    hello sir i have a note 4 and it just wont power own i try every thing an nothing at first it use to over heat and freeze then one day it went dead however when i connect it to the computer it connect but nothing else could it be the power ic or the capacitors shorts

    • Santosh Das says:

      Overheating means that there is some kind of SHORTING in the PCB. Replace the Battery Connector and Check. If the problem is not solved by Replacing the Battery Connector then clean the PCB with IPA or Alcohol or Petrol and Apply some Hot Air to the PCB and Check. If the problem is still there then the PCB has to be checked for SHORTING.
