You will probally need a new board but that is hard to say without being there. As far as the replacement goes;don't let all the wires fool ya. Each set of wires has a set number of pins it fits so not only is it difficult to get them wrong but when you put the new board in place the wires will have a memory to them and fall into the place where they hook up. Nothing to it, but get a book and be sure that you need the board first as they are pricey.Good luck
