Did you try the conversation of bps2 to bps3 with Hall sensor for the replacement of joystick with potentiometer

Well, it's generally Still part, and according to my knowledge, it's hard/impossible to repair it, unless you have really good electronic specialist. It's expensive and sensitive to rough use.
Once, our specialist (really good one) tried to repair it, but failed.
I'am affraid, you'll have to purchase the new one.
