Hi,
my macbook air 2018 (A1932) keeps restarting. I have found that lot of caps are shorted around U7800.
(C7814, C7835, C7833, C7815, C7828, C7813, C7827, C7812, C7811, C7823, C7826, C7821, C78C0, C7822, C7824, C7825, C7837, C7834, C7836, C7838) - PPVDDCPU_AWAKE and PP0V82_SLPDDR
Are these caps low resistance or U7800 should be inner shorted? MBA was water damaged but after the clean MBA worked about 10 times but after that keeps restarting after few seconds.
Water damage was aroung Q7680, Q7660, Q7030 and Q7040. I will try next week to replace these mosfets but I dont thinks that it will help.
Thermal cam show some heat aroung U7210 and L7210. I have tried to inject 1V to the L7210 but no short anywhere.
btw: PP5V_G3S voltage falls to 0V during the restart.
Thanks for any help.
