How do I repair the AV cables that come out of the console?

@thekingmeta use this guide Pac-Man Connect and Play Joystick Switchboard Replacement right up to step #5 here you see the audio and video RCA cable soldered to the board. Desolder the old ones and replace those with some new wires. You can get replacement wires pretty much at any decent hardware store or even a department store.

Nice console to repair and straight forward replacement. While you work on your game console, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.

Repair is War on Entropy!
