Board got liquid damage around JT400, Q5240, CC337.

Found short on PP5V_S2, replaced UP700 and short gone.
Got 5V and 0.04A from charger and I can hear clicking sound on the board - transistor?
Cant locate precise the location of that sound.
Any idea?

PP1V06_S2SW_DRAM - 0.001 in diode mode and 2.5 Ohm to ground

Removed J7740/1 and R770A to check if U7700 is shorted and it is not shorted.
Because PP1V06_S2SW_DRAM going to the RAM any safe suggestion how to find what is shorted?
