Xbox One with Controllers authentic

Product Name: Xbox One with Controllers authentic
The system has a faulty HDMI port as I was told. May have other issues. Device turns on just fine, but it will not display any image on the screen. I was authentic told by store that it's the HDMI port. Wanted to add that the device has no physical damage, any damage is internal & may be costly to repair, if even able to repair at all. Controllers however are fully functional, will sell them separately at a lower price if interested. Willing to negotiate price.
