Couple of years a go i did a project and built myself an arcade stick. Back then i knew pretty much nothing so i followed an online guide. I used an Ps2 controller pcb and all.
I also used a Happ joystick and Happ pushbuttons.
Now the left side of the stick barely responds anymore… how am i suppose to do my moves ? 
Any tips on repairing it ?
Ah darnit !! when i opened the box… one of my wires soldnerned detached… i feel like chalking the whole thing in the trash…
Post some pictures if possible. It’s probably not that bad. There are people here who sell pre-wired controllers if you need to replace it.
found the problem, my quick disconnect was loose and losing connection… now i need to soldner the wire that ripped back on and im back in the game
