This happened to me as well. I've had to order a new part, you can get it from China for cheap. Tried to find the item in my mail history, not sure of the name anymore.
Anyway in the end all was fixed, had to solder it on though. Remove old part completely.very frickely job since the two connection points are so close together. You need a small soldering iron and thread. In my case the solder flowed together and I resorted to cutting it apart with a knif directly after.
Keep your patience, and be careful not to break the new part as well.. it will work.
