Blown PCB board

Hi all,

My first time posting on the forum, so please bear with me if I placed it in the wrong section.

My problem is with the input and outputs at the back of my nvr ( Hikvision DS-7616NI-I2 / 16P NVR)




Don’t ask , but I managed to knack it up, managed to blow the output port side.
The input ports work ok.

so, my question is how or where do I get a replacement PCB for it?

I would be very grateful for any feedback.
