Default [Help] LG G2 Usb port not working

Hi, I need an advise or help regarding my G2's usb port.

Before it was not working, I connected my g2 to my Samsung flat tv to access my video for watch, but sadly it didn't recognized it.
Then I tried charging my g2 but the charging icon isn't showing up.
I tried also connect to laptop, yet no luck. same goes for an OTG cable.

May I know if my usb port is broken? Do anyone here knows how to fix this?

Thank you for reading this and future help that you can give soon.

Regards,
Chonghua
