Abstract:
Abstract PCB faults on X-ray machine occur frequently in our hospital due to humid climate, which lead to many malfunctions such as potentiometer failure, blank screen, lacking KV display, unavailable parameter choosing and disappearing of Er1～Er7 fault code. These malfunctions could be diagnosed and repaired quickly based on analyzing the status of the machine's workflow indicator lights, as well as studying circuit and function principle of the equipment.
