Hi, Connect the phone to a PC (be sure your cable is working). Try to switch it on. If the PC recognizing your device 90% you have a SW problem. Try to restore the phone: Windows 8/8.1 Windows 10 Boot Manager Error Solution If your PC does not respond when you connect the device, then the problem is hardware, broken USB connector, logic board damage… Regards.
You try reset factory?
