njsw88:
what about RS Components

njsw88:
what i have found now , that if i put 3v on the VCC of the CH340N chip which is located at U3 on my PCB board which i show on my other post it starts up and i have no more shorts on C2, do you think that this is the problem ?

madires:
How much current is drawn on that external 3V? Are CH340N and C2 connected via some trace?

njsw88:
3v 1amp

madires:
Such a high current is an indication of a shorted component. You could use that and look for a hot component (most likely an MLCC).
