Hey all!

So I just got a good deal on a used P4 Pro v2.0, owner did note it had a small crash and camera was not working 100%, everything else seems to be working fine.
I've narrowed the issue down to just the aperture not working, when changing the aperture through controller or app it does not change the exposure (looks to be stuck at 2.8). When I close the aperture I can hear a small gear spinning/ grinding in the camera, this does not happen when I open the aperture.

I'm wondering what is the best way for me to open the camera up so I can check a bit closer. And does anyone know how the aperture inside the camera works/ operates?
Hoping it's a small replaceable gear that's the issue, willing to give it a try so help is appreciated!

Can't seem to find any good videos or forums on how to take apart the camera
