Hello Im trying to repair controler (magma red version) with faulty analog sticks. Only vertical axes are dysfunctional -they go both “up“. I connected them to PC and its shows me this in neutral position:
Also if i put some pressure to right stick - like almost hitting R3 it then stabilizes like it should work in neutral position - and funny thing - pushing it also affects the What i tried to do is clean potentiometer “disks” on both those axes. It didn’t changed anything. However sticks look like they are covered in some… slime or oil. I recorded it and sent it to youtube. https://www.youtube.com/watch?v=Wokj0D1p… If you look closely you can see its almost glowing. So my question is - is it some kind of oil or lubricant put on purpose or can it be soda someone spilled out? I opened about 3 or 4 dualshocks and have never seen something like that - however i havent yet seen sticks with black plastic parts - only those “white and green type” I also found something like this near charging port and i was able to scracth it from PCB (no harm done). So if it is some soda how can i clean it?
I had something similar happen recently to one of my controllers. I did basically the same thing you did only I de-soldered the whole stick to clean the potentiometers, but did not get any improvement. The only thing which worked for me was to de-solder the whole analog stick assembly and solder in a new one. As a side not I also saw a goo on my sticks, but after replacing the stick and getting a better look at the stuff I just decided it was some kind of lubricant from the factory.
