摘　　要：目的本文通过对三例Vivid E9无法开机故障的检修,以期提高同行对该设备的维修能力。方法根据故障现象及电路原理先大体确定故障可能发生的原因,然后将怀疑出现故障的部件替换至其他正常设备测试来定位故障点。结果经过详细分析找出导致无法开机故障的根本原因,如低压电源故障及主板过载等,经过检修故障排除,设备可以正常开机。结论即便是同样的故障现象引起的原因也可能是多样的,但对于无法开机的情况故障大多出在后端,只有充分了解相关电路原理等才能为快速、高效维修提供有力的保证。Objective This paper aims to improve the maintenance ability of the equipment through the maintenance of three cases of Vivid E9 failure. Methods According to the fault phenomenon and circuit principle, the possible cause of fault was determined. Then the parts suspected to be faulty were replaced with other normal equipment to locate the fault point. Results With detailed analysis to find out the root cause of failure to boot, such as low-voltage power supply failure and mainboard overload,etc., the equipment can normally boot after troubleshooting. Conclusion PIt is true that even the same fault phenomenon may be caused by a variety of reasons. However, in the case that the failure cannot be started, most of the faults occur in the back end.Only by fully understanding the relevant circuit principles can provide a strong guarantee for quick and efficient maintenance.
