I have a v7 PS2 here and the controllers do not work. I have checked the controller unit and ribbon cable, which are fine, and have even tried replacing them with brand new ones out of a new PS2. The analog light will light up when the analog button is pressed. None of the buttons work on either controller port. Im fixing this for a friend, and he said only controller port 2 didnt work when he sent it, but when I got it both didnt work. I've double checked the ribbon cable clips and checked for continuity on all pins.
Does anyone have any suggestions on what the problem could be?
