Buffalo Thunderbolt port broken but USB 3 works

Buffalo Thunderbolt port broken but USB 3 works

This drive is out of warranty so my only option would be fixing it if possible. The drive is a Buffalo MiniStation Thunderbolt bus powered drive that also has USB 3.0. The thunderbolt stopped working yet the USB 3.0 works fine. I have two of these drives and the other currently works with thunderbolt. Is there any way to fix the thunderbolt port? Thanks
