Blackberry 9900 died due to water damage to the phone consumes 70 mA high shorting positions (full. ...?)
try washing her phone first then dry by itself
check all lines VBAT
VBAT C406 and C407 in pa
VBAT C1273 and C1303 pmic
C1201 and C1211 Vsys
Vreg C1228-C1233-C1240-C1247-C1254 and C1272
check the above items one by one and measure again if it still shorting
open its schematic diagram

i give about 4V external suply to board and check mention voltage at mention components .

VBAT C406 , C407 , C1273 , C1303 all ok

and

0mA at other components no Vreg no Vsys....

any idea to next step....

Check green fuses if they are open near PMIC. Those are CPU power line fuses.

i check 3 fuses near pmic they are ok i change one more pmic now its take 200mA on power supply...
