How much to fix Xbox HDMI port

Npt sure.

I would call, to check with the store if, they even fix HDMI ports. I know that GameStop provides an warranty for items but, it replaces the entire system with another system. If you have a warranty from GameStop than the store would replace the entire system for you. However, if your system itself is faulty than you might be better off, contacting Microsoft because they should replace the system for you and attempt to fix any issues and even provide another Microsoft warranty at Microsoft expense.

Depends on witch one the prices defur
