No liquid, no corrosion.
Only suspected area was D3370 and D3302 which had solder balls around.
20V and 0.02A from charger.
F3001 20V on both sides.
U3200 LDOs:
U3200/2 = 1.8V
U3200/12 = 3.37V
U3200/35 = 1.12V
U3200//75 = 1.8V
Found short on PPBUS_G3H.
Removed F7000 and short is on F7000/2 side.
Injected voltage wont heat any component on PPBUS_G3H.
Any idea?
