    摘要: A method and apparatus for cleaning an electron gun of a CRT wherein said method and apparatus prevents damage to the CRT's during the cleaning process. A protective cap is placed over the pins of an assembled CRT for protecting the pins against damage. The CRT is then lowered into a container that is filled with dielectric-fluid. A socket that includes a central opening is disposed in the container. The pins of the CRT are electrically coupled to the socket. The dielectric-fluid is circulated through the central opening of the socket so as to remove any air trapped between the stem base surface of the CRT and the protective cap. A high voltage electrical current is then selectively applied to the pins for cleaning the electron gun of the CRT.
