Default Charging disability

My nex7 2012 dont react on usb cable at all, pc, ac charger, car charger,like there is no cable. But... If i shut down nex, charging will start. Usb connection is dead at all in android when is working but.... OTG pendrive work fine in TWRP, only pendrive, charging is still off. There is battery drain too. There is no adb and fastboot connection but i can install zip from twrp. I try two android and two kernel, still nothing. Any idea?
