bottom side of charger PCB with hint of browning
two components with clear hint of letting out the magic blue smoke.
If anyone can identify the components. The resistor R78 markings have burnt off and the IC12 only has a 67A indication.
Bottom casing, with imprint of magic smoke escaping and moisture which got trapped in charger enclosure.

I thought that said "edible" charger...

That delicious browning is the result of the maillard reaction. Bone apple teeth

as an electrical engineer throw this the fuck out

I hate SMD parts, ya often have to reverse engineer just to know what that 3 - 4 digit part is / was. DIP FTW!

and after all that you can't buy it. So you need to make do with other IC, glued on its back, with tiny wires and few other components added

this one is an obvious google find, and doesn't give any useful ID of the chip.

Basically you need to redraw schematic surrounding that chip and start from there

that reply is almost a direct quote from the first link you posted :-)

this one is new to me and I'll skim right through it.
