Abstract：Color doppler ultrasound equipment is a kind of medical instrument with safety, fast imaging and high diagnostic value,
which has a high social and economic benefits in clinical use. Due to its complex structure and high precision, various failures will
inevitably occur in the process of use. In this paper, the basic structure of GE 730 color doppler ultrasound was analyzed. And the
fault judgment basis and the specific repair method ware expounded in detail through two fault cases. The circuit schematic diagram
was drawn by the actual circuit board, and then the circuit analysis and detection were carried out to determine the fault components,
and finally the maintenance was completed by replacing the electronic components. This maintenance method can achieve the lowest
maintenance cost, save a lot of maintenance expenses for hospitals, and enhance the professional value of clinical engineers.
