  • Patent number: 8179138
    Abstract: A cathode ray tube (CRT) test system for testing a CRT device is disclosed. The CRT test system comprises a connecting device, a power module, a control module, a first test module, and an illumination module. The connecting device detachably and electrically connects with the CRT device; the power module electrically connects with the connecting device; the control module electrically connects with the connecting device; and the control module comprises test program. After the CRT device receives a control signal transmitted from the test program, the CRT device generates a response signal and transmits the response signal to the first test module. 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.
