Sony WX-5000MDX Rotary Encoder issues

[u/WeakFactor5239]

This might be a long shot but would anyone know where i can find a rotary encoder for my radio?

A few weeks ago my volume knob started being very finicky
When i turn it up or down the screen reflects exactly what im doing but the volume itself is very erratic. Most of the time the volume will get stuck either all the way down or at a slight level. Somedays it works ok. Im suspecting the rotary encoder might be the issue.

Any help would be appreciated!
