A2338 820-02020 5V 0.03A clicking noise from L5230 area after liquid

[it-solve]

Extensive liquid around U630, short on RR631/2. Removed them as well as UR630/00, still clicking
Can measure voltage fluctuations on the coil, swinging alot and on same tact.

Replaced U5200 thinking it failed. Still same. Lift up L5230 to see if something afterwards is pulling but can see low voltage jumping on the CHRG_PHASE1 side.
Cant measure any short around the board.

PPBUS_AON - tiny fluctuations - 11.72V
CHRG_PHASE1 - 1.8V fluctuating with the clicking tact

Remove F5200 and check C5250 voltage.
If steady, your problem should be somewhere else, not in the main power supply.

 

[it-solve]

C5250 voltage 12.50V with removed Fuse and no ticking.

Where to next?
