Circuit board loose pin - fixable?

I always have had a problem with my temp/fuel gauge not working. Later I found out one the connectors where the IVR gets in is loose, so I disassembled another dash cluster I have in my parts shelf to get the circuit board from but there's a loose pin of the 9 pin connector. Is it fixable or should I consider to buy a new curcuit board?
The best option of course is to fix the loose IVR connection but is that fixable aswell?
