This phenomenon indicates that the fault may be primary or secondary circuit high-voltage transformer short circuit, therefore, do not increase the fuse size to test machine. Then disconnect the high voltage transformer primary connector energized, not burned insurance. High voltage transformer and secondly stage circuit as shown in the drawings.mLWservice manual download site

The investigation discovered and connected to the high voltage capacitor protection diode (HV6X2P1) has short-circuit breakdown; addition, high voltage silicon stack (HVM12) serious drain tubes were used to replace the model with troubleshooting.mLWservice manual download site
