GE VIVID I system maintainance




First, the failure phenomenon:
The machine starts normally, and after receiving the probe, it prompts an error and the probe is not recognized.

Second, the failure analysis:
The ultrasonic probe does not recognize the power supply that normally considers the probe interface board or supplies power to the probe interface board. The machine configuration diagram shows that there is no high-voltage switch on the interface board of the model, that is, it does not affect the high-voltage output of the DC power supply, so it can pass the detection. The DC output voltage directly determines whether there is a fault in the power supply. After the detection, the machine is found to have no high-voltage output, and it is determined that the DC power supply is faulty.

Third, testing and repair:
Replace the DC-DC power supply, the probe can be recognized normally after the machine is started, and each function resumes normal operation.
