I needed a DualShock controller for my restored PlayStation 1 so I wanted to do a restoration and repair for one. I got my hands on this abandoned DualShock controller for the PS1. It was sold to me as working but, as usual it was broken… The shell is also quite badly yellowed and dirty. Couple of the screws on it were rusted.
I tested the controller and with the help of another Controller I was able to get to the options and found out that the X button is pressed down all the time. I was able to test most of the other buttons at this point, but this was the only issue I found. The analog sticks and the vibration were also working.
I opened the controller and took all the parts out. There was some grime around the buttons on the inside but all in all the housing seems quite dirt proof. After taking everything apart I could see the issue with the X button. The rubber pads that press the have a graphite pads which allow controller to recognize when the button is pressed. Some of this graphite had stuck to the circuit board. This had formed a “bridge” on the circuit making it think the X is pressed down. Eventually this problem would occur with the other buttons as well but I guess X is the most pressed button on the controller since this seems to be a common issue, and it’s always the X button.
I used some isopropyl alcohol to clean up the circuit and all the other parts. This was enough to fix the issue. All the plastic parts were washed with soap. They the gray parts were submerged in hydrogen peroxide and left in UV-light for 12 hours. This process is called “retrobrighting” there are several ways of doing it. This submerging method is the easiest but hydrogen peroxide is not free so you might want to use some other method for one project. However, I do this occasionally, doing it like this is worth it for me. The hydrogen peroxide can be reused but in time the solution will dilute and the reaction time will slow down. My previous Game restoration videos show other methods of doing this. The methods typically require H2O2 and UV-light.
I had repaired and cleaned the controller I put it back together and tested it. While I was putting it in I also thought it would be cool to show how the vibration engines work. After all that’s what made this controller special at the time.
