each first contact is used for connecting the positive electrode and the negative electrode of a meter pen or connecting a display. The LED television test circuit disclosed by the utility model can solve the technical problems that the current test method for the television light-emitting light bar is low in efficiency and easily causes equi |
