HITACHI Magnetic Resonance Imaging Controller Card Troubleshooting starts from circuit board repairing without schematic diagram and the Symptom of HITACHI Magnetic Resonance Imaging malfunctions is : “MR unit error” is reported when the machine starts. The machine does not start normally. Fault check: First check the gradient amplifier of the MRI electronic card unit according…
Fixing Siemens X-Ray Generator Circuit Board Module starts from failure judgement analysis, through fault detection program and measurement methods: first of all, Find by fault detection program is the easist way to access one, under normal circumstances, when Siemens X-Ray Generator fails, most of it can be detected by its own program to determine the…
Troubleshoot Medical Equipment Circuit Board has becoming more and more important in the process of medical equipment maintenance service; In a sense, the use of medical equipment largely depends on the level of development of the hospital and the support of financial resources. At present, medical equipment commonly used in the market and in hospitals…
Rehabilitate Medical Instrument Circuit Board Failure, such as some large-scale equipment such as Computed tomography instrument, Magnetic resonance imaging machines, etc. have their own programs that can detect the approximate root cause of the machine failure, and some circuit board failures can be detected by running the detection program. Printed Circuit Board on-line tester is…
Schneider Electronic Printed Circuit Board Restoration through Integrated Circuit Inspection will go through a series of steps to figure out the root cause; 1st of all, the suspected integrated circuit, according to the instructions of the manual, first check whether there is a signal (waveform) at the input and output ends. If there is no…
Maintain Fresenius Hemodialysis Machine Mainboard is a complete process and we have to repair it without schematic diagram and sometimes the root cause of the failure is not coming from the circuit board itself; A Fresenius hemodialysis machine reports Rinse failure F03 when the heat sterilization counts down to about 26 minutes. Press the Rinse…
Hereby we would like to share an example about Rework Medtronic Ultrasound Machine Motor Control Board: After turning on, the normal interface of Motor Controller Board has been found not able entered. The 60 code is displayed on the total number of controller board display tube. according to the description of original manufacturing there is…
Cardiac Defibrillator Interface Board Repairing starts from the site observation, it was found that the power regulator key indicator light was always on, because the voltage-stabilizing indicator light is always on, it is judged that the voltage button is stuck short-circuited, and the fault is still found after welding the button with a soldering iron.…
Medtronic Covidien E360 Ventilator Analog Board Troubleshooting is mainly aimed at how to restore some electronic PC board failures in the absence of test equipment, lack of technical data such as schematic diagram, gerber file and layout drawing of Printed circuit board from original manufacturer which can be extracted by PCB reverse engineering technique, and…
Rehabilitate NTK Power Module Board of Heidelberg Printing Press normally start from repairing without any schematic diagram which can be acquired through PCB board reverse engineering, the so-called “experience” in the past is difficult to achieve. Although people with deep hardware skills are full of confidence in machine mainboard maintenance, if the method is improper,…
