    Default HR92 dial not working

    I have an HR92 here that won't change menus when I turn the dial on top, it feels "clicky" when you turn it, like the rest of the ones I've got, and I've taken it apart to see what's going on, the nylon spigot on the other side of the cog engages with what looks like a small potentiometer on the PCB, so maybe this component has failed or something else has gone wrong. Has anyone else suffered from this or has any ideas if there's a fix?

    It wont be a potentiometer as you can turn it infinitely in either direction.

    From memory it's an infrared optical chopper system - very commonly used in digital knobs which can turn infinitely.
