Broken Resistor/capacitor - Values on PCB MagSafe 45W-PA-1450 (BOM?)

Tekst:

Hi,

Luis from Germany,

I'm working on a genuine Apple MagSafe 45W PA-1450 charger as it won't charge by system anymore after 4 repairs on the same cord. I have disassembled it once again, I'm getting the right voltage on the output of the PCB.

A visual inspection shows that the big resistor of the high voltage section and the capacitor next to it (see pics) where damaged.

Does any one have the teardown / BOM / PCB component values of these 2 components?

The rest of the components seem to be good. I have the time and the right tools to fix this charger: solder smd, measure (100Mhz scope/multimeter/hot-air/etc.)

Big thanks in advance!
