1故障现象点片照相有X线输出、透视造影监视器无显示。2故障分析与检修从上述现象可知,主机照相正常,说明故障发生在影像增强器或监视器上。打开增强器后罩,拆下增强器高压电源供电板ICV-009。从电路板上直观检查未发现问题,用万用表测量怀疑件,发现Q1、Q2管均已击穿短路,用同 1 symptoms X-ray point film camera output, fluoroscopy monitor no display. 2 fault analysis and maintenance From the above phenomena we can see that the host camera is normal, indicating that the fault occurred in the image intensifier or monitor. Open the enhancer rear cover and remove the booster high voltage power supply ICV-009. Visual inspection from the circuit board found no problems, using a multimeter to measure suspicious pieces and found Q1, Q2 have been punctured short-circuit, with the same
