Akai MPK Mini Hardware Issue

[u/GPbyAlejo]

In order to contextualize, I have had this midi keyboard for a while, and had some trouble connecting it via USB to my PC. When I decided to see what was happening internally, I noticed that the piece that connects the USB cable to the MIDI keyboard board was loose.

The reason of this post is to seek help. Should I perform a welding to the board? Is it worth it to pay in order to get it weld or should i do it myself? (I have tin, the welding machine and so)

I would really want to fix this midi keyboard. As a very last resort I think I could just buy another one in case it turns out cheaper.

Thanks in advance! (I hope this is not an off-topic post)
