    820-02020 no display fan spin high

    Hi Everyone,

    i am working on macbook pro 820-02020 ex water damage.

    the macbook can turn on but no display and fan spin high.

    after visual check i saw UC710 got burn. took off UC710 but still have short on PPBUS_AON_3V3S2_VIN_ISNS.
    after scraping the short is gone but still have short on PP3V3_S2 and PP3V3_S2_PWR_EN still short.

    i have tried to inject 1V and 3A through this line but nothing gets hot.

    any idea?

          I'm looking for a extreme high current short killer solution for a reasonable cost.

          I have an LGA1700 motherboard (ASUS PRIME Z790-P WiFi) where I exchanged the LGA socket already 3 times, and every time after the socket exchange I get a short of power supply lines VCORE (V variable) and VCCIN_AUX (1.8V).
          After taking off the socket, the shorts dissappear again.
          The soldermask on the socket is already partially demaged from the heat, so I have reconstructed the soldermask by manually painting the missing soldermask parts with a very small top of a...
