how to chek & find

I hope you have Power supply

First full down its VOLTAGE and open your phone

NOW:

  1. Attach its Black (-) prod with phone's BSI+Gnd.
  2. Attach its red (+) prod with phone's PCB.
  3. Now up the Voltages slowly
  4. you will see the phone's power automatically will be up
  5. Now you can check that which ic or parts are Hot.
This Hot thing is shot.

Now you can start your process on this shot thing.
