#1 Ładowarka ISY – Zwarcie Vcc i GND

Witam, Moja ładowarka nagle przestała ładować. Po rozebraniu jest zwarcie pomiędzy +5V a GND i dioda SK34 chyba też zwarta, widać że dwa rezystory się smażyły w miejscach R5 i R6 obudowa w tym miejscu była okopcona, Czy mógłby mi ktoś pomóc co mogę jeszcze sprawdzić ? pozdrawiam

Hello!

It is bad primary controller chip U1 (SD8583S) and shunt resistors R5 and R6 (probably it is 2.47Ω, but I'm not 100% sure). It also could be bad fusible resistor FR1 and bridge rectifier BM1, so check it.
At secondary it could be bad rectifier diode SK34, so check it out from circuit.
