Hacking Joystick issues

[MagicUkulele]

So I recently noticed a major drift issue on my right joystick; opening VitaTester showed the right joystick has input (0,222) at rest. I tried replacing the joystick which hasn't fixed the issue. Now I've replaced the whole R button controller board (which the joystick plugs into) and I still have the same issue... When I leave the joystick disconnected, the input returns to normal (around 125,125). Really not sure what the issue is without replacing the motherboard. Does anyone have any ideas?

Edit: Fixed it... spotted some corrosion on the main motherboard. Bit of alcohol and a soft brush and the joystick now functions as normal.

Yeah Psvita analog stick are virtually the same tech as switch ones. They tend to get dirty and drift. Stardew Valley has no dead zone so you notice immediately.
