Patent ID: 8179138

Claim:
A cathode ray tube (CRT) test system for testing a CRT device, the CRT test system comprising: a connecting device, capable of detachably and electrically connecting with the CRT device; a power module, electrically connecting with the connecting device, wherein the power module is used for receiving a power source for supporting operations of the CRT test system; a control module, electrically connecting with the connecting device, wherein the control module comprises a test program, the control module transmits a control signal to the CRT device according to the test program, and the control module further receives a response signal from the CRT device corresponding to the control signal; a first test module, electrically connecting with the control module and detecting the control signal and the response signal; and an illumination module, electrically connecting with the first test module; wherein when the first test module detects that the control signal and the response signal fit in with a first test signal status, the illumination module displays a first light sign; when the control signal and the response signal do not fit in with the first test signal status, the illumination module displays a second light sign.
