iPhone 5s looks dead but not at all

My Iphone 5s is almost dead, no screen, no vibration, no sound, no apple logo when charging etc... But the phone is able to receive call and text from another device without ringing or vibration or any signs. It also can be restored via Itunes without any problem.

What could be the proplem. No water damage or physical damage I think. Could something like fuse in the motherboard blow cause these problems.

Any help would be greatly appreciated.

Thank you!
