Repairing Vectrex Controller with bad Buttons 3 and 4

Recently I got a Vectrex but the Controller didn’t work properly :-(

Buttons 3 and 4 don’t react like normal and shooting in Minestorm didn’t make fun.

I opened the controller with some help of the hairdryer and removed the top foil.


Once its open I cleaned the analog stick and case with some alkohol and after cleaning using some vaseline to make ist work propper again.


the pcb is holding via one screw in center. At the edge the pcb is loose and didn’t get the button of 3 and 4 correctly. I used a second screw at the right and the buttons works again like new :-)
