When I push my R button, sometimes it forces me to lightshield afterwards when I'm not pushing anything. In other words, the analogue on my R button is slightly broken. Any tips on how to fix this?
Also, I'm aware I can plug my controller in with the analogue down to prevent the random light shielding, but I have a triwing so I want to physically fix my controller rather than working around it.
My best controller started doing this like a month or two ago. I'm going to try to fix it once my work bench is accessible again.
Do you feel any kind of resistance when you push the button down, or hear rattling when you shake the controller? If so you might have a broken piece of plastic floating around in there preventing normal operation (this very suddenly happened to me at Genesis II. it sucked! At least it didn't happen in-tournament).
If not, then when you open the controller you'll likely find no visible problems, and my best guess for the culprit is the potentiometer (what VietGeek referred to as "the analogue", I assume) that the triggers slide up and down. I think this because electronics are quite resilient and don't really break down like mechanical things do, so it's very unlikely to be another component on the board. The electrical contact surfaces could get dirty over time, but probably more likely, they might just erode from use.
Cleaning the electrical contacts in the potentiometer might help. There are
specific cleaners for electrical contacts, but if you don't want to bother getting that, rubbing alcohol and a q-tip will work ok (the higher the % of ethanol the better). But the best option would probably just be to replace it, which requires soldering.
I have lots of controller shells, triggers, etc., it is usually the control stick housing that fails, and unfortunately these are not replaceable by themselves so I have to replace the whole circuit board.
They are certainly individually replaceable, I've done so on multiple controllers. Requires soldering; but it's not very difficult once you learn how.
The problem I usually have is getting good replacement sticks to put in in the first place. It's easy to find replacement sticks for PS/360 controllers, but not so much GC. The other day I ordered
an off-brand classic controller, to open it up and see what kind of sticks it has. I know people talk about how bad anything non-nintendo is, but I figured for 5 bucks it was worth a shot. Also I'm not really entirely impressed by Nintendo's sticks; I think they could be better (they're made of plastic after all >_>). Also, I recently found
these, which seem to be GC size. My main concern is the size/shape of the post that the thumbstick slides onto and whether a GC knob could easily be put on there (though, albeit possibly better quality, they're $7 for one, as opposed to $5 for two).
