My amazing scroll wheel is broken and I'm unsure what to do next.
Your scroll wheel stopped functioning unexpectedly, but you can now control it by moving it horizontally and vertically. It doesn’t move up or down as intended.
It seems the plastic component cracked. (Or maybe luckily the scroll wheel's axle came out.) If your mouse is covered by warranty, submit an RMA to the maker. Otherwise, you can disassemble it and attempt repairs or purchase a replacement.
Typically every mouse I've encountered features a wheel sensor on one side and a solid axle housing on the other. The scroll wheel includes "pins" protruding from the center on both sides, which fit into these two areas (one inside the sensor, the other on top of the housing). Should either pin not be securely placed in these slots, the wheel might malfunction. If the pins on either side of the wheel are damaged or missing, your mouse is defective.
Each mouse has its own characteristics, yet generally the circuit board and scroll wheel assembly reside in the lower section. The scroll wheel typically features a central axle encased within a frame, which secures it firmly. When you press down to activate the scroll wheel, it usually tilts slightly and engages a small switch on the opposite side. Inspect the region surrounding the scroll wheel closely, searching for any signs of cracks or misalignment.
Notice the white section pointing toward your right mouse button—it resembles the axle around which your scroll wheel rotates. There should be a component securing it (possibly molded into the upper part of the mouse). The area beside your left button is the rotary encoder, which detects the wheel's spin. You’ll likely see a small protrusion on the opposite side of the scroll wheel axle that fits into it or meshes with a cog on the encoder. A better view of this feature would aid in diagnosing any issues. It seems you’re positioning the phone too close to the camera lens; try moving it back and zooming in for sharper images.
Oof, it seems the connection between the wheel and the encoder is missing. Even if the component remains inside and you manage to reattach it perfectly, there isn't enough space for the glue to stick properly. It's time to switch to a new mouse. F (The photos looked much clearer this time!)
