I face an issue with my Aquatica housing and i need a help as i cannot solve it by myself (i try lots of different solves but nothing work).
As you can see in the image the red cirlced part is the one that rotate the back control of the camera and change the aperture as well as other controls. This part doesn't function as it has and i have to rotate it lots of times in order to chane it - it spins and glides. I change ths small rubber ring but no solution. I add some more rubber on, nothing. I assume that the problem comes from the green string.
What can i use in order to replace the green string ?
