The board is clean, however PPBUS_G3H have a short to ground.
I inject V on that rail and nothing gets warm.

Can you guys help me on that?

Remove F7140 and see if the short is on pin 1 or pin 2. If pin 1, inject away. If pin 2, inspect the board for any of the tantalum capacitors showing goo leaking from them or a crack in any of them.

Usually the big capacitors aside CPU get shorted, however inject voltaje on pin 2 from F7140 and see what gets hot...
