Check your version of your old lcd back and you must use back the same version if not white screen will appear.

hi
thanks for your help but i'm not new in phone repairs, the display version is the same and the microusb conector is good, there isn't any short circuit.
godok, thanks for the lcd ways, now i think the problem is in the microprocessor.
thanks
