Faulty analog sticks - only up and down axes on left and right
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.
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?
