PFC - CM6805BG |

Pretty hopeless without a schematics. J2 can be zero ohms jumper, R18 same as R19. Bottom pair of transistors can be the same, but upper pair is something else. R45 could be 581. Quite a zap. It can have taken with it some others also that have no external marks. |

Hi, Look at the standard diagram - it will be easier to navigate (page 14). https://semiconductors.es/datasheet-pdf/938655/CM6805.html |

Probably the primary switching transistors shorted and the HV (300V+) went everywhere, pretty sure there're lots of other roasted stuff. |
