Hardware Water Damage and burn holes near LCD driver IC

[OhItsSlick]

here’s some context behind these pictures. I got a switch to repair and upon inspection of the charging port I plugged in the ammeter after seeing that the port looked fine. Next thing I see is the amperage climb up to 2.7 amps at 5 volts and smoke coming out of the switch. I quickly unplug it and open it up. I locate Some liquid damage right beside the LCD FPC connector with some small caps/resistors missing and a hole in the PCB near the VDD Pad of that BGA CHIP. What I’m wondering is, can I replace that cap that would sit above that hole to some other ground pad and just solder a jumper wire to the trace of the VDD pad? I circled a ground pad (3rd pic) that I could use but I’m not sure if all ground pads are equal or if I am in fact safe to place the cap there. Please let me know if you need me to make a bit more sense because this post may seem all over the place. Thanks for reading.

Edit: I replaced M9 after seeing it being shorted and before it wouldn’t turn on at all but now the screen flickers the black light for about a second then turns off.

The backlight turning off might indicate that you still have some water damage on the power rail somewhere.
Most power management ICs have some shutdown features when they get overloaded.
A good clean with isopropyl alcohol might help but water damage usually keeps on corroding.
