Chosen Solution
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!
@lurgaci Apple may not but iFixit does. After all, the purpose of this website is to empower others to fix their devices. Good thing I am a hoarder and keep stuff after I tear it down :-)This is the part you are looking for
After checking it with my meter it shows to be a 0.24ohm resistor. The capacitor shows 74 uF and that is mounted to the board. Can’t get to my ESR tester right now but that should still work out for you.
Sorry Apple doesn’t offer parts or any info for their chargers. Frankly, given the high voltages and the risks of fire I don’t recommend trying to fix them. Besides the personal risks you can also damage your system as well here!
