N00b here. 
I recently started repairing controllers as a bit of a hobby and have successfully solved a number of issues, stick drift of course being the most common. The trick of opening and cleaning the pots and/or replacing the wipers has worked very well overall.
I've come across one very stubborn controller that this is not resolving the problem for though. In fact, I de-soldered and removed the offending pot altogether and yet I am seeing the problem below, which is as it was before I removed the pot.
I don't know quite enough about the circuitry here though to know if this is simply expected behaviour in the absence of the pot and replacing it with another will restore the controller. I plan to add a new one once I have it to hand of course, but wondering if anybody has any experience of this and can comment in the meantime?
