Part 4/8:
During the teardown, it became apparent that the device was designed in a way that didn't lend itself easily to repairs. However, this exploration provided insights into its construction and the critical components that allow the potentiometer to function correctly.
Diagnosing the Fault
As it turned out, the issue was not electronic but mechanical. In simple terms, the potentiometer had lost its ability to operate due to wear and tear on its internal components. It became clear that significant effort would be required to address the mechanical failure, relying more on practical skills than theoretical electrical knowledge.
