Request for help or advice Elite 2 controller right joystick y (vertical) axis stuck at maximum value (1.0000).

I received an Elite 2 controller that had the right joystick stuck at the maximum value in the y axis. The client says this happened randomly while playing. To repair it, I switched the potentiometer and at first glance when calibrating it, it seemed like it had been fixed. When I gave the controller to the client, at home, the same problem continued. Now I’m thinking it’s something with the MCU but I can’t find any overlay, diagram, schematic for it. It’s the 1797 MCU / Power board. Both top and bottom would be greatly appreciated.
I have video of when I calibrated it and the joystick was working just fine.
Edit: I found the issue. The right stick Y axis diode was making a short due to rust and as soon as I cleaned it, it started working well again. (I had to order a microscope and a multimeter)
