Hori FS3 button doesnt work no more

The triangle button on my Hori FS3 just doesnt work no more, what can do before I decide on buying a new stick to replace, its in realy good shape i dont want ot throw it away + I can stil play some tekken 5 dr SC4 but I mainly use it for capcom fighters. You guys got any tutorial on repairing a HFS3?

There are 2 threads already made for guide/tips on how to mod the FS3.
