ipad3 dead PP1V2_soc and PP1V2_S2E short

U8100 tfBga is very hot then
Fisrt step i take out Induktor L8119, L8121,L8105, L8107, L8110 and some capacitor connected with those L.
It seem that the Short leg is the one which not connected to U8100.

then i give voltage at C8121 (no caps on the pcb already) with only 0.3 V the current consumed about 1 Ampere !!!
but unfortunately no part of the PCB is getting hot.

So its really difficult to find where is the problem.

Please master help me solving this.
Sorry for my english
