Faulty analog sticks - only up and down axes on left and right
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: [image|1677757] 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=Wokj0D1pbA4&feature=youtu.be 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?
