Hello, I will start this by saying I am VERY new to logic board repair, I know basics and learn best by doing but have found this difficult as I can't find my exact problem and just chunks of it which makes things hard to track for me.
It's a Macbook Air 2019 A2159 820-01598.
It was apperantly used for 3 months then randomly stopped, I was asked to repair it a year or so later as Apple wanted to charge too much.
It started off with 5v 0amps, I tracked down a problem with U7000, U9080 and U6903. When I replaced these I started getting 5v and 0.340A. I can't seem to get any further than this and have gotten a bit confused in the process, I can't remeber exactly what lead me to U7000 as this was about a month ago while waiting for new chips but U9080 was shorting to ground.
Voltages:
PPBUS_G3H: 5.02V
PP3v3_G3H: 0.00V
PP3v3_G3H_RTC: 0.00V
No short to ground that I can find anywhere, no visible damage, no liquid damage.
Any help is massivly appriciated.
