Fault phenomenon
The system is properly starting-up, and a fter entering the ultrasonic working interface, the image appears flickering . T he outside of the image area displays normal.
F ailure analysis
The machine showed an abnormality in the ultrasound image. A corresponding image appeared when the probe was pressed, indicating that the machine's transmitting and receiving parts were functioning properly. Ultrasound probe will emit sound when working. When you switch each probe and put the probe in your ear, listen carefully to the working sound of the probe. It is found that each probe's sound is intermittent during work ing . It was judg ed that the ultrasonic image appears flickering a nd excluded the possibility of the probe failure itself. The probe operating voltage is provided by the DC power module and transmitted to the probe via TI board of the probe interface, so it can be determined that the fault is caused by the DC power supply or the TI board.
T esting and repairing
Replace the TI board and the machine resumes normal operation .
