I did a complete teardown of my 26 year old super Nintendo because I had to fix the AV jack. the hardest part was the de soldering. however upon putting it back together I could get the games to play, however it was in black and white…or even a grayish hue…and the controllers didn't work. shortly after the ribbon connecting the controller input to the system snapped on one end. do you think this was the issue, and where do I find a new one? Thanks.
