Re: Hand controller (paddle)

This is usually a sympton of a dirty potentiometer within the paddle. 
You can easily solve this by opening up the unit and spraying the pot
with a few blasts of a de-greaser/lubricant and then turning the pot
several times to loosen the accumulated grease.

This web page describes the process in detail for an Atari 2600
paddle, but the concept is the same:
