As I said at the beginning of the post, I don't have backlighting, the USB-C ports don't work, and the keyboard and trackpad don't work.
You didn't answer my question. I asked: If I do a swap, can you tell me which components to swap?
I have a screen, but I don't get any display when I connect the Mac externally. I tried connecting and disconnecting the screen cable.
I tried closing the cover, but got the same result.
Hello,
I have an A2681, it got wet, the customer brought it back to another store and then to us.
I found oxidation on the backlight area, next to UP950, UR630, and UR600.
We also found some oxidation on UF 350. I cleaned it and replaced it.
Before, it wouldn't start, but I replaced UR630...
The computer consumes 20v and 1a, so it's normal consumption, but I have no display and the battery is disconnected. I tried the chassis and it's fine. I put a another motherboard and everything works.
LA-300: 1.35V ok
LA-350: 0.9V ok
LA-640: 0.9V ok
LA-650: 0.9V ok

I have a MacBook that won't turn on (1).

1V25_S2 no value and I have 260 ohms and it is not short-circuited
and I have the same value before changing U7700 and U8100
I tried but nothing works, it does not enter DFU mode
We replaced U8100 and U7700.
PP1V5_UPC0_CORE OK
PP3V3-UPC06_LDO OK
PPVBUS_USBC0 5V
USBC0_CC1 1.6V
RF403 I have 0.5V
It does exactly the same thing.
We connected it to the computer and it is not detected in DFU mode.
Afterwards, the computer stays at 5V and does not switch to 20V.
What is...
A2338 remains at 5V and 0.018A (The motherboard has not been damaged by water; it is in perfect condition.)
I checked UF500 and UF400; both are fine. We checked them on another motherboard, and they output 20V.
I flashed UF260, but nothing changed.
We even replaced U5200, but nothing changed...
