摘　　要：本文以GE LOGIQ E9两台型号相同但版本不同的彩超设备为例,分析了该设备2例前端故障的维修,并总结了在维修工作中的思路和方法。案例1介绍了设备前后端连接GFI板问题引起的不能开机故障,通过逐一排除法排查出两个22 uf-35 V电容的问题,最终通过更换电容后故障排除;案例2是新版本的LOGIQ E9 GTX发射板故障导致的蓝屏故障,最终通过逐一排查及替换法确定故障来源于MRX板上无法拆卸的元器件,通过更换MRX CW板后故障排除。本文所报道的2例故障情况比较复杂,且为比较少见的前端故障案例,可为医工同行提供一定的借鉴和参考。In this paper,two GE LOGIQ E9 color Doppler ultrasound equipment of the same model but different versions were taken as examples to analyze the maintenance of two front-end faults of the equipment,and summarize the ideas and methods in the maintenance work.Case 1 introduced the fault of starting up caused by the GFI board connection at the front and back ends of the equipment.The problem of two 22 uf-35 V capacitors was found out through the elimination method one by one,and the fault was solved by replacing the capacitor.In case 2,the blue screen of the new version of LOGIQ E9 was caused by the fault of GTX transmitter board.The fault was determined from the components that could not be removed on the MRX board by means of one by one investigation and replacement,and the fault was eliminated by replacing the MRX CW board.The two faults reported in this paper are relatively complex and are relatively rare front-end fault cases,which can provide some reference for medical and industrial colleagues.
