    Tips: How to deal with the blown fuse of switching power supply?
    In general conditions, blown power fuse indicates problems in internal circuits. The power supply operates under high voltage and current. Voltage fluctuations or surges of power grid often give rise to instant increase of current, which may result in blown power fuse. Users should check whether there is breakdown, open circuit or damage on rectifier diode, HV filtering electrolytic capacitor, and inversion power switch tube at the input end. If the power fuse is blown with no indication of other problems, users need to check components on the circuit board to check whether they are burned out with leaked electrolyte. If there is no such condition, users should check whether there is breakdown or short circuit by multimeter. Users shall not start up the equipment even after finding out and replacing the damaged part, because HV components with malfunctions may damage the newly-replaced part. When dealing with blown power fuse, users must check all HV components on the circuit board before starting up the equipment.
