Hi micmac
Send me a pic of your phone and i will returned the solution to you. Then we will post it here.
But fistly you should detect if ther's a short circuit in any power and charge capacitors.
D'ont forget to use a full charged battery and check all mecanical problems ( clean all power related contacts and reflow your phone ).
Goodluck
