Atari CX10 Controller: Won't Go Left FIXED!! 

This is the original model controller that came with the first run of Atari VCS (2600) machines. Also known as Heavy Sixers.
The controller would not send a signal to go left. The problem in this instance was the plug had become dirty or corroded in that particular hole. The video contains the solution to fix that problem.
You do not need to take the controller apart to clean the plug out.
